Notification: Parks and Wildlife Service is part of the new Department of Biodiversity, Conservation and Attractions (DBCA).

The Western Australian Threatened Species Scientific Committee meets at least annually to consider nominations to list or delist threatened species, or to change the threat ranking of listed species.

The public is invited to submit nominations to amend the current threatened species lists (Rare Flora and Specially Protected Fauna lists). Nominations may be forwarded at any time to This email address is being protected from spambots. You need JavaScript enabled to view it.

The listing process:

  1. The public is invited to submit nominations to add species and subspecies to, or delete species or subspecies from, the current lists, or to change the threat ranking of listed species.
  2. The Threatened Species Scientific Committee meets to review the nominations and makes recommendations to the Minister for Environment, via the Director General of the Department of Parks and Wildlife.
  3. The Minister for Environment endorses or rejects the nominations.
  4. The threatened species lists are updated and published in the Western Australia Government Gazette, usually annually. The lists are then made available on the threatened plants and threatened animals pages.

Threatened Species Scientific Committee meetings are usually held near the end of the first quarter of the calendar year. The closing date for nominations for committee meetings is the last Friday of January that year.

Nominations currently being considered:

The following threatened species nominations have been received for consideration at the next scheduled meeting or are being considered by the Minister for Environment subsequent to that meeting. Note; this list is being continually updated as nominations are submitted.

Nominations submitted to the WA TSSC will be reviewed in accordance with a common assessment method for assessing and listing threatened species which has been established between the Commonwealth and State Governments. The common assessment method is consistent with the best practice standards set by the International Union for Conservation of Nature (IUCN) and will ensure that efforts by all Governments to protect species will be targeted at those species in the greatest need of protection.

Successful WA nominations will be provided to the Commonwealth Department of the Environment for amendments to the National Threatened Species List under the Commonwealth Environment Protection and Biodiversity Conservation (EPBC) Act 1999.

The public is invited to submit information, on any of the species nominated below that might assist in the assessment of the conservation status or management of the species.  When species are nominated they will be shown below without a link to the actual nomination form.  Information unlikely to be known to the Department may be provided at this time by email to This email address is being protected from spambots. You need JavaScript enabled to view it..  Once a nomination has been verified as meeting the requirements of the TSSC and common assessment method, a hyperlink will be inserted linking to the nomination form enabling comments to be provided on the detail provided in the form.  Members of the public may also email This email address is being protected from spambots. You need JavaScript enabled to view it. to request notification when the nomination form is available for comment.

At the conclusion of the assessment process, once the Minister’s decision is available, the tables below will be updated to show the outcome of the assessment process.
