Listed as Extinct because Western desert Aborigines reported that the Yallara died out in the 1960s (Burbidge et al. 1988). The last specimen was from near Koonchera Dune (Cooncherie) in north-eastern South Australia in 1931 (Johnson 2008). A skull of unknown age was found in 1967 in a nest of a Wedge-tailed Eagle Aquila audax south-east of Alice Springs near the edge of the Simpson Desert (Johnson 2008).

Population [top]

Population:This species is extinct. Population size is unknown, but it was probably fairly abundant, especially during good seasons.

Aboriginal people have stated that it survived in the western deserts until c. 1960 (Burbidge et al. 1988) and the skull found in 1967 in a nest of a Wedge-tailed Eagle Aquila audax south-east of Alice Springs near the edge of the Simpson Desert found in 1967 was estimated to be <15 years old.
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:Yallara occurred in sandplain or sand dune deserts, but also occupied mulga Acacia aneura and tussock grass country. They sheltered in a burrow but, unlike the Bilby, they closed the entrance while in residence. They were strictly nocturnal. Limited data on food suggests they were, unlike other bandicoots, mainly carnivorous, eating small mammals, but also seeds and fruit, including of Solanum spp. (Johnson 1989; Flannery and Schouten 2001). The presence of sand in stomach contents suggests that, like the Bilby, they dug to obtain food. Females had eight teats in two rows of four (Johnson 1989).

Threats [top]

Major Threat(s): Predation from introduced feral cats and red foxes is considered to be the major cause of extinction, probably exacerbated by changes in fire regime.

Conservation Actions [top]

Conservation Actions: Yallara are extinct.
