Threatened species

Yellow-bellied Glider (Petaurus australis)

Species Action Statement

This species has been assigned to the Landscape species management stream under the Saving our Species (SoS) program.

Justification for allocation to this management stream

This species is distributed across relatively large areas and is subject to threatening processes that generally act at the landscape scale (e.g. habitat loss or degradation) rather than at distinct, defineable locations.

Conservation status

Management objectives

This action statement aims to ensure that the species is secure in the wild in NSW and that its NSW geographic range is extended or maintained.

Species sightings and management sites across NSW

The map below displays the species’ distribution in NSW, based upon the species’ geographic range, habitat distribution or area of occupancy (to as high a resolution as available data allow, using a range of data sources).

Information about the species’ habitat and ecology is available here.

The map may also display one or more management sites where management of important populations is underway. More information is available in the tables below.


The species occurs in the following IBRA (Interim Biogeographic Regionalisation for Australia) regions in NSW:

Australian Alps
New England Tablelands
NSW North Coast
NSW South Western Slopes
South East Corner
South Eastern Highlands
South Eastern Queensland
Sydney Basin

Proportion of the species' distribution on reserve

34% of the species' distribution occurs on reserve (within NSW National Parks and Wildlife Service estate).

Critical actions for this species

The key threats to the viability of landscape-managed species are loss, fragmentation and degradation of habitat, and widespread pervasive factors such as impacts of climate change and disease. Many of these threats are addressed by NSW planning, native vegetation, and biodiversity legislation, policy and programs including the offsets program (BioBanking, NSW Biodiversity Offsets Policy for Major Projects), Biodiversity Certification, management of environmental water and reservation under the National Parks and Wildlife Act 1974.

Threats to this species are outlined here.

The actions listed in the action toolbox are supplementary to NSW legislation, policy and programs and can be used by stakeholders, where applicable to guide management at a site, regional or state scale.

Action toolbox

Action DescriptionScale
Protect and maintain areas of high quality habitat, particularly mature forest occurring in high rainfall areas on nutrient rich soils, with tall trees bearing large hollows, sap-feeding trees and a diversity of winter flowering eucalypts for pollen and nectar. Sap-trees may be from a variety of species but are typically smooth-barked eucalypts. Protect areas of younger forest that will develop into suitable habitat for yellow-bellied gliders. Where possible negotiate conservation agreements with landholders, agreements should preferably be funded and in perpetuity. Site, Area
Undertake revegetation, using a mix of locally appropriate native species that will develop into high quality habitat. Revegetation should focus on expanding existing smaller (less than 30ha) areas of suitable habitat. Site
Improve and maintain connectivity between patches of suitable habitat. Improve width and condition of existing habitat links either by natural regeneration or augmentation plantings of suitable native species. Establish corridors between isolated patches of known habitat. Corridors should be at least 50m wide, and any plantings should including potential food trees and hollow-developing species. Site, Area
Limit width of linear clearings through suitable habitat to ensure gliders can cross (distance depends on height of neighbouring vegetation and topography, but generally should be less than 100m). If necessary provide glider bridges or poles to allow gliders to cross. State
Retain and protect trees with feeding incisions, and species which are known food trees (including winter flowering eucalypts that provide pollen and nectar). Augment degraded habitat by planting food tree species. State
Retain and protect hollow-bearing trees in suitable habitat. Ensure hollow availability into the long term by protecting recruit trees, that is trees that will be able to provide hollows when current hollow-bearing trees have died and fallen. State

How will this species be managed?

Key management sites for this threatened species are being identified by the NSW Government and other program partners, where feasible, cost-effective and beneficial management actions can be undertaken. Currently, no management sites have been identified for this threatened species.
