As of 05 May 2021 this map data has been superseded for operational use by Threatened Ecological Communities Greater Sydney. The CEEC product is no longer being maintained.

These map data contain a subset of NSW and Commonwealth listed Critically Endangered Ecological Communities (CEEC) within NSW. Version 6.0 (February 2020) contains minor adjustments to reflect change in NSW listing status of Sydney Turpentine-Ironbark Forest in the Sydney Basin Bioregion from EEC to CEEC. Version 1 only contained NSW CEECs. Further details regarding the updating of previous versions are provided under Lineage.

This composite map was derived from the extraction of relevant vegetation map units contained in a variety of existing vegetation maps held in the Office of Environment and Heritage (OEH) VIS (Vegetation Information System) Map Catalogue. Please note that not all Listed CEECs are currently represented in this dataset. Reasons include:

1. the CEEC has not yet been mapped;
2. the CEEC has been mapped but the source data are not yet openly available (see Supplemental Information for details).

Further CEECs may be added in future versions of this dataset.

Note, there is no formal process in place to guarantee correction in the source maps that are transferred to this composite map product.

Ecological communities are included in the critically endangered category of the Threatened Species Conservation Act, 1995, if they are facing an extremely high risk of extinction in NSW in the immediate future. Critically Endangered is also a category under the Environment Protection and Biodiversity Conservation Act, 1999.
