Flora & Fauna Survey & Ecological Assessments – 35 Water Street Wahroonga 4.4.2 Fauna Habitat Assessment Habitat types Modified environment: Comprises approximately half of the Subject Property and includes the buildings, driveways, footpaths, garden beds, cleared land, retaining walls and other built structures. The vegetation comprises a range of introduced landscape and horticultural species. The majority of these species have been planted over a period of many years, although there are a few remnant native species present. Previous arborist reports (Tree Wise Men 2007, 2011 and Landscape Matrix 2011) and observations in the field have indentified that only one (1) exotic tree in the modified environment is hollow bearing (this being a Liquidambar styraciflua). An ephemeral man-made drainage line runs along the western side of the driveway in the south-eastern section of the Subject Property. It is in poor condition and not considered to provide valuable resources to any native species. The native species supported by this habitat type are the typical urban-tolerant fauna species and the Subject Property provides no unique habitat essential to the survival of any of these species. Eucalypt Woodland: Occurs mainly within the eastern and southern section of the Subject Property. The canopy consists of mature eucalypt species while the understory is a mixture of native and exotic shrubs and groundcovers. Seven (7) native and one (1) exotic hollow bearing trees are present that are suitable for smaller hollow-dependant native animals. Wildlife Corridors and Vegetation Links Reviews of aerial photographs of the Region have identified areas of nearby bushland. The following areas (and their approximate distance from the Subject Property) have been identified (see Figure 4.1): Wahroonga Public School (100 metres north) – highly modified Blue Gum High Forest Turiban Reserve (250 metres north-east) Clive Evatt Reserve (440 metres north-east) Lovers Jump Creek (1 km east) Ku-ring-gai Chase National Park (>1 km north) The connectivity to these other areas of bushland is limited, with the exception of scattered native canopy species existing on nearby streets and in residential properties. The urban-tolerant species detected on the Subject Property are likely to have no difficulty traversing through these urban environments via the tree canopy, although this is discontinuous. The majority of the species detected within any large areas of bushland would not travel through urban environments to utilise the resources of the Subject Property.

A description of the likelihood of occurrence is given in Table 4.3. It also considers any potential impacts the Proposal may have on the said threatened species. Although only (1) threatened fauna species – the Powerful Owl (Ninox strenua) - was detected during the current field investigations, there are suitable resources available within the Subject Property to support a number of other threatened species. Accordingly, Assessments of Significance (commonly called the ‘Sevenpart Test’) have been prepared (see Section 4.5) for those species most likely to occur, being: • Powerful Owl (Ninox strenua) • Grey-headed Flying-fox (Pteropus poliocephalus) • Gang-gang Cockatoo (Callocephalon fimbriatum) UBM Ecological Consultants Pty Ltd Page 50
