Appendix H - Biodiversity Code

                                                                                      Native Foresters



Within the wet sedgeland just east of the carpark, showers over the two day survey period
created ephemeral ponds (Figure 11) that supported surface activity of the Endangered Swamp
crayfish (Tenuibranchiurus glypticus). Further information on habitat use and communal burrows
created by the species is provided in Section 4.6.

Additional habitat structures on site were minimal. A small number of fallen logs, palm fronds
and piles of dumped garden waste provide some cover and habitat for small reptiles and litter
foraging invertebrates (Figure 12).

Proximity of the survey area to maintained roads, stormwater infrastructure and residential
housing is associated with undesirable recruitment of non-native flora and ornamental species.
The survey area would benefit from ongoing weed management. Measures to minimise weed
spread during works, particularly Singapore daisy (Sphagneticola trilobata), Groundsel
(Baccharis halmifolia) and exotic creepers and succulents, should be followed.

Table 5 provides an analysis of the potential presence of threatened species as listed in Wildlife
Online and the EPBC Protected Matters Search Tool or based on the field habitat suitability
assessment that may occur within the area (i.e. one kilometre radius) and comments on the
likelihood of those species occurring in or around the Carramar site.
