No threatened fauna species wereobserved: only common, generalist species typical of highly disturbed urban areas were recorded.Habitats at the site would have limited value for native fauna, given the degree of disturbance observedand lack of native vegetation.The aggressive Noisy Miner (Manorina melanocephala) was the most frequently observed andapparently dominant bird species at the site. Other species observed were typically large birds commonin urban gardens, such as the Sulphur-crested Cockatoo (Cacatua galerita), Rainbow Lorikeet(Trichoglossus haematodus), and Red Wattlebird (Anthochaera carunculata). Dense stands of exoticvegetation would have potential value as shelter habitat for small birds, but these stands are small andfragmented and would have limited value for most bird species given the observed presence ofaggressive species such as the Noisy Miner.Flooded areas of the site would support small numbers of common frog species such as the CommonEastern Froglet (Crinia signifera) and Striped Marsh Frog (Limnodynastes peronii), which were recordedduring the site visit. Eastern Water Skinks (Eulamprus quoyii) were also observed basking near theculvert outlets. The drainage line to the south of the site and flooded grassy areas would provide habitatfor these common, generalist frogs and reptiles and other such species able to persist in urbanenvironments. There is no habitat for any threatened frogs or aquatic fauna at the site.1.1.1 Conservation significanceIn summary, the site comprises highly disturbed vegetation with few habitat resources for native fauna,and is therefore considered to have low conservation significance. There is no vegetation at the sitewhich would correspond to any threatened ecological community, and it is considered highly unlikely thatany threatened flora species would occur. Four threatened fauna species and two migratory birds mayoccur at the site on an occasional or opportunistic basis, but would be highly unlikely to be dependent onhabitats at the site for their conservation in the locality.21/19721/1780114
