Yamba Bypass Species Impact Statement

Targeted ecological survey | Detailed reporting | Mapping


AWC prepared a Species Impact Statement (SIS) for Section 1 of the proposed Yamba Bypass. The SIS was completed to satisfy Director Generals Requirements (DGRs) and required detailed targeted survey for the Squirrel Glider and Grey-crowned Babbler. Following a full weeks survey for both species using call playback, arboreal trapping and spotlighting methods a detailed SIS including detailed habitat mapping was prepared examining the impacts of the Bypass on these species and detailing a number of mitigation measures.


  • Document available habitat and local populations of the Squirrel Glider and Grey-crowned Babbler
  • Fulfill Director Generals Requirements
  • Examine a range of mitigation options based on survey findings

Partners & Stakeholders

  • Clarence Valley Council


  • Submission of the SIS to the Department of Environment & Heritage (OEH); decision pending
  • Identification of a population of Squirrel Gliders within a fragmented peri-urban landscape
