Preliminary determinations by date

This page shows all current preliminary determinations. Some are on public exhibition, and you can send a submission to the NSW Threatened Species Scientific Committee about them.

Your submission must be signed, and it must include a return address. You should send it by post (emails will not be accepted) to the following address:

NSW Threatened Species Scientific Committee
PO Box 1967
Hurstville NSW 2220.

As you'll see from the closing date below each listing, some of the determinations are no longer on public exhibition. Please do not send submissions about these determinations.

How nominations are assessed

The Scientific Committee assesses whether species or ecological communities that occur in NSW should be listed as threatened species or ecological communities  (ie Critically Endangered, Endangered or Vulnerable species) in the Schedules of the Act. The NSW TSSC also identifies species that are extinct or extinct in the wild in NSW, collapsed ecological communities and key threatening processes.

Under the Act, the NSW TSSC must initially assess a species’ risk of extinction in Australia. If a species is assessed at being threatened Nationally then the NSW TSSC will list that species in NSW at that level. If a species is not threatened at the national scale then the NSW TSSC can assess the extinction risk of the species in NSW. The Act and the Biodiversity Conservation Regulation 2017 sets out the criteria used to make these assessments. These criteria are based on the assessment criteria developed by the International Union for Conservation of Nature (IUCN). The Committee’s guidelines provide information on how the listing criteria are interpreted in assessments.

Common assessment method

The NSW Government has signed a Memorandum of Understanding (MOU) with the Commonwealth Government and other State and Territory jurisdictions to implement a Common assessment method (CAM) of species using IUCN criteria.

The CAM will ensure there is a consistent approach based on IUCN criteria to assess threatened species in Australia. Through information sharing and mutual recognition of assessments, national assessments undertaken by one jurisdiction may be accepted by other jurisdictions. This will ensure a species is listed at the same level of extinction risk at both the Commonwealth and State level and reduce the duplication of assessments.

Bioregions referenced in Committee determinations

In determining the bioregions where an ecological community occurs, the NSW Threatened Species Scientific Committee uses the Biogeographic regionalisation of Australia.  The Committee’s Determinations indicate which version has been referenced for a particular ecological community. As a guide, the Committee has used the following versions:

Version 4 - Determinations made before March 2013:

The Committee used Thackway R, Cresswell ID (1995) An interim biogeographic regionalisation for Australia: a framework for setting priorities in the National Reserve System Cooperative Program. (Version 4.0. ANCA: Canberra).

View a map of the bioregions (PDF 691KB) from Thackway and Cresswell 1995.

Version 7 - Determinations made since March 2013:

The Committee currently uses SEWPaC (2012) Interim Biogeographic Regionalisation for Australia, Version 7. Department of Sustainability, Environment, Water, Population and Communities.

Preliminary determinations sorted by date

Determinations made before 25 August, 2017 refer to the Threatened Species Conservation Act, 1995 and the Threatened Species Conservation Regulation, 2010. This legislation and regulation has been replaced by the Biodiversity Conservation Act, 2016 and the Biodiversity Conservation Regulation, 2017.
