The categories include:
- critically endangered
Species may also be listed as extinct or extinct in the wild and ecological communities listed as collapsed. The Act also lists key threatening processes.
Criteria in the Act are used to determine which species and ecological communities fit into which category.
Species and ecological communities are listed as critically endangered if they are facing an extremely high risk of extinction in Australia in the immediate future.
Species or ecological communities are listed as endangered if they:
- face a very high risk of extinction in Australia in the near future, as determined by the criteria prescribed in the regulation
- are not eligible to be listed as a critically endangered species or ecological community.
Species and ecological communities are listed as vulnerable if they:
- face a high risk of extinction in NSW in the medium-term future, as determined by the criteria prescribed in the regulation
- are not eligible to be listed as an endangered or critically endangered species or ecological community.
Species are listed as extinct if there is no reasonable doubt that the last member of the species in Australia has died
Species that are listed as extinct in the wild are species known to survive in Australia in cultivation, in captivity or naturalised population outside the past range or it hasn't been recorded in its habitat in Australia despite surveys in a time frame appropriate to their life cycle and type.
Ecological communities where the natural occurrence of the ecological community has lost its composition, structure and function.
Key threatening processes
A process is listed as a key threatening process if:
- it adversely affects threatened species, populations or ecological communities
- it could cause species, populations or ecological communities that are not threatened to become threatened.
