Threatened species

Squirrel Glider (Petaurus norfolcensis)

Saving our Species strategy

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 SoS strategy aims to ensure that the species is secure in the wild in NSW and that its NSW geographic range is extended or maintained and maintain its conservation status under the BC Act.

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:

NSW South Western Slopes
South Eastern Highlands
Sydney Basin

Proportion of the species' distribution on reserve

2% 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
Raise public awareness of the importance of large old trees (living and dead), which provide important hollow and food resources. Protect large old trees and ensure their continued presence in the landscape by retaining medium sized trees, facilitating regeneration, and undertaking replanting. Large old trees within, adjacent to, or connecting vegetation remnants are particularly important. Site
Identify important populations and engage stakeholders in the development and implementation of a local area management plan (a map based document detailing the works necessary to secure the long term viability of the population). Undertake baseline studies to support the preparation of local area management plans (LAMPs). Area, State
Reduce direct mortality due to entanglement on barbed wire, vehicle collisions, and predation by cats and dogs. Encourage the use of plain wire fencing and the covering of barbed wire with polypipe. At sites with a high risk of vehicle collision, install crossing structures (e.g. rope bridges, glide poles) and/or reduce the canopy gap through revegetation. Confine cats and dogs at night. Site
Protect, manage and restore habitat, prioritising sites within a region that may better function as drought refuges. Encourage the retention of a floristically and structurally diverse understorey, and raise public awareness of the damage caused to food resources by slashing/underscrubbing and over-grazing. Site, Area
Ensure populations remain connected by avoiding gaps greater than 50m between habitat patches and along linear remnants. Eliminate gaps through revegetation or the installation of crossing structures (e.g. rope bridges, glide poles), focusing on important movement pathways. Investigate the influence of habitat fragmentation on gene flow in different landscapes across the species' distribution. Site, Area, State
Identify sites where hollows are limiting and develop and implement strategies to increase hollow availability that have clear objectives and include monitoring, maintenance, and reporting requirements. Actions include nest box installation, the humane control of introduced species, and the protection of trees having the potential to develop hollows. Site

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, 2 management sites have been identified for this threatened species.
