                                                                                      Native Foresters



 ix.       Organic litter, fallen timber and rocks: Litter cover can be indicative of the degree of
           disturbance of a site, and can be an important determinant of species recruitment.
           It will influence soil microclimates, structure and composition, and provide refugia
           for invertebrates, reptiles, amphibians and ground dwelling mammals.
  x.       Recruitment: Recruitment of plant species, particularly woody perennials, within all
           strata reflects the site’s long-term viability.

 xi.       Landscape context: The size of a patch, its connectivity and distance to a core area
           of vegetation (i.e. greater than 50 hectares) can affect both its regenerative capacity
           and long-term viability. Species–area relationships suggest that large areas support
           more species and populations than smaller ones thus retaining greater genetic
           variability and providing refuge for species susceptible to disturbances.

For EVNT-listed species identified in Essential Habitat Mapping or WildNET within one
kilometre of the survey area, a likelihood of occurrence rating was assigned to each species
based on the following:

          Known - species positively recorded by this survey or other survey by qualified
           ecologists during past 30 years;
          Likely - based on the presence of suitable habitat and recent database records
           from study area or proximity;
          Possible - suitable habitat present for the species, but no recent database records
           from the study area or proximity; and
          Unlikely - based on a lack of suitable habitat and lack of proximate records.

2.2.4 Surface water - Groundwater interaction

A field survey was undertaken on the 26th April 2019 to further investigate potential impacts
of the proposed works on habitat for Swamp crayfish and ‘acid’ frog species along the
eastern edge of the landfill.

Field investigations focused on areas of wet heath and Melaleuca woodland (mapped as
RE 12.3.5 and 12.3.13) to the north-east and south-east of the tip. Data and observations
from this site visit were used to assess the following:

       a) The suitability of habitat for, and potential occurrence of, Swamp crayfish and ‘acid’
          frog species in proximity to proposed works during very wet conditions with localised
          flooding; and
       b) Existing hydrological conditions along and adjacent to the landfill boundary,
          including possible hydraulic connectivity between the tip and areas of
          known/potential Swamp crayfish and acid frog habitat.

During this site visit, information was gathered on:

          The extent of surface water flows originating from the landfill site;
          Water quality;
          Vegetation cover along and adjacent the eastern tip boundary; and
          Fauna present (crayfish, frogs and tadpoles).
