Review of Environmental FactorsGlenbrook commuter car park and interchange upgradediggings, scratches and scats, on and around trees. Opportunistic observations of fauna present at thestudy site during the survey were also recorded.Field guides and standard texts used as a reference are provided in the reference list. The naming ofspecies recorded or known for the region follows the nomenclature present in these texts. Theconservation significance of plants, animals and vegetation communities recorded is made with referenceto the Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act) and the ThreatenedSpecies Conservation Act 1995 (TSC Act).6.5.2 Existing environmentFloraNSW Wildlife Atlas database searches for threatened species listed on the TSC Act revealed 33 floraspecies previously recorded within a 10 km search radius, as well as 18 Endangered EcologicalCommunities (EECs) with potential to occur on site. The EPBC Act protected matters search tool revealedfive EECs likely to occur in the area and a total of 18 threatened flora species predicted to occur within a10 km radius of the Proposal site.The vegetation at the site varies depending on location from moderately good quality to highly degradedand weed‐infested. No threatened flora species were identified during the field survey. No vegetationfound on site was found to comply with the community description of any of the predicted EECs.The natural vegetation of the lower Blue Mountains at Glenbrook has developed on a dissected plateauof Hawkesbury Sandstone, with remnant Wianamatta Shale cappings persisting on some ridges. Thus thevegetation in the area surrounding Glenbrook Railway Station is generally part of the Sydney SandstoneComplex, with the potential for Ironbark Forest to occur on soils derived from Wianamatta Shales(Benson 1992). The vegetation community found on the site is derived from dry sclerophyll forest withsome remnant understorey vegetation remaining in areas and none in others. The community mostclosely matching the vegetation found in the more natural parts of the site is Sydney Sandstone RidgetopWoodland/Open Forest. Some higher quality areas outside the site boundaries are present which have agood overstorey component and a native shrub understorey.A comprehensive list of all flora species observed during the field investigations has been undertaken,with their cover abundance scores. A total of 80 flora species were identified during the survey. The list offlora species identified is provided in Appendix C. The study area has previously been extensivelydisturbed and exotic species have become dominant in cleared areas. A number of noxious weeds listedby Blue Mountains City Council were observed on‐site, including Broad‐leaf Privet (Ligustrum lucidum),Small‐leaved Privet (Ligustrum sinense), Lantana (Lantana camara), Blackberry (Rubus fruticosus), Senna(Senna pendula), Bridal Creeper (Asparagus asparagoides), Asparagus Fern (Asparagus aethiopicus), andCrofton Weed (Ageratina adenophora).The vegetation growing along the north‐eastern edge of the site, between Burfitt Parade and the railway,is in better condition than the cleared areas, with a good coverage of native trees and shrubs (includingAcacia parramattensis, Acacia longifolia, Acacia mearnsii, Omalanthus populifolius, Pittosporumundulatum, Syzygium australis, Cassinia sp., Hakea propinqua, and Bursaria spinosa), and a largely nativeunderstorey (Leucopogon muticus, Dianella caerulea, Geranium solanderi, Rumex brownii, Microlaenastipoides and Entolasia marginata). Shrubby weeds present in this area include Micky Mouse Plant(Ochna serrulata), Spearleaf swampmallow (Pavonia hastata), Lantana (Lantana camara), Senna (SennaRef No: 2260812 53
Review of Environmental FactorsGlenbrook commuter car park and interchange upgradependula), Paddy’s Lucerne (Sida rhombifolia), Blackberry Nightshade (Solanum nigrum), as well as exoticgroundcovers and climbers such as Goosegrass (Galium aparine), Wandering Jew (Tradescantiafluminensis), Moth Vine (Araujia sericifera), and Creeping Fig (Ficus pumila).The zone designated for the proposed commuter car park has been mostly cleared of native vegetation,with planted or weedy exotic trees (Jacaranda mimosifolia and Robinia pseudoacacia) as an overstoreyand a more or less exotic groundcover (Briza spp., Bromus sp., Ehrharta erecta, Lolium perenne, Cyperuseragrostis, Avena sp., Plantago sp., Euphorbia peplus, Anagallis arvensis, Conyza bonariensis, Hypochaerissp., and Lepidium africanum). There are, however, two species of native trees (Eucalyptus saligna andPittosporum undulatum) also present in this area.Habitat requirements and an assessment of the likelihood of presence for all threatened flora specieswere undertaken. Habitat assessments for all threatened species determined that the site providessuitable habitat for no threatened flora species, due to the heavily disturbed nature of the environment.However, higher quality vegetation on the western edge of the site (down slope) could provide imperfectbut suitable habitat for a number of threatened species, including Bynoe’s Wattle Acacia bynoeana,Dillwynia tenuifolia, Micromyrtus minutiflora, and Glandular Pink‐bell Tetratheca glandulosa. None ofthese species were observed during the survey either on‐site or within 10 m of the western boundary.FaunaDatabase searches identified 57 threatened species or subspecies potentially found in a 10 km radius ofthe site. Three of these species, as well as an additional 11 species, are listed as migratory under the EPBCAct and also potentially found in the 10 km radius. During the survey of the site, 11 native and two exoticbirds were observed or heard. No threatened fauna species were observed. The list of fauna speciesidentified is provided in Appendix C.The vegetation on‐site provides little in the way of habitat for vertebrate species, with very littlestructural complexity for small woodland birds. Some of the bigger eucalypts were flowering during thesurvey, with Rainbow Lorikeets (Trichoglossus haematodus) feeding in them. Other species observedduring the survey, such as Red Wattlebirds (Anthochaera carunculata), Sulphur‐crested Cockatoos(Cacatua galerita), Kookaburras (Dacelo novaeguineae), and Noisy Miners (Manorina melanocephala) arecommonly found in disturbed or urban areas, with the possible exception of the Green Catbird(Ailuroedus crassirostris), which is not as ubiquitous.The higher quality bushland to the west of the site was seen to contain a number of older trees (mainlyAngophora costata and Eucalyptus punctata), at least one of which had hollows large enough to supporteither mammals or birds. Nothing was seen entering or exiting the hollows during the survey, and nosigns of gliders feeding on the trees were observed. These trees are not designated for removal, butvegetation upslope would likely be altered to allow for the adjustment of the 11 KV overhead line.6.5.3 Potential ImpactsKey threatening processes most pertinent to the site works are:• the loss and degradation of native plant and animal habitat by invasion of escaped gardenplants, including aquatic plants• the clearing of native vegetation• bushrock removalRef No: 2260812 54
