SPOTTED- TAILED QUOLL

The spotted-tailed quoll (dasyurus maculatus), also known as the tiger quoll, is the largest carnivorous marsupial on mainland Australia. It plays a vital role in maintaining ecosystem balance as a predator. Its presence benefits numerous other species, making it a high-priority species for conservation. Spotted-tailed quolls are present at Odonata’s Mt Rothwell sanctuary.


Physical description

The spotted-tailed quoll is a distinctive species with a reddish-brown coat covered in white spots, a long, spotted tail, and sharp claws for climbing and hunting. It is the largest of the quoll species, with males weighing between 2.8 to 4.6 kg (occasionally up to 7 kg) and females between 1.5 to 2 kg. It has strong jaw muscles and excellent climbing abilities.

Habitat and distribution

Spotted-tailed quolls are found primarily in Tasmania, Victoria, New South Wales, and Queensland. They inhabit rainforests, wet sclerophyll forests, and coastal woodlands with dense tree cover and ample prey.

Behaviour and diet

Spotted-tailed quolls are solitary and nocturnal, except during the breeding season. They are opportunistic carnivores, feeding on small mammals, birds, reptiles, and carrion.

Breeding

Breeding occurs during winter. After a gestation of around 21 days, females give birth to up to six young that develop in the pouch and then a den. Only the female provides parental care.

Success in the field

A few spotted-tailed quolls are present at Odonata’s Mt Rothwell Sanctuary. Odonata is exploring further conservation strategies, including a potential research project to evaluate the role of quolls in rodent control. A study is also underway in East Gippsland to investigate population declines and plan future conservation strategies for the region..
