Don Reserve Environmental Management Plan<br />
Page 3 of 56<br />
EXECUTIVE SUMMARY<br />
This <strong>management</strong> <strong>plan</strong> aims to protect, restore and manage<br />
the remnant bushland of the Don Reserve to provide the<br />
necessary elements for a healthy ecosystem.<br />
The competing interests of urban activities together with<br />
natural occurrences as shown by the fierce windstorm of July<br />
2000 have progressively degraded the remnant vegetation. It is<br />
proposed to strategically manage the Don Reserve and<br />
instigate appropriate and coordinated on-ground works to<br />
remove competing weeds, encourage natural revegetation and<br />
monitor ecological communities including the habitat of<br />
threatened species such as Swift Parrot and Eastern Barred<br />
Bandicoot. Background information through fauna, flora<br />
surveys and weed mapping provide <strong>management</strong> strategies to<br />
direct appropriate conservation & rehabilitation activities.<br />
The 70Ha Don Reserve is dominated by shrubby black gum<br />
forest (Eucalyptus ovata) with intermittent areas of brown top<br />
stringy bark forest (E. obliqua), coastal white gum forest (E.<br />
viminalis) and coastal black peppermint forest (E. amygdalina).<br />
Swamp paperbark forest (Melaleuca ericifolia) also occurs<br />
along the estuarine flats and in wet sections of the Reserve.<br />
Shrubby black gum forest and coastal white gum forest are<br />
extremely important conservation elements as both are<br />
endangered <strong>plan</strong>t communities within Tasmania. The Don<br />
Reserve supports the largest remnant of black gum forest<br />
along the entire northern Tasmanian coastline. Such trees are<br />
also a very important food source for the endangered swift<br />
parrot (Lathamus discolor) as it migrates between Tasmania<br />
and mainland Australia. The swift parrot breeds exclusively in<br />
Tasmania showing Tasmania’s importance to the survival of<br />
the species. The Don Reserve also functions as an important<br />
corridor for <strong>plan</strong>t and animal distribution from the coast to<br />
Kelcey Tier Greenbelt. The Reserve is a significant<br />
conservation asset for <strong>Devonport</strong> and the North West region of<br />
Tasmania.<br />
The Reserve is important for recreational use by locals and<br />
visitors alike for walking, cycling and fitness pursuits including<br />
swimming at the <strong>Devonport</strong> Aquatic Centre. These activities<br />
are seen to contribute to the experience of the Reserve but<br />
require appropriate <strong>management</strong> practices to coexist with the<br />
bushland environment.
Don Reserve Environmental Management Plan<br />
Page 4 of 56<br />
This <strong>management</strong> <strong>plan</strong> will also address the concerns of fire in<br />
the Reserve and contribute to an appropriate fire <strong>management</strong><br />
strategy to guide future use and maintenance procedures.<br />
The combination of spectacular bush scenery, wildlife and<br />
recreational activities provide an excellent opportunity for<br />
interpretation signage and <strong>environmental</strong> education. The<br />
Reserve also has educational value in showing what can be<br />
achieved given the efforts of volunteers such as the Friends of<br />
Don Reserve group.<br />
This <strong>management</strong> <strong>plan</strong> advocates the prevention of bush<br />
degradation and as such it is imperative to instigate<br />
rehabilitation works aiming for a self sustaining and healthy<br />
ecosystem within an urban environment. The success of this<br />
<strong>management</strong> <strong>plan</strong> requires a joint commitment between<br />
<strong>Devonport</strong> <strong>City</strong> Council, relevant stakeholders and the<br />
community.<br />

This <strong>plan</strong> is intended to direct stakeholders / land manager (eg<br />
<strong>Devonport</strong> <strong>City</strong> Council) and community groups. It has been prepared<br />
by <strong>Devonport</strong> <strong>City</strong> Council’s Environmental Planner, John Molnar, with<br />
funding from the Australian Government’s Natural Heritage Trust.<br />

1.2 Location and Description<br />
The <strong>City</strong> of <strong>Devonport</strong> is located on the Mersey River in the heart of the<br />
North West Coast of Tasmania. It is a river port and the home port of<br />
the current Spirit of Tasmania I & II, the passenger and vehicular ferries<br />
which connects <strong>Devonport</strong> with Melbourne. Whilst located close to the<br />
Tasmanian high country, including spectacular Cradle Mountain,<br />
<strong>Devonport</strong> is favoured with a temperate coastal climate influenced by<br />
the ocean. The Council is small in area at only 116 sq. kms however is<br />
the centre for a rich agricultural district which produces over 40% of<br />
Tasmania's vegetable crops (Beans, Onions, Peas, and Potatoes etc)<br />
and very significant values of cereals, oil poppies, pyrethrum and other<br />
crops. Dairy production and processing is also significant<br />
<strong>Devonport</strong> is particularly well provided for in its <strong>reserve</strong>s and<br />
recreational facilities. Parkland, which has been established along the<br />
Mersey Estuary, along its coastal foreshore and in the Don River<br />
valley, contains a cycling & walking track linking many of the <strong>City</strong>'s<br />
recreational facilities.<br />
The Don Reserve is a narrow strip, between 20 & 100 metres wide and<br />
about 2 kilometres long, of remnant vegetation on the eastern bank of<br />
the Don River. It is situated 5 kilometres west of the city centre of<br />
<strong>Devonport</strong>, Tasmania and occupies an area of approximately 70Ha. To<br />
the north is Bass Strait and the marine habitat of the Don Heads and<br />
Coles Beach, to the east the urban areas of <strong>Devonport</strong> which extends
Don Reserve Environmental Management Plan<br />
Page 6 of 56<br />
right to the edge of the Reserve, whilst the west is dominated by rural<br />
and rural residential activities on the Don, largely pasture and cultivated<br />
land. There is also the estuarine environment of the Don River in which<br />
the complex mud flats habitat are subject to tidal flow which combines<br />
both river and sea life. The Reserve is predominately woodland<br />
vegetation covering a series of ancient marine terraces created in<br />
earlier times by rising and falling sea-levels. The area is unique as<br />
several distinctive environments merge.<br />
The Don River historic rail line also runs north / south through the<br />
Reserve with its depot located at the southern end.<br />
Recommendation;<br />
It is recommended that further reviews incorporate the western<br />
riparian area of the Don estuary. This area shares similarity in<br />
vegetation and provision of recreational facilities such as the<br />
Waverley Road walking track and is connected to the Reserve by<br />
the pedestrian Sawdust Bridge. Expanding an <strong>environmental</strong><br />
<strong>management</strong> <strong>plan</strong> to take in the riparian vegetation of the entire<br />
estuary would be a positive move in catchment <strong>management</strong>.<br />
1.3 Background<br />
Investigations have revealed no previous reports concerning the Don<br />
Reserve however the following provide a general context;<br />
v Kelcey Tier Green Belt Landscape Management Plan, 1992,<br />
Jerry de Gryse investigated the hills environment overlooking<br />
<strong>Devonport</strong> and made the observation that “Of necessity it was<br />
deemed important to find means of linking the Greenbelt to<br />
other natural areas (to p<strong>reserve</strong> natural values), other public<br />
recreation areas, and the greater population of <strong>Devonport</strong>”;<br />
v Mersey Bluff Management Plan, 1998, Gerner Consulting<br />
Group Pty Ltd & Associates, identified and assessed the<br />
physical, natural and cultural values of the Mersey Bluff area<br />
and described landscape and environment values of the Bluff;<br />
v Don Rivercare Plan and Initial Works Plan, 2002, Armstrong<br />
Agricultural Services Pty Ltd assessed the Don catchment and<br />
stated <strong>environmental</strong> priorities and works to rehabilitate the river<br />
and associated riparian vegetation. The Don Estuary was<br />
identified as having one of the highest priorities for<br />
<strong>environmental</strong> works.<br />
The Tasmanian Arts Council, on behalf of <strong>Devonport</strong> Council, produced<br />
a report, “Cultural Planning Consultancy Paper, 1994”, which
Don Reserve Environmental Management Plan<br />
Page 7 of 56<br />
highlighted the importance of the Don Reserve, Victoria Parade and the<br />
Bluff as “enhancements to the city’s physical appearance”.<br />
This <strong>plan</strong> accords with the intent of the state government’s Tasmanian<br />
Natural Resource Management Framework (2002), which recognises<br />
the need for integrated <strong>management</strong> of Tasmania’s natural resources.<br />
Success of Natural Heritage Trust funding for the rehabilitation of the<br />
Don Reserve together with the creation of two new Council positions of<br />
Environmental Planner & Bushland Coordinator illustrates <strong>Devonport</strong><br />
<strong>City</strong> Council’s recent commitment to effective natural resource<br />
<strong>management</strong>.<br />

3.0 Reserve Vision and Objectives<br />
It is intended that this <strong>plan</strong> strategically integrate Council, stakeholders<br />
and the community in protecting the health and biodiversity of the Don<br />
Reserve whilst acknowledging the urban context and associated<br />
recreational uses. The <strong>plan</strong> also provides a framework for both council<br />
works programs and volunteers.<br />
The <strong>plan</strong> provides <strong>environmental</strong> <strong>management</strong> controls and requires<br />
ongoing assessments, recommend on ground works, continued<br />
monitoring and public reassessment of this <strong>management</strong> <strong>plan</strong>. It is<br />
equally important that interpretation signage & brochures as well as<br />
<strong>environmental</strong> education be promoted.<br />
VISION STATEMENT<br />
The Don Reserve showcases how remnant bush can coexist with<br />
suburban <strong>Devonport</strong> and still maintain a healthy and diverse<br />
ecosystem.<br />
Biodiversity is p<strong>reserve</strong>d by promoting the importance of flora<br />
and fauna corridors between the coast and inland areas such as<br />
the Kelcey Tier Greenbelt.<br />
Significant vegetation communities and associated animal life<br />
exist within the Reserve of a state and or commonwealth<br />
importance and consequently require effective protection of the<br />
remnant ecosystem.<br />
<strong>Devonport</strong> Council’s intention for a Garden <strong>City</strong> is largely<br />
dependent on its unique natural environment such as the Don<br />
Reserve. Bushland is an important resource both in an<br />
<strong>environmental</strong> and recreational sense.
Don Reserve Environmental Management Plan<br />
Page 11 of 56<br />
Undertake identification and protection of Aboriginal sites &<br />
values.<br />
As an important remnant of indigenous vegetation the natural<br />
habitat of the Don Reserve defines who we are as Tasmanians and<br />
equally provides visitors to our state with a Tasmanian<br />
experience.<br />
The Don Reserve provides an educational & hands on experience<br />
in <strong>environmental</strong> <strong>management</strong> practices to residents, students<br />
and visitors. Local educational establishments such as The Don<br />
College & Nixon Street Primary School can readily access and<br />
experience the natural environment in a practical manner.<br />
Short Term Objectives<br />
Establish and continually support local community interests such as<br />
Friends of Don Reserve bushland group.<br />
Native animals are to be protected by enhancing indigenous vegetation<br />
and limiting impacts from cats and dogs. The habitat of the swift parrot<br />
and eastern barred bandicoot is to be enhanced.<br />
The protection of significant <strong>environmental</strong> values associated with<br />
remnant indigenous vegetation and animals.<br />
Control and eradicate weed species in conjunction with the Department<br />
of Primary Industries, Water & Environment and Bushcare Tasmania.<br />
This is to be in conjunction with revegetation using local provenance<br />
(indigenous) species.<br />
Prioritise and remove exotic <strong>plan</strong>ts (inc. non-indigenous natives)<br />
dependent upon weed risks and potential detrimental impacts on<br />
indigenous <strong>plan</strong>ts and ecosystems.<br />
Stabilise damaged areas by encouraging natural regeneration using<br />
existing brush matting and / or re<strong>plan</strong>ting with indigenous flora.<br />
Promote <strong>environmental</strong> awareness through interpretative signage<br />
based upon an established theme such as forest types.<br />
Emphasise the need for <strong>management</strong> and conservation of an urban<br />
bush <strong>reserve</strong> which also provides recreational opportunities.<br />
Long Term Objectives
Don Reserve Environmental Management Plan<br />
Page 12 of 56<br />
Encourage stewardship by promoting community involvement in Don<br />
Reserve activities and reviews of <strong>management</strong> <strong>plan</strong>.<br />
Maintain and enhance flora & fauna diversity and allow the natural<br />
ecosystem to function with minimal human intervention. Protect the<br />
habitat of fauna dependent upon mature black gum and white gum<br />
forest communities and in particular threatened fauna such as the swift<br />
parrot and eastern barred bandicoot.<br />
Protect and enhance the water quality of the Don River Estuary.<br />
Conserve sites of cultural significance.<br />
Reduce the impact of events such as fire and storm by providing<br />
maintenance and rehabilitation procedures as deemed appropriate.<br />
Wildfires may be lessened by effective maintenance procedures such<br />
as low intensity controlled burns where appropriate and undertake<br />
awareness campaigns.<br />
Provide opportunities for sustainable recreation and eco-tourism<br />
activities and continue to promote the values of the nature <strong>reserve</strong> to<br />
residents & visitors.<br />
Provide a working example of bush rehabilitation with educational /<br />
interpretative promotions of the <strong>environmental</strong> assets of the area<br />
including recognition of the value of remnant bush habitat.<br />
Showcase the ability of a remnant bush and recreational activities to be<br />
managed in a cooperative manner without detriment to the health of the<br />
ecosystem.<br />
Highlight the <strong>environmental</strong> values of the Reserve as promoting<br />
appropriate regional natural resource <strong>management</strong>.<br />
Continue volunteer co-<strong>management</strong> of the <strong>reserve</strong> with “Friends of Don<br />
Reserve” and encourage further community involvement.<br />
Eradication or control of weeds species where practical.<br />
4.0 Environmental<br />
The natural values of the area are largely based upon the remnant<br />
natural ecological communities. The Reserve remains in relatively good<br />
health with significant remnant vegetation and faunal communities<br />
given the natural values have been altered by nearby urban<br />
development (Fitzgerald, 2002, Bushcare). Report from Bushcare<br />
confirms that the Don Reserve has a high conservation value and<br />
consequently high priority for protection and conservation <strong>management</strong><br />
on a local, state and bio-regional scale.
Don Reserve Environmental Management Plan<br />
Page 13 of 56<br />
Remnant areas of black gum, white gum and swamp paperbark<br />
illustrate past vegetation types along North West Tasmania’s coastline.<br />
Clearing for agricultural use and urban expansion in the region together<br />
with ongoing degradation has occurred due to apathy and ignorance of<br />
the values of remnant bush. Vegetation clearance for walkers or<br />
service requirements, if unregulated, provides locations for weed<br />
infestations, damage to indigenous <strong>plan</strong>ts and soil erosion.<br />
The habitat value of remnant bush is enhanced if it is linked or is close<br />
to other patches of bush. Enhancement of bush in surrounding areas,<br />
either public or private owned, can function as a nature corridor or a<br />
buffer between bush and urban development.<br />
Aims:<br />
v To p<strong>reserve</strong> & protect existing bushland and to enhance<br />
biodiversity.<br />
v Obtain expert assistance from Bushcare, Parks & Wildlife,<br />
the Threatened Species Unit and the Department of<br />
Primary Industry, Water and the Environment.<br />
v Encourage stakeholders and property owners adjacent to<br />
the Reserve to maintain their native vegetation and<br />
progressively remove exotic weed species.<br />
v Encourage local stewardship and responsibility of an<br />
individual’s action on a public <strong>reserve</strong> by involving<br />
community members.<br />
v Maintain links to neighbouring bush <strong>reserve</strong>s as a nature<br />
corridor.<br />
4.1 Water Quality<br />
The Don Reserve is situated on the banks of the Don Estuary and<br />
functions as an <strong>environmental</strong> buffer between the estuary and urban<br />
development.<br />
Various streams flowing through the Reserve have suffered with water<br />
impurities through urban stormwater discharges and loss of streamside<br />
(riparian) vegetation. Likewise there is evidence of land forms<br />
associated with past lagoons / wetlands which have been drained due<br />
to urban development. Consequently the natural filtration associated<br />
with wetlands has been compromised as urban stormwater is piped<br />
directly into the Don estuary.
Don Reserve Environmental Management Plan<br />
Page 14 of 56<br />
Stormwater and wastewater must not prejudice the achievement of the<br />
water quality objectives as established under the State Policy as<br />
established under the State Policy on Water Quality Management<br />
1997.<br />
Actions:<br />
v Investigate the feasibility of re-establishing wetlands at<br />
the northern end of the Reserve adjacent to The Don<br />
College Oval with appropriate flood mitigation controls.<br />
v Stormwater to be drained to prevent erosion or pollution<br />
of existing surface, ground and river / coastal waters.<br />
v Rehabilitate degraded stream banks flowing through the<br />
Don Reserve.<br />
v Establish water testing points, in conjunction with<br />
Waterwatch, to monitor the health of stream water and<br />
undertake appropriate investigations and remedial work.<br />
v Minimise adverse impacts on existing drainage patterns<br />
with particular note of black gum & swamp paperbark<br />
forests. Establish a works procedure.<br />
4.2 Flora and Vegetation<br />
The Don Reserve has conservation significance as it supports the<br />
largest single patch of black gum forest (Eucalyptus ovata) along the<br />
north coast of Tasmania (Richard Barnes, 2001). Shrubby black gum<br />
forest and coastal white gum forest are threatened species under the<br />
Tasmanian Regional Forest Agreement. These forest types have been<br />
extensively cleared with less than 2% remaining.<br />
A botanical survey recording native and exotic flora in the <strong>reserve</strong> was<br />
undertaken in late 2001 and early January 2002 by Bushcare<br />
(Fitzgerald 2002) and members of the Australian Plant Society. One<br />
hundred and sixty-four <strong>plan</strong>t species were recorded during the surveys.<br />
Of these, 4 are endemic to Tasmania, and 43 introduced. Many of the<br />
introduced <strong>plan</strong>ts are recognised as <strong>environmental</strong> weeds (capable of<br />
invading and degrading native vegetation). A few additional exotic<br />
pasture species associated with areas of garden, lawn and playing<br />
fields were not recorded. A full list of <strong>plan</strong>t species in the Reserve<br />
as of January 2002 is given in appendix 1.<br />
The following provides a summary of the vegetation communities<br />
identified by Bushcare;<br />
v Eucalyptus viminalis (white gum) coastal shrubby forest occurs<br />
at the northern end of the <strong>reserve</strong> adjacent to The Don College
Don Reserve Environmental Management Plan<br />
Page 15 of 56<br />
Oval with a narrow strip extending south beside the railway line<br />
and is considered to be in good condition. Within the local<br />
Flinders bioregion the conservation status of coastal white gum<br />
forest is considered rare and is given the highest level of<br />
conservation priority for <strong>plan</strong>t communities (category 1,<br />
CARSAG 2000). There are very few patches of this<br />
vegetation type remaining on the north coast.<br />
v Eucalyptus ovata (black gum) and sedgey / shrubby forest is<br />
the dominant vegetation community within the Reserve. Much of<br />
the central area of the Reserve south of The Don College is<br />
dominated by this vegetation type. Most of the Eucalyptus ovata<br />
forest is intact and healthy; however there are localised weed<br />
infestations. The condition of this community ranges from poor<br />
to excellent. Black gum forest is of very high conservation<br />
value throughout Tasmania. In this bioregion it is under<strong>reserve</strong>d<br />
and is considered endangered (category 1, CARSAG<br />
2000).<br />
v Melaleuca ericifolia (swamp paperbark) forest is located<br />
generally on the mud flats at the edges of the estuary,<br />
particularly at the southern end of the <strong>reserve</strong>. Black gums are<br />
present at some sites, which represent a transition between pure<br />
stands of swamp paperbark and black gum forest with swamp<br />
paperbark understorey. In this local bioregion swamp paperbark<br />
forest is considered rare and is given a high level of<br />
conservation priority (category 2, CARSAG 2000).<br />
v Eucalyptus amygdalina (black peppermint) occupies the drier<br />
parts of the Reserve located on higher ground along the estuary<br />
and slopes near Steele Street & the aquatic centre. Coastal<br />
black peppermint forest is widespread and well <strong>reserve</strong>d and<br />
therefore has relatively low conservation significance<br />
(category 1, CARSAG 2000). However all areas of native<br />
vegetation are important and should be conserved adding<br />
significant diversity of habitats and species to the <strong>reserve</strong>.<br />
v Damp sclerophyll forest is typically dominated by a mixture of<br />
eucalypt species and is often transitional between wet and dry<br />
forest types. Only a relatively small area occupying a drainage<br />
line near the cricket ground exists in the southern part of the<br />
Reserve. In this bioregion damp sclerophyll forest is considered<br />
rare and depleted from its former extent and is given a very<br />
high level of conservation priority (category 1, CARSAG<br />
2000).<br />
v Acacia sophorae shrubland (coast wattle) is typical of coastal<br />
sandy soils and occurs as small isolated patches at the northern<br />
extreme of the Reserve. The condition is poor with patches
Don Reserve Environmental Management Plan<br />
Page 16 of 56<br />
infested with blackberry and other weeds. The conservation<br />
value of sand dune vegetation (including A. sophorae) is a high<br />
priority non-forest community (TVMS Scientific Reference<br />
Group 2000).<br />
v Small patches of Austrostipa stipoides, coastal spear grass<br />
saltmarsh, have been mapped on the more elevated mudflats.<br />
Larger areas are to be found in the adjacent estuary outside the<br />
area of this <strong>plan</strong>. The general condition is good and such<br />
Graminoid saltmarsh is a high priority non-forest community<br />
(TVMS Scientific Reference Group 2000).<br />
v Areas of exotic parkland including introduced trees / shrubs<br />
and grasses exist especially near the aquatic centre. A row of<br />
exotic trees & non indigenous shrubs occurs along the sealed<br />
walking track between the two creeks near the southern end of<br />

Objectives – Flora and Vegetation;<br />
Protect, maintain and monitor natural flora diversity. Of high importance<br />
is the protection and enhancement of black gum forest for its own<br />
endangered status and as a significant feeding source for the<br />
threatened swift parrot. Protect and enhance the black gum forest<br />
community with emphasis on the requirements of the swift parrot and<br />
the habitat of Black eyed Susan (Tetratheca ciliata) which is listed as<br />
rare in Tasmania.<br />
Promote natural revegetation assisted with <strong>plan</strong>tings propagated from<br />
seed and other <strong>plan</strong>t materials (local provenance) from the locality.
Don Reserve Environmental Management Plan<br />
Page 17 of 56<br />
This protects and promotes the local gene pool and is considered best<br />
practice for revegetation.<br />
Maintenance practices should not adversely prevent natural seeding of<br />
native vegetation.<br />
Actions:<br />
v Improve community awareness by distributing leaflets promoting<br />
“a good bushland neighbour’ theme ie the benefits of<br />
indigenous <strong>plan</strong>ts and the hazards of weed infestations.<br />
v Establish photo points to monitor changes over time assessing<br />
the success of <strong>environmental</strong> works within the Reserve.<br />
v Investigations into surface drainage to consider whether to<br />
continue or enhance "ponding" of surface waters or to increase<br />
the provision of drains in low lying areas where the hydrology<br />
has been modified.<br />
v Identification of threatened species habitat and preventative<br />
<strong>management</strong> strategies to minimise impact upon <strong>plan</strong>ts by<br />
rehabilitating existing areas. Identify areas especially close to<br />
walking tracks and undertake rehabilitation works.<br />
v Deter the removal of fire wood and paperbark saplings unless<br />
approved. Priority is to be given to retaining natural habitat.<br />
v Investigate legislation / legal controls such as conservation<br />
covenants and Land for Wildlife program to protect<br />
<strong>environmental</strong> values.<br />
v Some weed species including blackberries may be providing<br />
habitat for native animals consequently their removal should be<br />
gradual and replaced with indigenous <strong>plan</strong>ts or pruning / trash.<br />
As recommended in the following Fauna survey.<br />
v Prepare a weeds <strong>management</strong> strategy in consultation with<br />
Bushcare and Department of Primary Industries, Water & the<br />
Environment (DPIWE). A resultant weed control <strong>plan</strong> would<br />
describe the botanical values of the area and the actions and<br />
strategies needed to control weeds or exotic species.

4.3 Fauna<br />
A fauna survey, by RD&M consultants was undertaken in late May<br />
2002 which included observation, local information and live trapping<br />
(Lists of animals previously seen and recorded in survey are included<br />
in Appendix 2). The faunal consultants did comment on the<br />
unseasonal weather conditions having an impact on the survey<br />
however follow-up surveys during the project period in 2002 did provide<br />
additional invertebrate information. This clearly highlights the need for<br />
additional surveys over a number of years and seasons to provide a<br />
more detailed picture.<br />
This survey confirmed there is little evidence of invasion of the Reserve<br />
by introduced fauna further supporting the Bushcare assessment that<br />
the Reserve is largely intact and representative of the diversity of native<br />
and modified vegetation habitats.<br />
A total of nine mammal species were recorded in the Reserve including<br />
echidna, eastern barred bandicoot, southern brown bandicoot, brushtailed<br />
possum, ring-tailed possum, long-nosed potoroo, Tasmanian<br />
pademelon, Bennett’s wallaby (uncommon) and swamp rat.<br />
The report also identified the likely existence of the water rat and a<br />
further 4 species, the sugar glider, eastern and little pygmy possums<br />
and white-footed dunnart, and 8 bat species may also occur in the<br />
Reserve. In total, 10 species of mammal are either known or very likely<br />
to occur in the Reserve, and there are a further 12 species which may<br />
occur in the Reserve. This represents a substantial proportion (65%) of<br />
the state’s total mammal fauna i.e. 34 species that are known or likely<br />
to be present within a relatively small area. Refer to Table 3 Appendix<br />
2 which provides list of native mammal species recorded or deemed<br />
likely to occur.<br />
Particular note is made of the eastern barred bandicoot which the<br />
commonwealth lists as vulnerable given its decline on the mainland.<br />
Consequently habitat preservation is important to this mammal’s<br />
ongoing existence. Refer to Tables 7 & 8, Appendix 2 which provides<br />
lists of fauna species of conservation significance in the Reserve and<br />
recorded within 5 kilometres. The fauna survey noted that the Reserve<br />
supports a diversity of bird species whilst lacking raptors. Sixty-five<br />
species were recorded including the noteworthy swift parrot and<br />
masked owl both of which are threatened species. Refer to Table 4,<br />
Appendix 2 for a full list of native bird species.<br />
The significance of the black gum forest in providing a valuable feeding<br />
source to the swift parrot was also reinforced. It should also be noted<br />
that DPIWE has produced a Swift Parrot Recovery Plan, 2001 which<br />
emphasises the listing as endangered under the Commonwealth<br />
Environment Protection and Biodiversity Conservation Act 1995 and<br />
endangered under schedule 3 of the Tasmanian Threatened Species
Don Reserve Environmental Management Plan<br />
Page 20 of 56<br />
Protection Act 1995. The swift parrot population is estimated at being<br />
less than 2,500 mature individuals and that a decline in numbers is<br />
projected unless action is taken to address the threats to the species. It<br />
is recommended that efforts be undertaken to support the recovery<br />
<strong>plan</strong> as deemed appropriate in the Don Reserve. In essence this would<br />
mean preserving and enhancing the black gum forest community ie its<br />
feeding source.<br />
The report from RD&M made particular reference to the presence of<br />
feral cats and uncontrolled domestic cats and dogs within the Reserve<br />
in posing a significant threat to the viability of populations of small<br />
ground dwelling mammals such as bandicoots, potoroos and reptiles in<br />
the Reserve. The major times of concern were during periods of weed /<br />
vegetation removal. It was recommended that a program to control /<br />
eliminate feral cats from the Reserve be implemented and the use of<br />
the Reserve by uncontrolled domestic pets, cats and dogs, be<br />
prohibited. The preservation of suitable habitat is the single most<br />
important requirement for maintaining healthy mammal populations<br />
within the Reserve. The isolation of the Reserve located between the<br />
urban areas of <strong>Devonport</strong> and cleared pastureland on the western side<br />
of the Don River gives this patch of remnant native habitat added<br />
importance. A significant bottleneck and obstacle to mammal dispersal<br />
exists at the southern end of the Reserve. The Reserve is separated<br />
from native vegetation on ‘Kelcey Tier’ by developed land, Stony Rise<br />
Road and the Bass Highway. Given the small size of the Reserve, even<br />
small, incremental incursions into the remaining native vegetation may<br />
further impact on mammal populations.<br />
Objectives:<br />
Protection of significant fauna with particular note of the swift parrot,<br />
eastern barred bandicoot and masked owls and associated flora values<br />
of the Reserve.<br />
Restoration of natural values of the Reserve that have become<br />
damaged and/or degraded.<br />
Maintenance of modified areas of the Reserve such as parkland and<br />
railway lines free of significant <strong>environmental</strong> weeds.<br />
Control or eradication of significant <strong>environmental</strong> weeds within the<br />
natural areas of the Reserve.<br />
Mitigation of off-<strong>reserve</strong> threats to the natural values of the Reserve.<br />
Actions:<br />
v Minimise clearing and modification of existing native vegetation.
Don Reserve Environmental Management Plan<br />
Page 21 of 56<br />
v Maintain fallen logs & forest debris with due consideration of fire<br />
safety.<br />
v Clearing, even small, incremental incursions into the remaining<br />
native vegetation should be strictly avoided.<br />
v Undertake the requirements under the Swift Parrot Recovery<br />
Plan 2001 in protecting and managing the habitat of swift<br />
parrots.<br />
Weeds and Exotic Vegetation<br />
Environmental weeds generally impact upon native flora and fauna<br />
habitat by displacing local <strong>plan</strong>t species which may reduce the<br />
availability of suitable habitat and/or food. Conversely <strong>environmental</strong><br />
weeds can enhance habitat conditions for both native and introduced<br />
pest animals in the short term by providing shelter and foods. In<br />
particular the dense cover of blackberry and gorse adjacent to open<br />
grassland areas would be beneficial to many native fauna, particularly<br />
species such as the eastern barred bandicoot, brown bandicoot, longnosed<br />
potoroo, Tasmanian pademelon and Bennett’s wallaby. However<br />
“in the present case, it is clearly possible to remove all blackberry and<br />
other woody <strong>environmental</strong> weeds without major detriment to the native<br />
mammal fauna” (RD&M 2002).This is largely due to the availability of<br />
areas of tall grasses at the edges of mowed areas and in particular<br />
beneath boobyalla Acacia sophorae and other native shrubs.<br />
Especially in the short term during weed eradication such areas should<br />
be maintained. The indigenous understorey of sword sedges<br />
Lepidosperma spp. and sagg Lomandra longifolia in the native forest<br />
habitat, particularly in black gum forest provides native cover.<br />
Numerous areas of open exotic grassland occur in the Reserve,<br />
particularly in the north alongside the railway line, adjacent to the<br />
aquatic centre, and in the area known as the ‘basin’. This grassland,<br />
although exotic, provides important feeding areas for several species,<br />
particularly the vulnerable eastern barred bandicoot, the Tasmanian<br />
pademelon and Bennett’s wallaby.<br />
Actions:<br />
v Retain major sources of cover for mammals including tall<br />
grasses on verges and ensure grassy and sedgy ground covers<br />
are retained while removing <strong>environmental</strong> weeds such as<br />
blackberry and gorse.<br />
v Open areas of exotic grassland should be retained, together with<br />
the thick cover of native sedges and exotic grasses growing<br />
adjacent to these areas.<br />
Recreation
Don Reserve Environmental Management Plan<br />
Page 22 of 56<br />
Dogs are common in the Reserve, both leashed and unleashed and<br />
both domestic and feral cats are also likely to be present in significant<br />
numbers. Cats are known to prey on native mammals, and to have<br />
been responsible for declines in the abundance of mammal species on<br />
mainland Australia. Similarly, dogs take native mammals, and will<br />
chase and harass large species without necessarily killing prey. The<br />
precise impact of this predation and harassment on mammal<br />
populations is not known. However, it is clear that a high diversity of<br />
native mammal species have survived in the Reserve despite the<br />
presence of cats and dogs. This may in part be due to the refuge<br />
provided from marauding cats and dogs by the thick ground cover<br />
across the Reserve. Maintenance of this cover is therefore considered<br />
imperative for the long-term survival and coexistence of native<br />
mammals with cats, dogs and people within the Reserve.<br />
Although the mammal fauna of the Reserve has so far co-existed with<br />
cats and dogs, additional ways of managing these exotic predatory<br />
species will have a beneficial impact on the native fauna. Shooting<br />
and/or trapping and removal of feral cats would reduce predation<br />
pressure in the Reserve. The imposition of night curfews on domestic<br />
cats, though publicly unpalatable, would also benefit native species.<br />
Similarly, restricting dogs to leashes at all times within the Reserve<br />
would reduce the incidence of dogs harassing native wildlife.<br />
Actions:<br />
v Allow low impact recreation activities including walking, exercise,<br />
nature observation and pet walking for the protection of native<br />
fauna and vegetation.<br />
v The number of walking tracks through the native vegetation of<br />
the Reserve should be minimised and tracks should be well<br />
defined and constructed.<br />
v Domestic dogs should be controlled by leash at all times within<br />
the Reserve. Appropriate signage to be displayed.<br />
v A promotional campaign to be undertaken highlighting the<br />
negative impact that domestic cats have on native animals.<br />
v A trapping program within the Reserve should be undertaken to<br />
eliminate feral cats and to determine the effectiveness of<br />
domestic cat control measures by local residents.<br />
Invertebrate Fauna<br />
Although only a small number of invertebrate species were detected<br />
during the initial fauna survey the maintenance of the structural<br />
diversity of the vegetation of the Reserve will help achieve the ongoing<br />
survival of native insects etc. Invertebrate animals live in small spaces<br />
and most have narrow ecological niches. Providing the maximum
Don Reserve Environmental Management Plan<br />
Page 23 of 56<br />
variation in the shape and structure of the habitat as well as<br />
maintaining the native <strong>plan</strong>t species diversity is important. Variations in<br />
the amount of sunshine that reaches the ground, the availability of<br />
moist microhabitats, the shelter provided by individual grass tussocks<br />
and areas of bare ground at a small scale can produce important<br />
habitat for small animals (RD&M, 2002).<br />
There is little evidence of invasion of the Reserve by introduced<br />
species (RD&M, 2002) however two species of pill bugs, Polchellio<br />
scabrer and Armalidium vulgare were identified. These species are<br />
considered to be good indicators of <strong>environmental</strong> degradation. The<br />
fact that they were found in high numbers in surrounding gardens and<br />
only in low numbers on the disturbed fringes of the Reserve suggests<br />
that the Reserve is in reasonable ecological condition.<br />
Similarly the removal of fallen timber of all sizes may remove habitat for<br />
many species. There is a progression of invertebrates that cause the<br />
decomposition of fallen wood or standing dead trees. In fact more<br />
species may come and go in succession during the time between the<br />
death of a tree and its disintegration into the soil than have lived in it<br />
when it was healthy and alive (RD&M 2002). Areas that retain their<br />
natural vegetation in general, and which are relatively unmodified,<br />
possess a diversity of invertebrate animals that exceeds that of the<br />
surrounding modified areas by many times.<br />
There was no evidence of burrowing crayfish, Engaeus sp., and it is<br />
unlikely the Reserve could be naturally recolonised as urban<br />
developments provide barriers to dispersal. (RD&M 2002)<br />
There is little knowledge of the life requirements of the animals<br />
documented from the Don River Reserve. In the absence of specific<br />
information the safest course of action is to treat the areas under<br />
consideration as small sub units and to decrease the possibility of local<br />
extinctions by providing the greatest variety of possible habitat (RD&M<br />
2002). One of the richest sources of animals collected during the<br />
survey was the interior and underside of logs and sticks. In time the<br />
removal of fire wood can result in a time gap in the presence of various<br />
types of habitat. Firewood gathering can be very thorough in this regard<br />
and although it is generally not a major problem in the Reserve, it<br />
should generally be treated with some caution in smaller areas.<br />
Management of remnants for maintenance of invertebrate diversity and<br />
ecological function are therefore dependent on several simple<br />
principles:<br />
· The maintenance of the native vegetation with maximum<br />
diversity in all its forms, diversity of species, diversity of<br />
vegetation structure, diversity of physical structure<br />
· The treatment of areas as sub units rather than as uniform<br />
wholes
Don Reserve Environmental Management Plan<br />
Page 24 of 56<br />
· The prevention of invasion by introduced species, particularly<br />
those that can survive in an unmodified natural environment.<br />
Introduced Fauna<br />
Two species of invertebrates present in the Reserve and which<br />
constitute a potential threat to its <strong>environmental</strong> wellbeing are the<br />
honey bee Apis mellifera and the European wasp Vespula germanica.<br />
The honey bee colonises hollows and can exclude species of birds and<br />
mammals that require these spaces to live and breed in. European<br />
wasps are aggressive predators which can deplete local populations of<br />
native invertebrates. Further they can also cause problems for<br />
predatory birds as they have a vicious sting which may prove<br />
debilitating or fatal to small animals and birds which mistake them for<br />
tasty and less harmful natives of a similar size or colour.<br />
Actions:<br />
v Destroy European wasp nests detected in the <strong>reserve</strong>.<br />
v Remove or destroy nests of honey bees detected in the <strong>reserve</strong>.<br />
The following relate generally to the preservation / enhancement of<br />
birds, animals and insects in the <strong>reserve</strong>.<br />
v Ongoing fauna surveys over a number of seasons and years to<br />
fill gaps in knowledge for ongoing <strong>management</strong> and protection.<br />
Community involvement is suggested in consultation with such<br />
organisations as Field Naturalist Groups, Birds Australia and the<br />
Gould League.<br />
v Maintain and enhance flora habitat for vulnerable or endangered<br />
fauna. Investigate options for artificial nesting boxes and<br />
preservation of hollowed trees if not deemed to be a public risk.<br />
Such hollowed trees provide habitat for a range of fauna<br />
including parrots, owls, bats etc. Fallen trees also provide for<br />
quolls, Tasmanian devils, snakes and lizards.<br />
v Educate community volunteers and visitors to the <strong>reserve</strong> about<br />
animals particularly threatened species so as to minimise<br />
impacts of weed control programs and recreation activities on<br />
the animals.<br />
4.4 Geology<br />
Processes related to sea level changes are responsible for much of the<br />
local landforms (physical geography related to geomorphology) and as<br />
a result alluvium and beach deposits exist along the eastern bank of<br />
the Don Estuary. The geology of this area is complex and diverse<br />
however several distinct units can be identified with Jurassic dolerite<br />
and Kelcey Tier Mudstone and Sandstone horizons in the Don Reserve
Don Reserve Environmental Management Plan<br />
Page 25 of 56<br />
(Geological information – Tasmanian Department of Resources and<br />
Energy 1990)<br />
Eric Nash a former geology teacher at Don Secondary College has<br />
provided the following information;<br />
“Shingle deposits in the Reserve are erratics and have been<br />
transported during earlier floods of melt water or strong river flow (large<br />
shingle deposits occur at the Tasmanian Arboretum)”. [approximately<br />
15 Kilometres from <strong>Devonport</strong> CBD]<br />
“On the banks of the Don River below the stand of E. amygdalina<br />
(these trees are located on a well drained sandy loam river terrace)<br />
dolerite outcrops and large boulders are resting on Permian-Triassic<br />
sandstone. This sandstone is also found as outcrop on the top car<br />
park of The Don College. Sea level changes are responsible for much<br />
of the physiography of the Reserve and the old shoreline (Holocene) 5<br />
to 6 ft above present sea level is dated at approximately 6000 to 7000<br />
years with much evidence of depositional features eg low sand dunes<br />
and shingle. The oval at Don College is underlain with 2ft of pure white<br />
sand and the old shoreline is evident near the College entrance in<br />
Watkinson Street.<br />
The lagoon north of the oval is a typical Tasmanian feature found<br />
behind dunes.<br />
The Don College design relates to the stepped nature of the site as the<br />
marine levels below merge with the upper Pleistocene beach deposits<br />
on which <strong>Devonport</strong> is built. – Eric Nash, 2002 (former Geology<br />
Teacher – Don College)”<br />
This information provides an introduction into landforms and soil types<br />
formed in the past which directly influence present day vegetation types<br />
and animal life. The natural geomorphic complexity in a river system<br />
also provides the building blocks for habitat diversity and is therefore<br />
an indicator of river health.<br />
The Don Rivercare Plan 2002 provides detailed descriptions of the Don<br />
River and tributaries and specific actions for high priority places<br />
throughout the catchment. The Don Estuary is described as a tidal area<br />
of 3.3 kilometres in length and the <strong>plan</strong> attributes the highest reach<br />
priority “1 conservation” and confirms the estuary as an asset to be<br />
protected. The report states “The eastern shore of the estuary supports<br />
very high priority forest: predominately shrubby black gum forest.<br />
Although this area is in reasonable condition and <strong>reserve</strong>d, disturbance<br />
through inappropriate public usage and natural disturbance such as<br />
wind storms have resulted in subsequent weed invasion. The small<br />
remnants on the western shore are a high priority for protection as is<br />
rehabilitation of the riparian zone to link these remnants. Works needed
Don Reserve Environmental Management Plan<br />
Page 26 of 56<br />
to retain their value should be the first priority for public funding”.<br />
(Armstrong Agricultural Services & Ecosynthesis, 2002)<br />
Actions:<br />
v Obtain further appropriate geomorphologic information.<br />
v Work towards a whole of estuary <strong>management</strong> strategy<br />
4.5 Protection<br />
4.5.1 Weed <strong>management</strong><br />
A weed <strong>management</strong> study is has been undertaken involving<br />
Department of Primary Industries, Water and Environment (DPIWE).<br />
See Appendix 3, Managing Weeds. Neighbouring land owners,<br />
stakeholders and volunteers are to be encouraged to participate in<br />
<strong>management</strong> programs involving the control and eradication of weeds.<br />
Existing introduced <strong>plan</strong>ts may be maintained and appropriately<br />
managed if the <strong>plan</strong>t is deemed not to be intrusive on the indigenous<br />
<strong>plan</strong>t communities passing weed risk assessment guidelines. State<br />
weed <strong>management</strong> <strong>plan</strong>s are currently being prepared by DPIWE that<br />
will identify the measures required to control or eradicate declared<br />
weeds.<br />
The most vulnerable areas identified are those at which disturbances<br />
have occurred either natural or human and include;<br />
v the northern end adjacent to Coles Beach Foreshore Reserve;<br />
v adjacent to high use areas including aquatic centre, residential<br />
properties and The Don College<br />
v edges of the Reserve including tracks;<br />
v storm damaged;<br />
v the Don River historic railway line; and<br />
v non-indigenous native and exotic <strong>plan</strong>ts especially in the<br />
southern area including pine trees such as Pinus radiata.<br />
Rehabilitation of these areas using indigenous <strong>plan</strong>ts (local<br />
provenance) is deemed to be of a high priority given the invasiveness<br />
of weed species and decline of native species.<br />
It is also imperative to maintain those areas that are currently weed<br />
free. This must be implemented in conjunction with the revegetation<br />
with local provenance native species.
Don Reserve Environmental Management Plan<br />
Page 27 of 56<br />
Figure 7 Coastal paperbark forest, northern end of Don Reserve with invasive<br />
blackberry in the foreground<br />
The <strong>reserve</strong> contains bridal creeper (Asparagus asparagoides) listed<br />
nationally as one of the top twenty weeds of national significance<br />
(Weeds of National Significance - WONS) posing a serious threat to<br />
bushland conservation and currently under a national eradication<br />
program. The seeds are predominantly spread by birds, and the <strong>plan</strong>t<br />
should be given the highest priority for control.<br />
Actions:<br />
v Use an integrated approach to weed control i.e. using a<br />
combination of control methods which will depend upon the<br />
nature of the infestation, location and resources available (see<br />
Appendix 3– Managing Weeds).<br />
v Prioritise weed species based on current status in Reserve,<br />
invasive characteristics, ecological impact and risk assessment.<br />
Other weed species will be prioritised based on <strong>plan</strong>t<br />
characteristics such as dispersal mechanisms, seed longevity<br />
and genetic contamination of the indigenous flora. Bridal<br />
creeper, gorse, broom and cotoneaster as highest priorities<br />
for <strong>management</strong> within the <strong>reserve</strong>.<br />
v Weed <strong>management</strong> be integrated with the protection of natural<br />
and cultural values, erosion control and revegetation works;<br />
v Undertake Weed mapping and ongoing monitoring.<br />
v Seek funding for weed <strong>management</strong> as a high priority.<br />
v Produce leaflets promoting a good bushland neighbour<br />
philosophy including minimising garden <strong>plan</strong>t escapees.

Page 28 of 56<br />
4.5.2 Fire Management<br />
The Don Reserve is located within the Barrington Fire Management<br />
area. The draft Fire Control Plan 2001 by Tasmanian Fire Service for<br />
the abovementioned area identifies the Don River Reserve as an area<br />
of major bush fire risk.<br />
The close proximity of houses, Don River Railway workshops &<br />
infrastructure, <strong>Devonport</strong> Aquatic Centre and Council’s parks depot<br />
require a fire <strong>management</strong> <strong>plan</strong> to be integrated into the overall<br />
<strong>environmental</strong> <strong>management</strong> <strong>plan</strong>. Investigations are to be undertaken<br />
to summarise assets and desired <strong>environmental</strong> values, as identified in<br />
the Bushcare reports, which are to be protected from fire. Any<br />
subsequent fire reduction measures are to be undertaken with respect<br />
to the <strong>environmental</strong> values attributed to native flora and fauna whilst<br />
maintaining a safe environment for fire-fighters and visitors / nearby<br />
residents.<br />
Uncontrolled fire presents a real threat to the native mammal fauna as<br />
the Reserve represents a largely isolated patch of native habitat. If the<br />
entire Reserve were to burn, the majority of the mammal fauna would<br />
be destroyed and re-colonisation from unburned habitat would be<br />
difficult for most species. Fire <strong>management</strong> should therefore aim to<br />
prevent any large, hot burns within the Reserve.<br />
Fire is not generally necessary to manage the fauna or flora habitat of<br />
the Reserve within the foreseeable future as identified by the flora and<br />
fauna reports. In the absence of fire the forest communities will<br />
progress to an old growth condition and provide additional habitat and<br />
niches for native vertebrate and invertebrate fauna. Hollow<br />
development and senescence of eucalypt canopy trees will provide<br />
habitat for a number of hollow dependant animal species. Litter and<br />
rotten logs will provide additional habitat on the ground for<br />
invertebrates, frogs and reptiles.<br />
A collaborative approach is to be undertaken identifying key<br />
stakeholder responsibilities and is to involve input from Council and<br />
Tasmania Fire Services. Equally visitors and nearby residents have a<br />
responsibility to ensure proper fire safety practices.<br />
Actions:<br />
v A fire <strong>management</strong> <strong>plan</strong> is to be created taking into account both<br />
appropriate hazard reduction, where appropriate, and nature<br />
conservation. Tasmania Fire Services is to be involved.<br />
v Undertake appropriate fire safety promotion to visitors and<br />
nearby residents.
Don Reserve Environmental Management Plan<br />
Page 29 of 56<br />
v Review current effectiveness of fire tracks / fire breaks and aim<br />
for efficient multiuse of such infrastructure where applicable.<br />
v Maintain fire tracks and ensure appropriate access.<br />
v Manage understorey growth with respect to surveyed vegetation<br />
communities within the Reserve and fauna habitat values<br />
identified in section 4.3.<br />
v No burning of swamp bark and damp sclerophyll forest unless<br />
deemed appropriate by Bushland Coordinator and / or Bushcare<br />
technical officer.<br />
v Fire frequency should be maintained by patch burning in<br />
accordance with a fire <strong>management</strong> <strong>plan</strong>.<br />
v Approval to burn is to be obtained from appropriate authority i.e.<br />
Tasmania Fire Service with burns targeted for autumn.<br />
v After fires monitoring is to be <strong>don</strong>e to assess need for weed<br />
control / rehabilitation works.<br />
5.0 Management of Human Use<br />
5.1 Introduction<br />
The Reserve exists within the context of an urban environment as<br />
shown by the number of recreational activities and adjacent urban<br />
uses. Appropriate human activities are to be encouraged but managed<br />
to reduce adverse impact upon the conservation values of the Reserve.<br />
5.2 Aboriginal Heritage Study<br />
An aboriginal heritage survey was undertaken in 2001 with consultation<br />
with the local aboriginal community. The study identified that “the<br />
Aboriginal (Palawa) language group of Northern area was known as<br />
Pirinapel or Paranaple, prior to the European arrival, of the land that is<br />
known as <strong>Devonport</strong> these days, the Aboriginal name for Tasmania<br />
was Trouwerner.<br />
Two sites of potential aboriginal significance have been identified on<br />
the banks / within the river outside area of the project proposal and that<br />
there may be relics along the river edge. “The study states that this is<br />
irrelevant to the weed eradication program as the sites are outside the<br />
area of the project proposal.” The recommendations of the Aboriginal<br />
Study, October 2001 by Vernon Graham, aboriginal heritage<br />
consultant, were as follows:<br />
v That there is a buffer of 20 metres around any site/s located.
Don Reserve Environmental Management Plan<br />
Page 30 of 56<br />
v That in the area of any Aboriginal heritage site/s located and or<br />
situated, weeds be cut and paste and no ground disturbance.<br />
v That any <strong>plan</strong>ting of native Flora be <strong>plan</strong>ted outside of Aboriginal<br />
heritage site/s located and in the area were there is heritage let<br />
it rehab naturally.<br />
v If there is any further weed eradication the <strong>Devonport</strong> <strong>City</strong><br />
Council liaise with Tasmanian Aboriginal Land Council and or<br />
Aboriginal Heritage Officer.<br />
v In relation to any further weed control project the council refer to<br />
aforementioned recommendation.<br />
v That the <strong>Devonport</strong> <strong>City</strong> Council in relation to weed<br />
<strong>management</strong> project liaise with the Tasmanian Aboriginal Land<br />
Council.<br />
It is considered important to consult with the aboriginal community on<br />
the <strong>management</strong>, interpretation and protection of identified aboriginal<br />
sites. Highlighting aboriginal values including the use of <strong>plan</strong>ts as bush<br />
tucker / medicines and other issues concerning the bushland are to be<br />
encouraged.<br />
Actions:<br />
v Consult with the aboriginal community on the <strong>management</strong> of<br />
Aboriginal heritage.<br />
v Monitor Aboriginal sites for, and protect them from, damage.<br />
v Abide by the recommendations of the Aboriginal Survey by<br />
Vernon Graham dated October 2001<br />
v Report all Aboriginal sites discovered in the <strong>reserve</strong> to<br />
appropriate authority as required under the Aboriginal Relics Act<br />
1975.<br />
5.3 Historic Heritage<br />
A major part of the Don Reserve includes The Don College, a senior<br />
secondary college, which was established in November 1976. The<br />
stepped geography of the college’s site is a feature that was taken into<br />
consideration in the original <strong>plan</strong>s for the college buildings. Eric Nash,<br />
teacher, stated that “… students and I have <strong>plan</strong>ned the environs of the<br />
college which adjoins the Don Reserve to blend in with a natural<br />
bushland setting” (Wolfe S., Pillar to Post). There has been a concerted<br />
ongoing effort by the college staff to maintain a native landscape.
Don Reserve Environmental Management Plan<br />
Page 31 of 56<br />
Little historic information concerning the Don Reserve was found as<br />
compared to the extensive history of the western bank of the Don<br />
Estuary. Faye Gardam, local historian, has compiled two publications,<br />
the first a diary of a early settler in “Immense Enjoyment” and a broader<br />
historical publication “Sawdust, Sails and Sweat”. In the former there<br />
are numerous references by the writer between 1884 -1886 of crossing<br />
the “… the sawdust bridge ... to the bush on the other side of the river”<br />
with his family and observing birds, <strong>plan</strong>ts and animals in much the<br />
same way visitors presently experience the <strong>reserve</strong>. So whilst the<br />
western side of the Don Estuary was cleared for its timber and farming<br />
this did not occur to the same extent in the Don Reserve. In Sawdust,<br />
Sails and Sweat there are references to some development in the<br />
<strong>reserve</strong> with a track from the sawdust bridge, through what is now the<br />
pool area to Fenton’s Track as being the most direct way to travel,<br />
often on foot, between Don and Torquay (present day <strong>Devonport</strong>).<br />
There is also reference to a brick making kiln in the late 19 th century<br />
where the present Don Recreation Grounds exist. Limited farming did<br />
occur with some orchards and grazing as shown in figure 8, circa 1912.<br />
5.4 Recreational<br />
The Don Reserve Bush includes a number of recreational activities<br />
which coexist within the Reserve.<br />
<strong>Devonport</strong> Aquatic Centre<br />
The aquatic centre takes in swimming pools, supporting infrastructure<br />
such as car park, change rooms and <strong>plan</strong>t and associated open<br />
grassed areas fenced off from the Reserve. It is a major complex that<br />
provides recreational and health related activities for <strong>Devonport</strong>.<br />
Actions;<br />
v Any development associated with the complex is to have<br />
regard to and minimise impact upon the adjoining bushland.<br />
v Mitigate the operation of aquatic centre with particular note of<br />
discharge of treated water into / through the <strong>reserve</strong>.<br />
Cycle & Walking Track<br />
The walking / cycling track extends from the western port wharf through<br />
Victoria Parade, the Bluff, Coles Beach Reserve and onto the Don<br />
Reserve terminating on the western side of the Don River along<br />
Waverley Road, Don. Concerns were raised by fauna consultants on<br />
the potential impact of uncontrolled dogs being walked or let loose in<br />
the <strong>reserve</strong>. Given that the small, fragmented nature of the Reserve it<br />
is recommended that a precautionary approach be taken and<br />
accordingly require dogs to be on leash whilst in the Reserve.

Figure 8 Two photographs showing changes over 90 years - taken from Don Heads,<br />
<strong>Devonport</strong>, looking southwest<br />
The proliferation of tracks invites increased opportunities for vandalism<br />
and weed infestation. It is imperative that the existing track network is<br />
assessed as to usage and where deemed inappropriate closed and<br />
rehabilitated. This should be <strong>don</strong>e in conjunction with informative signs<br />
/ maps to highlight legitimate tracks and to educate visitors to remain<br />
on the designated tracks.
Don Reserve Environmental Management Plan<br />
Page 33 of 56<br />
Actions:<br />
v Introduce seating.<br />
v Investigate use of tracks. At completion of the survey<br />
consider each track and usage and whether appropriate<br />
for the Reserve. Disallow any activity not in keeping with<br />
the intent of this <strong>management</strong> <strong>plan</strong>.<br />
v Appropriate signage, walking track maps and leaflets is<br />
introduced highlighting designating tracks and<br />
emphasising the importance of not straying off these<br />
designated tracks.<br />
v Dogs are to be kept under leash.<br />
Figure 9 Recreational - Don River Railway crossing showing walking / bicycle track<br />
Fitness Track<br />
A fitness track, composed of sawdust, extends to the north of the<br />
aquatic centre running parallel to the Don River. The faunal report had<br />
concerns relating to potential impact of disease entering the Reserve in<br />
particular the root rot fungus Phytophthora cinnamomi. Root rot fungus<br />
and other <strong>plan</strong>t diseases have the capacity to impact not only on<br />
vegetation but also on the fauna of the Reserve through their impact on<br />
vegetation diversity. Don Reserve appears to be currently free of root<br />
rot fungus though susceptible species occur in the Reserve including<br />
the rare and potentially vulnerable blackeyed susan (Tetratheca ciliata).<br />
The use of sawdust as surface material for the fitness track needs to be<br />
monitored however the present stockpiling in the centre of the Reserve<br />
adjacent to the main walking track is considered visually inappropriate<br />
and potentially contaminating.<br />
Actions:
Don Reserve Environmental Management Plan<br />
Page 34 of 56<br />
v Earthworks and track construction proposed for the Reserve<br />
should take measures to reduce the potential for the introduction<br />
and spread of <strong>plan</strong>t diseases and weeds in the Reserve.<br />
v Relocate the stock pile of sawdust or receive and distribute as<br />
required. The present stock pile area is to be rehabilitated.<br />
Monitor pathogens within the sawdust material and aim for<br />
eventual fazing out of this material.<br />
Development and Works<br />
There are various council services within the Reserve such as sewer<br />
and stormwater main pipelines and the aquatic & parks depot. It is<br />
acknowledged that such infrastructure is of public value, however<br />
appropriate <strong>plan</strong>ning and rehabilitation works are to be undertaken to<br />
minimise impact upon the native vegetation. Priority is to be given to<br />
collocation of services and uses.<br />
Actions;<br />
v All works, including maintenance, which alters or disturbs the<br />
native habitat within the Reserve, is to be assessed for<br />
<strong>environmental</strong> harm. Procedural <strong>plan</strong>s are to be implemented<br />
based on best practice to minimise disturbance to the vegetation<br />
and rehabilitate with appropriate native vegetation.<br />
v Undertake appropriate soil conservation and erosion control<br />
procedures to prevent soil loss / siltation into creeks & Estuary.<br />
v Maintain existing drainage patterns or aim to minimise impact<br />
from hydrological changes particularly on swamp paperbark and<br />
black gum forest communities.<br />
5.5 Tourism<br />
<strong>Devonport</strong> functions as the gateway for passenger & vehicle ferries and<br />
is therefore one of the key access points between Tasmania and the<br />
mainland. Bushland within close proximity of <strong>Devonport</strong>’s CBD is an<br />
important <strong>environmental</strong> resource and ecotourism asset. The Don<br />
River Historic Railway (operated by the Van Diemen Light Railway<br />
Society Inc.) is a significant tourism destination within the Reserve<br />
which benefits from the native bushland setting.<br />
The society operates steam and diesel powered trains between the<br />
Don Village and Coles Beach along 3.5 kilometres of 3 foot 6 inch<br />
gauge track. Ray Howe of the society stated “that the journey through<br />
the Don Reserve is an important part of the train journey (pers<br />
communication 2001). The society has produced a “Permanent Way<br />
Maintenance Procedure” manual which describes maintenance<br />
procedures on the track, formation and adjoining railway right of way to<br />
ensure the condition of the railway. The report requires inspection and
Don Reserve Environmental Management Plan<br />
Page 35 of 56<br />
maintenance of drainage channels crossing the tracks and appropriate<br />
action for a fire on the railway (includes vegetation clearance).<br />
Figure 10 Don River Railway train - northern end of Reserve adjacent Don<br />
College Oval showing remnant Coastal White Gum Forest<br />
There is a need to manage human use whilst conserving <strong>environmental</strong><br />
values and the impacts on native habitat. Consequently use of the<br />
Reserve is to be encouraged and relevant information concerning flora<br />
and fauna circulated to visitors and neighbours. The main focus is to be<br />
on responsible co-existence between visitors and the bushland<br />
environment.<br />
Actions:<br />
v Promote <strong>environmental</strong> awareness by distributing<br />
appropriate leaflets and tourist information highlighting<br />
the significance of remnant bush and associated<br />
<strong>environmental</strong> values.<br />
v Promote the Don Reserve as part of an overall network of<br />
bushland and associated walking tracks. Refer to<br />
Appendix 4 Walks in <strong>Devonport</strong> maps.<br />
v Increase <strong>environmental</strong> awareness by taking guided<br />
walks for adults and school students.<br />
5.6 Access & Tracks<br />
There is a need to minimise edge effects and fragmentation (Fitzgerald,<br />
Bushcare, 2002) which leads to degradation of native vegetation.<br />
Investigations are needed to assess the viability of existing tracks.<br />
There are also a number of access points mainly from the north near<br />
Coles Beach Road (& under the railway bridge), south from Forth<br />
Road, via sawdust bridge from the west, from the Aquatic Centre off
Don Reserve Environmental Management Plan<br />
Page 36 of 56<br />
Steele Street and east from Don College. There are also a number of<br />
informal tracks from the east off Surrey Street. The concern is the<br />
potential for disturbance to the bush vegetation and weeds infestation.<br />
The walking tracks together with appropriate access points and car<br />
park facilities are to be promoted to encourage appropriate usage. All<br />
new car parking areas are to be located outside the Reserve or on<br />
degraded land. All vehicle entry points are to have appropriate barriers<br />
put in place.<br />
Actions:<br />
v Rationalise access points and upgrade.<br />
v Appropriate barriers are to be placed to prevent<br />
unauthorised public vehicle access.<br />
v Track construction and maintenance should avoid or<br />
minimise disturbance to native vegetation, changes to<br />
drainage and introduction of weeds.<br />

5.6 1 Interpretation and Education<br />
The natural values of Don Reserve are highly significant and require<br />
protection and conservation <strong>management</strong>. Information highlighting<br />
these values should be directed to neighbouring landowners, visitors to<br />
the Reserve and general community. Equally such an asset should be
Don Reserve Environmental Management Plan<br />
Page 37 of 56<br />
promoted as a curriculum resource to schools and colleges in the area<br />
and for general community education.<br />
The Don Reserve has the potential to serve as a major educational<br />
resource in the study of <strong>environmental</strong> issues including natural<br />
resource <strong>management</strong>. Various supporting agencies and programs are<br />
available including Landcare, Rivercare, Bushcare and Waterwatch.<br />
Local schools including the Don College, St Brendan Shaw, Nixon<br />
Street Primary and <strong>Devonport</strong> Christian School are to be encouraged<br />
to include the Don Reserve as a case study for various curricula<br />
subjects including the environment, history and recreational studies.<br />
Educational education and training should also be directed towards<br />
stakeholders and those working within the Reserve.<br />
The responsibility of safeguarding the <strong>environmental</strong> values is<br />
important consequently appropriate signs should be erected including<br />
the control of dogs and preventing vandalism.<br />
There should be promotion of the ecotourism value of the Don<br />
Reserve.<br />
Interpretative signage should relate to a common theme to promote<br />
identifiable memory recall relating to the Don Reserve eg bush tucker,<br />
remnant bush, habitat of swift parrot. Introductory signs erected asking<br />
visitors to stay on designated paths.<br />
General signs indicating the status of the <strong>reserve</strong> and responsibilities /<br />
prohibitions eg cars and motor bikes should be upgraded and<br />
strategically placed. Advice is to be obtained from such organisations<br />
as Bush Watch – a Tasmanian Police strategy.<br />
Brochures are to be created and distributed to visitors explaining the<br />
conservation & recreation values and protection requirements of the<br />
<strong>reserve</strong>.<br />
Actions:<br />
v Develop opportunities for education and interpretation of the<br />
natural values to the <strong>Devonport</strong> community with emphasis on<br />
schools and colleges.<br />
v Provide informative signs at main entrances<br />
v Provide appropriate maps to show both the internal layout of the<br />
Reserve as well as how it is connected to the larger bushland<br />
network.<br />
v Ensure formal tracks are identified and appropriately used<br />
through signage.
Don Reserve Environmental Management Plan<br />
Page 38 of 56<br />
v Involve existing organisations in curbing vandalism such as<br />
Bushwatch and introduce appropriate signage to encourage<br />
community involvement.<br />
5.6.2 Community Awareness and Involvement<br />
Whilst the <strong>Devonport</strong> <strong>City</strong> Council has responsibility for the <strong>reserve</strong>,<br />
community advice and participation is essential for the long term<br />
success of rehabilitation works. A number of community groups,<br />
schools and organisations make regular use of the <strong>reserve</strong> as do local<br />
residents and visitors.<br />
Likewise it is important to establish and maintain a stakeholder group<br />
including representatives from Don River Historic Railway Group, Don<br />
College, Tasmanian Fire Service and <strong>Devonport</strong> <strong>City</strong> Council.<br />
Figure 12 First meeting in <strong>reserve</strong> of Friends of Don Reserve, 2001<br />
Actions:<br />
v Maintain support for Friends of Don Reserve group and<br />
continuing community involvement in <strong>reserve</strong><br />
<strong>management</strong> and maintenance.<br />
v Regularly liaise and develop good working relations with<br />
adjacent land owners and mangers on <strong>management</strong><br />
issues and projects of common interest.<br />
v Develop community appreciation of and support for<br />
environment values.

6.0 Implementation and Review<br />
<strong>Devonport</strong> <strong>City</strong> Council is the authority responsible for the <strong>management</strong><br />
of the Don Reserve. The community has a joint responsibility in<br />
advising and assisting Council in fulfilling that <strong>management</strong> role.<br />
It is recommended that further investigations be undertaken within the<br />
Don Estuary to provide appropriate estuarine <strong>management</strong> strategies.<br />
6.1 Monitoring and evaluation<br />
It is important to assess the effectiveness of <strong>management</strong> under this<br />
<strong>plan</strong> in achieving the desired <strong>management</strong> objectives.<br />
Monitoring methods may include photo point monitoring, wildlife counts,<br />
maintaining <strong>reserve</strong> clean up records as well as local resident,<br />
stakeholders and visitor comments. Monitoring reports are to be<br />
provided to <strong>Devonport</strong> <strong>City</strong> Council and to meetings of the Friends of<br />
Don Reserve.<br />
Further information obtained by monitoring is an effective means of<br />
reviewing the effectiveness of actions recommended in this <strong>plan</strong> and as<br />
conditions inevitably change.<br />
An appropriate monitoring system for the Reserve is to be<br />
implemented.<br />
Actions:<br />
v Map the extent of weeds in the Reserve and document weed<br />
control efforts.
Don Reserve Environmental Management Plan<br />
Page 40 of 56<br />
v Document revegetation techniques and survey revegetation<br />
works for species growth and survival rates<br />
v Undertake fauna surveys over various seasons and years.<br />
v Conduct site assessments of the health of each vegetation<br />
community<br />
v Monitor the effects of major disturbance events in the Reserve.<br />
v Involve community participation including Friends of Don<br />
Reserve and local schools in monitoring.<br />
6.2 Research<br />
It is considered that this <strong>plan</strong> is the starting point for further research on<br />
the natural values within the Don Reserve and <strong>Devonport</strong>. The fauna<br />
survey clearly indicated that a single survey will only provide a snap<br />
shot of what is evident in the Reserve at that particular time. Given that<br />
a number of animals are migratory and that both animals and <strong>plan</strong>ts<br />
may not be evident at a particular time (eg. orchids) it is considered<br />
appropriate to continue research in the Don Reserve. This ongoing<br />
information would also provide valuable information for ecological<br />
studies, natural history interpretation and natural resource<br />
<strong>management</strong>.<br />
Action:<br />
v There should be ongoing efforts to update flora and fauna<br />
species lists. Contacts should be made with such organisations<br />
as Birds Australia, the Gould League, University of Tasmania<br />
and local schools / community groups as possible means of<br />
undertaking ongoing studies.<br />
The <strong>management</strong> <strong>plan</strong> is to stay in effect for five years unless<br />
circumstances require prior revision. Amendments to this<br />
document to made after consultation with interest groups eg<br />
Friends of the Don Reserve.

GLOSSARY<br />
Biodiversity (biological diversity) means the variety of life forms: the<br />
different <strong>plan</strong>ts, animals and micro-organisms, the genes they contain, and<br />
the ecosystems they form. It is usually considered at four levels: genetic<br />
diversity, species diversity, ecosystem diversity and community diversity.<br />
Conservation means all the processes and actions of looking after a place so<br />
as to retain its significance, always including protection, maintenance and<br />
monitoring.<br />
Indigenous species means a species that occurs at a place within its<br />
historically known natural range and that forms part of the natural biodiversity<br />
of a place.<br />
Introduced species means a translocated or alien species occurring at a<br />
place outside its historically known natural range as a result of intentional or<br />
accidental dispersal by human activities.<br />
Natural integrity means the degree to which a natural system retains its<br />
condition and natural rate of change in terms of size, biodiversity and habitat.<br />
Natural landscape means large, relatively undisturbed area with topographic<br />
and catchment integrity where natural processes continue largely unmodified<br />
by human interventional.<br />
Natural Resource Management is the <strong>management</strong> of all activities that use,<br />
develop and/or conserve our air, water, land, <strong>plan</strong>ts, animals and microorganisms,<br />
and the systems they form.<br />
Protection means taking care of a place by maintenance and by managing<br />
impacts to ensure that significance is retained.<br />
Riparian zone refers to riverbanks further than two metres from an active<br />
channel that have typical riparian vegetation communities; floodplains; that<br />
are seldom flooded, or where only rising floods are experienced.<br />
Threatened species means a species listed in the Schedules of the<br />
Threatened Species Protection Act 1995

Don Reserve Environmental Management Plan<br />
Introduced Plants<br />
Page 53 of 56<br />
APPENDIX 3.0 MANAGING WEEDS<br />
Introduced <strong>plan</strong>t species are defined as all <strong>plan</strong>t species that occur outside<br />
the natural range of the species and includes native <strong>plan</strong>ts outside the<br />
immediate local area. Environmental weeds are a major concern to the<br />
community and land managers. Weeds are unwanted <strong>plan</strong>ts that are in the<br />
wrong place as they effectively compete with native vegetation for soil<br />
moisture, nutrients and light. They in fact reduce native seedling germination<br />
and survival. The result often sees a loss in biodiversity which weakens the<br />
integrity and health of the Reserve.<br />
However consideration needs to be given to introduced <strong>plan</strong>ts that may<br />
possess important historic or cultural significance. If conflicts occur between<br />
<strong>environmental</strong> and cultural aspects of a <strong>plan</strong>t then appropriate information and<br />
consultations are to be implemented prior to the removal of a <strong>plan</strong>t.<br />
WeedPlan, the Tasmanian Weed Management Strategy, establishes<br />
community ownership, mutual recognition and cooperation as the basis for a<br />
regional community based approach to weed <strong>management</strong> in Tasmania. The<br />
Weed Management Act 1999 supports this approach as seen by the<br />
progressive introduction of weed <strong>management</strong> <strong>plan</strong>s. Control strategies<br />
include the protection of areas free of <strong>environmental</strong> weed infestation,<br />
<strong>management</strong> of infested areas such as along roadsides, waterways and<br />
disturbed areas. High priority is to be given to the revegetation of affected<br />
areas once control of the <strong>environmental</strong> weed is verified.<br />
Weeds of significance in Don Reserve are as follows<br />
Botanical Name Common Name<br />
Rubus fruiticosa sp agg. Blackberry<br />
Coprosma repens Mirror Bush<br />
Cotoneaster spp. Cotoneaster<br />
Pittosporum undulatum Sweet Pittosporum<br />
Erica lusitanica Spanish Heath<br />
Crataegus monogyna Hawthorn<br />
Cytisus scoparius English Broom<br />
Ulex europaeus Gorse<br />
Rosa rubiginosa Brair Rose<br />
Genista monspessula Montpellier Broom<br />
Cordateria spp. Pampas Grasses<br />
Passiflora mollissima Banana Passion fruit<br />

Sollya heterophylla Bluebell creeper<br />
Hedera helix English Ivy<br />
Pinus Radiata Radiata Pine<br />
Asparagus asparagoides Bridal Creeper
Don Reserve Environmental Management Plan<br />
Priorities are to be given as follows;<br />
v Control of <strong>environmental</strong> weeds threatening biodiversity.<br />
v Control of <strong>environmental</strong> weeds not threatening biodiversity<br />
v Management of culturally significant introduced <strong>plan</strong>ts.<br />
Page 54 of 56<br />
Actions;<br />
v Management methods will utilise an integrated approach to<br />
weed control i.e. using a combination of control methods<br />
depending on the nature of the infestation, location and<br />
resources available. This would be based on maintaining natural<br />
ecosystem processes and minimising impacts such as soil<br />
disturbance.<br />
v Prioritisation and control of invasive weed species to be<br />
undertaken addressing <strong>plan</strong>t characteristics such as ecological<br />
impacts, methods of dispersal and seed longevity. Broom and<br />
gorse while having more localised seed dispersal will require<br />
ongoing control for a number of years due to the seed longevity,<br />
80 and 40 years respectively). Prevention of new seed banks<br />
developing would have a high priority. Pampas, blackberry,<br />
pittosporum, cotoneaster and mirror bush have a larger<br />
dispersal range due to the consumption of berries by birds or by<br />
other mechanisms such as wind and animal dispersal.<br />
v Non-indigenous <strong>plan</strong>t species such as Eucalypts and Acacias<br />
from other parts of Tasmania or mainland not endemic to the<br />
area to be removed. This would be undertaken to prevent<br />
hybridisation with the local flora thus protecting the genetics of<br />
the <strong>reserve</strong>.<br />
v Develop weed education programs to assist in the prevention of<br />
weed problems. The community would be encouraged to<br />
remove <strong>plan</strong>ts such as cotoneaster from gardens to prevent<br />
seed dispersal by birds into the <strong>reserve</strong>. The dumping of garden<br />
waste on the fringes of the <strong>reserve</strong> would also be discouraged.<br />
Such programs should involve both internal education and<br />
training workshops for the land manager, <strong>Devonport</strong> Council,<br />
stakeholders and to the general public.<br />
v A significant number of weed species in the <strong>reserve</strong> are garden<br />
escapes from the surrounding properties both from natural<br />
dispersal and the dumping of garden waste on the edges of the<br />
<strong>reserve</strong>. Educating and involving the community is an important<br />
step in preserving the health of the bush.
Don Reserve Environmental Management Plan<br />
Page 55 of 56<br />
The following illustrates the various control methods that may be used<br />
either singularly or in combinations;<br />
v hand pulling including use of mattocks and spades<br />
v mechanical through use of secateurs / pruning saws, chainsaws,<br />
tractors, grader blades, slashers when a large area is to be<br />
controlled. Reducing the mass will mean less time and money<br />
using chemical controls if required. Care must be taken to<br />
lessen soil disturbance and transfer of weed seed and<br />
pathogens into or out of the bushland area.<br />
v The use of herbicides in the Don Reserve should be<br />
appropriately managed with regard to selection and application.<br />
Appropriate advice on herbicide selection and suitability should<br />
be obtained from <strong>Devonport</strong> <strong>City</strong> Council Weed Officers or<br />
DPIWE Regional Weed Management Officers. Selection of<br />
herbicides should be based on toxicity and suitability with low<br />
toxicity and high LD 50 ratings being preferred. An off label<br />
permit has been obtained for the use of Metsulfuron-s-methyl<br />
(Brushkiller/Brushoff) effective for the control of many<br />
<strong>environmental</strong> weeds such as climbers and woody species. This<br />
product is not scheduled therefore having lesser safety<br />
requirements for application. Climbers and creepers may be<br />
pulled from native vegetation prior to chemical application to<br />
minimise off target damage.<br />
v Weed removal techniques such as cut and paint should be<br />
encouraged to reduce off target damage from herbicide<br />
application. Low toxicity herbicides such as Glyphosate bioactive<br />
may used effectively on many species. <strong>Devonport</strong> <strong>City</strong> Council<br />
Weeds Officer or Regional Weed Management Officers may be<br />
contacted for information on appropriate techniques.<br />
v Revegetation in accordance with appropriate techniques and<br />
species selection should be employed following weed removal.<br />
v Environmental control by eliminating excesses of nutrient runoff<br />
eg sewer overflows which would stimulate weed growth.<br />
v Biological control methods which are available for broom<br />
(Cytisus scoparius) and gorse (Ulex europeaus) the latter having<br />
been introduced into parts of the Reserve. These are<br />
strategically placed where eradication is not feasible in the short<br />
term and reduction of vigour and seed set is an advantage.<br />
v Education by informing the community of the harmful effects that<br />
weeds have on bush <strong>reserve</strong>s eg loss of biodiversity. Informing<br />
the public of the invasiveness of weeds especially of garden<br />
escapees.
