Threatened species

Hastings River Mouse (Pseudomys oralis)



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.

IBRA

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

 
New England Tablelands
NSW North Coast
South Eastern Queensland
Sydney Basin

Proportion of the species' distribution on reserve

42% 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
Conduct targeted restoration and rehabilitation of riparian vegetation to create riparian corridors connecting areas of known habitat for the species, as well as maintaining high quality riparian habitat, particularly in corridors connecting important habitat patches. Site
In locations where it is difficult to conduct a prescribed burn, implement slashing or other mechanical removal of mid-storey vegetation when habitat is becoming unsuitable due to high densities of mesic species (e.g. wattles). Ensure that the response of both the vegetation and the mouse are monitored in the period following. Site
Undertake a trial of supplementing habitat with artificial refugia - coarse woody debris (e.g. log halves and hearts), following fire events in locations where the species is known to occur. Include a monitoring component to measure usage of the artificial habitat and population response. Site
Liaise with land managers undertaking forestry activity in areas where the species is known to occur to encourage the retention of coarse woody debris (e.g. head and butt residue) following harvesting. Area
In locations where implementing prescribed burns is feasible, manage fire using cool burns in a mosaic across the landscape, burning patches at a frequency of 5-10 years as appropriate to the vegetation/site (burn when wattles and other mesic species begin to dominate the mid-storey). Area
Liaise with landholders and land managers on the species' habitat to encourage practices that retain coarse woody debris and minimise disturbance to the ground layer - discourage grazing and high intensity fire. Where possible, negotiate landholder agreements that promote sensitive management of the species' habitat (e.g. in-perpetuity covenants). Area
Conduct targeted survey for the species at sites where there has been little recent survey and where there has been no disturbance from fire, grazing or forestry for more than 30-50 years (e.g. Werrikimbe National Park, Timbarra, Gibraltar Range), to better understand long-term population persistence and response to disturbance, especially fire. Ensure that very high trap hygiene standards are maintained to avoid any bias due to trap avoidance. Incorporate into survey design the ability to evaluate any effects of competitive displacement by bush rats Rattus fuscipes.Site
Develop specific management guidelines for land managers and land ownersSite

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.
