Biodiversity Values Map

Transitional arrangements

In some areas of New South Wales commencement of the Biodiversity Offsets Scheme (including the Biodiversity Values Map) for local development has been delayed until 25 November 2018. See the transitional arrangements to find out when the Scheme applies to local development in your area.

The Biodiversity Values Map identifies land with high biodiversity value that is particularly sensitive to impacts from development and clearing. The map forms part of the Biodiversity Offsets Scheme Threshold which is one of the triggers for determining whether the Biodiversity Offset Scheme (BOS) applies to a clearing or development proposal. The map has been prepared by the Office of Environment and Heritage (OEH) under Part 7 of the Biodiversity Conservation Act 2016 (BC Act).

When is the Biodiversity Values Map used?

The Biodiversity Values Map is relevant to:

  • local developments (development under Part 4 of the Environmental Planning and Assessment Act 1979 which is not state significant development or state significant infrastructure) and,
  • clearing regulated by the State Environmental Planning Policy (Vegetation) 2017 (Vegetation SEPP).

If a relevant clearing or development proposal will have one of the following impacts in an area on the Biodiversity Values map then the Biodiversity Offsets Scheme applies:

How can I see the Biodiversity Values Map?

You can view the map through the Biodiversity Offsets Scheme Entry Threshold (BOSET) Tool.

The tool allows developers, landholders and consent authorities to determine whether proposed development or clearing triggers the Biodiversity Offset Scheme based on the Biodiversity Values Map. You can search for a location using an address or Lot and Deposited Plan (DP) number. The tool can produce a report that states whether the BOS threshold has been triggered based on the Biodiversity Values Map.

For more information you can read the User Guide (PDF 375KB) for this tool.

How can I find out the mapped values on a property?

Landholders, or their agents, can request an explanation report to show the biodiversity values that have been included on the Biodiversity Values Map for their property. Local councils or the Native Vegetation Panel can also request a biodiversity explanation report for a property for which they have received a development or clearing application.

To request an explanation report please contact us at or on 02 6360 9000.

What is included in the Biodiversity Values Map?

There are 11 types of land that may be included on the Biodiversity Values Map:

  1. Coastal wetlands and littoral rainforest as per the Coastal Management Act 2016
  2. Core koala habitat identified in a plan of management under State Environmental Planning Policy No. 44—Koala Habitat Protection (SEPP 44)
  3. Ramsar wetlands as defined by the Environmental Protection and Biodiversity Conservation Act 1999
  4. Land that contains threatened species or threatened ecological communities identified as potential serious and irreversible impacts (SAII) under Section 6.5 of the Biodiversity Conservation Act 2016
  5. Protected riparian land
  6. High conservation value grasslands or groundcover
  7. Old growth forest  
  8. Rainforest
  9. Declared areas of outstanding biodiversity value
  10. Council nominated areas with connectivity or threatened species habitat that the Environment Minister considers will conserve biodiversity at bioregional or State scale
  11. Any other land that in the opinion of the Environment Agency Head is of sufficient biodiversity value to be included.

These are set out in clause 7.3(3) of the Biodiversity Conservation Regulation 2017.

Does the Biodiversity Values Map overlap with the Native Vegetation Regulatory map?

Yes, there are overlaps between land included on the Biodiversity Values Map and the way land is categorised on the Native Vegetation Regulatory Map. However, the two maps have different purposes. You can find out more about the Native Vegetation Regulatory Map on the OEH website.

Updates to the Biodiversity Values Map

From time to time, OEH will update the Biodiversity Values Map to add or remove areas based on new information.

For 90 days after an amendment is made to the Biodiversity Values Map a proponent can choose whether to use the previous or new version of the map to determine whether a proposal will trigger the Biodiversity Offsets Scheme.

Map versions

The following table sets out the amendments that have been made to Biodiversity Values Map.

Date published


13 December 2017

Addition of mapping for:

  • the little penguin declared area of outstanding biodiversity value at Manly (referred to as critical habitat under the former Threatened Species Conservation Act 1995)
  • One threatened ecological community and four threatened species on land covered by the State Environmental Planning Policy (Kosciuszko National Park—Alpine Resorts) 2007.

Release of the original state-wide map

Local government nominations for additions to the Biodiversity Values Map

OEH expects to call for local government nominations for land to be included on the map. This will be communicated directly to local government.

The Minister for the Environment must be of the view that the nominated land will be of bioregional or state significance. The nominated land must also be approved by the Environment Agency Head.

At this stage there has been no call for nominations from local government.
