Ecological Assessment Process
Various factors play into the type of environmental/ecological/biodiversity assessment that your Development Application requires.
Development Applications involving the indirect or direct modification of native vegetation (including single tree removal, under scrubbing and vegetation clearing) will require one of two reports:
- Biodiversity Development Assessment Report (BDAR) – This report is required when the development proposal triggers the Biodiversity Offset Scheme (BOS). This occurs in one of three ways:
- The development is identified on the Biodiversity Values Map; or
- The development proposes the clearing or management of native vegetation exceeding the area clearing threshold set out by the Biodiversity Conservation Regulation 2017 (NSW); or
- If a 5-part test of significance concludes that the proposed development is likely to ‘significantly affect’ a threatened species or ecological community.
- Flora and Fauna Assessment (FFA) – This report is prepared where the proposed development does not trigger the Biodiversity Offset Scheme. This report will include any required 5-part Test (Assessment of Significance).

The FFA will also include any necessary assessments for threatened species or ecological communities specified in the Environmental Protection and Biodiversity Conservation Act 1999 (Cth).

Triggering the Biodiversity Offset Scheme
A Biodiversity Development Assessment Report (BDAR) can only be prepared by Department of Planning, Industry and Environment-accredited assessors. East Coast Ecology can prepare the necessary BDAR or FFA to accompany the Development Application.
