Species listing

Find out how threatened species are listed and how you can contribute to the listing process.

The NSW Scientific Committee (the Committee) determines which species, populations and ecological communities are listed as endangered, vulnerable or presumed extinct under the NSW Threatened Species Conservation Act 1995 (TSC Act).

The Committee also identifies key threatening processes.

Listing is used to:

  • add a species, population or ecological community to schedules in the TSC Act
  • reclassify a species or ecological community and move it from one threat category to another
  • delist a species, population or ecological community

Read about threatened species listing categories.

The TSC Act requires that listing decisions are:

  • made by an independent scientific body, i.e. the Committee
  • scientifically robust and based on the best available scientific information
  • completed within a suitable time period that allows for thorough assessment against appropriate criteria
  • made on scientific grounds only.

How is species status decided?

The NSW Scientific Committee uses criteria in the Threatened Species Conservation Regulation 2010 to classify species, populations and ecological communities as critically endangered, endangered or vulnerable.

The criteria are adapted from the Commonwealth Environment Protection and Biodiversity Conservation Regulations 2000 and International Union for the Conservation of Nature (IUCN) criteria.

The Committee considers factors that include:

  • population size
  • reduction in geographical distribution and habitat quality
  • sensitivity to human activities
  • stochastic (randomly determined) events.

For more details, read the Guidelines for interpreting listing criteria.

Who can nominate?

Any person or organisation can nominate a species, population, ecological community or key threatening process for listing, delisting or changing its threat category under the TSC Act.

How do I comment on a proposed listing?

Any person or organisation can make a submission to the NSW Scientific Committee and provide additional information for consideration before final determination.

The Committee publishes notices of preliminary determinations:

The public consultation period is usually 30 days.
