Species listing categories

Threatened species are listed in categories according to the level of threat they face.

These categories include:

  • presumed extinct
  • critically endangered (schedule 1A)
  • endangered (schedule 1)
  • vulnerable (schedule 2).

The TSC Act also lists key threatening processes under schedule 3.

Criteria in the Threatened Species Conservation Regulation 2010 (the regulation) are used to determine which species, populations and ecological communities fit into these categories.

Presumed extinct

Species are presumed extinct if they have not been recorded in their known or expected habitat in NSW over a time frame appropriate to their life cycle and type.

Critically endangered

Species and ecological communities are listed as critically endangered if they are facing an extremely high risk of extinction in NSW in the immediate future.

Endangered

Species or ecological communities are listed as endangered if they:

  • face a very high risk of extinction in NSW 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
  • are scattered, fragmented or near the limit of their geographical range
  • are, or are likely to be, genetically, morphologically or ecologically distinct
  • are otherwise of significant conservation value.

Vulnerable

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.

Key threatening process

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.
