Biodiversity assessment


Our senior ecologists are accredited by the NSW Government to undertake environmental assessments using the Biodiversity Assessment Method (BAM).

The BAM outlines how to assess impacts on biodiversity at development sites and stewardship sites. The BAM is a scientific document that provides:

  • a consistent method for the assessment of biodiversity on a proposed development or major project, or clearing site
  • guidance on how a proponent can avoid and minimise potential biodiversity impacts, and
  • the number and class of biodiversity credits that need to be offset to achieve a standard of ‘no net loss’ of biodiversity.

An accredited assessor must apply the BAM. The assessor documents the results of the biodiversity assessment in a Biodiversity Development Assessment Report (BDAR). The BDAR identifies:

  • how the proponent proposes to avoid and minimise impacts
  • any potential impact that could be characterised as serious and irreversible according to specified principles and
  • the offset obligation required to offset the likely biodiversity impacts of the development or clearing proposal, expressed in biodiversity credits.

A proponent must provide the BDAR to the approval authority as part of their development, major project proposal, or clearing application. A BDAR will be placed on public exhibition with the relevant development application.
