Pseudomys gouldii

Pseudomys gouldii is a medium-sized native rodent belonging to the family Muridae, characterized by soft grey-brown fur, a pale underside, and a long tail relative to its body length. Like other members of its genus, it is a nocturnal, ground-dwelling species that constructs burrows and shelters in dense vegetation. It feeds on seeds, plant material, and invertebrates, and likely contributes to seed dispersal and soil turnover within its ecosystem, as well as serving as a prey source for native predators.

Historically found across mainland Australia, the species now persists in more limited coastal and island habitats, including subtropical and tropical mangrove vegetation, shrubland, and marine coastal and supratidal zones. Its current range is restricted to Australia.

The species faces ongoing pressure from invasive non-native predators and competitors, which prey on individuals and disrupt native ecological balance. Habitat shifting and alteration, driven by land-use change and environmental disturbance, continue to reduce the extent and quality of suitable habitat. Altered fire regimes, including both increased fire frequency and fire suppression practices that change vegetation structure, further degrade shelter and food resources.

Conservation efforts include control programs targeting invasive predators, habitat protection and restoration in coastal and island refuges, and monitoring of population trends to guide management. Predator-free island populations have played a role in supporting recovery efforts for related species in this genus.

Currently listed as Vulnerable, the species shows an increasing population trend, suggesting that existing conservation interventions are having a positive effect. However, its restricted range and dependence on continued predator control and habitat management mean its long-term security remains contingent on sustained conservation investment.
