Threatened Species and Ecological Communities

On this page

A species or ecological community is threatened if it is likely to become extinct in the foreseeable future.

A process is threatening if it has the potential to threaten the survival of a species or ecological community in the ACT region.

The Nature Conservation Act 2014 (ACT) establishes a formal process for the identification and protection of threatened species and ecological communities. It requires the Scientific Committee to advise the Minister for the Environment and Heritage (the Minister) of native species and ecological communities that are threatened in the ACT, and ecologically significant threatening processes. Following an assessment against criteria, the Committee will recommend that they be listed accordingly.

Common Assessment Method

A common assessment method (CAM) has been established by the Australian Government, States and Territories for the assessment and listing of all nationally threatened species (under the Environment Protection and Biodiversity Conservation Act 1999 (Cth). State and Territory threatened species lists will only contain species that occur in their jurisdiction, however the category of a species will be the same where it is listed in more than one jurisdictions.

This does mean that the category of some ACT threatened species will change so that it is aligned with the rest Australia. A species is listed in one of the regional categories if it does not meet the criteria for national listing.

Further information about the CAM is available on the Department of the Environment and Energy website.

Threatened native species

The formal list of threatened species in the ACT is published in NI2020-300 on the ACT legislation register. A species may be assessed at the national scale and listed in a national category as:

  • extinct
  • extinct in the wild
  • critically endangered
  • endangered
  • vulnerable
  • conservation dependent

A native species occurring in the ACT may be listed in a regional category if it does not meet national criteria:

  • regionally threatened
  • regionally conservation dependent
  • provisional

The list below provides the scientific and common names of threatened species in the ACT according to their listing category. A link is provided with their respective action plan or conservation advice.

Threatened Ecological Communities

The formal list of threatened ecological communities in the ACT is published in NI2020-301 on the ACT legislation register. There are currently three listed ecological communities in the ACT: Natural Temperate Grassland, Yellow-box/Red-gum Grassy Woodland, and High Country Bogs and Associated Fens.

An ecological community may be listed as:

  • collapsed
  • critically endangered
  • endangered
  • vulnerable
  • provisional

Threatened ecological communities of the ACT


High Country Bogs and Associated Fens

The ACT High Country Bogs and Associated Fens (bogs and fens) community is consistent with the Alpine Sphagnum Bogs and Associated Fens ecological community listed nationally under the Environment Protection and Biodiversity Conservation Act 1999 but includes some bogs and fens at lower elevation. The bogs and fens community is defined by the presence or absence of Sphagnum spp. on a peat substratum. Sphagnum is not always a major floristic component, and there are some sites in the community where Sphagnum has become depleted or been lost as a result of disturbance. In these cases, the site is considered part of the community if other key species are present and a peat substratum is evident (see the Conservation Advice).

Critically endangered

Natural Temperate Grassland

A naturally occurring grassland of the temperate zone, dominated by native perennial tussock grasses, with associated native herbs and native fauna.

Yellow Box/Red Gum Grassy Woodland

A naturally occurring woodland of the temperate zone, in which Yellow Box co-occurs with Blakely's Red Gum. It includes the species rich understorey of native tussock grasses, herbs and scattered shrubs, together with a large number of native animal species.

Key Threatening Processes

A threatening process may be listed as a key threatening process. Listing is formal recognition of a conservation threat.

Loss of mature native trees

In 2018 the 'Loss of Mature Native Trees (including hollow-bearing trees) and a Lack of Recruitment' was listed as a key threatening process (NI2018-538 - Nature Conservation Key Threatening Processes List 2018 (No 1)). The significant loss of mature trees was determined by the ACT Scientific Committee to be adversely affecting the Superb Parrot (Polytelis swainsonii), Brown Treecreeper (Climacteris picumnus), Glossy Black-cockatoo (Calyptorhynchus lathami) and Little Eagle (Hieraaetus morphnoides); these species are all listed as Vulnerable in the ACT.

An Action Plan (threat abatement plan) is currently under development.

Unnatural Fragmentation of Habitats

In 2019 the ‘Unnatural Fragmentation of Habitats' was listed as a key threatening process (NI2019-822 - Nature Conservation Key Threatening Processes List 2019). The significant unnatural fragmentation of habitat was determined by the ACT Scientific Committee to be adversely affecting the Canberra Grassland Earless Dragon (Tympanocrytis lineata – currently listed as Tympanocrytis pinguicolla and under reassessment for probable uplisting)) and the Macquarie Perch (Macquaria australasica). These species are both currently listed as Endangered in the ACT.


Any person or organisation may make a nomination to the ACT Scientific Committee requesting that the Committee assess a species, ecological community or threatening process for listing. The criteria for listing threatened species and ecological communities are based on the equivalent IUCN criteria and are published in these instruments:

  • DI2016-254 - Threatened Native Species Eligibility Criteria
  • DI2016-255 - Threatened Ecological Communities Eligibility Criteria
  • DI2016-256 - Key Threatening Processes Eligibility Criteria

Conservation Advice and Action Plans

A Conservation Advice is a document prepared accompany the listing of a new species. A draft of each action plan must be released for public comment. Conservation advices are legal instruments and can be found on the ACT legislation register.

Following the listing of a species, ecological community or key threatening process, the Minister decides if an Action Plan is required to be prepared and implemented by the Conservator of Flora and Fauna (Conservator) for a listed threatened species, ecological community, or key threatening process. The Conservator is required to provide a report on the monitoring of the effectiveness of action plans at least every five years. The Scientific Committee must review an action plan every ten years after the plan commences.
