Map of seven NSW listed Threatened Ecological Communties (TECs) within Illawarra, Shoalhaven and Southern Highlands. This dataset includes a subset of Serious and Irreversible Impact TECS including Robertson Basalt Tall Open Forest, Southern Highlands Shale Woodland, Mount Gibraltar Forest, Robertson Rainforest, Tableland Basalt Forest, Illawarra Lowlands Grassy Woodland and Melaleuca armillaris Tall Open Shrubland. The map is a compilation of three separate map products including "Melaleuca armillaris Tall Shrubland TEC condition mapping 2021", "Southern Highlands and Threatened Ecological Communities: Cross Tenure Operational Maps" and "Fine scale mapping of the threatened ecological community: Illawarra Lowlands Grassy Woodland in the Sydney Basin Bioregion".

This dataset only includes TECs that have been mapped to date. Limitations of this map include: not all SAII TECS within the defined area are included, (eg. Coastal Upland Swamps, Milton Ulladulla Rainforest, Illawarra Subtropical Rainforest and Shale Sandstone Transition Forest have not been mapped); some TECs are not completely mapped (eg. Tableland Basalt Forest); areas not identified as TEC may be TEC; areas identified as TEC may not be TEC; and areas identified as a TEC may be a different TEC. Accordingly, property scale assessments should inform activities, plans and proposals at the property scale.

Mapping is updated frequently via expert input. The map data informs the Biodiversity Values Map, Native Vegetation Regulatory Map and Rural Fire Service tools. We attempt to update the map to be consistent with other Regulatory Maps, however if there is inconsistency between this map and the Biodiversity Values Map, you can request a review: https://www.environment.nsw.gov.au/topics/animals-and-plants/biodiversity-offsets-scheme/clear-and-develop-land/biodiversity-values-map-and-threshold-tool/category-reports-and-map-review.
