Threatened Ecological Communities in Greater Sydney, 35 NSW-Listed Types

35 NSW-listed threatened ecological communities are mapped within Greater Sydney. The map is derived from best available mapping products and expert input, and it informs the Biodiversity Values Map, Native Vegetation Regulatory Map, Rural Fire Service 10/50 tool, and High Environmental Values Greater Sydney map. Mapping is updated frequently via expert input.

Use Cases

• Identify potential development constraints based on threatened ecological community locations.
• Inform conservation planning and priority-setting based on mapped community distributions.
• Support property-scale environmental assessments based on the spatial data.
• Cross-reference with other regulatory maps like the Biodiversity Values Map.

Strengths

• Map of 35 distinct threatened ecological communities.
• Derived from multiple best available mapping sources and expert input.
• Data informs several official regulatory and planning tools.
• Updated frequently via expert input.

Limitations

• Coverage is limited to Greater Sydney, with distribution beyond the study area not represented except for two communities.
