                          Ecological Assessment – Attunga Heights



6.2.5 Listed Ecological Communities
6.2.5.1 Significant Impact Criteria
An action is likely to have a significant impact on a critically endangered or endangered
ecological community if there is a real chance or possibility that it will:

      reduce the extent of an ecological community;
      fragment or increase fragmentation of an ecological community, for example by
       clearing vegetation for roads or transmission lines;
      adversely affect habitat critical to the survival of an ecological community;
      modify or destroy abiotic (non-living) factors (such as water, nutrients, or soil)
       necessary for an ecological community’s survival, including reduction of
       groundwater levels, or substantial alteration of surface water drainage patterns;
      cause a substantial change in the species composition of an occurrence of an
       ecological community, including causing a decline or loss of functionally important
       species, for example through regular burning or flora or fauna harvesting; or
      cause a substantial reduction in the quality or integrity of an occurrence of an
       ecological community, including, but not limited to:
            assisting invasive species, that are harmful to the listed ecological
              community, to become established; or
            causing regular mobilization of fertilisers, herbicides or other chemicals or
              pollutants into the ecological community which kill or inhibit the growth of
              species in the ecological community; or
            interfere with the recovery of an ecological community.


6.2.5.2 Site Assessment
Database searches revealed that two (2) threatened Ecological Communities are known to
occur within 5km of the subject site:

      Lowland Rainforest of Subtropical Australia – critically endangered; and
      Subtropical and Temperate Coastal Saltmarsh – vulnerable.

Neither of these communities are considered to occur on the site.


6.2.6 Listed Migratory Species On or Near the Site
6.2.6.1 Significant Impact Criteria
An action will require approval if the action has, will have, or is likely to have a
significant impact on a listed migratory species. Note that some migratory species are
also listed as threatened species. The significant impact criteria below are relevant to
migratory species that are not threatened.

An action is likely to have a significant impact on a migratory species if there is a real
chance or possibility that it will:
