                              Dense Understorey/Ground Layers – provide cover for dispersal/refuge of smaller
                               terrestrial mammals; usually associated with intact sclerophyllous/riparian vegetation.
                               Marginal understorey/ground layer structure was noted predominantly adjacent to the
                               central northern boundary.
                              Outcrops/Cliffs/Caves – provide refuge for a variety of species; usually associated
                               with steep topography and variation in geological formations. No significant outcrops/
                               cliffs/caves were noted on the site.
                              Contiguous Vegetation – native bushland provides a dispersal conduit for fauna
                               between core habitats across the landscape. A minor level of connective function exists
                               within vegetation adjacent to the central northern boundary given that it is contiguous
                               with proximate bushland remnants to the north, however corridor value across the
                               majority of the site is otherwise considered to be limited given the landuse/disturbance
                               history and ongoing edge-effects throughout.

                     Given the available components it is considered that overall habitat value is Low-Moderate at
                     best, and concentrated predominantly within vegetation adjacent to the central northern
                     property boundary.

                     4.2.2 Mammals

                     A limited number of native mammals were observed directly/indirectly via trace during survey,
                     and given the available components it is considered that the site may potentially support a
                     minor assemblage of terrestrial/arboreal/flying mammals common to sub-coastal environs.

                     Notwithstanding, WildNet data (refer APPENDIX 4) indicates that two (2) species of threatened
                     mammal have been previously recorded within the subregion (5-kilometre radius of the site).

                     These species, their conservation status and habitat requirements (van Dyck & Strahan, 2008)
                     are as follows:

                              Grey-headed Flying-fox (Pteropus poliocephalus) – scheduled as Vulnerable under
                               EPBCA99. Prefers dense riparian vegetation for roosting and forages on nectar, fruits
                               and leaves.
                              Koala (SEQ bioregion Phascolarctos cinereus) – scheduled as Endangered under both
                               NCA92 and EPBCA99. Prefers sclerophyllous vegetation of varied composition and
                               structure comprising, among other Myrtaceous species, Forest Red Gum (Eucalyptus
                               tereticornis), Tallowwood (E. microcorys), Grey Gum (E. propinqua), Swamp
                               Mahogany (E. robusta) and Scribbly Gum (E. racemosa) for foraging/refuge.

                     A targeted search revealed no current/recent presence of these species at time of survey,
                     however given the available components it is considered that the site comprises some transient
                     habitat potential for both the Koala and Grey-headed Flying-fox within a broader home-range.

                     4.2.3 Birds

                     A minor abundance of native birds was observed during survey, and given the available
                     components it is considered that the site may potentially support a low-moderate assemblage
                     of raptors, nectivores, frugivores, insectivores, waders and edge-specialists common to
                     subcoastal environs (predominantly due to dispersal ability).

                     Notwithstanding, WildNet data (refer APPENDIX 4) indicates that eighteen (18) species of
                     threatened bird have been previously recorded within the subregion (5-kilometre radius of the
                     site). These species, their conservation status and habitat requirements (Pizzey & Knight, 2007)
                     are as follows:

                              Beach Stone-curlew (Esacus magnirostris) – scheduled as Vulnerable under NCA92.
                               Prefers open and undisturbed beaches, tidal mudflats/sandflats, mangroves and
                               exposed reefs.
