5.2      Fauna

        The faunal community identified onsite includes some 26 species of birds, five reptile
         species, six amphibian species, three mammals and two invertebrates.
        Both adult and juvenile specimens of the Endangered Swamp Crayfish
         (Tenuibranchiurus glypticus) were found in the acidic, tannin stained pools in areas
         of surface expression of groundwater in the potential Impact Area and 100m buffer.
         Due to knowledge gaps relating to Swamp Crayfish breeding habitat requirements,
         areas occupied by Swamp Crayfish are considered breeding habitat.
        There are three WildNET records of Koala in a one kilometre radius of the site and
         there is evidence of Koala activity in the Scribbly Gum woodland at the northern end
         along the fire trail (2012) and in the surrounding habitats (2017). The area proposed
         for the southern stormwater discharge drain contains 0.650 ha of mapped Koala
         habitat (core).
        Other arboreal mammals e.g. Gliders are also likely to occur and medium-sized
         mammals e.g. Bandicoots and Swamp Wallabies are considered likely to inhabit or
         traverse the survey area.
        The large populations of small mammals and frogs around the landfill, ponds and
         mulch piles support an active raptor and snake population.
        Targeted amphibian surveys confirmed the presence of a large population of
         Wallum Froglets within 200-600 metres of the landfill’s eastern boundary.
        Suitable habitat for breeding by Wallum Froglets (core habitat) occurs within the
         potential Impact Area, however no calling activity indicative of breeding was
         detected during the survey period in the Impact Area. Calling activity indicative of
         breeding by Wallum Froglet was detected in the site’s 100 metre buffer, with core
         breeding habitat (i.e. ponded areas with surface expression of acidic groundwater)
         confirmed at 200 to 600 metres east north-east of the landfill. Species utilisation of
         core breeding habitat areas may expand into the potential Impact Area under very
         wet conditions. Refer to Figure 15.
        There is also potential habitat for Wallum Rocketfrog in seasonally inundated
         depressions and ephemeral drainage lines throughout the closed heathland and
         wetland communities in the Potential Impact Area and 100 metre buffer.
        The habitat suitability models for these species suggest that all areas mapped as
         RE12.3.13 and 12.3.5 constitute core habitat. Adjacent vegetation communities (RE
         12.5.4) are considered non-core habitat for Wallum Froglets dispersing after
         breeding and core habitat for Wallum Rocketfrogs.
        Potential Habitat Models for Wallum Sedgefrog indicate that core habitat is not
         present in the Potential Impact Area. Non-core habitat is mapped as occurring in
         the areas mapped as 12.3.13 and 12.3.5. However, ground-truthing surveys
         suggest that an area of sedgeland located on the edge of the 100 metre buffer
         possesses suitable (core) habitat attributes to support breeding by this species.
