Species listing categories

Under the Biodiversity Conservation Act 2016, the NSW Threatened Species Scientific Committee categorises and lists threatened species according to the level of threats they face and the risk of extinction.

 

The categories include: 

  • critically endangered 
  • endangered 
  • vulnerable. 

Species may also be listed as extinct or extinct in the wild and ecological communities listed as collapsed. The Biodiversity Conservation Act also lists key threatening processes. 

Criteria in the regulation are used to determine which species and ecological communities fit into which category. 

Critically endangered 

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. 

Endangered 

Species or ecological communities are listed as endangered if they face a very high risk of extinction in Australia in the near future. 

Vulnerable 

Species and ecological communities are listed as vulnerable if they face a high risk of extinction in New South Wales in the medium-term future. 

Extinct species 

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 or captivity. There may be a naturalised population outside the past range or it has not been recorded in its habitat in Australia, despite surveys in a timeframe appropriate to their life cycle and type. 

Collapsed communities 

Collapse occurs when 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.
