Threatened species

Spotted-tailed Quoll (Dasyurus maculatus)

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:

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

Proportion of the species' distribution on reserve

68% 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
Conserve old-growth forest stands and other areas of known habitat under perpetual, funded conservation agreements such as BioBanking agreements, conservation property vegetation plans or inclusion in the conservation reserve system.Site
Identify and target restoration and revegetation projects at areas where connectivity between large areas of known habitat is compromised, with the aim of increasing the width, condition and security of critical landscape links.Area
Implement (or augment) coordinated, cross-tenure, landscape scale predator control programs in areas where significant populations of spotted-tailed quoll are known to occur, and monitor populations of the target introduced predator. Area
Monitor significant spotted-tailed quoll populations to investigate the impact of fox and wild dog baiting.Site
Design and distribute an educational brochure for designing 'quoll-proof' poultry runs and aviaries and distribute. State
Modify poultry runs and aviaries based on best-practice guidelines. Site
Incorporate methods to reduce the numbers of spotted-tailed quolls killed at sections of roads where road kills are frequently reported. Assess the effectiveness of different mitigation methods. Site
Monitor survival of spotted-tailed quoll populations in habitat newly colonised by cane toads.Area

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