Shark Bay Bandicoot

Perameles bougainville is a small, nocturnal marsupial characterised by a pointed muzzle, large ears, and soft grey-brown fur with pale underparts. Weighing under 300 grams, it forages alone at night for insects, larvae, and underground fungi, using its strong forelimbs to dig conical pits in the soil. This digging activity aerates soil and disperses fungal spores, giving the species a modest but meaningful role in ecosystem nutrient cycling within the arid and semi-arid habitats it occupies.

Historically widespread across mainland Australia, the species now persists mainly through translocated and reintroduced populations on predator-free islands and fenced mainland reserves in Western Australia and South Australia. It favours shrubland habitats with dense low vegetation offering cover from predators, though its listed range also touches marine neritic zones associated with offshore island habitats.

Its decline and continued vulnerability stem from predation by introduced red foxes and feral cats, competition and habitat degradation linked to livestock grazing, and altered fire regimes that reduce the shrub cover it depends on for shelter. Interactions with native predators and disease also pose ongoing pressure on small, isolated populations.

Conservation efforts include establishment of fenced, predator-free sanctuaries, active reintroduction programs to islands such as Bernier and Dorre, and ongoing feral predator control on the mainland. Monitoring programs track population trends across these managed sites.

Current data indicate a population trend that is increasing, largely attributable to successful translocations and predator-exclusion measures rather than natural range recovery. The species remains classified as Vulnerable, reflecting its restricted distribution and continued dependence on intensive habitat and predator management for long-term persistence.
