NSW Ecosystem Offset Trading Groups Regional Map

A regional-scale map of candidate non-threatened Ecosystem Offset Trading Groups for biodiversity offsetting across New South Wales. The map is derived from the NSW State Vegetation Type Map according to the Biodiversity Assessment Method and is updated annually. It includes key fields such as OFFSET_TRA (Offset Trading Group) and SUB_NAME_7 (Sub IBRA Bioregion).

Use Cases

• Analyze the spatial distribution of OFFSET_TRA groups across SUB_NAME_7 bioregions to identify potential offset trading zones.
• Integrate the OTGSUBIBRA concatenated field with property data to screen for regional-scale offset opportunities, excluding local decisions.
• Model vegetation class changes over time by comparing annual updates to the underlying State Vegetation Type Map.

Strengths

• Map covers the entire state of New South Wales, providing statewide spatial coverage.
• Data is updated annually in response to updates to the NSW State Vegetation Type Map.
• Derived from the authoritative NSW State Vegetation Type Map (SVTM vC2.0.M2.2) and the official Biodiversity Assessment Method.

Limitations

• Map is derived from regional-scale mapping and is explicitly not suitable for local or property-scale decisions.
• Does not include Offset Trading Groups for threatened ecological community (TEC) Ecosystem credit types.
• Does not indicate which Offset Trading Groups are currently in demand for the offset market.
