Bettongia pencillata
Also known as a woylie, this is an extremely rare, small marsupial that is endemic to Australia. There were two subspecies, but one is now extinct. Since 2001, the population has crashed by over 90% which means the entire species is at risk of becoming extinct in the wild.
Habitat & threats
Preferring open woodlands and grasslands, with a dense understory where they can create pathways in tussocks of grasses. The exact cause of this rapid population crash remains uncertain. Predation from feral cats and foxes as well as habitat destruction contribute to the recent decline of the species.
Diet
The brush-tailed bettong has an unusual diet for a mammal. Although it may eat bulbs, tubers, seeds, insects, and resin of the hakea plant, the bulk of its nutrients are derived from underground fungi which it digs out with its strong foreclaws.
Breeding and social dynamics
The female can breed at six months of age and give birth every 3.5 months. Its lifespan in the wild is about four to six years. The brush-tailed bettong is able to use its tail, to carry bundles of nesting material. It builds its dome-shaped nest in a shallow scrape under a bush.
Conservation
As of 2011, the global population is estimated to be less than 5,600 individuals. It is said to be "on the brink of extinction”. There are a number of protected areas free of predators where conservation work is being focused as well as a captive breeding programme in Australia and European zoos, including Shaldon.
