Vegetation clearing in non-rural NSW is governed by Chapter 2 of the State Environmental Planning Policy (Biodiversity and Conservation) 2021. The Chapter applies to all zones in Greater Sydney, Newcastle, and the other urban-zoned and environmental-zoned land outside rural NSW. It sets the rules for tree and vegetation removal that is not part of a development application.

The two-rule structure. Vegetation clearing is regulated under two parallel layers:

  1. Council DCP tree-permit rules. Each council’s Development Control Plan lists which tree species and dimensions require a permit before removal. Diameter at breast height, canopy spread, and protected species lists vary by council.
  2. Biodiversity Offsets Scheme (BOS) threshold. The SEPP imposes an entry threshold based on lot size and Biodiversity Values Map status. Clearing above the threshold triggers the BOS, which requires a BDAR (Biodiversity Development Assessment Report) prepared by an accredited assessor under the Biodiversity Assessment Method (BAM).

A council can only issue a tree-removal permit for clearing that is below the BOS threshold and outside the Biodiversity Values Map. Above the threshold, the application must go through the DA path, the BDAR must be prepared, and biodiversity offsets purchased or credited.

When clearing is part of a DA. If the vegetation removal is associated with a building application, the clearing rules apply through the consent authority’s biodiversity assessment under the DA, not under Chapter 2. The same BOS threshold logic applies, but the BDAR feeds into the DA rather than a separate permit pathway.

For builders. Vegetation clearing is often the silent risk in a redevelopment site:

  • Get the tree survey before quoting. A protected tree the client did not declare is the most common cause of post-quote cost increase.
  • Check the Biodiversity Values Map for the lot. Land mapped on it has a zero-clearing threshold for BOS entry.
  • For bushfire-prone sites, APZ (asset protection zone) requirements may force clearing that triggers the BOS. The APZ work and the BOS process must be sequenced together.

Other states. Each state has its own equivalent: VIC under the Planning and Environment Act 1987 and ResCode, QLD under the Vegetation Management Act 1999. The NSW two-rule structure (council permit + BOS threshold) is distinctive; check the relevant state regime before applying NSW logic elsewhere.

Also known as: tree removal, vegetation removal, native vegetation clearing.
