What is AWC doing?

AWC has established a new population of Greater Stick-nest rats on mainland Western Australia, within the 7800-hectare feral predator-free fenced area at Mt Gibson Wildlife Sanctuary. More recently, AWC returned the Greater Stick-nest rats to NSW for the first time in over 160 years, translocating 40 Greater Stick-nest Rats to Mallee Cliffs National Park in September 2020. This translocation was in partnership with the NSW National Park and Wildlife Service as part of the New South Wales Government’s Saving Our Species program.

Threats to Wildlife

Like many small to medium-sized Australian mammals, Greater Stick-nest Rats are highly susceptible to predation by foxes and cats – which caused their extinction on mainland Australia. Introduced herbivores likely exacerbated population declines by trampling nests and competing for food.

Description

The Greater Stick-nest Rat is large for a native rodent, ranging from 17-26 cm in body length and weighing up to 450 grams. They have fluffy yellow-brown to grey fur on their back and cream fur below, with a blunt snout, large, dark eyes and large, rounded ears. Their long tail is darker above than below, and they have distinctive white markings on their upper feet. At rest, Greater Stick-nest Rats adopt a hunched posture a bit like a rabbit.

Ecology

Stick-nest Rats build huge, communal nests out of dead sticks. Groups of 10 – 20 individuals cooperate to find and drag branches to a central site – usually around a bush is incorporated into the finished nest. Branches are chewed to length and woven together with additionally-collected green vegetation. These nests can be up to 1 metre high and 1.5 metres wide. Tunnels lead from the outside to the centre of these structures, where rats place grass and other soft green vegetation.

Greater Stick-nest Rats are herbivores, feeding on the leaves and fruits of a wide variety of other species, preferring succulent and semi-succulent plants. Breeding can occur year-round but usually peaks in autumn and winter. Females give birth to 1-3 young. Young are well developed at birth and secure themselves tightly to their mother’s teats. They cling to the mother for about a month, until weaning and independence.

Range and abundance

The Greater Stick-nest Rat once ranged across semi-arid regions of southern Australia, including parts of Western Australia, South Australia and western New South Wales. The species declined rapidly after European settlement, disappearing from the mainland by the 1930’s.

A captive breeding program was established in 1985, and the species was subsequently released on a number of offshore islands in Western Australia and South Australia. As numbers have steadily built up, Greater Stick-nest Rats have been reintroduced to a number of mainland predator-free fenced areas.

Translocations 

In September 2020, Australian Wildlife Conservancy returned 40 Greater Stick-nest Rats to mainland Australia’s largest (9,570 hectares) feral predator-free area at Mallee Cliffs National Park, in partnership with the NSW National Park and Wildlife Service as part of the New South Wales Government’s Saving Our Species program.
