Executive Summary<br />

NOTE BY KU-RING-GAI COUNCIL:<br />

ALL REFERENCES TO AND DIAGRAMS OF SUBDIVISION LOTS, NUMBERS<br />

AND LOCATION DO NOT FORM PART OF THIS PLANNING PROPOSAL<br />

Background: UBM <strong>Ecological</strong> Consultants (‘UBM’) has been retained by the Proponent Mr Peter Borbilas of<br />

Bellevue Projects Pty Ltd undertake ecological investigations in support of a Planning Proposal application to<br />

Ku-ring-gai Council to rezone the Subject Property Lot 1 in DP 375262 at 35 Water Street Wahroonga from<br />

5(a) Special Uses (Hospital) to E4 Environmental Living Zone.<br />

Ku-ring-gai Council is in the process of preparing a new Principal Local Environmental Plan (‘LEP’) to replace<br />

the Ku-ring-gai Planning Scheme Ordinance (‘KPSO’). The draft LEP has not yet been exhibited, however it is<br />

understood that it is proposed to rezone the Subject Property part R2 Low Density Residential and part E4<br />

Environmental Living. When the draft LEP is finalised and gazetted, the proposed E4 Environmental Living<br />

Zone for the Subject Property would be subsumed into the new LEP.<br />

The existing zoning of the land allows for ‘hospitals’ but does not allow residential subdivision. The E4<br />

Environmental Living Zoning would permit limited residential development, subject to a minimum Lot size of<br />

2,000 m 2 , the conservation of the ecological heritage values of the site and retention of neighbourhood<br />

character and amenity (Ingham Planning 2013).<br />

Two thirds of the Subject Property has been identified by Ku-ring-gai Council (Draft LEP 218) as part of a<br />

larger area considered to have biodiversity significance. This assessment is based on the presence of the<br />

‘critically endangered’ Blue Gum High Forest (‘BGHF’) on the Subject Property; represented predominantly<br />

by stands of remnant trees - Sydney Blue Gum (E. saligna). However, there is sufficient land outside the<br />

primary ecological conservation areas and the primary heritage curtilage of Rippon Grange to enable the<br />

creation of a small number of residential lots. A limited residential development of the site in this manner<br />

will have significantly less heritage, ecological and neighbor impacts than the large hospital buildings that<br />

have been approved over a substantial portion of the site.<br />

The current Report has been prepared at the request of the Proponent and assesses the conservation<br />

significance of the native vegetation known to occur within the Subject Property in regards to the current<br />

State and Commonwealth environmental legislation. The potential impacts of the current rezoning<br />

application and of any future limited development on the Subject Property have also been considered.<br />

The presence of remnant BGHF within the Subject Property established by previous workers is confirmed.<br />

The extent of this ecological community on the Property has been determined by the NSW Land &<br />

Environment Court (Proceedings 11193 of 2006) to be 6,350 sq metres (0.635 ha), and this area has been<br />

adopted in this Report (see Figure 1.3).<br />

The remnant BGHF in the Subject Property now comprises individuals and small stands of native canopy<br />

trees over a predominantly exotic/weedy understorey. These areas are hereafter described in this <strong>Ecological</strong><br />

Report as ‘BGHF Habitat’ in order to distinguish the vegetation from a viable BGHF ‘ecological community’,<br />

which is typically floristically diverse and structurally intact (see Final Determination TSC Act, Appendix 1).<br />

Given the considerable number of flora and fauna surveys which have been conducted for the whole of the<br />

2.1318 hectares of the larger Subject Property since 2005 (see Section 6 References), it was not considered<br />

<strong>Flora</strong> & <strong>Fauna</strong> <strong>Survey</strong> & <strong>Ecological</strong> <strong>Assessment</strong>s – 35 Water Street Wahroonga<br />

necessary to replicate these earlier studies. This Report therefore focuses on the conservations significance<br />

of those parts of the Subject Property which may be the subject of a future development application – i.e.<br />

area substantially outside the mapped BGHF Habitat, as determined by the Land and Environment Court<br />

(2006).<br />

It is proposed to retain historic Rippon Grange, its curtilage and part of the culturally significant gardens.<br />

The house will be restored and used as a family residence. However, there are two (2) areas outside<br />

potentially suitable for environmentally sensitive limited future residential development.<br />

Area 1 is located in the south-western part of the Subject Property wholly outside the area mapped as BGHF<br />

Habitat (see Figure 1.3).<br />

Area 2 is located in the south-eastern corner of the Property, with part of this area abutting the mapped<br />

Core BGHF Habitat area (see Figure 1.3). <strong>Ecological</strong> investigations presented in this Report focus on the<br />

natural conservation values of Area 2, likely to be subject of a future limited development application.<br />

Results – <strong>Flora</strong>: A total of 170 flora species was recorded for the eight (8) transects established in four (4)<br />

Subject Sites in the south-eastern corner of the Subject Property and described in this Report as Area 2 (see<br />

Figure 1.3). A total of 220 flora species was recorded in the 11 quadrats established in the nearby BGHF<br />

Habitat Area (see Section 3.3).<br />

More introduced species than natives were recorded throughout the area surveyed. Approximately 75% (in<br />

8 transects) and 79% (in 11 quadrats) recorded were horticultural introductions, non-indigenous native<br />

species (i.e. planted specimens) or weeds. Thirteen (13) plants recorded Sites are declared as ‘noxious<br />

weeds’ in Ku-ring-gai Local Government Area.<br />

Under the draft concept design (see Figure 1.4), the potential loss of BGHF Habitat in the proposed future<br />

development area has been calculated at 173 sq metres, which is only 2.74% of the total area of BGHF extant<br />

within the Subject Property. Eleven (11) BGHF trees are likely to be removed or otherwise impacted under<br />

the development proposal.<br />

Results – <strong>Fauna</strong>:<br />

Previous surveys have identified a total of 24 native birds, six (6) native mammals, four (4) reptiles and two<br />

(2) amphibians within or nearby the Subject Property. Of these, the Gang-gang Cockatoo and Grey-headed<br />

Flying-fox are listed under the TSC and/or EPBC Acts.<br />

By the completion of the current field survey (May/June 2012), eight (8) bird species were detected within,<br />

adjacent to, or flying over the Subject Property; the latter identified by their distinctive calls as well as<br />

observation (Table 4.2). The Powerful Owl (Ninox strenua) is listed as ‘vulnerable’ under the TSC Act and was<br />

heard calling from outside the Subject Property during nocturnal surveys.<br />

Two (2) native mammalian species were observed on the Subject Property; the Common Ringtail Possum<br />

(Pseudocheirus peregrines) and Swamp wallaby (Wallabia bicolour).<br />

Three (3) species listed under the TSC and/or EPBC Acts have been recorded in the vicinity or flying over the<br />

Subject Property during field investigations. Although not observed within the Subject Property, there are<br />

UBM <strong>Ecological</strong> Consultants Pty Ltd<br />

some suitable resources available for these species. Therefore, the Seven-part Test of Significance has been<br />

applied under the precautionary principle for the following species:<br />

Grey-headed Flying-fox (Pteropus poliocephalus)<br />

Gang-gang Cockatoo (Callocephalon fimbriatum)<br />

Powerful Owl (Ninox strenua)<br />

These <strong>Assessment</strong>s (see Section 4.5) have indicated that there would be NO SIGNIFICANT IMPACT on any of<br />

the threatened species listed above as the result of the Planning Proposal.<br />

Conclusions & Recommendations:<br />

Future development in Area 2 may have some minor impact on the mapped Core BGHF Habitat, depending<br />

on project design; these being limited to parts of potential Lots 3 and 4 in Area 2. The remaining potential<br />

Lots 2 and 5 are located wholly outside the mapped BGHF (see Figure 1.4).<br />

There is however, an opportunity to redesign the limited development in Area 2 so that no area of BGHF<br />

Habitat is impacted. This will be addressed if and when the current proposal rezoning is approved, and<br />

before a development application is submitted. However, for the purposes of the current Report, the draft<br />

concept subdivision plan which considers the potential to establish three (3) Lots in Area 2 will b considered<br />

(see Figure 1.4).<br />

If the subdivision proposal is adopted as envisaged in the subdivision concept plan accompanying the<br />

Planning Proposal, there is likely to be a loss of 173 sq metres of modified BGHF Habitat from Area 2. This<br />

represents a loss of 2.74 % of the total area of BGHF Habitat in the Subject Property (@ 6,530 sq metres).<br />

Accordingly the Seven-part Test of Significance has been undertaken as per Section 5A of the NSW<br />

Environment Planning & <strong>Assessment</strong> Act 1979 (see Section 3.6).<br />

This <strong>Assessment</strong> has concluded that the loss of 173 sq metres out of a total area of 6,350 sq metres of BGHF<br />

Habitat in the Subject Property (2.74%) is not ‘significant’ in terms of the legislation, and therefore it will not<br />

be necessary to refer the matter to the Minister for Environment & Heritage for future consideration in a<br />

Species Impact Statement relating to flora issues 1 .<br />

It should however, be noted that the loss of 2.74% of BGHF under the future subdivision proposal compares<br />

favourably with the 4.9% loss of this community which would have occurred under the approved Hospital<br />

development. Under the future subdivision proposal envisaged in the subdivision concept<br />

planaccompanying the Planning Proposal, 6,177 sq metres of BGHF would be retained, rehabilitated and<br />

appropriately managed. This compares to only 6,034 sq metres of the community which would have been<br />

retained under the Hospital development proposal (a net gain of 143 sq metres)<br />

1 Note that a Species Impact Statement was prepared in support of the earlier approved hospital development<br />

(Cumberland Ecology 2007). This SIS considered impacts to a significantly larger area of BGHF Habitat than the current<br />

draft Proposal.<br />

UBM <strong>Ecological</strong> Consultants Pty Ltd<br />

<strong>Flora</strong> & <strong>Fauna</strong> <strong>Survey</strong> & <strong>Ecological</strong> <strong>Assessment</strong>s – 35 Water Street Wahroonga<br />

It is however, recommended that the loss of 173 sq metres of BGHF, although small, should be ‘offset’<br />

against a restoration and management program to rehabilitate the remaining Core BGHF within the Subject<br />

Property.<br />

A Vegetation Management Plan for the restoration and management of BGHF Habitat at 35 Water Street has<br />

been prepared (UBM 2007); approved by DECCW/OEH, and adopted by Ku-ring-gai Council. This Plan<br />

provides for bush regeneration works over a period of at least five (5) years and will guide on-ground<br />

bushland restoration and rehabilitation works in the area mapped as Core and Non-Core BGHF Habitat. This<br />

Plan includes those areas of BGHF Habitat which intrude marginally into possible new Lots 3 and 4, inArea 2.<br />

Scientific Licence 132C for the purposes of science, education or conservation under the National Parks &<br />

W8ldlife Act 1979 has been obtained from the Office of Environment & Heritage (OEH) to provide for the<br />

implementation of works. However to date, no works under this Plan have been undertaken. Scientific<br />

License 132C is currently in the name of the previous landowner Waterbrook Pty Ltd, so it will be necessary<br />

to apply to the Licensing Division of OEH to reissue the License in the name of the current landowner<br />

Bellevue Projects Pty Ltd. All other licence conditions will remain unchanged.<br />

Further, it is also recommended that those parts of the Subject Lots located outside the Development Zone<br />

(i.e. house footprints and driveways) and adjoining the Core BGHF (as mapped) be rehabilitated and<br />

thereafter maintained as closely as possible in a ‘near natural’ condition.<br />

It is considered that the implementation of the adopted Vegetation Management Plan (UBM 2007) for the<br />

remaining 1,677 sq metres of BGHF Habitat in the Subject Property, and the rehabilitation of the simplified<br />

and modified BGHF adjoining the Core BGHF (as mapped) will serve to provide an adequate ‘offset’ for the<br />

loss of~173 sq metres of BGHF in the Area 2 potential development area.<br />

Further, the loss of only 2.74% of BGHF Habitat within the Subject Property is well within the maximum 5%<br />

loss for BGHF proposed by Dr P. Smith as an expert witness appearing in the Land and Environment Court<br />

and adopted by the Court (Proceedings 11193 of 2006).<br />

Similarly, the loss of a small area (173 sq metres) of habitat which could potentially be utilised by the<br />

threatened species, the Grey-headed Flying-fox, Gang Gang Cockatoo and Powerful Owl is not considered to<br />

be significant to the species, populations or habitats.<br />

The Planning Proposal and potential future subdivision, as envisaged by the concept plan submitted with the<br />

Planning Proposal, will result in the restoration of historic Rippon Grange, its gardens and arboretum, and<br />

allow for the conservation and future management of the critically endangered BGHF on the Subject<br />

Property.<br />

Characteristic vs. Diagnostic Species - Characteristic species are those typically found in the subject plant<br />

community but which may also be found in a number of other plant communities, e.g. Pittosporum<br />

undulatum, Microlaena stipoides, Pratia purpurascens, Dichondra repens, Entolasia spp, Oplismenus spp etc.<br />

Diagnostic species are those that indicate the type of plant community present and which are usually limited<br />

to the subject community or to a narrow range of communities which have similar or related habitat<br />

requirements. Examples might be Blue Gums indicating BGHF, Sydney Turpentine indicating Sydney<br />

Turpentine Ironbark Forest, Grey Box indicating Cumberland Plain Woodland or Shale Gravel Transition<br />

Forest. Some commonly occurring species are characteristic of quite a few plant communities,<br />

Direct Impacts are those that directly affect the habitat and individuals. They include, but are not limited to,<br />

death through predation, trampling, poisoning of the animal/plant itself and the removal of suitable habitat.<br />

Indirect Impacts occur when project-related activities affect species, populations or ecological communities<br />

in a manner other than direct loss. Indirect impacts can include loss of individuals through starvation,<br />

exposure, predation by domestic and/or feral animals, loss of breeding opportunities, loss of shade/shelter,<br />

deleterious hydrological changes, increased soil salinity, erosion, inhibition of nitrogen fixation, weed<br />

invasion, fertiliser drift, or increased human activity within or directly adjacent to sensitive habitat areas.<br />

<strong>Ecological</strong> Community – described as an assemblage of species occupying a particular area at a particular<br />

time, e.g. as set out in the Final Determinations of the Scientific Committee<br />

1 INTRODUCTION<br />

1.1 Background Information<br />

UBM <strong>Ecological</strong> Consultants (‘UBM’) has been retained by the Proponent Mr Peter Borbilas of Bellevue<br />

Projects Pty Ltd undertake ecological investigations in support of a Planning Proposal application to Ku-ringgai<br />

Council to rezone the Subject Property Lot 1 in DP 375262 at 35 Water Street Wahroonga from 5(a)<br />

Special Uses (Hospital) to E4 Environmental Living Zone.<br />

Ku-ring-gai Council is in the process of preparing a new Principal Local Environmental Plan (‘LEP’) to replace<br />

the Ku-ring-gai Planning Scheme Ordinance (‘KPSO’). The draft LEP has not yet been exhibited, however it is<br />

understood that it is proposed to rezone the Subject Property part R2 Low Density Residential and part E4<br />

Environmental Living. When the draft LEP is finalised and gazetted, the proposed E4 Environmental Living<br />

Zone for the Subject Property would be subsumed into the new LEP.<br />

The existing zoning of the land allows for ‘hospitals’ but does not allow for residential subdivision. The E4<br />

Environmental Living Zoning would permit limited residential development, subject to a minimum Lot size of<br />

2,000 m 2 , the conservation of the ecological heritage values of the site and retention of neighbourhood<br />

character and amenity (Ingham Planning 2013).<br />

Two thirds of the Subject Property Lot 1 has been identified by Ku-ring-gai Council (Draft LEP 218) as part of<br />

a larger area considered to have ‘biodiversity significance’. This assessment is based on the presence of the<br />

‘critically endangered’ Blue Gum High Forest (‘BGHF’) on the Subject Property: this community represented<br />

predominantly by stands of remnant Sydney Blue Gum (E. saligna) canopy trees. However, there is sufficient<br />

land on the Subject Property outside the primary ecological conservation areas and the primary heritage<br />

curtilage of Rippon Grange to enable creation of a small number of residential lots.<br />

The presence of remnant BGHF within the Subject Property established by previous workers is confirmed.<br />

The extent of this ecological community on the Property has been determined by the NSW Land &<br />

Environment Court (Proceedings 11193 of 2006) to be 6,350 sq metres (0.635 ha), and this area has been<br />

adopted in this Report (see Figure 1.2).<br />

Given the considerable number of flora and fauna surveys undertaken for the whole of the 2.1318 hectares<br />

of the Subject Property since 2005, it was not considered necessary to replicate these earlier studies,<br />

especially for those areas mapped as Core BGHF. This Report therefore focuses on the conservation<br />

significance of those parts of the Subject Property which may be the subject of a future development<br />

application – i.e. areas outside the mapped Core BGHF, as determined by the Land and Environment Court<br />

(2006).<br />

The current Report- <strong>Flora</strong> and <strong>Fauna</strong> <strong>Survey</strong> and <strong>Ecological</strong> <strong>Assessment</strong>s for Blue Gum High Forest at 35<br />

Water Street Wahroonga – will, where applicable, update and expand the findings of a number of earlier<br />

surveys and reports prepared for the Subject Property; these earlier reports having been undertaken on<br />

behalf of former Department of Commerce and latterly, the former owners Waterbrook Pty Ltd (see Section<br />

3.1.1 and Section 6 References) for a list of previous reports).<br />

1.2 Site History<br />

The Subject Property (Lot 1 in DP 375262) is part of a historic property known as Rippon Grange. The<br />

Property is 2.1318 hectares in size, with frontages to Water Street and Young Street and is located within the<br />

fully developed residential suburb of Wahroonga. The Property is currently zoned Special Uses 5(a) Hospital<br />

Rippon Grange was constructed as a two (2) storey private dwelling in 1898 and is the main building on the<br />

Subject Property, although a number of significant outbuildings and important landscape elements remain in<br />

situ. Rippon Grange has been classified by the National Trust of Australia (NSW), and it is also listed as an<br />

‘Indicative Place’ on the Australian Heritage Commission’s Register of the National Estate.<br />

In the early 1950s, Rippon Grange was donated to the NSW State government for use as a Hospital,-and it<br />

continued to serve this function - latterly as the John Williams Respite Care Centre - until 2002 when it was<br />

declared ‘surplus to needs’.<br />

In 2005, the State Property Unit of the NSW Department of Commerce commissioned a preliminary<br />

investigation of ecological issues and an opportunities and constraints study (UBMC February 2005), which<br />

identified the presence of ~2,600 sq metres (0.26 ha) of simplified and modified Blue Gum High Forest on<br />

the Property.<br />

On June 30 2005, the Subject Property was acquired by Waterbrook Pty Ltd with the intention of<br />

redeveloping the Property under State Environmental Planning Policy (Senior Living) 2004. Subsequent<br />

ecological surveys carried out on behalf of Waterbrook (UBMC February 2006) confirmed the findings of the<br />

earlier ecological investigations. At that time, Blue Gum High Forest in the Sydney Basin Bioregion was listed<br />

under the Schedules of the NSW Threatened Species Conservation Act 1995 (hereafter ‘TSC Act’) as an<br />

‘Endangered <strong>Ecological</strong> Community’, and as ‘Threatened’ under the Commonwealth Environment Protection<br />

of Biodiversity Conservation Act 1999 (hereafter ‘EPBC Act’).<br />

Since the acquisition of the Subject Property by Waterbrook in mid-2005, the ecological status of the Blue<br />

Gum High Forest has been reviewed by the NSW Scientific Committee established under the TSC Act; with<br />

this community now being declared as a Critically Endangered <strong>Ecological</strong> Community (‘CEEC’)’ (see Final<br />

Determination 20 April 2007, Appendix 1). Of most import, the criteria for identifying the Blue Gum High<br />

Forest ecological community were also amended, thus providing for a larger proportion of the Subject<br />

Property to be reclassified as BGHF.<br />

As the result of these changes to the legislation, Ku-ring-gai Council and the then-National Parks & Wildlife<br />

Group of the Department of Environment & Climate Change 4 (‘DECCW’) required Waterbrook to review and<br />

reassess the extent of the remnant BGHF extant at 35 Water Street, Wahroonga.<br />

Subsequent investigations by Smith & Smith on behalf of Ku-ring-gai Council (December 2006) then revised<br />

the area of BHGF extant on the Subject Property from the original 2,600 sq metres (0.26 ha) mapped by<br />

UBMC (2005) to 6,350 sq metres (0.64 ha) (see Figure 1.2).<br />

4 DECCW is now the Office of Environment & Heritage within the Department of Premier & Cabinet.<br />

UBM <strong>Ecological</strong> Consultants Pty Ltd Page 3


<strong>Flora</strong> & <strong>Fauna</strong> <strong>Survey</strong> & <strong>Ecological</strong> <strong>Assessment</strong>s – 35 Water Street Wahroonga<br />

The method used by Smith & Smith (2006) to determine the extent of the BGHF at Rippon Grange was to<br />

draw a line around the outside canopy line of each of the large Sydney Blue Gums (Eucalyptus saligna) on<br />

the Property and to call this area BGHF, regardless of the nature of the understorey. Polygons were then<br />

joined together to arrive at the larger area of 6,530 sq metres (see Figure 1.2).<br />

The extended area of BGHF was subsequently approved by a Hearing in the NSW Land & Environment Court<br />

(No 11193 of 2006). Therefore, in view of the Court’s decision, the larger area of 6,350 sq metres of BGHF<br />

was adopted as a base point for all subsequent reports and investigations, including the Vegetation<br />

Management Plan prepared to guide the restoration and future management of the BGHF in the Subject<br />

Property (UBM December 2007).<br />

1.3 The Planning Proposal<br />

A Planning Proposal Report has been prepared by Ingham Planning Pty Ltd (January 2013) for the Subject<br />

Property Lot 1 DP 375362, 35 Water Street, Wahroonga. This Planning Proposal involves an amendment to<br />

the existing KPSO zoning map to change the zoning of the Subject Property Lot 1 from 5(a) Special Uses –<br />

Hospital to E4 Environmental Living.<br />

The E4 Environmental Living Zoning would permit limited residential development, subject to a minimum Lot<br />

size of 2,000 m 2 , conservation of the ecological heritage values of the site, and retention of neighbourhood<br />

character and amenity (Ingham Planning 2013). A limited residential development of the site in this manner<br />

will have significantly less heritage, ecological and neighbor impacts than the large hospital buildings that<br />

have been approved over a substantial portion of the site.<br />

The rezoning of the Subject Property will provide for a future development application to Ku-ring-gai Council<br />

to subdivide a limited number of residential allotments in the southwest and southeast corners of the site,<br />

together with a large a) residual Lot containing the heritage-listed buildings and gardens (see Figure 1.3). A<br />

development application for subdivision will be prepared if and when Council indicates support for the<br />

proposed re-zoning.<br />

Assuming the rezoning proposal is approved, the future subdivision of land at Rippon Grange is generally<br />

proposed as follows:<br />

The Heritage Precinct - proposed new Lot 1 will include Rippon Grange and its outbuildings, landscaped<br />

gardens, and a large part of the 19th Century arboretum. The house, which is in a derelict condition, will be<br />

restored and utilised once again as a family residence.<br />

The Potential Development Land - comprises two (2) areas with the potential for environmentally sensitive<br />

limited future development.<br />

Area 1 is located in the south-western part of the Subject Property (see Figure 1.3).<br />

Area 1 can accommodate a a large battle axe block and will include a new driveway from Water<br />

Street running along the western boundary, and a residential Lot sited to the rear of the Property;<br />

i.e. in the south-western corner formerly used as a poultry yard, composting and service area. Lot 2<br />

will be 2,070 sq metres (~0.021 ha) in size, does not include any area mapped as BGHF.<br />

Area 2 is located in the south-eastern corner of the Property, with part of this area abutting the mapped<br />

Core BGHF area (see Figure 1.3).<br />

Area 2 can accommodate up 3 lots frontingYoung Street. Potential Lots 3 and 4 can be accessed by a<br />

common driveway servicing both Lots. Both these Lots incorporate parts of the arboretum, but they also<br />

intrude marginally into the area mapped as BGHF (Smith & Smith 2006, UBM 2007). Lot 3 will be 940 sq<br />

metres (0.094 ha) and Lot 4 will be 1,290 sq metres (0.129 ha) in size. Lot 3 has 572 sq metres of BGHF,<br />

of which 77 sq metres (23 sq metres building and 54 metres driveway) would be affected. Lot 4 has 987<br />

sq metres of BGHF, of which 96 sq metres (27 sq metres building and 69 sq metres driveway) would be<br />

affected.<br />

UBM <strong>Ecological</strong> Consultants Pty Ltd Page 5


<strong>Flora</strong> & <strong>Fauna</strong> <strong>Survey</strong> & <strong>Ecological</strong> <strong>Assessment</strong>s – 35 Water Street Wahroonga<br />

A potential third lot within Area 2 (Lot 5) is located in the lower SE corner of the Property, adjacent to<br />

the rear gate and driveway on Young Street. It will be located partly on the paved car park which<br />

serviced the former Nurses Quarters on Billyard Avenue, and will incorporate part of the arboretum. Lot<br />

5 will be 1,110 sq metres (0.111 ha) in size. Lot 5 has 353 sq metres of BGHF, of which none would be<br />

affected (calculations courtesy Tanner Architects, pers. comm.).<br />

NOTE: There will be an opportunity to redesign the proposed new Lots in Area 2 so that no area of BGHF is<br />

impacted or the area of impact is reduced. This will be addressed if and when the current rezoning proposal<br />

is approved and before a development application is submitted. However, for the purposes of the current<br />

Report, the draft concept project design which considers the maximum potential to establish three (3) Lots<br />

in Area 2 will be considered in detail (see Figure 1.4).<br />

The subdivision concept plan submitted with the Planning Proposal (see Figure 1.3) provides for services to<br />

potential new Lots 3,,4 and 5 (drainage and sewage facilities) in Area 2 to be installed along the southern<br />

Property boundary; these being located outside the mapped BGHF Habitat area. Alternately, all services will<br />

be installed on the common driveway from Young Street. It is anticipated that no impact to the BGHF is<br />

result as a result of the installation of services.<br />

An Arboricultural Impact <strong>Assessment</strong> Report prepared by Tree Wise Men (October 2007) in support of a<br />

previous Development Application identified 342 trees in the Subject Property, and of these, a small number<br />

are species considered to be ‘characteristic’ of the BGHF <strong>Ecological</strong> Community (see Appendix 1). The<br />

remaining trees are horticultural introductions or non-indigenous native plantings.<br />

While some of the characteristic BGHF trees are remnant (i.e. naturally occurring), others have been planted<br />

in the landscaped grounds. Large native canopy trees, particularly Sydney Blue Gum (Eucalyptus saligna)<br />

have been widely used as landscape features in the Locality, occurring as street trees, in neighbourhood<br />

parks and in private gardens<br />

A Preliminary Tree Impact <strong>Assessment</strong> Report has been prepared by Tree Wise Man (October 2011) in<br />

support of the future concept subdivision proposal. This <strong>Assessment</strong> suggests that eight (8) BGHF trees will<br />

be removed or otherwise impacted under the subdivision proposal. However of these, two (2) specimens<br />

are mature Pittosporum undulatum (Sweet Pittosporum) – a small native tree known to occur is most plant<br />

communities in SE NSW and widely considered by bush regenerators to be a ‘native weed’ (UBMC 2006,<br />

UBM 2007. ). Five (5) of the BGHF trees likely to be impacted have been identified for proposed Lot 3 and<br />

one (1) tree for proposed Lot 4 (see Appendix 3). Another 27 introduced (exotic) trees or large shrubs will<br />

also be impacted, with the majority of these being located in proposed Lot 2, which is part of the landscaped<br />

garden and arboretum and located outside the area mapped as BGHF (Smith & Smith 2006, UBM 2007).<br />

In order to reduce any potential impacts on the BGHF trees on potential Lots 3, 4 and 5, within Area 2, the<br />

development footprint for each allotment has been sited towards the front of the Lot, in what are essentially<br />

open lawns with scattered trees. Pending advice from the new Project Arborists Landscape Matrix (report<br />

December 2011) the configuration of the development footprints will be adjusted to protect any significant<br />

trees which may occur.<br />

- to prevent loss of local native biodiversity on<br />

public and private lands by<br />

eliminating/ameliorating threatening processes<br />

- to protect, enhance and where appropriate,<br />

increase local biodiversity on public and private<br />

lands<br />

- to protect and enhance aquatic and terrestrial<br />

ecosystems and habitats and connectivity<br />

between reserves.<br />

The Vegetation Management Plan prepared for the<br />

2 SITE DESCRIPTION<br />

2.1 Location and Setting<br />

Historic Rippon Grange is located in a fully developed residential setting in the suburb of Wahroonga, in Kuring-gai<br />

Local Government Area. It is about one (1) kilometre from the Wahroonga Shopping Centre and<br />

Railway Station and about 22 kilometres north-west of the Sydney CBD.<br />

The suburb of Wahroonga was developed in the late 19 th Century, soon after the railway line was extended<br />

to Sydney’s Upper North Shore (c. 1890). For many years, it was used as a private dwelling, and during that<br />

time the grounds were developed and extensively landscaped.<br />

The character of the surrounding area is described as<br />

“…a well established leafy residential area. The Lots are larger than average found in Sydney,<br />

and the gardens are landscaped and well maintained. The exception to the surrounding<br />

residential dwellings is ‘The Bush School’, which is located opposite the site in Water Street”<br />

(R. Olssen for Ku-ring-gai Council, December 2006).<br />

The former John Williams Hospital site occupies land bounded by Water Street (north) and Young Street<br />

(east) and backs onto residential development in Billyard Avenue (south) and Plymouth Close (west). The<br />

original Property was once much larger, but it has been reduced in size as land was progressively sold off for<br />

residential development.<br />

The grounds have been extensively landscaped over a number of years, and include a significant arboretum<br />

with specimen trees sourced from all parts of the world. Some native canopy trees have been retained;<br />

most particularly a stand of Sydney Blue Gums (Eucalyptus saligna), and these been incorporated into the<br />

original landscape design; growing over (exotic) garden plantings and lawns. These canopy trees are located<br />

predominantly in the eastern and central parts of the Property (see Figure 1.2). Some of these Blue Gums<br />

may be remnants of the original vegetation; while others (particularly those occurring in a straight line on<br />

the Water/Young Street frontages) appear to have been planted.<br />

In order to provide for the upkeep of a large pleasure garden and latterly a Hospital, parts of the Subject<br />

Property were developed as ‘service areas’ (composting facilities, work sheds), while other areas were used<br />

to provide food for the main house and latterly the Hospital (chicken coops, vegetable gardens and a small<br />

orchard). Surviving plans and photographs show that these facilities were located in the south-western part<br />

of the Subject Property, behind the Stables – an area which has now been identified for ‘reconstruction’ to<br />

BGHF (UBM Vegetation Management Plan 2007).<br />

From 1951 to 2005, when the Property was owned by the State Government and used as a hospital and<br />

respite care centre, the grounds were generally neglected, with invasive garden plants and other weeds<br />

growing unchecked and invading the remnant BGHF along the Water Street / Young Street boundary. The<br />

understorey in this stand of BGHF trees is now wholly composed of introduced species and weeds.<br />

UBM <strong>Ecological</strong> Consultants Pty Ltd Page 13


<strong>Flora</strong> & <strong>Fauna</strong> <strong>Survey</strong> & <strong>Ecological</strong> <strong>Assessment</strong>s – 35 Water Street Wahroonga<br />

There is also some evidence that a second period of landscaping occurred in the latter part of the 20 th<br />

Century, when a number of ‘generally’ Australian native species (i.e. not indigenous to the BGHF) were<br />

planted into the Water and Young Streets remnant, in what was originally an open lawn area towards its<br />

southern end.<br />

The remnant BGHF in the Subject Property now comprises individuals and small stands of native canopy<br />

trees over a predominantly exotic/weedy understorey. These areas are hereafter described in this <strong>Ecological</strong><br />

Report as ‘BGHF Habitat’ in order to distinguish the vegetation from a viable BGHF ‘ecological community’,<br />

which is typically floristically diverse and structurally intact (see Final Determination TSC Act, Appendix 1).<br />

The closest area of ‘bushland’ to Rippon Grange is found in the grounds of ‘The Bush School’ (Wahroonga<br />

Public School), which is ~100 metres away, on the northern side of Water Street. While this remnant retains<br />

a stand of Sydney Blue Gum (Eucalyptus saligna) and some other native species, it is badly degraded with an<br />

understorey of Privets (Ligustrum spp) and other woody weeds estimated at >75% density. Flow of native<br />

genetic material (via seed dispersal) between the Bush School and the BGHF Habitat is possible, but unlikely<br />

given that there are very few sites bare soil sites where plant establishment could occur in either location.<br />

Two (2) Council reserves are located to the north-east: Turiban Reserve (@ 250 metres) and Clive Evatt<br />

Reserve (@ 425 metres) (Cumberland Ecology 2007); while other Sydney Blue Gums (Eucalyptus saligna)<br />

have been retained in private gardens (see Plates). Connectivity between these bushland reserves and<br />

through the Locality generally is retained only through the tree canopy; with both native and introduced<br />

trees providing ‘stepping stones’ through a highly urbanised environment (see Figure 4.1).<br />

2.2 Physical Environment<br />

The physical characteristics of the Subject Property and the Locality have been summarised in Table 2.3.<br />

Geology<br />

Soil Landscape Unit<br />

Local Hydrology<br />

The Subject Property is located on gently sloping land, with a moderately steep (10%)<br />

gradient from north-west to south-east – downslope towards Young Street and Billyard<br />

Avenue.<br />

Site elevation ranges from 200m AHD at the top to 176m AHD at the lower southern<br />

site boundary, sloping towards Billyard Avenue.<br />

The geology has been mapped as Ashfield Shale (Rwa), which is a unit (or substrate) of<br />

the Wianamatta Group Shales. It typically comprises black to dark-grey shale and<br />

laminite (Herbert 1983).<br />

The Subject Property is located on the Glenorie (gn) Soil Landscape Unit.<br />

Glenorie soils are erosional landscapes, comprising shallow to moderately deep red<br />

podzolic soils on crests, moderately deep red and brown podzolic soils on upper<br />

slopes, deep yellow podzolic soils on lower slopes and humic gleys, yellow podzolic<br />

soils and gleyed podzolic soils along drainage lines (Chapman & Murphy 1989).<br />

Glenorie Soil Landscape comprises undulating to rolling low hills with a local relief of<br />

50-80 m, and slopes of 5-20%. Ridges, hillcrests and valleys are narrow (Chapman &<br />

Murphy 1989).<br />

Limitations: As the gardens at Rippon Grange were developed in the late 19 th Century,<br />

and have until recently been maintained as a managed landscape, it may be assumed<br />

that the native soil profile described above has been extensively modified.<br />

The Subject Property is located with the Lovers Jump Creek sub-catchment of the<br />

Hawkesbury-Nepean Catchment (see Table 1.1). There is no external catchment inflow<br />

to the site. There are no natural drainage lines within, or in close proximity to the<br />

Subject Property. Runoff drains generally overland, to the south-east.<br />

An ephemeral man-made drainage line runs from north to south along the western<br />

side of the driveway in the south-eastern portion of the Subject Property.<br />

Existing stormwater drainage is limited to the developed areas, and consists of building<br />

roof drainage and sparsely located surface inlet pits on pavement, with discharge to<br />

Council’s stormwater system at Billyard Avenue (LHO Group, Drainage Concept Plan<br />

November 2007).<br />

2.3 Biological Environment<br />

2.3.1 Vegetation Community Mapping<br />

Native vegetation in the Sydney Basin Bioregion has been mapped by a number of authorities (Benson 1992,<br />

NPWS 2002, and Tozer et al. 2010) 7 .<br />

Over the past 10 years the former-Department of Environment Climate Change & Water (‘DECCW’) 8 has<br />

been developing vegetation maps for the greater Sydney area and the south coast of New South Wales. This<br />

is an on-going process of revision and addition as new surveys and community verification take place. Each<br />

subsequent mapping system has sought to refine the previous mapping, which has been based largely on<br />

aerial photography and physical characteristics such as geology, soil type, elevation and aspect. In the more<br />

recent mapping programs there has been an increased emphasis on ground truthing.<br />

A brief summary of these mapping programs as they relate to the native vegetation extant at 35 Water<br />

Street is presented below.<br />

2.3.1.1 National Parks & Wildlife Service 2002<br />

In 2002 the former NSW National Parks and Wildlife Service (‘NPWS’) produced a series of vegetation maps<br />

for the Cumberland Plain at the scale of 1:25 000; mapping remnants greater than 0.5 hectares in size. The<br />

NPWS mapped BGHF in part of the Subject Property, with other stands of BGHF occurring in the Locality (see<br />

Figure 2.2). The condition of the BGHF community within the Subject Property was mapped as “Txu”<br />

(canopy cover < 10% over urban development), and its conservation significance was classified as “Urban<br />

Remnant Trees (Critically Endangered Communities)”.<br />

NOTE: most urban areas which retain native canopy trees are coded ‘Txu – canopy


<strong>Flora</strong> & <strong>Fauna</strong> <strong>Survey</strong> & <strong>Ecological</strong> <strong>Assessment</strong>s – 35 Water Street Wahroonga<br />

2.3.2 Blue Gum High Forest in the Subject Property<br />

The BGHF Habitat at Water Street as mapped by Smith & Smith (2006) and adopted by the NSW Land &<br />

Environment Court (Proceedings 11193 of 2006), comprises two (2) separate stands of vegetation located in<br />

the central and eastern sectors of the site (see Figure 1.2). These two (2) areas are described as the ‘Core<br />

BGHF Habitat’.<br />

The area determined as the Core BGHF Habitat forms a reversed ‘L-shape’, running along the residential<br />

boundary on the southern side of Water Street, and extending along Young Street on the eastern boundary.<br />

This area is described in the Vegetation Management Plan (UBM 2007) as ‘Core Bushland’ and is ~20 to 35<br />

metres in width and 135 metres long along the Young Street boundary, and 15 to 40 metres wide and 125<br />

metres long near the southern boundary. The east-west length of the widest section near the southern<br />

boundary is approximately 50 metres (see Figure 1.2).<br />

The Core BGHF Habitat generally has an intact canopy of Sydney Blue Gum (Eucalyptus saligna) and other<br />

sub-canopy trees which stand over a weed infested mid-storey and groundcover strata. The mid-storey<br />

contains dense weed thickets dominated by Privets (Ligustrum spp), African Olive (Olea europaea subsp<br />

cuspidata) and Lantana (Lantana camara). The groundcover is dominated by garden escapes such as<br />

Asparagus Fern (Asparagus aethiopicus), Fishbone Fern (Nephrolepis cordifolia), Agapanthus (Agapanthus<br />

praecox), Japanese Honeysuckle (Lonicera japonica), and introduced turf grasses. However, some native<br />

resilience is indicated by the scattered occurrence of a small number of disturbance-tolerant native shrubs<br />

such as Wattles (Acacia spp), She-oak (Casuarina spp) and Sweet Pittosporum (Pittosporum undulatum).<br />

Within the Core BGHF Habitat are several small clearings which comprise areas of open lawn with scattered<br />

or few weeds extant (see Section 4.3 and Appendix 2). These open grassland areas were once managed as<br />

lawns. Some native groundcovers are present here, growing among the sparse turf. These include Wallaby<br />

Grass (Danthonia sp), Glycine, Basket Grass (Oplismenus aemulus), Weeping Meadow Grass (Microlaena<br />

stipoides), and Kidney Weed (Dichondra repens).<br />

A third area designated as ‘Non-core BGHF Habitat’ (Smith & Smith 2006) is located in the south-western<br />

sector of the Subject Property (see Figure 1.2). This part of the Property was used for more than 100 years<br />

as a service area; comprising vegetable gardens, composting and storage areas, and a chicken coup.<br />

This Non-core BGHF Habitat area retains some mature canopy trees (Sydney Blue Gums and others) growing<br />

over stone-edged garden beds containing introduced horticultural specimens (Camellia, Azalea, Clivia and<br />

Agapanthus) and bordering remnants of the former lawns. Because of its lack of native floristic diversity and<br />

structural integrity, and its long-term use as a garden and service area, this third Non-core area was not<br />

included in the original BGHF mapping by UBMC 2005 and 2006).<br />

However, this area has since been determined to be ‘potential’ BGHF based on the assumption that native<br />

seed in the soil seed bank is viable (Smith & Smith 2006), and as a result, it has been incorporated into the<br />

larger BGHF Habitat area to be rehabilitated and reconstructed (see Vegetation Management Plan UBM<br />

2007).<br />

3 FLORA ASSESSMENT<br />

3.1 Methods<br />

3.1.1 Literature Review<br />

Previous ecological studies conducted for the Subject Property and general references for the Locality and<br />

Region were searched for descriptions of similar habitats, and for recordings of flora species, populations or<br />

communities of conservation significance known to occur in the area.<br />

The main documents referenced were:<br />

• The Native Vegetation of the Cumberland Plain, Western Sydney (NPWS 2002);<br />

• Native vegetation of southeast NSW: a revised classification and map for the coast and eastern<br />

tablelands (Tozer et al. 2010);<br />

• Identity and Condition of Native Vegetation at 35 Water Street, Wahroonga (Smith, P. & Smith, J.<br />

(December 2006);<br />

• Arboricultural Impact <strong>Assessment</strong> Report for Waterbrook @ Wahroonga, 35 Water Street & 64<br />

Billyard Avenue, Wahroonga (Tree Wise Men (October 2007);<br />

• Species Impact Statement for 35 Water Street, Wahroonga (Cumberland Ecology 2007);<br />

• Vegetation Management Plan for Blue Gum High Forest Habitat 35 Water Street Wahroonga (UBMC<br />

2007);<br />

• Tree <strong>Assessment</strong> & Impact Report for a potential 5-Lot Subdivision at 35 Water Street Wahroonga<br />

(Landscape Matrix, December 2011); and<br />

• <strong>Flora</strong> <strong>Survey</strong> & <strong>Ecological</strong> <strong>Assessment</strong> for Proposed 5-Lot Subdivision at 35 Water Street Wahroonga<br />

(UBM December 2011).<br />

A number of other studies, reports and databases were reviewed and drawn upon as required, including<br />

relevant reports and mapping conducted by UBM (Chapter 9 References). Particular attention was paid to<br />

records of flora species listed under the Schedules of the Commonwealth EPBC Act and the NSW TSC Act<br />

which have previously been recorded in the Locality and Region.<br />

The current Report has been prepared as a ‘stand alone’ report. Therefore, information has been sourced<br />

from a number of previous studies and reports prepared for the Subject Property in relation to previous<br />

Development Applications. All information sourced from earlier reports has been appropriately referenced.<br />

Plant identifications were made according to nomenclature in Pellow et al. (2009) and Botanic Gardens Trust<br />

(2010). Stands of vegetation were described by their structural and floristic characteristics according to<br />

Tozer et al. (2003, 2006 and 2010).<br />

Critically Endangered and Endangered <strong>Ecological</strong> Communities were classified and named according to NSW<br />

Scientific Committee’s Final Determinations (various dates).<br />

Noxious weeds were determined using lists of weeds declared for Ku-ring-gai LGA under the NSW Noxious<br />

Weeds Act 1993 (Amended 2005).<br />

3.1.2 Field <strong>Survey</strong><br />

Field survey was undertaken by Consultant Botanist David Thomas on two (2) occasions in late May and early<br />

June 2012. A total of ~22 hours was spent actively surveying on site, with another 2-3 hours spent in<br />

laboratory time. Previous investigations by the same worker totalling 12 hours were undertaken in<br />

December 2011. Total field survey effort in the same survey locations is 34 hours.<br />

NOTE: the same worker D. Thomas who surveyed the quadrats established by Cumberland Ecology in 2007,<br />

also subsequently surveyed for UBM in December 2011 and May/June 2012.<br />

The ecological survey was undertaken in the area mapped as BGHF Habitat (per Smith & Smith 2006)<br />

generally, as well as targeting the four (4) Subject Sites proposed for future development (see Figure 1.3).<br />

Field survey was undertaken to assess the floristic composition and diversity of native species occurring<br />

within these areas. Although all parts of the Property outside the formal house gardens were surveyed in<br />

detail, the field survey focused on searching for any rare or endangered species known to occur in the<br />

Locality and Region. The presence of species known to be both ‘characteristic’ and ‘diagnostic’ of the BGHF<br />

(see Final Determination Appendix 1) was the main focus of this targeted survey.<br />

The potential impacts of the concept subdivision proposal on those areas mapped as BGHF Habitat was also<br />

assessed, and examined in the context of the adopted Vegetation Management Plan (UBM 2007).<br />

Proposed Development Areas: Native vegetation in the area proposed for development Areas 1 and 2<br />

(see Figure 1.3) was first assessed in a ‘general’ survey carried out on foot using the ‘Random Meander’<br />

method as described by Cropper (1993). This repeated the survey methodology used in the same areas<br />

during field surveys in December 2011.<br />

Using the ‘Parallel Line Method’ as described by Cropper (1993), a targeted search was undertaken for<br />

threatened species listed under the Schedules of the NSW TSC Act and/or the Commonwealth EPBC Act<br />

which have been identified as occurring, or potentially occurring, in the Locality and Region (see Table 4.1).<br />

This method involves using a series of parallel line transects within all areas identified for investigation and<br />

recording all vascular flora species located.<br />

Any noxious weeds for Ku-ring-gai (Noxious Weeds Act 1993, Revised 2005) and significant environmental<br />

weeds located were also recorded, and a visual comparison made of existing weed populations with those<br />

occurring in 2007 when the Vegetation Management Plan was prepared (UBM 2007).<br />

BGHF Habitat Areas: Following the Random Meander survey, 11 quadrats were surveyed in the BGHF<br />

Habitat Areas (see Figure 3.1 for location of quadrats). This part of the field survey included a review and<br />

reassessment of all sites surveyed by previous workers (UBMC 2006, 2007, Cumberland Ecology 2007, and<br />

UBM 2011).<br />

The locations of nine (9) of the 20 x 20 metre quadrats established by UBM (December 2011) approximately<br />

corresponded to the 10, 10 x 10 metre quadrats established by Cumberland Ecology as part of the 2007<br />

Species Impact Statement prepared for the previous owners Waterbrook (see Section 4.1 SIS).<br />

UBM <strong>Ecological</strong> Consultants Pty Ltd Page 21


<strong>Flora</strong> & <strong>Fauna</strong> <strong>Survey</strong> & <strong>Ecological</strong> <strong>Assessment</strong>s – 35 Water Street Wahroonga<br />

The proportions of exotics in each of four (4) assumed vegetation strata (i.e. tree canopy, sub-canopy, shrub,<br />

ground cover) were estimated in each quadrat. Although the quadrat size was larger than those established<br />

the 2007 and 2011 surveys, the current 2012 quadrats incorporated the location of these earlier quadrats.<br />

Each quadrat pair was located in locally uniform vegetation, except in the quadrat 7 pair where the larger<br />

quadrat included a higher proportion of indigenous vegetation.<br />

The survey results were then used to compare the health or condition of the remnant BGHF in approximately<br />

the same locations surveyed in 2006, 2007 and 2011. These results also considered the response of the<br />

vegetation to the absence of any routine maintenance since at least 2005, when the Property was sold by<br />

the NSW State government.<br />

The current health or condition, floristic diversity and structural integrity of the remnant BGHF was assessed<br />

in light of claims made by expert witnesses in the NSW Land & Environment Court hearings in 2007; i.e. that<br />

the BGHF on the Subject Property retained a high degree of resilience, and had the potential to return to a<br />

more natural condition through natural regeneration from in situ seed sources.<br />

3.1.3 Mapping and Photography<br />

The extent of the remnant BGHF has previously been mapped by a number of workers (UBM 2005, 2006,<br />

2007. Smith & Smith 2006, Cumberland 2007, and UBM 2011) and the area adopted by the NSW Land and<br />

Environment Court (Proceedings 11193 of 2006), so detailed mapping was not repeated again.<br />

Visual evidence suggests that the vegetation within the BGHF Core Habitat has not changed markedly from<br />

site conditions recorded in 2007, although there has been an increase in the distribution and density of<br />

woody weeds (particularly Privet, African Olive and Lantana), weedy ground covers and introduced vines in<br />

all areas surveyed. The extent and diversity of native understorey species has decreased concurrently.<br />

Mapping showing the location of the BGHF Habitat within the Subject Property were sourced from UBM<br />

2007 and Cumberland Ecology (2006). Similarly, vegetation mapping by NPWS (2002) and Tozer et al (2010)<br />

were sourced from the OEH website at www.environment.nsw.gov.au.<br />

The locations of the proposed new Lots within the Subject Property have been superimposed on an original<br />

drawing prepared by Tanner Architects (see Figure 1.3).<br />

3.2 Limitations to <strong>Ecological</strong> Field <strong>Survey</strong>s<br />

The diversity of flora species recorded during the current field survey is expected to be influenced by<br />

seasonal factors, with some species likely to be inconspicuous, or absent from the above-ground populations<br />

during particular times of the year. For these reasons, survey results can always be improved by extending<br />

the time allowed to provide an investigation in all seasons.<br />

However, given the long history of ecological investigations on this Property undertaken in all seasons (see<br />

Literature Review) and given that weather conditions have been favourable for plant growth for the recent<br />

spring and summer growing seasons, it is considered that the time allocated to the field surveys is more than<br />

adequate for the purposes of this Report.<br />

3.3 Field <strong>Survey</strong> Results<br />

3.3.1 Vegetation Communities<br />

Previous studies (UBMC 2005, 2006, 2007 & UBM 2011, Smith & Smith 2006, Cumberland Ecology 2007)<br />

have confirmed the remnant native vegetation within the Subject Property as BGHF. The remnant consists<br />

primarily of mature canopy trees (Sydney Blue Gum Eucalyptus saligna) considered to be ‘diagnostic’ of the<br />

BGHF, with a small number of locally indigenous shrubs and ground covers ‘characteristic’ of the CEEC also<br />

present (see Final Determination Appendix 1). While many of the native trees are likely to be remnant<br />

individuals, having been retained when the gardens were developed in the late 19 th and early 20 th Centuries,<br />

some of the younger trees have been planted since that time.<br />

The extent of the existing (and potential) BGHF on the Subject Property was determined by Smith & Smith<br />

(2006) to be 6,350 sq metres (0.635 ha). This area was subsequently adopted by the Land & Environment<br />

Court (Proceedings 11193 of 2006) and it has been used in all subsequent surveys and reports, including the<br />

current UBM flora and fauna survey.<br />

The ‘Core’ BGHF Habitat on the Subject Property is located in the eastern part of the Property, in an L-<br />

shaped distribution fronting Water and Young Streets. The understorey in dominated by woody weeds<br />

(Privets - Ligustrum spp, African Olive - Olea europaea subsp cuspidata, Lantana camara, and Cape Broom -<br />

Genista monspessulana) (see Plates).<br />

A second Core Habitat area is located towards the centre of the Property, within parts of the arboretum and<br />

landscaped gardens, although in these areas the native understorey has been totally cleared and the large<br />

trees under-planted with horticultural introductions and lawns (see Plates and Figure 1.2).<br />

3.3.2 Indigenous <strong>Flora</strong> Species<br />

A list of plant species recorded for the eight (8) transects 11 quadrats and established and surveyed in the<br />

Subject Property has been provided in Appendix 2 (transects) and Appendix 3 (quadrats) respectively.<br />

Figure 3.1 provides the location of these transects and quadrats within the Subject Property.<br />

Transect Results: For the eight (8) Transects established in the south-eastern part of the Property<br />

proposed for limited future development (i.e. Subject Sites proposed new Lots 3, 4 and 5), 170 flora species<br />

were recorded (see Appendix 2). Of these, 75% were horticultural introductions, non-indigenous native<br />

species, or weeds. See Section 3.5 for a description of the vegetation occurring.<br />

Quadrat Results: For the 11 20 x 20 metre quadrats established through the mapped BGHF Habitat Area<br />

220 flora species were recorded. Of these, 174 species (79.1%) were horticultural introductions, nonindigenous<br />

native species (i.e. planted) or weeds (see Appendix 3).<br />

Only 46 species are considered to be naturally-occurring species ‘characteristic’ of the BGHF ecological<br />

community were present (see Final Determination, Appendix1). See Section 3.4 for a description of the<br />

vegetation occurring.<br />

3.3.3 Threatened Species<br />

Twenty (20) threatened flora species have previously been recorded within a 10-km radius of the Subject<br />

Property (‘the Region’) (see Table 3.1).<br />

However, none (0) of these threatened species was located during the current (2012) or any of the previous<br />

(2005, 2006, 2007, 2011) field surveys 9 . Having been managed as an exotic garden for more than 100 years,<br />

the greater part of the Subject Property is considered not to provide suitable habitat for any of the listed<br />

species due to its long-term disturbance history, clearing and planting as an introduced garden, changes to<br />

the soil profile and composition, and the domination of the site by introduced horticultural species and<br />

weeds.<br />

3.3.4 Introduced <strong>Flora</strong> Species<br />

The vegetation in the mapped BGHF Habitat Area and in other parts of the Property is dominated by<br />

introduced species; with the majority of these having been planted as horticultural specimens at some time<br />

in the past. Many horticultural specimens popular in the 1 st half of the 20 th Century and widely used as<br />

garden plants have since naturalised in local bushland to the detriment of the native flora and fauna. Such<br />

naturalised introductions are described as ‘environmental weeds’.<br />

More introduced species than natives were recorded in the eight (8) transects (75%) and in the 11 quadrats<br />

(79.1%). The overall % cover of introduced species in the tree, shrub and ground strata was approximately<br />

75%. The introduced to indigenous ratio for each stratum was as follows:<br />

• Canopy trees - ~80%<br />

• Sub-canopy trees ~68%<br />

• Shrubs ~78%<br />

• Ground covers ~64%<br />

Thirteen (13) plants recorded are declared as ‘noxious weeds’ in the Ku-ring-gai LGA (see Table 3.2). Weeds<br />

of National Significance (‘WoNS’) present include Bridal Creeper (Asparagus asparagoides), Blackberry<br />

(Rubus fruticosus), and Lantana (Lantana camara).<br />

3.4 Description of the Vegetation in the BGHF Habitat Area<br />

The vegetation in the mapped BGHF Habitat Area (Smith & Smith 2006) mainly comprised a canopy of<br />

original Sydney Blue Gums (Eucalyptus saligna) and the occasional Rough-barked Applebox (Angophora<br />

floribunda), with numerous planted specimens also occurring (Three Wise Men, 2007). Plantings included<br />

non-indigenous or ‘generally Australian’ species, and (in the historic arboretum) many significant specimen<br />

trees from overseas. The canopy height was typically 15-30 metres.<br />

The native understorey had been cleared over 100 years previously in order to establish exotic gardens, an<br />

arboretum and extensive lawns. In some locations, soil levels were altered to construct terraces, as at the<br />

croquet lawn, stone retaining walls, grottos and pathways.<br />

The results of the 11 quadrats established within the mapped BGHF Habitat Area are presented below. See<br />

Figure 3.1 for location of the quadrats.<br />

Exotic vegetation dominated the understorey at the time of the original (2005), subsequent (2006, 2007 and<br />

2011) and current surveys (May/June 2012). The most commonly occurring environmental weeds recorded<br />

were: Large-leaved Privet (Ligustrum lucidum), Small-leaved Privet (Ligustrum sinense), Ground Asparagus<br />

(Asparagus aethiopicus var. densiflorus), Japanese Honeysuckle (Lonicera japonica), Mickey Mouse Plant<br />

(Ochna serrulata) and Morning Glory (Ipomoea indica).<br />

Locally indigenous (BGHF) species generally comprised only a small part of the vegetation (2.09%), often<br />

being limited to a few individuals within a quadrat. One (1) area in the south (sampled in quadrat 7)<br />

contained a large proportion of commonly-occurring grasses such as Weeping Meadow-Grass (Microlaena<br />

stipoides) and smaller proportions of Basket Grass (Oplismenus aemulus).<br />

Nine (9) quadrats were surveyed in similar locations to the 10 quadrats first surveyed by Consultant Botanist<br />

David Thomas for Cumberland Ecology (2007) in order to provide an opportunity to compare any change in<br />

condition of the vegetation. Quadrat 10 was located north of the original quadrat 10 of Cumberland<br />

Ecology. The extra quadrat (quadrat 11) was located in the western part of the former croquet lawn to<br />

determine whether or not the vegetation here might conform to BGHF generally (see Figure 3.1). Results<br />

from 2007 and 2012 quadrats are presented in Appendix 3.<br />

UBM <strong>Ecological</strong> Consultants Pty Ltd Page 29


<strong>Flora</strong> & <strong>Fauna</strong> <strong>Survey</strong> & <strong>Ecological</strong> <strong>Assessment</strong>s – 35 Water Street Wahroonga<br />

The total area within the quadrats surveyed was ~4,400 square metres. This represents 69.3% of the total<br />

area of BGHF mapped for the Subject Property (6,350 sq metres) by Smith & Smith (2006).<br />

The comparison of the condition of vegetation in each quadrat surveyed in 2007, 2011 and 2012 showed the<br />

vegetation contained a higher proportion of exotics in the 2012 survey (see Appendix 3). This occurred in all<br />

quadrats except the quadrat 7 pair. In this case, the larger quadrat included additional indigenous<br />

vegetation that lowered the proportion of exotics in the upper stratum and ground cover.<br />

The condition and extent of the tree canopy was substantially the same throughout the BGHF Habitat Area in<br />

each survey period (2007 vs. 2012). The trends in condition of the understorey were however significantly<br />

more towards the exotic/weed species. In the small tree stratum (i.e. sub-canopy), there was major increase<br />

in projective foliage cover (255 to 470 cover abundance units). The increase in exotic shrub and ground<br />

covers was minor (715 to 809 units for shrubs and 750 to 824 cover abundance units for ground covers) (see<br />

Table 3.3).<br />

The main increase in exotics/weeds was the result of increases in the canopy cover of Large-leaved Privet<br />

(Ligustrum lucidum); progressing it from the shrub to the small tree stratum. Ligustrum lucidum also<br />

increased its cover in the shrub stratum. The native Pittosporum undulatum increased slightly in canopy<br />

cover in the small tree and shrub stratum, also due to growth of its canopy since 2007.<br />

English Broom (Genista monspessulana) decreased in cover slightly, probably due to the increased shading<br />

by the small trees described above. Indigenous shrubs remained limited to a few scattered individuals.<br />

Regeneration comprised two (2) Bleeding Heart Trees (Homalanthus populifolius) and one (1) Rough-barked<br />

Applebox (Angophora floribunda) seedlings.<br />

In the ground cover stratum, the increase of exotics/weeds was generally small, caused mainly by the spread<br />

of Japanese Honeysuckle (Lonicera japonica), English Ivy (Hedera helix), and increases in saplings and<br />

seedlings of Small-leaved Privet (Ligustrum sinense), Camphor laurel (Cinnamomum camphora) and Mickey<br />

Mouse Bush (Ochna serrulata). These species can be expected to have a major influence on the understorey<br />

in the future as they mature to become trees and large shrubs, seed and spread further.<br />

Morning Glory (Ipomoea indica) and Wandering Jew (Tradescantia fluminensis) increased significantly in the<br />

southern section of the BGHF Habitat Area where the ground was largely bare in 2007 and affected by high<br />

nutrient levels from the former poultry run and composting area. There was no significant change in the<br />

populations of other major weeds such as Ground Asparagus (Asparagus aethiopicus var. aethiopicus var.<br />

densiflorus) and Fishbone Fern (Nephrolepis cordifolia).<br />

The native ground covers mainly comprised native grasses such as Weeping Meadow Grass (Microlaena<br />

stipoides), Basket Grass (Oplismenus aemulus), and smaller amounts of small forbs such as Common<br />

Storksbill (Geranium homeanum). These formed only a minute component of most areas as in 2007.<br />

Geranium homeanum appears to have decreased in numbers, possibly due to increased shading by small<br />

trees and smothering by exotic vines.<br />

Only one (1) large area of native ground cover occurred - in the southern section of the Property, east of the<br />

former poultry run and composting area, where the small tree and shrub strata was largely absent and the<br />

soil was unaffected by increased nutrient levels (see Figure 1.3). Weeping Meadow Grass (Microlaena<br />

stipoides) was the main ground cover here, with significant numbers of Basket Grass (Oplismenus aemulus).<br />

Sydney Blue Gum (Eucalyptus saligna) and Rough-barked Applebox (Angophora floribunda) were scattered<br />

through the area. Morning Glory Vine (Ipomoea indica) and Wandering Jew (Tradescantia fluminensis) were<br />

noted to be invading the margins of this more natural ground cover area, and can be expected to eventually<br />

cover it completely unless suitably managed.<br />

3.5 Description of the Vegetation in the Proposed Subdivision Area<br />

The current Proposal is to rezone the Subject Property Lot 1 in DP 375262 at 35 Water Street from 5(a)<br />

Special Uses (Hospital) to E4 Environmental Living. This rezoning will facilitate a future subdivision to be<br />

considered by Ku-ring-gai Council under a future development application.<br />

However, for the purposes of the current <strong>Ecological</strong> <strong>Survey</strong>, each of the four (4) proposed new Lots (i.e. one<br />

[1] new Lot in Area 1 and three [3] new Lots in Area 2) has been surveyed separately (see Figure 1.3) and the<br />

potential impacts of the future subdivision proposal have been assessed to consider any loss or impact on<br />

the BGHF Habitat.<br />

The results of the flora survey in the eight (8) transects established in Area 1 and2 are presented below.<br />

Each proposed new Lot has been subdivided into the ‘Development Zone’ – i.e. where the footprint of the<br />

new residence has been proposed; and the ‘Non-development Zone’, which is located to the rear (east) of<br />

the Lot. Figure 1.4 is a preliminary sketch used to determine the area of BGHF Habitat in Area 2 on each of<br />

potential new Lots 3, 4 and 5 which is likely to be impacted (courtesy TKD Architects).<br />

The code provided for the Condition of Vegetation assumes four (4) structural strata: tall tree (canopy), small<br />

tree, shrub and ground cover. The % of exotics is estimated for each of these and entered with a slash /<br />

between. If a stratum is absent this is shown by an “a” in the relevant place. Where there are a few<br />

individuals, but less than the 5% considered necessary to form a structural stratum, “a” might be used with<br />

the % of these species that are exotic (e.g. a-80), in the relevant place. An example would be 0/a/a-20/60.<br />

NOTE: in the descriptions provided below * indicates an introduced or non-indigenous native species.<br />

AREA 1 - POTENTIAL NEW LOT 2<br />

i) Development Zone<br />

Location: potential battle axe Lot located in south-western corner of the Property with a driveway from<br />

Water Street (see Figure 1.3)<br />

Vegetation Type: Non-bushland. Exotic garden with minor occurrences of native species: mostly planted<br />

specimens<br />

Condition of Vegetation:<br />

i) Condition north of existing building: a/100/99/99%<br />

ii)<br />

Condition south of existing building: a-100/a-100/99/70%<br />

[“a” refers to the stratum being substantially absent]<br />

Description: the area proposed as a driveway is a landscaped garden which has been overrun with weeds<br />

and horticultural escapes. In the area to the rear – proposed as a battle axe Lot - in 2006 a screening hedge<br />

of BGHF shrubs and small trees was planted along the southern and western boundary fences to provide<br />

privacy for neighbouring properties. These plantings include Sydney Blue Gum (Eucalyptus salignus);<br />

Backhousia myrtifolia; Lilly Pilli (Acmena smithii); Bleeding Heart Tree (Homalanthus populifolius); Acacia<br />

schinoides, and Blueberry Ash (Elaeocarpus reticulatus). Much of this area has now been overtaken by<br />

Morning Glory Vine* (Ipomoea indica) and other weeds.<br />

Most of southern section of proposed Lot 2 (incorporating the former chicken coop and composting areas)<br />

was maintained in the past as a mown lawn surrounded by formal garden beds, although no maintenance<br />

has taken place in the recent past. Where not overrun with introduced vines, the open grassland supports<br />

both native and exotic grasses such as Paspalum (Paspalum dilatatum*), Brome* (Bromus catharticus) and<br />

Perennial Panic Grass* (Ehrharta erecta); with the natives Weeping Meadow Grass (Microlaena stipoides)<br />

and Basket Grass (Oplismenus aemulus).<br />

Native species comprised an estimated 30% of the ground cover, depending on weed density and the<br />

amount of shade cast by the large trees. Typical ground cover species were Weeping Meadow Grass<br />

(Microlaena, Oplismenus), Cranesbill (Geranium homeanum) and Kidney Weed (Dichondra repens).<br />

No (0) threatened or otherwise significant naturally- occurring (native) flora species occurred.<br />

ii) Lot 2 Driveway from Water Street<br />

Location: western Property boundary (see Figure 1.3)<br />

Vegetation Type: Non-bushland. Exotic trees and shrubs with minor occurrences of a few native species<br />

Condition of Vegetation: a-100/90/99/99%.<br />

Description: The new driveway will extend for a distance of 4.6 metres from the existing western boundary<br />

fence, with an entry on Water Street and adjacent to the exiting main gate and carriageway. The new<br />

driveway will traverse an area of landscaped garden and will retain screening vegetation to the carriageway.<br />

Apart from a small number of Sweet Pittosporum (Pittosporum undulatum) trees, scattered occurrences of<br />

the native grass Oplismenus spp., and the planted natives at the southern end, there were no naturally<br />

occurring (native) species in the area proposed for the driveway leading to the Development Zone of Lot 2.<br />

A small clump of native Maidenhair Fern (Adiantum aethiopicum) was recorded near the entry, east of the<br />

proposed driveway. Its origin is unknown; however it is likely to have been planted owing to its location in a<br />

generally unsuitable habitat.<br />

Potential Impacts Lot 2: Lot 2 contains no areas of BGHF and will not be impacted. A number of exotic tree<br />

and shrub species will however be impacted. Appendix 4 provides details of the trees/shrubs to be removed<br />

or otherwise impacted under the Proposal (source material: Tree Wise Men October 2011).<br />

AREA 2 - POTENTIAL NEW LOT 3<br />

i) Development Zone (transect 3w – Appendix 2)<br />

Location: western section of Lot 3, as shown on Figure 1.3. In Appendix 2, the species list for this site was<br />

marked as “3w”<br />

Vegetation Type: Open (introduced) grassland with tree and shrub plantings<br />

Condition of Vegetation: estimated as: a/50/a-100/90%.<br />

UBM <strong>Ecological</strong> Consultants Pty Ltd Page 33


<strong>Flora</strong> & <strong>Fauna</strong> <strong>Survey</strong> & <strong>Ecological</strong> <strong>Assessment</strong>s – 35 Water Street Wahroonga<br />

Description: This site mainly comprised previously mown exotic and native grasses. Garden escapes and<br />

weed species were also common. Typical species were Paspalum dilatatum*, Sweet Vernal Grass<br />

(Anthoxanthum odoratum), Ribwort*(Plantago lanceolata), Cat’s Ear* (Hypochaeris radicata), Dichondra<br />

repens, Carex inversa, Hedgehog Grass (Echinopogon ovatus), and Hypericum japonicum. Microlaena<br />

stipoides was locally common adjacent to a mature Liquidambar* (Liquidambar styraciflua) which was<br />

planted in the lawn area.<br />

Old garden plantings occurred to the north of the former lawn area. These mainly comprised small trees and<br />

shrubs with under-plantings of Agapanthus* (Agapanthus praecox) and Adiantum formosum. The canopy<br />

comprised small trees such as Pittosporum undulatum, Rhododendron sp.*, Maidenhair Tree* (Gingko<br />

biloba), Cotoneaster *(Cotoneaster glauca), and Japanese Honeysuckle* (Lonicera japonica). Woody weed<br />

species, especially Camphor laurel* (Cinnamomum camphora), Privets* (Ligustrum spp.), and Mickey Mouse<br />

Bush* (Ochna serrulata) were beginning to colonise below the small tree canopy – these spreading from<br />

older plantings elsewhere in the gardens.<br />

No threatened or otherwise significant naturally occurring (native) species occurred.<br />

Condition of Vegetation: estimated to be: a/50/a-100/90%<br />

ii)Non-Development Zone (Transect 3e – see Appendix 2)<br />

Location: eastern sector of proposed Lot 3, with transect through Non-Development Zone marked as “3e”.<br />

Vegetation Type: Open (introduced) grassland with tree and shrub plantings, merging into mapped BGHF<br />

Habitat (see Figure 1.3).<br />

Condition of Vegetation: scrub to north estimated to be: a/50/a-100/90<br />

Description: A band of mostly exotic ‘scrub-type’ vegetation occurred immediately below the Development<br />

Zone, extending along the northern edge of the Lot to Young Street. Large-leaved Privet* (Ligustrum<br />

lucidum) and Pittosporum undulatum were the main small tree species; although numerous other species<br />

were also recorded (see Appendix 2.<br />

Scattered Sydney Blue Gum (Eucalyptus saligna) formed an open canopy in this part of Lot 3. One (1) small<br />

mature Rough-barked Applebox (Angophora floribunda) occurred near the fence at Young Street. The<br />

understorey was mainly exotic especially Ground Asparagus* (Asparagus aethiopicus var. densiflorus),<br />

English Ivy* (Hedera helix) and Lonicera japonica*. The indigenous vine Native Yam (Parsonsia straminea)<br />

was fairly common in the scrub and adjacent in proposed Lot 4.<br />

Below, and south of the scrub was an introduced lawn (now unmaintained) with Buffalo Grass*<br />

(Stenotaphrum secundatum), Asparagus aethiopicus*, and natives Dichondra repens, Oplismenus aemulus<br />

and Echinopogon ovatus as the main ground cover species.<br />

A small group of native species, including Pomaderris ferruginea, Sydney Golden Wattle (Acacia longifolia),<br />

Sydney Turpentine (Syncarpia glomulifera), Forest Oak (Allocasuarina torulosa), Elaeocarpus reticulatus,<br />

Acmena smithii and Sydney Rusty Gum (Angophora costata) had been planted beyond the potential<br />

UBM <strong>Ecological</strong> Consultants Pty Ltd Page 34


<strong>Flora</strong> & <strong>Fauna</strong> <strong>Survey</strong> & <strong>Ecological</strong> <strong>Assessment</strong>s – 35 Water Street Wahroonga<br />

Development Zone. Records by UBMC in 2006 noted these species as new plantings in what had been an<br />

open grassy area south of the Core BGHF Habitat area.<br />

A young Rusty Fig (Ficus rubiginosa) was observed growing as an epiphyte on a large Eucalyptus saligna at<br />

the Young Street fence. One planted tree, a Small-leaved Tuckeroo* (Cupaniopsis parvifolia), although a<br />

non-indigenous native species, was considered to be a significant planting owing to its general rarity in<br />

landscape works and relatively large size and maturity.<br />

Potential Impacts on BGHF for Lot 3: Lot 3 has 572 sq metres of BGHF, of which 77 sq metres (23 sq metres<br />

building and 54 metres driveway) or ~13.5% would potentially be affected<br />

AREA 2 – POTENTIAL NEW LOT 4<br />

i) Development Zone (Transect 4w - Appendix 2)<br />

Location: western section of potential Lot 4, as shown on Figure 1.3. In Appendix 2, the species list for this<br />

site was marked as “4w”<br />

Vegetation Type: Open (introduced) grassland with tree and shrub plantings<br />

Condition of Vegetation: estimated to be: a-100/a-90/a-90/50%<br />

Description: Lot 4 is downslope and south of potential Lot 3. It contained trees and scrub-type vegetation<br />

throughout much of the Lot; however a cleared area occurs at its western end. In common with the area<br />

potentially Lot 3, it was previously maintained as mown lawn and contained a grassy ground cover, now<br />

mainly composed of Stenotaphrum secundatum*, Anthoxanthum odoratum* and Microlaena stipoides.<br />

Exotics are rapidly colonising the area; with Plantago lanceolata*, Hypochaeris radicata* and Fireweed*<br />

(Senecio madagascariensis) occurring in the more open areas, and Ligustrum spp*, Olea europaea subsp<br />

cuspidata*, Ochna serrulata*, Hedera helix* and Asparagus aethiopicus* occurring in the more shady<br />

locations.<br />

Part of this area at the boundary with proposed Lot 3 contained a small Pittosporum undulatum 10 and a large<br />

Irish Strawberry tree* (Abutus unedo).<br />

No threatened or otherwise significant naturally-occurring (native) species occurred.<br />

Ii) Non-development Zone (Transect 4e – see Appendix 2)<br />

Location: eastern section of potential Lot 4, as shown on Figure 1.3. In Appendix 2, the species list for this<br />

site was marked “4e”.<br />

Vegetation Type: Open (introduced) grassland with tree and shrub plantings, merging into mapped BGHF<br />

Habitat area (see Figure 1.3)<br />

Condition of Vegetation: estimated to be: 0/90/90/70.<br />

10 NOTE: Pittosporum undulatum is a small native tree which seeds profusely and establishes in bushland in the absence of fire.<br />

Pittosporum is very common in the garden, and it has invaded the garden beds, paving and other structures such as the croquet lawn<br />

and former children’s play area.<br />

UBM <strong>Ecological</strong> Consultants Pty Ltd Page 35


<strong>Flora</strong> & <strong>Fauna</strong> <strong>Survey</strong> & <strong>Ecological</strong> <strong>Assessment</strong>s – 35 Water Street Wahroonga<br />

Description: Most of potential Lot 4 was identified for exclusion of development owing to the presence of<br />

several large Eucalyptus saligna. Most of the natural understorey had been removed many years previously<br />

and replaced with exotics. A few native species remained or had re-colonised, including ground covers such<br />

as Microlaena stipoides, Echinopogon spp. and Geranium homeanum.<br />

The native Pittosporum undulatum was noted to be regenerated widely and was beginning to dominate the<br />

sub-canopy to the detriment of more light-demanding native ground covers. Native understorey species<br />

occurred variably owing to the density of large trees, invading woody weeds (mainly Ligustrum lucidum*)<br />

and exotic grounds covers, mainly Asparagus aethiopicus* and Nephrolepis cordifolia*.<br />

Some native trees had also been planted in this part of potential Lot 4, including Allocasuarina torulosa and<br />

Elaeocarpus reticulatus, as well as non-locally-indigenous species including Swamp Oak* (Casuarina glauca)<br />

and White Beech*(Gmelina leichhardtii).<br />

Potential Impacts on BGHF for Lot 4: Lot 4 has 987 sq metres of BGHF, of which 96 sq metres (27 sq metres<br />

building and 69 sq metres driveway) or 9.73% would potentially be affected.<br />

AREA 2 – POTENTIAL NEW LOT 5<br />

i)Development Zone (Transect 5w – see Appendix 2)<br />

Location: western section of potential Lot 5 as shown on Figure 1.3. In Appendix 2, the species list for this<br />

site was marked as “5w”: the Non-development Zone was marked “5e”.<br />

Vegetation Type: Open (introduced) grassland with tree and shrub plantings (see Figure 1.3)<br />

Condition of Vegetation: estimated to be: 100/a/a-90/95%.<br />

Description: Trees and scrub-type vegetation occurred in the northern third of Lot 5, based on the presence<br />

of the overhanging Eucalyptus saligna canopy (Smith & Smith 2006). The potential Development Zone<br />

comprised the central and southern parts of the Lot.<br />

Much of this area contained a sealed road and car parking area at the Young Street entrance. The road area<br />

contained exotic herbaceous species and a few natives such as Euchiton sphaericum growing in cracks on the<br />

surface. The planted area north of the road (part of the former arboretum) was dominated by exotic species<br />

including a large Liquidambar styraciflua*, a mature Waterhousea floribunda*; various woody weeds such as<br />

Ligustrum spp.*, Olea europaea*, Cape Broom* (Genista monspessulana) and Cotoneaster spp*, with a<br />

mainly exotic ground cover layer. Typical ground cover species were: Asparagus aethiopicus*, Lonicera<br />

japonica*, Blowfly Grass * (Briza maxima), Fleabane* (Conyza bonariensis), and the native herb Dichondra<br />

repens.<br />

No threatened or otherwise significant naturally occurring (native) species occurred.<br />

ii)Non-development Zone (Transect 5e – see Appendix 2)<br />

Location: western section of Lot 5 as shown on Figure 1.3. In Appendix 2, the species list for this site was<br />

marked as “5e”<br />

UBM <strong>Ecological</strong> Consultants Pty Ltd Page 36


<strong>Flora</strong> & <strong>Fauna</strong> <strong>Survey</strong> & <strong>Ecological</strong> <strong>Assessment</strong>s – 35 Water Street Wahroonga<br />

Vegetation Type: Open (introduced) grassland with tree and shrub planting, merging into BGHF Habitat at<br />

the rear (east) (see Figure 1.3)<br />

Condition of Vegetation: estimated to be: a-o/80/90/90%.<br />

Description: Trees and scrub-type vegetation occurred in the northern third of Lot 5, based on the presence<br />

of Eucalyptus saligna, and determined entirely (Smith & Smith 2006) by the width or extent of the overhead<br />

tree canopy, which in places overhangs the grassland and arboretum areas.<br />

This area was similar to that in Lot 4, which it adjoined.<br />

Eucalyptus saligna was rare in this zone. Most tree species were exotic plantings, being part of the historic<br />

arboretum. These included Cedars* (Cupressus sp.), Araucaria cunninghamii* and Monterey Pine* (Pinus<br />

radiata). A few native tree species had also been planted: Blackbutt (Eucalyptus pilularis), Turpentine<br />

(Syncarpia glomulifera), and Forest Oak (Allocasuarina torulosa). Pittosporum undulatum occurred naturally<br />

in relatively small numbers; however the weedy Ligustrum lucidum was the main small tree shrub species,<br />

although at the time of the survey most were only shrub-sized.<br />

The ground cover stratum was mainly exotic, with the scrambler Asparagus aethiopicus* being the<br />

dominant. The native herb Dichondra repens was a fairly common species, and numerous other species<br />

occurred in low proportions including: Hypochaeris radicata*, Lonicera japonica*, Climbing Asparagus*<br />

(Asparagus plumosus), Ribwort* (Plantago lanceolata), Agapanthus sp.*, and the natives Microlaena<br />

stipoides and Senecio hispidulus.<br />

Potential Impacts on BGHF for Lot 5: Lot 5 has 353 sq metres of BGHF, of which none would be affected.<br />

Development on Lots 3 and 4 will potentially have some impact on the Blue Gum High Forest. The<br />

approximate area of mapped Blue Gum High Forest in the Subject Lots and the area potentially to be<br />

impacted by development has been summarised in Table 4.3 (Source: Landscape Matrix report 13 December<br />

2011).<br />

3.6 <strong>Assessment</strong>s of Significance – <strong>Flora</strong><br />

<strong>Assessment</strong>s which consider the potential direct and indirect impacts of a possible futuresubdivision on the<br />

BGHF have been prepared for each of the possible Subject Sites in Area 2, potential Lots 3, 4 and 5. Potential<br />

Lot 2 in Area 1 is located outside the mapped BGHF area (UBM 2007) and therefore no <strong>Assessment</strong> of<br />

Impacts has been prepared.<br />

3.6.1 Commonwealth Legislative Considerations for the Critically Endangered <strong>Ecological</strong><br />

Community ‘Blue Gum High Forest’<br />

An <strong>Assessment</strong> of Significance is not required for this patch of remnant vegetation as it does not meet the<br />

condition criteria as set out in the listing advice for Blue Gum High Forest in the Sydney Basin Bioregion - a<br />

‘critically endangered ecological community’ under this Act. Specifically, the listing Condition Threshold<br />

requiring remnant patches to be more than one (1) ha in size or adjacent to a remnant more than one (1) ha<br />

in size is not met.<br />

3.6.2 NSW Legislative Considerations for the Critically Endangered <strong>Ecological</strong> Community Blue<br />

Gum High Forest<br />

A Seven-part Test of Significance under Section 5A of the Environmental Planning and <strong>Assessment</strong> Act 1979<br />

is designed to determine "whether there is likely to be a significant effect on threatened species,<br />

populations, ecological communities or their habitats" (as listed on the Schedules of the NSW TSC Act), and<br />

consequently, to determine whether a Species Impact Statement is required.<br />

Each of the Subject Sites potential new Lots 3, 4 and 5 are part of the 19 th Century arboretum established by<br />

the first landowner. Individual plantings and remnant trees with a highly degraded understorey also occur<br />

throughout the Subject Property, including numerous Sydney Blue Gums (Eucalyptus saligna), which have<br />

been retained over lawns and exotic gardens.<br />

A small number of understorey species (grasses and flowering forbs) characteristic of the BGHF also occur in<br />

those areas not overrun with horticultural escapes and weeds. These species generally occur in areas<br />

otherwise devoid of other native vegetation, and are generally found to be regenerating in areas formerly<br />

maintained as lawns or garden beds (see species recorded in potential new Lots 3, 4 and 5 in Appendix 3).<br />

Despite being characteristic of the BGHF ecological community, the understory species occurring are<br />

common to a number of other vegetation communities in the Locality and Region; with only some of these<br />

communities being listed as ‘endangered’.<br />

Even so, in accordance with the precautionary principle the following Seven-part Test has been undertaken<br />

to assess the impacts of the proposed subdivision on BGHF in potential new Lots 3, 4 and 5. A total of 173 sq<br />

metres (0.0173 ha) of BGHF out of a total area of 6,350 sq metres (0.635 ha) in the Subject Property is likely<br />

to be impacted in the proposed Lots 3 and 4. No BGHF will be impacted on Lot 5. A total of 11 BGHF trees<br />

will be removed or otherwise impacted on Lots 2, 3 and 4. Nine (9) BGHF trees will be removed from the<br />

mapped BGHF area in Lots 3 and 4.<br />

This Seven-part Test relates to the possible subdivision of land within the larger Subject Property to<br />

potentially create up to five (5) residential allotments. Potential allotments Lots 3, 4 and 5, retain trees<br />

UBM <strong>Ecological</strong> Consultants Pty Ltd Page 39


<strong>Flora</strong> & <strong>Fauna</strong> <strong>Survey</strong> & <strong>Ecological</strong> <strong>Assessment</strong>s – 35 Water Street Wahroonga<br />

characteristic of the BGHF (Figure 1.2), with a small number of understorey species also present. While<br />

some of these trees are ‘characteristic’ of the BGHF community, only Sydney Blue Gum (Eucalyptus saligna)<br />

is considered to be ‘diagnostic’ for the community (see Definitions and Abbreviations for definitions of<br />

‘characteristic’ and ‘diagnostic’).<br />

Although two (2) Pittosporum undulatum (found in BGHF and many other communities) may be impacted in<br />

Lots 2, this area is clearly outside the area mapped as BGHF and accepted by the NSW Land & Environment<br />

Court (Proceedings 1113 of 2006). Accordingly no <strong>Assessment</strong> under the legislation has been required.<br />

This <strong>Assessment</strong> of Significance has considered the potential impacts of development; including future land<br />

uses on the proposed new Lots, construction impacts and the installation of services and it has also<br />

considered the potential for edge effects. This <strong>Assessment</strong> also considers the OEH/Council approved<br />

Vegetation Management Plan (UBM 2007) prepared for the BGHF Habitat on the Subject Property which will<br />

be implemented by the Proponent, most likely under a Memorandum of Understanding.<br />

Seven-part Test for BGHF on proposed Lots 3 & 4 (see Figure 1.3)<br />

(a) …in the case of a threatened species, whether the action proposed is likely to have an adverse effect on<br />

the life cycle of the species such that a viable local population of the species is likely to be placed at risk of<br />

extinction,<br />

Blue Gum High Forest (“BGHF’) is not a threatened species, but occurs as a critically endangered<br />

ecological community; therefore this item is not applicable.<br />

(b) …in the case of an endangered population, whether the action proposed is likely to have an adverse effect<br />

on the life cycle of the species that constitutes the endangered population such that a viable local population<br />

of the species is likely to be placed at risk of extinction,<br />

Blue Gum High Forest (“BGHF’) is not an endangered population, but occurs as a critically<br />

endangered ecological community; therefore this item is not applicable.<br />

(c) …in the case of an endangered ecological community or critically endangered ecological community,<br />

whether the action proposed:<br />

(i) is likely to have an adverse effect on the extent of the ecological community such that its local<br />

occurrence is likely to be placed at risk of extinction, or<br />

The vegetation in the Subject Sites potential new Lots 3 and 4 (Area 2 – see Figure 1.3) contain some<br />

native species consistent with the description of BGHF set out in the Final Determination of this<br />

community (see Appendices 1 and 2). The BGHF community here is represented mainly by remnant<br />

Sydney Blue Gums (Eucalyptus saligna) – however because the understorey comprises >75%<br />

introduced species or weeds, the vegetation within the Subject Sites is not considered to represent a<br />

structurally intact, interactive and viable native ecological community. This is due to the remnant’s<br />

small size, isolation from other bushland areas, very low number and low % cover of locally<br />

indigenous flora species (~25%), chronically degraded nature of the understorey (~75%)as the result<br />

of invasion by garden escapes and weeds, and its long-standing land use and disturbance history.<br />

UBM <strong>Ecological</strong> Consultants Pty Ltd Page 40


<strong>Flora</strong> & <strong>Fauna</strong> <strong>Survey</strong> & <strong>Ecological</strong> <strong>Assessment</strong>s – 35 Water Street Wahroonga<br />

The larger part of both potential new Lots 3 and 4 in Area 2 comprises an introduced grassland<br />

habitat with scattered remnant and planted canopy trees, some large shrubs, and a small number of<br />

native ground covers. The lawns have not been maintained in recent years, and are rapidly being<br />

overtaken by woody weeds.<br />

The area of remnant vegetation likely to be impacted by the proposed subdivision is very small -173<br />

sq metres or 2.74% of the total mapped BGHF area -highly simplified and dominated by woody weed<br />

and other introduced species (as above). Although it adjoins a larger area of BGHF Habitat in the<br />

eastern part of the Subject Property, this adjoining Habitat is chronically degraded and no longer<br />

functions as a viable interactive native ecological community.<br />

Degradation of good quality bushland at the suburban: bushland interface often results from<br />

inappropriate recreational activities, plantings and encroachments for gardens, storage or vehicle<br />

parking or access, disposal of lawn clippings and garden debris, as well as overzealous underscrubbing<br />

or clearing for bushfire hazard purposes – these being collectively described as ‘edge<br />

effects’. In Area 2, no such negative impacts are likely to occur because the understorey in the<br />

adjacent BGHF Core Habitat is already chronically degraded, with only remnant canopy and some<br />

sub-canopy trees remaining in situ.<br />

Further, although some connectivity through the local area is retained through the tree canopy, 11<br />

BGHF trees are proposed to be removed or otherwise impacted under the Proposal; and of these,<br />

two (2P individuals are the small native tree Pittosporum undulatum , which is known to be invasive<br />

in numerous bushland communities in the long-term absence of fire. It is however possible that the<br />

concept development footprint can be amended to avoid removing any BGHF trees. This option is<br />

currently being considered.<br />

The closest stand of BGHF is located in Wahroonga Public School (‘the Bush School’), on Water Street<br />

a short distance to the north-east. The modification of 173 sq metres of BGHF in Lots 3 and 4 out of<br />

a total area of 6,350 sq metres being (2.74%) is not likely to reduce this connectivity.<br />

Gene flow (via seed dispersal) between the two (2) BGHF sites is possible but unlikely, as there very<br />

few establishment sites available in either location; the understorey having been colonised by<br />

introduced and weed species. Therfore no effect on the extent of the BGHF in the larger Subject<br />

Property, Locality or Region is expected if the Proposal is allowed to proceed.<br />

(ii) is likely to substantially and adversely modify the composition of the ecological community such that<br />

its local occurrence is likely to be placed at risk of extinction,<br />

The vegetation in the Subject Sites potential new Lots 3 and 4 (Area 2) contain some native species<br />

consistent with BGHF (primarily mature Sydney Blue Gums (E. saligna),; however is not considered to<br />

represent a viable vegetation community for all of the reasons listed above in item C(i).<br />

The larger part of both proposed Lots 3 and 4 comprises a grassland habitat with scattered remnant<br />

and planted canopy trees, some large shrubs, and a small number of native ground covers. The<br />

lawns have not been maintained in recent years, and are rapidly being overtaken by woody weeds.<br />

On balance, only about 25% of the flora species recorded comprise local native species, and of these,<br />

UBM <strong>Ecological</strong> Consultants Pty Ltd Page 41


<strong>Flora</strong> & <strong>Fauna</strong> <strong>Survey</strong> & <strong>Ecological</strong> <strong>Assessment</strong>s – 35 Water Street Wahroonga<br />

most are species which commonly occur in a number of different plant communities in the Sydney<br />

Bioregion.<br />

Eleven (11) BGHF trees are likely to be removed or otherwise impacted if the identified potential<br />

subdivision proceeds (8 in potential Lot 3 and 4 in potential Lot 4) 11 , with two (2) of these being the<br />

widespread Pittosporum undulatum. If the development footprint cannot be modified to avoid<br />

damage to these BGHF trees, their removal will not impact unduly on the composition of the BGHF<br />

Habitat in the Subject Sites potential Lots 3 and 4.<br />

This Report has recommended the retention and rehabilitation of those parts of potential new Lots 3<br />

and 4 not required for development (i.e. areas adjoining the ‘core’ BGHF Habitat to the east). If this<br />

recommendation is adopted, the Proposal will result in a significant improvement in the condition of<br />

the BGHF and provide a net gain.<br />

Minimal modification of the existing BGHF Habitat is expected to result from this Proposal but it is<br />

highly unlikely that the removal of 173 sq metres of simplified and modified BGHF from a total area<br />

of 6,350 sq metres (2.74%) will place the community at risk of local extinction.<br />

(d) …in relation to the habitat of a threatened species, population or ecological community:<br />

(i) the extent to which habitat is likely to be removed or modified as a result of the action proposed, and<br />

The vegetation in the Subject Sites proposed Lots 3 and 4 retain some native species consistent with<br />

BGHF (primarily mature Sydney Blue Gums (E. saligna), however it is not considered to represent a<br />

viable vegetation community due to the reasons listed above in Item C(i).<br />

The larger part of both potential new Lots 3 and 4 comprises an introduced grassland habitat (former<br />

lawns) with scattered remnant and planted canopy trees, some large shrubs, and a small number of<br />

native ground covers. The lawns have not been maintained in recent years, and are rapidly being<br />

overtaken by woody weeds<br />

About 173 sq metres of simplified and modified BGHF will be impacted under the potential<br />

subdivisionl, being some 2.74% of the total area of BGHF in the Subject Property. Eleven (11) BGHF<br />

trees are likely to be removed or otherwise impacted under the Proposal (6.5 trees in Lot 3 and 2.5<br />

in Lot 4 12 ). If the development footprint cannot be modified to avoid damage to these BGHF trees,<br />

their removal will not impact unduly on the composition of the BGHF Habitat in the Subject Property.<br />

This Report has recommended the retention and rehabilitation of those parts of potential new Lots 3<br />

and 4 not required for development (i.e. areas adjoining the ‘core’ BGHF Habitat to the east). If this<br />

recommendation is adopted the Proposal will result in a significant improvement in the condition of<br />

the extant BGHF, and result in a net gain for the ecological community overall.<br />

(ii) whether an area of habitat is likely to become fragmented or isolated from other areas of habitat as<br />

a result of the proposed action, and<br />

11 One (1) Pittosporum undulatum may be impacted in Lot 2, however as this area is not within the mapped BGHF area,<br />

<strong>Flora</strong> & <strong>Fauna</strong> <strong>Survey</strong> & <strong>Ecological</strong> <strong>Assessment</strong>s – 35 Water Street Wahroonga<br />

The 173 sq metres of BGHF Habitat to be removed or otherwise impacted under the Proposal is<br />

located in the rear or eastern sectors of proposed Lots 3 and 4 where the Lots adjoin a much larger<br />

area of ‘Core’ BGHF Habitat along the eastern property boundary. This area is located outside the<br />

potential Development Zone (e.g. house footprints and shared driveway). The BGHF Habitat areas<br />

within the proposed new Lots are proposed as Non-Development Zones. It is likely that these areas<br />

will not be developed under the potential subdivision and as such, they will not be isolated from the<br />

‘Core’ Habitat area.<br />

The closest stand of remnant BGHF is located in the grounds of the Wahroonga Public School (‘The<br />

Bush School’) on the northern side of Water Street. Under the Proposal, the extant area of BGHF on<br />

the Subject Property will not be fragmented or otherwise isolated from other bushland areas. Gene<br />

flow between the two (2) BGHF sites is possible, but not likely given the chronically degraded nature<br />

of the understorey vegetation in both sites, where introduced species and weeds dominant in the<br />

ground cover, thereby excluding suitable establishmen sites.<br />

(iii) the importance of the habitat to be removed, modified, fragmented or isolated to the long-term<br />

survival of the species, population or ecological community in the locality,<br />

Potential new Lots 3 and 4 are located in the south-eastern part of the Subject Property, and with<br />

the exception of potential new Lot 5, they adjoin an area mapped as ‘Core’ BGHF Habitat. The<br />

adjoining area of ‘Core’ Habitat is chronically degraded and comprises stands of remnant Sydney<br />

Blue Gums (E. saligna), and a small number of other trees growing over an understorey composed<br />

almost entirely of woody weeds, scrambling ground covers and introduced vines.<br />

The BGHF in the adjoining Subject Sites potential new Lots 3 and 4 (an area of ~1,559 sq metres) is in<br />

better conditions towards their western ends, being mainly introduced lawns with remnant and<br />

planted canopy trees and large shrubs (part of the former arboretum). The lawns have not been<br />

maintained in recent years, and they are rapidly being colonised by woody weeds (Privets, African<br />

Olive, Broom and Lantana) and ground covers (Asparagus spp, and Fishbone Fern). The weed<br />

species listed above occur widely, and dominate the understorey towardsthe potential Lot’s eastern<br />

ends where they adjoin the Core BGHF Habitat Area along the eastern boundary.<br />

The native ground covers (grasses and some flowering forbs) recorded in the western parts of<br />

potential new Lots 3 and 4 occur in the more open lawn areas and along footpaths where light levels<br />

are higher. However, these native understorey storey species occur in very low numbers and in a<br />

scattered distribution. Further, the species recorded, although ‘characteristic’ species of BGHF they<br />

are all commonly-occurring species in other ecological communities and occur widely in the Locality<br />

and Region. None of these understorey species is considered to be ‘diagnostic’ for BGHF.<br />

The BGHF Habitat to be removed or otherwise impacted under the potential subdivision is minimal<br />

given that it represents only 2.74% of the total area of BGHF in the Subject Property, a considerable<br />

reduction to the approved Hospital development.<br />

Further, the vegetation within the Subject Sites potential Lots 3, 4 and 5 is not considered to<br />

represent a viable ecological community in its present condition. The long-term survival of the BGHF<br />

ecological community within the Subject Property is highly unlikely to be compromised by the<br />

UBM <strong>Ecological</strong> Consultants Pty Ltd Page 43


<strong>Flora</strong> & <strong>Fauna</strong> <strong>Survey</strong> & <strong>Ecological</strong> <strong>Assessment</strong>s – 35 Water Street Wahroonga<br />

removal of 173 sq metres of simplified and modified BGHF in potential new Lots 3 and 4. Given that<br />

6,177 sq metres of BGHF Habitat will be retained, rehabilitated and managed in perpetuity,<br />

opportunities exist for a net gain of good quality BGHF in the local area.<br />

Therefore it is considered that the potential subdivision that could occur if the Planning Proposal<br />

proceeds will not significantly modify any stands of remnant BGHF so that it further fragments,<br />

isolates or removes habitat for any listed species or populations.<br />

(e) …whether the action proposed is likely to have an adverse effect on critical habitat (either directly or<br />

indirectly),<br />

Critical habitat has not been identified for BGHF.<br />

(f) …whether the action proposed is consistent with the objectives or actions of a recovery plan or threat<br />

abatement plan,<br />

A formal recovery plan has not been developed for BGHF; therefore the Proposal does not conflict<br />

with the objectives of actions of any recovery plan or threat abatement plan for BGHF.<br />

(g)… whether the action proposed constitutes or is part of a key threatening process or is likely to result in the<br />

operation of, or increase the impact of, a key threatening process.<br />

Within the Subject Sites potential new Lots 3 and 4, the Proposal is not expected to result in any<br />

action that is part of a Key Threatening Process. Key Threatening Processes are relevant in relation<br />

to species, populations or vegetation communities listed under the TSC Act.<br />

The KTP ‘clearing of native vegetation’ will apply as a small number of BGHF trees in the<br />

Development Zone of each Lot will be removed. Several small areas of native understorey<br />

vegetation (commonly occurring grasses and forbs) will also be cleared to facilitate development.<br />

The possibility of invasion by woody weeds, exotic vines and perennial grasses is also not applicable<br />

in this case as all of these elements are already present on site, on large numbers.<br />

No flora species, populations or other ecological communities listed under the TSC Act occur within<br />

the larger Subject Property, Subject Sites or their immediate environs.<br />

Therefore, having given consideration to Section 5(a) of the NSW Environmental Planning and <strong>Assessment</strong><br />

Act 1979, it is concluded that a potential future residential subdivision of the Subject Property in the<br />

manner envisaged in the subdivision concept plan accompanying the Planning Proposal WOULD NOT<br />

require the preparation of a second Species Impact Statement for the CEEC Blue Gum High Forest in the<br />

Sydney Basin Bioregion.<br />

4 FAUNA ASSESSMSENT<br />

4.1 Overview<br />

The Subject Property at #35 Water Street is located in the developed residential suburb of Wahroonga. The<br />

grounds have been extensively landscaped over a number of years, and include a significant arboretum with<br />

specimen trees sourced from all parts of the world. Some native canopy trees have been retained; most<br />

particularly a stand of Sydney Blue Gums (Eucalyptus saligna), and these been incorporated into the original<br />

landscape design; growing over (exotic) garden plantings and lawns. These canopy trees are located<br />

predominantly in the eastern and central parts of the Property (see Figure 1.2).<br />

In order to assess the likelihood of native fauna species utilising the trees and gardens at 35 Water Street a<br />

diurnal and nocturnal fauna survey was undertaken. Any species listed as threatened under the NSW TSC<br />

Act and/or the Commonwealth EPBC Act 1999 (see Table 4.4) were targeted during the survey.<br />

4.2 <strong>Fauna</strong> Methods<br />

The diurnal fauna survey was undertaken by Ecologist Rebecca Carman (BSc, MPhil, PGDipWldMgt) on 29 th May and 7 th<br />

June 2012. The surveys conducted on each occasion are outlined in Table 4.1.<br />

Habitat assessment, active searches and<br />

opportunistic observations<br />

Spotlighting and ultrasonic call recording,<br />

The fauna field survey was aimed at assessing the species richness of the site; to investigate the range of<br />

fauna habitats present, and to determine the potential for local threatened fauna species to occur.<br />

The fauna survey incorporated a range of techniques designed to target species from all fauna groups that<br />

would be expected to occur on the site, including birds, mammals and reptiles. These techniques included a<br />

series of diurnal bird censuses, searches for active herpetofauna (reptiles), and recording of indirect<br />

evidence of fauna presence (e.g. tracks, scats, hollows, nests, diggings, bones and other traces). In addition,<br />

all opportunistic sightings of fauna were recorded.<br />

All relevant previous reports and databases were reviewed and drawn upon (see Reference list for previous<br />

studies and reports). Particular attention was paid to records of species listed under the Schedules of the<br />

EPBC or TSC Acts known to occur in the Locality and Region.<br />

Field surveys were restricted to the land that comprised the residential allotment at #35 Water Street,<br />

although observations of fauna utilising neighbouring properties (manly birds) were also made. While<br />

UBM <strong>Ecological</strong> Consultants Pty Ltd Page 45


<strong>Flora</strong> & <strong>Fauna</strong> <strong>Survey</strong> & <strong>Ecological</strong> <strong>Assessment</strong>s – 35 Water Street Wahroonga<br />

surveying this area, the condition and structure of any fauna habitats present were identified, and a<br />

consideration of their potential to support locally-occurring populations of threatened fauna was<br />

determined.<br />

Species specific survey methods are set out below.<br />

Diurnal Birds<br />

Formal bird point censuses were conducted in three (3) locations within the Subject Property, one towards<br />

the front, one in the centre, and the other towards the back of the Property. The formal census involved<br />

‘point bird counts’ at these locations. This method was used in addition to the opportunistic bird census<br />

conducted over the remaining areas of the Subject Property. Birds were identified on the basis of visual<br />

identification and by their characteristic calls. All opportunistic observations of bird species were recorded<br />

while undertaking general field survey activities.<br />

Herpetofauna Census<br />

Reptiles and amphibians were surveyed using hand-searches around the Subject Property. Searches<br />

concentrated on areas containing woody debris or urban refuse, those on and around rock terraces and<br />

around the base of trees; and this included techniques such as carefully turning over rocks, logs or garden<br />

furniture wherever these were encountered. These were replaced on site after inspection. All opportunistic<br />

sightings were noted.<br />

Bats<br />

Two (2) stationary ultrasonic bat call detectors (AnaBat SD1, Titley Electronics) were used to record bat calls<br />

throughout the Subject Property. The units were positioned where predicted ‘fly-ways’ exist and left in<br />

position for 4.5 hours from dusk on 7 th June.<br />

In relation to the analysis of those microchiropteran bat calls obtained, it is noted that some insectivorous<br />

bat species have distinctive echolocation calls that are unlikely to be confused with those of other species.<br />

Other bats species overlap in both call frequency and structure, making identification problematic in some<br />

cases. The degree of confidence or reliability associated with call identifications will depend on the quality<br />

of the recordings as well as the activity of the bat at the time of recording and flight direction. In some<br />

instances, a particular species may be identified with confidence, while at other times its identification will<br />

be less certain.<br />

Nocturnal fauna<br />

Spotlighting was undertaken for all terrestrial and arboreal mammals and for nocturnal birds using a<br />

Lightforce 100 Watt hand-held spotlight with a red filter to minimise impacts on nocturnal species. The<br />

spotlighting session was carried out during and after dusk for one (1) hour along existing pathways to<br />

minimise disturbance by the observer.<br />

UBM <strong>Ecological</strong> Consultants Pty Ltd Page 46


<strong>Flora</strong> & <strong>Fauna</strong> <strong>Survey</strong> & <strong>Ecological</strong> <strong>Assessment</strong>s – 35 Water Street Wahroonga<br />

Searches for Evidence of Species Presence<br />

Searches were conducted for animal scats of both predatory and non-predatory species. Where these were<br />

encountered, scats were identified on site; first to genus and then to species level, wherever possible. The<br />

search concentrated on the ground area beneath trees, in garden beds and edge sites, as well as amongst<br />

leaf litter and on the open lawns.<br />

Searches were also made for other characteristic signs of fauna species’ presence; including tracks, bones,<br />

hair, shed skins and animal remains, as well as nests, diggings, burrows, chew marks, scratchings and pellets<br />

(indicative of birds of prey).<br />

4.3 Limitations to <strong>Fauna</strong> Field <strong>Survey</strong>s<br />

The diversity of the species recorded during the current field surveys is expected to be influenced by seasonal<br />

factors, with some species likely to be inconspicuous, or absent from the above-ground populations during<br />

particular times of the year. For these reasons, survey results can always be improved by extending the time<br />

allowed to provide an investigation in all seasons.<br />

The cooler autumn/winter months are acknowledged not to be ideal for fauna surveys, and as such, climatic<br />

conditions at the time of survey (May/June) are recognised as a limitation. Unfortunately this could not be<br />

avoided. However, UBM has assembled a list of all previous fauna surveys from previous studies and reports<br />

(see Appendix 4) to provide a point of comparison. The potential for each of these species to occur, or<br />

potentially occur in the Subject Property given favourable seasonal conditions has also been assessed.<br />

The list of fauna species recorded by the current field surveys should not be regarded as being fully<br />

comprehensive, but rather only as providing an indication of the species present at the time of the survey<br />

(May/June 2012). <strong>Survey</strong>s carried across all seasons over a period of several years are needed to identify all<br />

of the species present in an area, especially as some species are only present at certain times of the year (e.g.<br />

migratory birds), while others may require specific weather patterns and seasonal conditions for optimum<br />

levels of detection, e.g. amphibians.<br />

On establishing the suite of resident native species occurring or potentially occurring in an area by utilising<br />

the habitat requirements and associations of these animals, the diversity of other native species that could<br />

occur on occasion can be determined. For example, if a hollow-associated owl is detected, then there is the<br />

potential that, if previously recorded in the vicinity of the Study Area, other species of owls with similar<br />

nesting requirements may also be present. By using those species recorded to predict the full range of fauna<br />

potentially present in the Study Area helps to overcome some of the limitations associated with seasonal<br />

constraints and of surveys of limited duration.<br />

In this study UBM has considered all fauna species detected during previous studies that may not be present<br />

or detected during the current field investigations (Appendix 4). Given the long history of fauna survey on<br />

this Property, dating from 2005 and repeated in 2006 and 2007, surveys have been carried out in all seasons<br />

in accordance with the Guidelines for threatened species assessment (DECC 2007).<br />

4.4 <strong>Survey</strong> Results<br />

4.4.1 <strong>Fauna</strong> Species Recorded<br />

Previous fauna surveys and compilation lists from OEH databases have identified 55 mammals, 186 birds, 47<br />

native reptiles, and 18 native frogs for the Region (i.e. within a 10 x 10 km area centred on the Subject<br />

Property). Of those native species previously recorded in the Region, 31 are listed as ‘vulnerable’,<br />

‘endangered’, ‘critically endangered’ and/or ‘migratory’ under the Schedules of the EPBC and/or TSC Acts<br />

(see Table 3.2).<br />

By the completion of the current field survey (May/June 2012), eight (8) bird species were detected within,<br />

adjacent to, or flying over the Subject Property; the latter identified by their distinctive calls as well as<br />

observation (Table 4.2). The Powerful Owl (Ninox strenua) is listed as ‘vulnerable’ under the TSC Act and was<br />

heard calling from outside the Subject Property during nocturnal surveys.<br />

Two (2) native mammalian species were observed on the Subject Property; the Common Ringtail Possum<br />

(Pseudocheirus peregrines) and Swamp wallaby (Wallabia bicolour).<br />

No (0) calls were recorded by either of the ultrasonic bat call detectors.<br />

4.4.2 <strong>Fauna</strong> Habitat <strong>Assessment</strong><br />

Habitat types<br />

Modified environment: Comprises approximately half of the Subject Property and includes the buildings,<br />

driveways, footpaths, garden beds, cleared land, retaining walls and other built structures. The vegetation<br />

comprises a range of introduced landscape and horticultural species. The majority of these species have<br />

been planted over a period of many years, although there are a few remnant native species present.<br />

Previous arborist reports (Tree Wise Men 2007, 2011 and Landscape Matrix 2011) and observations in the<br />

field have indentified that only one (1) exotic tree in the modified environment is hollow bearing (this being<br />

a Liquidambar styraciflua).<br />

An ephemeral man-made drainage line runs along the western side of the driveway in the south-eastern<br />

section of the Subject Property. It is in poor condition and not considered to provide valuable resources to<br />

any native species.<br />

The native species supported by this habitat type are the typical urban-tolerant fauna species and the<br />

Subject Property provides no unique habitat essential to the survival of any of these species.<br />

Eucalypt Woodland: Occurs mainly within the eastern and southern section of the Subject Property. The<br />

canopy consists of mature eucalypt species while the understory is a mixture of native and exotic shrubs and<br />

groundcovers. Seven (7) native and one (1) exotic hollow bearing trees are present that are suitable for<br />

smaller hollow-dependant native animals.<br />

Wildlife Corridors and Vegetation Links<br />

Reviews of aerial photographs of the Region have identified areas of nearby bushland. The following areas<br />

(and their approximate distance from the Subject Property) have been identified (see Figure 4.1):<br />

Wahroonga Public School (100 metres north) – highly modified Blue Gum High Forest<br />

Turiban Reserve (250 metres north-east)<br />

Clive Evatt Reserve (440 metres north-east)<br />

Lovers Jump Creek (1 km east)<br />

Ku-ring-gai Chase National Park (>1 km north)<br />

The connectivity to these other areas of bushland is limited, with the exception of scattered native canopy<br />

species existing on nearby streets and in residential properties. The urban-tolerant species detected on the<br />

Subject Property are likely to have no difficulty traversing through these urban environments via the tree<br />

canopy, although this is discontinuous. The majority of the species detected within any large areas of<br />

bushland would not travel through urban environments to utilise the resources of the Subject Property.<br />

4.4.3 Threatened <strong>Fauna</strong> <strong>Assessment</strong><br />

Table 4.4 assesses the likelihood of threatened fauna species (previously recorded, and/or thought to<br />

potentially occur within the Study Region, being present, or utilizing, the Subject Property. A description of<br />

the likelihood of occurrence is given in Table 4.3. It also considers any potential impacts the Proposal may<br />

have on the said threatened species.<br />

Although only (1) threatened fauna species – the Powerful Owl (Ninox strenua) - was detected during the<br />

current field investigations, there are suitable resources available within the Subject Property to support a<br />

number of other threatened species. Accordingly, <strong>Assessment</strong>s of Significance (commonly called the ‘Sevenpart<br />

Test’) have been prepared (see Section 4.5) for those species most likely to occur, being:<br />

• Powerful Owl (Ninox strenua)<br />

• Grey-headed Flying-fox (Pteropus poliocephalus)<br />

• Gang-gang Cockatoo (Callocephalon fimbriatum)<br />

4.5 <strong>Assessment</strong>s of Significance - <strong>Fauna</strong><br />

A previous report, the Species Impact Statement (Cumberland Ecology 2007) prepared in support of the<br />

earlier Hospital Proposal conducted <strong>Assessment</strong>s of Significance under Part 5(a) of the NSW EP&A Act 1979<br />

(commonly called the Seven-part test) for a number of fauna species; being those species listed in the NSW<br />

Atlas of Wildlife as having been recorded within a 10-km radius of the Subject Property, regardless of where<br />

they occurred on the Subject Property or not. Those species were:<br />

Superb Fruit-dove<br />

Glossy Black cockatoo<br />

Gang-gang cockatoo<br />

Masked Owl<br />

Powerful Owl<br />

Barking Owl<br />

Large-eared Pied Bat<br />

Eastern Bentwing-bat<br />

Yellow-bellied Sheathtail Bat<br />

Eastern Free-tail bat<br />

Grey-headed Flying-fox<br />

Each of the Seven-part Tests carried out concluded that the former Hospital Proposal, which would have<br />

removed ~4.9% of the total area of BGHF Habitat on the Subject Property, was NOT LIKELY to impact on the<br />

habitats or life cycles any of these species.<br />

The Planning Proposal and potential future subdivision, as envisaged on the concept plan accompanying the<br />

Planning Proposal, would remove only 173 sq metres or 2.74% of the BGHF Habitat on the Subject Property<br />

(@ 0.635 ha) and therefore have a significantly reduced impact on the habitat of any of the above-listed (if at<br />

all). Specific habitat requirements for each of these species are outlined in Table 4.4.<br />

However, under the precautionary principle, Seven-part Tests have been undertaken and updated for the<br />

following species; being those species actually recorded on site during field investigations carried out<br />

between 2006 and 2012:<br />

Seven-part Test for the Grey-headed Flying-fox<br />

The Grey-headed Flying-fox (Pteropus poliocephalus), is listed as ‘Vulnerable’ under Schedule 2 of the NSW<br />

TSC Act 1995 and the Commonwealth EPBC Act 1999. Although not detected during the current field<br />

investigations; the species was recorded flying over the Subject Property during an earlier survey conducted<br />

by UBM in 2006. The Grey-headed Flying-fox in known to frequent bushland on Sydney’s North Shore, and it<br />

is possible that this species would utilise the resources of the Subject Property when local eucalyptus trees<br />

are in flower; this being a primary food source for this species.<br />

(a) “…in the case of a threatened species, whether the action proposed is likely to have an adverse effect on<br />

the life cycle of the species such that a viable local population of the species is likely to be placed at risk of<br />

extinction…”<br />

The potential subdivision and associated residential development is unlikely to impact on the<br />

foraging resources for the Grey-headed Flying-fox as only a small area will be cleared. Therefore, the<br />

Planning Proposal or future potential subdivision, as envisaged on the concept plan accompanying<br />

the Planning Proposal, is unlikely to disrupt the life cycle of the species such that a local viable<br />

population would be placed at risk of extinction.<br />

(b) ”…in the case of an endangered population, whether the action proposed is likely to have an adverse<br />

effect on the life cycle of the species that constitutes the endangered population such that a viable local<br />

population of the species is likely to be placed at risk of extinction…”<br />

An ‘endangered population’ is defined as a “population specified in Part 2 of Schedule 1” of the TSC<br />

Act. Therefore the Grey-headed Flying-fox is not an endangered population.<br />

(c) “…in the case of an endangered ecological community or critically endangered ecological community,<br />

whether the action proposed:<br />

(i) ..is likely to have an adverse effect on the extent of the ecological community such that its local<br />

occurrence is likely to be placed at risk of extinction, or<br />

(ii).. is likely to substantially and adversely modify the composition of the ecological community such<br />

that its local occurrence is likely to be placed at risk of extinction...”<br />

An Endangered <strong>Ecological</strong> Community means an ecological community specified in Part 3 of Schedule<br />

1 of the TSC Act. Therefore, this item is not applicable to a threatened species.<br />

(d) “…in relation to the habitat of a threatened species, population or ecological community:<br />

(i)... the extent to which habitat is likely to be removed or modified as a result of the action proposed…”,<br />

and<br />

(ii) … whether an area of habitat is likely to become fragmented or isolated from other areas of habitat<br />

as a result of the proposed action…, and<br />

(iii)…the importance of the habitat to be removed, modified, fragmented or isolated to the long-term<br />

survival of the species, population or ecological community in the locality…<br />

UBM <strong>Ecological</strong> Consultants Pty Ltd Page 63


<strong>Flora</strong> & <strong>Fauna</strong> <strong>Survey</strong> & <strong>Ecological</strong> <strong>Assessment</strong>s – 35 Water Street Wahroonga<br />

Five (5) potential feed trees occur within the small (173 sq metres or 2.74%) of BGHF Habitat likely to<br />

be cleared on the Subject Sites potential Lots 3 and 4 may provide seasonal foraging habitat for this<br />

species, however no roost sites occur on the site or nearby. Other much larger areas of foraging<br />

habitat occur in bushland in the Locality and throughout the Region, including a number of dedicated<br />

conservation reserves. The Planning Proposal and the subdivision, as envisaged on the concept plan<br />

accompanying the Planning Proposal, is not likely to modify or remove a significant area of habitat.<br />

Trees to be removed that are a potential food source for the Grey-headed Flying-fox are four (4)<br />

Sydney Blue Gums (Eucalyptus saligna) and one (1) Rough-barked Applebox (Angophora floribunda).<br />

Flying-foxes are highly mobile species and regularly fly over cleared and highly urbanised areas. The<br />

Planning Proposal and the potential subdivision envisaged on the concept plan accompanying the<br />

Planning Proposal is unlikely to significantly impact upon habitat connectivity to any other bushland<br />

areas (which are limited), and areas of known habitat are not likely to become isolated from<br />

currently interconnecting or proximate areas of habitat.<br />

Foraging habitat to be removed from the Subject Property (173 sq metres, including five [5] feed<br />

trees), is minimal compared to other available habitat in the Locality. It will not affect the long-term<br />

viability of the species.<br />

(e) “…whether the action proposed is likely to have an adverse effect on critical habitat (either directly or<br />

indirectly)…”<br />

The Subject Property is not listed as critical habitat under Part 3 Division 1 of the TSC Act. Therefore,<br />

no critical habitat would be adversely affected by the draft Proposal.<br />

(f) “…whether the action proposed is consistent with the objectives or actions of a recovery plan or threat<br />

abatement plan…”<br />

A Draft National Recovery Plan has been prepared for the Grey-headed Flying-fox (DECCW 2009).<br />

The following objective is relevant to this Proposal: to identify and protect foraging habitat critical to<br />

the survival of Grey-headed Flying-foxes throughout their range. However, given the very small<br />

amount of habitat likely to be disturbed by the Proposal (173 sq metres and the removal of five [5]<br />

potential feed trees), it is highly unlikely that this stand of vegetation would be identified as a<br />

priority foraging area.<br />

(g) “…whether the action proposed constitutes or is part of a key threatening process or is likely to result in<br />

the operation of, or increase the impact of, a key threatening process...”<br />

The proposed project will involve land clearance and soil disturbance. As such it will or may involve<br />

a number of Key Threatening Processes under the TSC Act:<br />

Clearing of native vegetation (173 sq metres);<br />

The removal of dead trees, dead wood and logs; and<br />

Predation by the feral European Red Fox, which although not recorded on site, may visit the<br />

Subject Property from time to time.<br />

UBM <strong>Ecological</strong> Consultants Pty Ltd Page 64


<strong>Flora</strong> & <strong>Fauna</strong> <strong>Survey</strong> & <strong>Ecological</strong> <strong>Assessment</strong>s – 35 Water Street Wahroonga<br />

Invasion of native vegetation by exotic vines, perennial grasses and woody weeds does not apply as<br />

these are already on site in large numbers.<br />

With the exception of the European Red Fox threat abatement plan, no threat abatement plans<br />

relevant to the threatening processes mentioned above have been prepared by the NSW National<br />

Parks and Wildlife Service to date.<br />

Expected impact on the Grey-headed Flying-fox<br />

The Planning Proposal and potential future subdivision, as envisaged on the concept plan accompanying the<br />

Planning Proposal, will remove a small amount of Blue Gum High Forest habitat (173 sq m) that could be<br />

utilised by the Grey-headed Flying-fox seasonally, when eucalypts are in flower. The remainder of the BGHF<br />

Habitat on the Subject Property (@ 6,177 sq metres) will be retained, rehabilitated according to the adopted<br />

BGHF Habitat Vegetation Management Plan (UBM 2007), and managed in perpetuity.<br />

Given the mobility and ability to adapt to the urban environment, as well as the small area of vegetation to<br />

be removed, it is unlikely that the Planning Proposal or a potential future subdivision as envisaged on the<br />

concept plan accompanying the Planning Proposal will have a detrimental effect on any Grey-headed Flyingfox<br />

individuals or populations that have potential to use the Subject Property.<br />

It is considered that Planning Proposal and future subdivision, as envisaged on the concept plan submitted<br />

with the Planning Proposal, would not have a significant impact on the Grey-headed Flying-fox, its<br />

populations or habitats. Therefore, the preparation of a Species Impact Statement that further considers<br />

the impacts of the Proposal on these fauna species is NOT REQUIRED.<br />

Seven-part Test for the Gang-gang Cockatoo<br />

The Gang-gang Cockatoo (Callocephalon fimbriatum), is listed as ‘Vulnerable’ under Schedule 2 of the NSW<br />

TSC Act 1995. The Gang-gang Cockatoo is also listed under the TSC Act as an ‘Endangered Population’ within<br />

the Hornsby and Ku-ring-gai Local Government Areas. Although not detected during the current field<br />

investigations, there are 31 records of the species occurring within the Region (Table 4.4). Field<br />

investigations conducted by UBM in 2006 indentified Gang-gang Cockatoos flying over the Subject Property.<br />

The Gang-gang Cockatoo has different habitat requirements depending on the season. The resources of the<br />

Subject Property are likely to be only utilised during the winter months when the species is known to<br />

accommodate more open eucalypt forests and woodlands at lower altitudes than during summer.<br />

(a) “…in the case of a threatened species, whether the action proposed is likely to have an adverse effect on<br />

the life cycle of the species such that a viable local population of the species is likely to be placed at risk of<br />

extinction…”<br />

The Planning Proposal and potential future subdivision, as envisaged on the concept plan<br />

accompanying the Planning Proposal, is unlikely to impact on the foraging resources for the Ganggang<br />

Cockatoo as only a small area will be cleared (173 sq metres). Any native trees with nesting<br />

UBM <strong>Ecological</strong> Consultants Pty Ltd Page 65


<strong>Flora</strong> & <strong>Fauna</strong> <strong>Survey</strong> & <strong>Ecological</strong> <strong>Assessment</strong>s – 35 Water Street Wahroonga<br />

hollows will also be retained. Therefore, the Proposal is unlikely to disrupt the life cycle of the<br />

species such that a local viable population would be placed at risk of extinction.<br />

(b) ”…in the case of an endangered population, whether the action proposed is likely to have an adverse<br />

effect on the life cycle of the species that constitutes the endangered population such that a viable local<br />

population of the species is likely to be placed at risk of extinction…”<br />

The listed endangered population is found in the Ku-ring-gai and Hornsby local government areas. It<br />

is known to inhabit areas of Lane Cove National Park, Pennant Hills Park and other forested gullies in<br />

the area, where most nesting is likely to take place.<br />

The Subject Property is located in a fully developed residential suburb, and at some distance (> one<br />

[1] km) from the species’ known nesting sites in Lane Cove National Park and Ku-ring-gai Chase<br />

National Park. As such, the Proposal is unlikely to disrupt the life cycle of the species such that the<br />

endangered population would be placed at risk of extinction.<br />

(c) “…in the case of an endangered ecological community or critically endangered ecological community,<br />

whether the action proposed:<br />

(i) ..is likely to have an adverse effect on the extent of the ecological community such that its local<br />

occurrence is likely to be placed at risk of extinction, or<br />

(ii).. is likely to substantially and adversely modify the composition of the ecological community such<br />

that its local occurrence is likely to be placed at risk of extinction...”<br />

An Endangered <strong>Ecological</strong> Community means an ecological community specified in Part 3 of Schedule<br />

1 of the TSC Act. Therefore, this item is not applicable to a threatened species.<br />

(d) “…in relation to the habitat of a threatened species, population or ecological community:<br />

(i)... the extent to which habitat is likely to be removed or modified as a result of the action proposed…”,<br />

and<br />

(ii) … whether an area of habitat is likely to become fragmented or isolated from other areas of habitat<br />

as a result of the proposed action…, and<br />

(iii)…the importance of the habitat to be removed, modified, fragmented or isolated to the long-term<br />

survival of the species, population or ecological community in the locality…<br />

Although a small proportion of foraging habitat will be removed from the Subject Property (173 sq<br />

metres), all potential nesting habitat for the species elsewhere on the Property will be retained (@<br />

6,177 sq metres). The Planning Proposal and potential future subdivision, as envisaged on the<br />

concept plan accompanying the Planning Proposal, is not likely to fragment or isolate any areas of<br />

habitat for this species as it is capable of flying over cleared and developed urban areas.<br />

The Subject Property affords foraging habitat and some potential nesting habitat for the species.<br />

However, as the Gang-gang Cockatoo is highly mobile and moves around according to the availability<br />

of foraging habitat, it is likely to use a much broader area of habitat, including the large bushland<br />

UBM <strong>Ecological</strong> Consultants Pty Ltd Page 66


<strong>Flora</strong> & <strong>Fauna</strong> <strong>Survey</strong> & <strong>Ecological</strong> <strong>Assessment</strong>s – 35 Water Street Wahroonga<br />

areas within Lane Cove National Park and Ku-ring-gai Chase National Park. Therefore the small area<br />

of habitat potentially affected by subdivision potential envisaged under the Proposal (173 sq metres)<br />

is not essential habitat for the species.<br />

(e) “…whether the action proposed is likely to have an adverse effect on critical habitat (either directly or<br />

indirectly)…”<br />

The Subject Property is not listed as critical habitat under Part 3 Division 1 of the TSC Act. Therefore,<br />

no critical habitat would be adversely affected by the draft Proposal.<br />

(f) “…whether the action proposed is consistent with the objectives or actions of a recovery plan or threat<br />

abatement plan…”<br />

No Recovery Plans or Threat Abatement Plans (either finalised or draft) have been prepared for the<br />

Gang-gang Cockatoo. However, DECCW has identified a number of priority actions for these species<br />

(DECCW 2009b).<br />

Actions which may be relevant to the management of habitat for the Gang Gang Cockatoo on the<br />

Subject Property include:<br />

Development of a strategy that includes street tree or other plantings, which include browse<br />

plant species within reserves and private residences.<br />

(g) “…whether the action proposed constitutes or is part of a key threatening process or is likely to result in<br />

the operation of, or increase the impact of, a key threatening process...”<br />

The following key threatened processes as they potentially impact on the Gang Gang Cockatoo may<br />

be applicable to the Subject Property:<br />

Clearing of native vegetation, as this will clear foraging habitat. However, potential nesting sites<br />

and other potential foraging habitat will be retained elsewhere on the Subject Property;<br />

Competition from feral honeybees, as they can form hives in tree hollows that also form<br />

potential nesting habitat for the Gang-gang Cockatoo. The Proposal is not likely to exacerbate<br />

this process;<br />

<strong>Ecological</strong> consequences of high frequency fires, as fire can destroy tree hollows that form<br />

potential nesting habitat. It is envisaged that fire will not be part of the management of the<br />

BGHF Habitat on the Subject Property;<br />

Infection by Psittacine circoviral (beak and feather) disease affecting endangered psittacine<br />

species and populations, as it can leave Gang-gang Cockatoos prone to other infections.<br />

However, the Proposal will not exacerbate the likelihood of this disease infecting a local<br />

population;<br />

Predation by the European Red Fox as fledglings can become prey items for foxes. Foxes may<br />

occur or visit the Subject Property from time to time (although not recorded), but are not likely<br />

to be increased in number by the Proposal; and<br />

The removal of dead wood and dead trees, as dead trees are often hollow and contain potential<br />

nesting habitat. Some dead trees may be removed but all trees with hollows will be retained on<br />

the Subject Property.<br />

UBM <strong>Ecological</strong> Consultants Pty Ltd Page 67

Expected impact on the Gang-gang Cockatoo<br />

The Planning Proposal or potential future subdivision, as envisaged on the concept plan accompanying the<br />

Planning Proposal, will potentially remove a small amount of BGHF Habitat (173 sq metres or 2.74% of the<br />

total area) that could potentially be utilised by the Gang-gang Cockatoo during the winter months for<br />

foraging. However, the remainder of the BGHF Habitat on the Subject Property 6,177 sq metres) will be<br />

retained, rehabilitated under the adopted BGHF Vegetation Management Plan (UBMC 2007), and managed<br />

in perpetuity.<br />

Given the species’ mobility and ability to adapt to the urban environment, as well as the small area of<br />

vegetation to be removed or impacted (173 sq metres or 2.74% of the total BGHF Habitat area), it is unlikely<br />

that potential subdivision envisaged under the Proposal will have a detrimental effect on Gang-gang<br />

Cockatoo individuals or populations that have potential to use the Subject Property from time to time.<br />

It is considered that the Planning Proposal and future subdivision, as envisaged on the concept plan<br />

submitted with the Planning Proposal, would not have a significant impact on the Gang-gang Cockatoo, its<br />

populations or habitats. Therefore, the preparation of a Species Impact Statement that further considers<br />

the impacts of the Proposal on these species is NOT REQUIRED.<br />

Seven-part Test for the Powerful Owl<br />

The Powerful Owl (Ninox strenua) is listed as ‘Vulnerable’ under Schedule 2 of the NSW TSC Act 1995.<br />

Tree hollows are particularly important for all forest owl species. They not only provide habitat for hollowdwelling<br />

arboreal marsupials (possums and gliders), which comprise a large proportion of the Owl’s diet, but<br />

are also potential nesting sites (Higgins 1999). Estimates of the home range of the Powerful Owl is 300 –<br />

1500 hectares (DEC 2006).<br />

(a) “…in the case of a threatened species, whether the action proposed is likely to have an adverse effect on<br />

the life cycle of the species such that a viable local population of the species is likely to be placed at risk of<br />

extinction…”<br />

There is potential for the Powerful Owl to utilise the Subject Property for hunting and roosting. No<br />

hollows of suitable size for nesting are present. The Planning Proposal and potential subdivision as<br />

envisaged under the concept plan accompanying the Planning Proposal, will potentially remove a<br />

small amount of BGHF Habitat (173 sq metres or 2.74% of the total Habitat area). This Proposal will<br />

not significantly reduce the populations of suitable prey, and is therefore unlikely to have an adverse<br />

effect of the life cycles or place any local populations of the Powerful Owl at risk of extinction.<br />

(b) ”…in the case of an endangered population, whether the action proposed is likely to have an adverse<br />

effect on the life cycle of the species that constitutes the endangered population such that a viable local<br />

population of the species is likely to be placed at risk of extinction…”<br />

An endangered population is defined under the TSC Act as ‘a population specified in Part 2 of<br />

Schedule 1’. Therefore the Powerful Owl is not an endangered population.<br />

(c) “…in the case of an endangered ecological community or critically endangered ecological community,<br />

whether the action proposed:<br />

(i) ..is likely to have an adverse effect on the extent of the ecological community such that its local<br />

occurrence is likely to be placed at risk of extinction, or<br />

(ii).. is likely to substantially and adversely modify the composition of the ecological community such<br />

that its local occurrence is likely to be placed at risk of extinction...”<br />

An Endangered <strong>Ecological</strong> Community means an ecological community specified in Part 3 of Schedule<br />

1 of the TSC Act. Therefore, this item not applicable to a threatened species.<br />

(d) “…in relation to the habitat of a threatened species, population or ecological community:<br />

(i)... the extent to which habitat is likely to be removed or modified as a result of the action proposed…”,<br />

and<br />

(ii) … whether an area of habitat is likely to become fragmented or isolated from other areas of habitat<br />

as a result of the proposed action…, and<br />

(iii)…the importance of the habitat to be removed, modified, fragmented or isolated to the long-term<br />

survival of the species, population or ecological community in the locality…<br />

Although a small proportion of hunting and roosting habitat will be impacted or removed from the<br />

Subject Property (173 sq metres), the remainder of BHGF habitat on the Property will be retained (@<br />

6,177 sq metres). The Planning Proposal and potential future subdivision, as envisaged on the<br />

concept plan accompanying the Planning Proposal, is not likely to fragment or isolate any areas of<br />

habitat for this species as it is capable of flying over cleared and developed urban areas.<br />

The Subject Property affords some hunting habitat and some potential roosting habitat for the<br />

species. However, as the Powerful Owl is highly mobile and has a large home range, it is likely to use<br />

a much broader area of habitat for these purposes, including the large bushland areas within Lane<br />

Cove National Park and Ku-ring-gai Chase National Park. Therefore the small area of habitat<br />

potentially affected by the Proposal (173 sq metres) is not considered to be essential habitat for the<br />

species.<br />

The clearing or otherwise modification of this small area (173 sq metres) of bushland on the Subject<br />

Property is unlikely to impact on the long-term survival of the Powerful Owl within the Locality or<br />

Region.<br />

(e) “…whether the action proposed is likely to have an adverse effect on critical habitat (either directly or<br />

indirectly)…”<br />

The Subject Property is not listed as critical habitat under Part 3 Division 1 of the TSC Act. Therefore,<br />

no critical habitat would be adversely affected by the Proposal.<br />

(f) “…whether the action proposed is consistent with the objectives or actions of a recovery plan or threat<br />

abatement plan…”<br />

UBM <strong>Ecological</strong> Consultants Pty Ltd Page 69


<strong>Flora</strong> & <strong>Fauna</strong> <strong>Survey</strong> & <strong>Ecological</strong> <strong>Assessment</strong>s – 35 Water Street Wahroonga<br />

A Recovery Plan has been developed for large Forest Owls (including the Powerful Owl). Two (2) of<br />

the main issues identified in these Recovery Plans are clearing and fragmentation of habitat.<br />

The Planning Proposal and potential future subdivision will impact upon or clear 173 sq metres of<br />

BGHF Habitat on the Subject Property. This is not expected to have a significant impact on the<br />

resources available to the owls. The remainder of the BGHF Habitat on the Subject Property will<br />

remain intact.<br />

To date, there is no threat abatement plan for the Powerful Owl.<br />

(g) “…whether the action proposed constitutes or is part of a key threatening process or is likely to result in<br />

the operation of, or increase the impact of, a key threatening process...”<br />

Currently 32 Key threatening processes are defined under Schedule 3 of the TSC Act. The Planning<br />

Proposal would require the clearing of a small area of native vegetation (listed as a Key Threatening<br />

Process).<br />

No other key threatening processes are likely to be relevant to the protection of the Powerful Owls<br />

which might utilise the resources of the Subject Property.<br />

It is recommended that the largest possible area of BGHF habitat on the Subject Property is retained<br />

to minimise the impact of key threatening processes.<br />

Expected impact on the Powerful Owl<br />

The Planning Proposal and potential future subdivision proposal, as envisaged in the concept plan<br />

accompanying the Planning Proposal, will impact upon or remove a small amount (173 sq metres) of habitat<br />

that could be utilised by the Powerful Owl for hunting and roosting. The remainder of the BGHF habitat<br />

(6,177 sq metres) on the Subject Property will be retained and protected.<br />

Given that the prey of these species is highly adaptable to the urban environment, as well as the small area<br />

of vegetation to be removed, it is unlikely that the Planning Proposal will lead to a reduction of prey species<br />

resulting in a detrimental effect on Powerful Owl individuals or populations that have potential to use the<br />

Subject Property.<br />

It is considered that the Planning Proposal and potential future subdivision, as envisaged on the concept<br />

plan accompanyingthe Planning Proposal, would not have a significant impact on the Powerful Owl, its<br />

populations or habitats. Therefore, the preparation of a Species Impact Statement that further considers<br />

the impacts of the Proposal on this species is NOT REQUIRED.<br />

5 CONCLUSIONS & R ECOMMENDATIONS<br />

In conclusion, land within the Subject Property 35 Water Street Wahroonga has a soil landscape, geology and<br />

topography able to support BGHF – described in this Report as BGHF Habitat. The presence of 6,350 sq<br />

metres (0.635 ha) of BGHF in the Subject Property has been confirmed by the NSW Land & Environment<br />

Court (Proceedings 1113 of 2006) and this figure has been used in all subsequent (Cumberland Ecology 2007,<br />

UBMC 2007, UBM 2011) and current (UBM 2012) reports.<br />

The BGHF Habitat support a number of flora species associated with a number of shale-soil vegetation<br />

communities in the Sydney Bioregion; however the low abundance of native flora species present in the<br />

understorey, the very low % cover of locally indigenous flora species (~25%), the small size of the remnant<br />

vegetation in the Subject Property overall (6,350 sq metres, 0.635 ha), its isolation within a fully developed<br />

residential area, and its long-term land use and disturbance history means that the remnant vegetation in<br />

the Subject Property has not functioned as a viable, interactive native ecological community for many years.<br />

However, the stands of Sydney Blue Gum (Eucalyptus saligna) remaining in the Subject Property provide a<br />

genetic resource for the species and they form part of the remnant BGHF ecological community in the<br />

Locality and Region. Under the Planning Proposal and potential future subdivision, as envisaged on the<br />

concept plan accompanying the Planning Proposal, an area of 173 sq metres (2.74% o f the total BGHF<br />

Habitat area) and 11 BGHF trees will potentially be removed from the area proposed for possible<br />

subdivision, with nine (9) BGHF trees to be removed or impacted in potential Lots 3 and 4.<br />

The large remnant trees on the Subject Property, both native and introduced species, provide connectivity<br />

(albeit discontinuous) to trees in neighbouring properties and local bushland reserves, and they also provide<br />

habitat and food resources for a range of urban-tolerant native fauna; these being important ecological<br />

services within a wholly residential landscape. UBM recommends that wherever possible, in those areas not<br />

proposed for development all trees in good condition and which provide no hazard to public safety should<br />

be protected, retained and incorporated in any future landscape design.<br />

There will be a potential loss of 173 sq metres of BGHF Habitat for development in potential Subject Sites 3<br />

and 4. This represents a loss of 2.74% of the total area of BGHF Habitat in the Subject Property overall (@<br />

6,350 sq metres). It should also be noted that the loss of only 2.74% of BGHF Habitat identified under the<br />

potential future subdivision compares favourably with the 4.9% loss of this community which would have<br />

occurred under the approved Hospital proposal.<br />

Further, under the potential future subdivision proposal envisaged in the concept plan accompanying the<br />

Planning Proposal, 6,177 sq metres of BGHF Habitat would be retained, rehabilitated and appropriately<br />

managed under the adopted BGHF Habitat Vegetation Management Plan (UBMC 2007). This compares<br />

favourably to only 6,034 sq metres of the community which would have been retained under the approved<br />

Hospital proposal (providing a net gain of 323 sq metres)<br />

It is however, recommended that the loss of 173 sq metres of BGHF Habitat, although small, should be<br />

‘offset’ against a restoration and management program to rehabilitate the remaining area of BBGHF Habitat<br />

within the larger Subject Property.<br />

A Vegetation Management Plan for the BGHF Habitat at 35 Water Street has been prepared (UBMC 2007),<br />

approved by DECCW/OEH, and adopted by Ku-ring-gai Council. This Plan provides for bush regeneration<br />

works over a period of five (5) years, and will cover bushland restoration and rehabilitation works in all of<br />

the BGHF Habitat Area mapped within the Subject Property, and includes those parts of BGHF Habitat which<br />

intrude marginally into potential new Lots 3 and 4.<br />

Scientific Licence 132C for the purposes of science, education or conservation under the National Parks &<br />

Wildlife Act 1979 has been obtained from OEH to provide for the implementation of on-ground works.<br />

However, to date, no works under this Plan have been undertaken. Scientific License 132C is currently in the<br />

name of the previous landowner Waterbrook Pty Ltd, so it will be necessary to apply to the Licensing Division<br />

of OEH to reissue the License in the name of the current landowner Bellevue Projects Pty Ltd. All other<br />

licence conditions will remain unchanged.<br />

It is considered that the implementation of the adopted Vegetation Management Plan for the remaining<br />

6,177 sq metres of BGHF Habitat in the Subject Property will provide an adequate offset for the loss of173 sq<br />

(2.74%) metres of this Habitat in the Development Areas of potential Lots 3 and 4 within Area 2.<br />

Further, the loss of 2.74% of BGHF Habitat within the Subject Property is well within the maximum 5% loss<br />

for BGHF proposed by Dr P. Smith as an expert witness appearing in the Land and Environment Court and<br />

adopted by the Court.<br />

The Planning Proposal and potential subdivision proposal, as envisaged by the concept plan accompanying<br />

the Planning Proposal, will result in the restoration of historic Rippon Grange, its gardens and arboretum,<br />

and allow for the conservation and future management of the BGHF Habitat on the Subject Property.<br />

7 APPENDICES<br />

APPENDIX 1: Final Determination – Blue Gum High Forest<br />

Blue Gum High Forest in the Sydney Basin Bioregion - critically endangered ecological community listing<br />

NSW Scientific Committee - final determination<br />

The Scientific Committee, established by the Threatened Species Conservation Act, has made a Final<br />

Determination to list the Blue Gum High Forest in the Sydney Basin Bioregion, as a critically endangered<br />

ecological community in Part 2 of Schedule 1A of the Act, and as a consequence omit reference to the Blue<br />

Gum High Forest in Part 3 of Schedule 1 of the Act. Listing of critically endangered ecological communities is<br />

provided for by Part 2 of the Act.<br />

The Scientific Committee has found that:<br />

1. Blue Gum High Forest in the Sydney Basin Bioregion is the name given to the ecological community<br />

characterised by the species assemblage listed in paragraph 2. All sites are within the Sydney Basin<br />

Bioregion.<br />

2. Blue Gum High Forest in the Sydney Basin Bioregion is characterised by the following assemblage of<br />

3. The total species list of the community is considerably larger than that given above, with many species<br />

present in only one or two sites or in low abundance. The species composition of a site will be influenced by<br />

the size of the site, recent rainfall or drought condition and by its disturbance (including fire) history. The<br />

number of species and the above ground relative abundance of species will change with time since fire, and<br />

may also change in response to changes in fire regime (including changes in fire frequency). At any one time,<br />

above ground individuals of some species may be absent, but the species may be represented below ground<br />

in the soil seed banks or as dormant structures such as bulbs, corms, rhizomes, rootstocks or lignotubers.<br />

The list of species given above is of vascular plant species; the community also includes micro-organisms,<br />

fungi, cryptogamic plants and a diverse fauna, both vertebrate and invertebrate. These components of the<br />

community are poorly documented.<br />

4. Blue Gum High Forest is dominated by a tall canopy of eucalypts that may exceed 30 m in height. Its<br />

understorey is typically multi-layered with a midstorey of mesophyllous shrubs and small trees and a diverse<br />

ground layer of herbs, ferns and some grasses. Most stands of the community are in a state of regrowth<br />

after past clearing or logging activities, and consequently trees may be shorter, less dense or more dense<br />

than less disturbed stands. Blue Gum High Forest is dominated by either Eucalyptus pilularis (Blackbutt) or E.<br />

saligna (Sydney Blue Gum). Angophora costata (Smooth-barked Applebox) is frequently observed in<br />

remnants close to the shale/sandstone boundary, but also occurs infrequently on deep shale soils, as does A.<br />

floribunda (Rough-barked Applebox). Eucalyptus paniculata (Grey Ironbark) is typically found on upper<br />

slopes. A relatively diverse stratum of small trees is usually present, and includes Pittosporum undulatum<br />

(Sweet Pittosporum), Elaeocarpus reticulatus (Blueberry Ash) and Allocasuarina torulosa (Forest Oak). Shrub<br />

species are typically mesophyllous, such as Breynia oblongifolia (Coffee Bush), Pittosporum revolutum,<br />

(Yellow Pittosporum), Clerodendrum tomentosum, Notelaea longifolia forma longifolia (Large Mock-olive),<br />

Maytenus sylvestris (Narrow-leaved Orange Bark), Polyscias sambucifolia subsp. A (Elderberry Panax) and<br />

Rapanea variabilis (Muttonwood). Mesophyllous species are generally more common in gullies associated<br />

with both shale and volcanic soils than slopes and ridgetops. Sclerophyllous species such as Persoonia<br />

linearis (Narrow-leaved Geebung) and Leucopogon juniperinum (Prickly Bearded-heath) occur more<br />

frequently closer to the shale/sandstone boundary. The ground stratum is often dense and contains a<br />

mixture of herb, grass and fern species including Adiantum aethiopicum, Entolasia marginata (Bordered<br />

Panic), Lomandra longifolia (Spiny-headed Matrush), Calochlaena dubia (Common Groundfern), Dianella<br />

caerulea (Blue Flax Lily), Pseuderanthemum variabile (Pastel Flower) and Oplismenus imbecillis. Vine species<br />

are also frequently present, in particular Tylophora barbata (Bearded Tylophora), Eustrephus latifolia,<br />

(Wombat Berry), Clematis aristata (Old Man's Beard) and Pandorea pandorana (Wonga Wonga Vine).<br />

5. While no systematic fauna surveys have been carried out across the range of Blue Gum High Forest a<br />

number of mammal and bird species listed as threatened in NSW have been recorded as resident or<br />

UBM <strong>Ecological</strong> Consultants Pty Ltd Page 77


<strong>Flora</strong> & <strong>Fauna</strong> <strong>Survey</strong> & <strong>Ecological</strong> <strong>Assessment</strong>s – 35 Water Street Wahroonga<br />

transient in the community. These include the Grey-headed Flying Fox (Pteropus poliocephalus), Yellowbellied<br />

Sheathtail-bat (Saccolaimus flaviventris), Glossy Black cockatoo (Calyptorhynchus lathami) and the<br />

Powerful Owl (Ninox strenua).<br />

6. Blue Gum High Forest is typically associated with soils derived from Wianamatta Shale (Tozer 2003),<br />

though may occur in adjacent areas underlain by Hawkesbury Sandstone. The community also occurs on<br />

soils associated with localised volcanic intrusions, 'diatremes' (Benson and Howell 1994). Typically, Blue Gum<br />

High Forest occurs more than 100m above sea level, where rainfall exceeds 1050 mm per annum, although it<br />

may be present in sheltered locations with lower rainfall (Tozer 2003). In drier areas and approaching the<br />

shale/sandstone boundary, it intergrades with Sydney Turpentine Ironbark Forest, which is currently listed as<br />

an Endangered <strong>Ecological</strong> Community under the TSC Act. Stands that exhibit intermediate characteristics are<br />

collectively covered by the Determinations of these communities and may be diagnosed by detailed<br />

consideration of the assemblage of species present at the site.<br />

7. Vegetation surveys carried out across the range of Blue Gum High Forest include those of Benson and<br />

Howell (1990, 1994) and Tozer (2003). All of these studies describe and map this community as 'Blue Gum<br />

High Forest', including map unit 6b 'Tall open-forest: Eucalyptus pilularis – Eucalyptus saligna' of Benson and<br />

Howell (1994) and map unit 153 of Tozer (2003). In addition, Benson and Howell (1994) map separately that<br />

part of this community which occurs on soils associated with diatremes as 'Glen Forest, map unit 6c, i. Tall<br />

open-forest: Eucalyptus saligna', noting that this vegetation was 'very similar to the Blue Gum High Forest of<br />

the north shore [i. e. map unit 6b]'. Blue Gum High Forest belongs to the North Coast Wet Sclerophyll Forests<br />

vegetation class of Keith (2004).<br />

8. Blue Gum High Forest is found on the north shore and northern suburbs of Sydney and has been recorded<br />

from the local government areas of Lane Cove, Willoughby, Ku-ring-gai, Hornsby, Baulkham Hills, Ryde and<br />

Parramatta within the Sydney Basin Bioregion and may occur elsewhere in the Bioregion.<br />

9. Blue Gum High Forest has a very highly restricted geographic distribution, and is currently estimated to<br />

cover an extant area of less than 200 ha (Tozer 2003). The distribution comprises a series of small remnant<br />

patches, the largest of which is less than 20ha. Highly modified relics of the community also persist as small<br />

clumps of trees without a native understorey. All remnants of the community are now surrounded by urban<br />

development. Consequently, the distribution of Blue Gum High Forest is severely fragmented. Fragmentation<br />

of habitat contributes to a very large reduction in the ecological function of the community.<br />

10. Prior to European settlement, about 200 years ago, Blue Gum High Forest is estimated to have covered<br />

an area of approximately 3700 ha (Tozer 2003). Its current extent amounts to less than 5% of this original<br />

distribution. The dominant eucalypts of the community live for several hundred years. Blue Gum High Forest<br />

has therefore undergone a very large reduction in its geographic distribution within a time span appropriate<br />

to the life cycle and habitat characteristics of its component species. Small-scale clearing associated with<br />

residential subdivision, road upgrading, extension and maintenance of service easements, etc. pose a threat<br />

of ongoing decline in the extent of the community. Clearing of native vegetation is listed as a Key<br />

Threatening Process under the Threatened Species Conservation Act 1995.<br />

11. Changes in structure of Blue Gum High Forest have occurred as a consequence of the extensive removal<br />

of large old trees. A number of stands of Blue Gum Forests have highly modified understories, in which the<br />

native woody component has been largely replaced by woody exotic species or by increased abundance of<br />

native and exotic grasses. Continued underscrubbing, frequent burning and mowing may maintain the<br />

understorey in an artificially open state and prevent recruitment of species with the community. The loss of<br />

large trees removes essential habitat for a range of tree-dependent fauna (Gibbons and Lindenmeyer 1996).<br />

The reduction of understorey complexity, through the reduction of native shrub cover, degrades habitat for<br />

a range of bird and mammal species (Catling 1991). These processes contribute to a very large reduction in<br />

the ecological function of the community.<br />

12. The influx of stormwater, which brings excessive moisture, pollutants and nutrients to the remnant<br />

forests from surrounding urban areas, is a significant ongoing threat to the ecological integrity of Blue Gum<br />

High Forest. This, together with the legacy of past disturbances and the abundance and dispersal of weed<br />

propagules from nearby urban areas, results in the invasion, establishment and spread of weeds (Thomson<br />

and Leishman 2005). Problematic weed species in Blue Gum High Forest include the following:<br />

Asparagus asparagoides<br />

Cinnamomum camphora<br />

Lantana camara<br />

Ligustrum lucidum<br />

Ligustrum sinense<br />

Ochna serrulata<br />

Passiflora edulis<br />

Passiflora subpeltata<br />

Pennisetum clandestunum<br />

Rubus ulmifolius<br />

Senna colutioides<br />

Tradescantia fluminensis<br />

Bridal Creeper<br />

Camphor laurel<br />

Lantana<br />

Large-leaved Privet<br />

Small-leaved Privet<br />

Passionfruit<br />

Blackberry<br />

'Invasion and establishment of exotic vines and scramblers', 'Invasion of native plant communities by exotic<br />

perennial grasses' and 'Invasion, establishment and spread of Lantana (Lantana camara L. sens. lat)' are<br />

listed as Key Threatening Processes under the Threatened Species Conservation Act. The influx of<br />

stormwater, pollutants and nutrients, and the invasion of weeds contribute to a very large reduction in the<br />

ecological function of the community.<br />

13. Blue Gum High Forest in the Sydney Basin Bioregion is eligible to be listed as a critically endangered<br />

ecological community as, in the opinion of the Scientific Committee, it is facing an extremely high risk of<br />

extinction in New South Wales in the immediate future, as determined in accordance with the following<br />

criteria as prescribed by the Threatened Species Conservation Regulation 2002:<br />

Clause 25<br />

The ecological community has undergone, is observed, estimated, inferred or reasonably suspected to have<br />

undergone, or is likely to undergo within a time span appropriate to the life cycle and habitat characteristics<br />

of its component species:<br />

(a) a very large reduction in geographic distribution.<br />

UBM <strong>Ecological</strong> Consultants Pty Ltd Page 79


<strong>Flora</strong> & <strong>Fauna</strong> <strong>Survey</strong> & <strong>Ecological</strong> <strong>Assessment</strong>s – 35 Water Street Wahroonga<br />

Clause 26<br />

The ecological community's geographic distribution is estimated or inferred to be:<br />

(b) very highly restricted,<br />

and the nature of its distribution makes it likely that the action of a threatening process could cause it to<br />

decline or degrade in extent or ecological function over a time span appropriate to the life cycle and habitat<br />

characteristics of the ecological community's component species.<br />

Clause 27<br />

The ecological community has undergone, is observed, estimated, inferred or reasonably suspected to have<br />

undergone, or is likely to undergo within a time span appropriate to the life cycle and habitat characteristics<br />

of its component species:<br />

(a) a very large reduction in ecological function,<br />

as indicated by any of the following:<br />

(b) change in community structure<br />

(c) change in species composition<br />

(f) disruption of ecological processes<br />

(g) invasion and establishment of exotic species<br />

(h) degradation of habitat<br />

(i) fragmentation of habitat<br />
