GENERAL COMMITTEE MEETING MINUTES                                                           14 JUNE 2021

   The biodiversity and ecosystem values of waterways, wetlands and adjacent riparian zones are
   protected by:
      a)  avoiding any new development ina riparian buffer area and wetland area;
      b)  retaining aquatic and terrestrial habitat in riparian zones;
      c)  maintaining and enhancing wildlife corridors and connectivity along watercourses and
          drainage lines for native fauna movement;
      d)  avoiding edge effects and damage from adjacent land uses;
      e)  maintaining stream integrity and bank stability by minimising bank erosion and slumping;
      f)  maintaining water quality through filtering sediments, nutrients and other pollutants; and
      g)  removing pest species and replacing them with local native species.

   As discussed above, from an aquatic ecosystem perspective, significant environmental improvement
   could be achieved by rehabilitating the zone bounded by the 4 m contour with canopy and
   understorey species which are known to occur in RE12.3.4 and by improving fluvial connectivity by
   installing low flow culvert/pipes in the bottom dam. Reinstatement of key habitat requirements of
   Crinia tinnula would also be desirable. From the western 4m contour to the rear boundary, roughly as
   shown in Figure 6, a rehabilitation objective to enhance koala habitat by planting canopy species with
   local provenance in RE 12.3.14a, including threatened Fucalyptus conglomerate, would be
   appropriate.  Full ecosystem rehabilitation over approximately 1.2 ha is probably an unreasonable
   requirement. However, establishing the fundamental components of the preclear ecosystems will
   allow for ecological succession to achieve greater species diversity and habitat function to occur over
   time considering the increased connectivity provided to the western remnant. Placing restrictions on
   fencing within an environmental covenant; and establishing a house site at the front of the new lot,
   as a condition of approval will also reduce any potential minor additional human impacts of what is
   currently a highly disturbed ecosystem.
