The Australian government's Threatened Species Action Plan 2022-2032 selected over 100 priority species derive from consultation with threatened species experts and the wider community. While all species are important, focusing on a limited number of species can help target effort and resources so that outcomes can be achieved, measured and shared.
Description
The Shark Bay Mouse is a long-haired mouse, also known as the Djoongari. The Djoongari became extinct on the mainland by the late 19th century and the only natural surviving population is on Bernier Island where they inhabit coastal dune vegetation. Little is known about their diet, but like many rodent species they appear to be vegetarian/omnivores.
Threats
The main current potential threats to the Djoongari are fire and the possibility of black rats being introduced to the island in the absence of appropriate biosecurity protocols. The past threat that would have aided in their reduced numbers is suspected to be predation by foxes and feral cats.
