4.2.4 Amphibians

Despite a recent rain event no native amphibians were identified during survey, however given
the available components it is considered that the site may potentially support a low-moderate
assemblage of ground, sedge and tree frogs common to subcoastal environs (particularly
during wetter summer months).

WildNet data (refer APPENDIX 4) also indicates that four (4) species of threatened amphibian
have been previously recorded within the subregion (5-kilometre radius of the site). These
species, their conservation status and habitat requirements (Robinson, 2007) are as follows:

       Tusked Frog (Adelotus brevis) – scheduled as Vulnerable under NCA92. Prefers
        vegetated fringes of waterways within rainforest/wet sclerophyll environs.
       Wallum Froglet (Crinia tinnula) – scheduled as Vulnerable under NCA92. Prefers
        acidic, tannin-stained paperbark swamps in wallum country.
       Wallum Rocketfrog (Litoria freycineti) – scheduled as Vulnerable under NCA92.
        Prefers temporarily indundated swampy areas.
       Wallum Sedge Frog (Litoria olongburensis) – scheduled as Vulnerable under both
        NCA92 and EPBCA99. Prefers emergent vegetation within marshes/swamps
        associated with tannin-stained water.

A targeted search revealed no presence of these species at time of survey (wet weather
inclusive), and given the available components it is considered that the site does not comprise
core habitat therefore they are considered an unlikely occurrence during any season.

4.2.5 Reptiles

A negligible variety of native reptiles was identified during survey, however given the available
components it is considered that the site may potentially support a limited assemblage of
terrestrial/arboreal reptiles common to subcoastal environs (particularly during warmer summer
months).

Notwithstanding, WildNet data (refer APPENDIX 4) indicates that no species of threatened
reptile have been previously recorded within the subregion (5-kilometre radius of the site), and
given the available habitat components they are considered an unlikely occurrence during any
season.

4.3 Statutory Fauna Significance
4.3.1 Essential Habitat

The subject site is broadly designated on DNRMMRRD’s Vegetation Management Supporting
Map (refer FIGURE 8) as comprising ‘essential habitat’ potential for the following five (5)
species of threatened fauna under provisions of both the Vegetation Management Act 1999
and Nature Conservation Act 1992:

       593: Litoria olongburensis (Wallum Sedgefrog – Vulnerable)
       609: Litoria freycineti (Wallum Rocketfrog – Vulnerable)
       686: Crinia tinnula (Wallum Froglet – Vulnerable)
       860: Phascolarctos cinereus (Koala – Endangered)
       1867: Limosa lapponica baueri (Western Alaskan Bar-tailed Godwit – Vulnerable)

The proposal does not result in any direct/indirect clearing impacts to essential habitat,
therefore referral of the development application to DSDIP is not required.
