The Large-eared Hopping-mouse was last collected in July 1843 near the Moore River, Western Australia, close to where New Norcia is now situated (Mahoney 1975, Flannery and Schouten 2001, Dixon 2008), and has not been seen since (Burbidge 2004). Absence of the species from extensive subfossil collections (Burbidge et al. 2009) suggests that it was restricted to the western margin of the wheatbelt of Western Australia. It may have survived well beyond the date of last collection, noting the lack of scientific collecting in the range area in the 19th and early 20th Centuries.

Habitat and Ecology [top]

Habitat and Ecology:The habitat requirements of this species are unknown. The land surrounding the Moore River originally consisted of coastal heathland, woodland, and open forest (Dixon 2008).

Threats [top]

Major Threat(s): Extinction is considered to be primarily caused by predation by feral cats. The Large-eared Hopping-mouse’s habitat, loamy valley soils with grass, was used for sheep herding at the time of extinction; this would have degraded its habitat and collapsed its burrows. Evidence for epizootic disease as the primary factor, but probably interacting with drought and predation by feral cats as secondary factors, in decline and extinction of many mammal species in Western Australia; many of these declined before the arrival of foxes (Abbott 2006).
