Therufous hare-wallaby (Lagorchestes hirsutus), also known as themala[4], is a smallmacropod found inAustralia. It was formerly widely distributed across the western half of the continent, but naturally occurring populations are now confined toBernier Island andDorre Island Islands offWestern Australia.[5]
Although once widespread in the central and western deserts, predation by feral cats and foxes, and destructive wildfires, caused the last wild population on mainland Australia to go extinct in the early 1990s.[6] Despite its extinction in the wild, the mainland subspecies persisted in captivity.[7]
The species, which is currently classified as vulnerable,[2] hasrufous-grey fur and is the smallest hare-wallaby, weighing just 800-1,600 grams.[6] It is a solitarynocturnal herbivore that feeds on herbs, leaves and seeds.
Mala prefer spinifex sandplain habitat; the animals build burrows under largespinifex hummocks. The burrows are tunnel-like structures with a spinifex roof. This provides a cool refuge during the heat of the day. In summer, they are likely to dig deeper burrows to withstand searing desert temperatures.[6]
Captive stocks of the mainland subspecies are currently being reintroduced in theTanami Desert in theNorthern Territory.[5] In July 2019, the first reintroductions into theNewhaven Sanctuary were conducted, with the release of 30 individuals into the 9,400 hectare, feral predator-free area.[6]
Animals from both Bernier Island and Dorre Island have recently been translocated toDirk Hartog Island following the complete removal of livestock and feral cats from the landscape.[8]
The first European to describe the rufous hare-wallaby wasJohn Gould (1844) inThe Mammals of Australia.
Four distinct subpopulations of this species have been described as subspecies, especially with regard to their conservation status. Estimates of these island colonies numbers were between 4,300 and 6,700 in 1994; the environmental conditions cause fluctuations in the total number of animals.
Two possible subspecies are found in range restricted to islands near Western Australia.
The fourth is an unnamed subspecies that has been conserved by relocation.
A species ofLagorchestes, the smallest of the genus, the combined length of the head and body is 310 to 390 millimetres, greater than the tail length of 245 to 300 mm. Their weight range is 800 to 1,600 grams and body form is comparatively light and delicate. The colouration of the pelage is rufous overall, greyer at the upper back and yellowish at the underside and forearm. Some parts of the population, such as those at the Bernier and Dorre island in Shark Bay, have greyer fur at the underside. The sandy colour of the tail terminates in a grey tip. The fur is long and shaggy in appearance.[10]
For theAnangu, orAboriginal people, the Mala or "hare wallaby people" are important ancestral beings. For tens of thousands of years, the Mala have watched over them from rocks and caves and walls, guiding them on their relationships with people, plants and animals, rules for living andcaring for country. MalaTjukurpa, the Mala Law, is central to their living culture and celebrated in story, song, dance and ceremony.[11]
