description Eastern bettong Overview
The eastern bettong is a small marsupial in the family Potoroidae, native to eastern Australia. The species became extinct on the Australian mainland, likely due to predation by introduced red foxes and feral cats, but a population persisted in Tasmania. Eastern bettongs are nocturnal and feed mainly on underground fungi, particularly truffles, as well as tubers, roots, and seeds. Reintroduction efforts have included releases of the species into fenced predator-free reserves near Canberra.
help Eastern bettong FAQ
Why did eastern bettongs disappear from mainland Australia?
Predation by introduced foxes and habitat changes contributed to their disappearance from the mainland, leaving Tasmania as their natural stronghold. Their mainland extinction occurred long before the species was returned to protected sites near Canberra.
Where were eastern bettongs reintroduced near Canberra?
Animals were moved from Tasmania into predator-controlled reserves in the Australian Capital Territory, including Mulligans Flat Woodland Sanctuary. The reintroduction program began in 2012 and established a mainland insurance population.
Why are eastern bettongs called ecosystem engineers?
They dig extensively while searching for fungi, roots, and other foods, disturbing and mixing the soil. Those small pits can influence water capture, seed germination, nutrient movement, and the structure of woodland ground cover.
Are eastern bettongs the same as rat-kangaroos?
They are close relatives commonly grouped among the rat-kangaroos, but the eastern bettong belongs to the potoroid family rather than being a true rat. Like other bettongs, it is a small hopping marsupial with strong hind limbs and a long tail.
