Tiger Quoll
There are four species of quolls. The largest species, also known as tiger quolls, the spotted-tailed quoll is the second largest carnivorous marsupial on the Australia mainland after Tasmanian devils. They live in a variety of habitats, are mainly solitary animals and will make their dens in rock shelters, small caves, hollow logs, and tree hollows and feed on prey such as possums, bandicoots, rabbits, birds, and reptiles.
Quolls have a fascinating breeding cycle – The female calls or “clucks” when she is in oestrus (season) and her neck swells. After a gestation period of 3 weeks, she will give birth to up to thirty young. When spotted-tailed quolls give birth, their offspring are about the size of a grain of rice and up the fur on the mother’s belly and into the pouch where they attach on to a teat. With only 6-7 teats available only that number of young can survive. The mother carries her joeys in her pouch until about 2 ½ months of age at which point, they are left in a nest in the den. The young are then weaned and are independent at 5 months and mature by one year of age. They are short lived with a life expectancy of only up to five years. The joeys grow to about 2 kg for females and 4 kg for males, by the time they reach adulthood.
The spotted-tailed quoll population is seriously threatened throughout mainland Australia. Listed as endangered on the mainland, the introduction of feral animals such as foxes, cats, and dogs, as well as diseases and the logging of their forest habitats, have greatly reduced their numbers. Historic logging of forests and the threat of global warming has for the first time seen many previously very wet forests drying with some even burning.
Several new forest reserves and linkages have been created where the species has been recorded. Feral animals, in particular fox and cat control measures, are being implemented in key habitats. To avoid conflict with people tips on how to “quoll proof” hen houses has been made available. Camera traps and trained scat/scent dogs are being used to detect and monitor populations.
A captive breeding insurance population is managed in Australian wildlife parks and zoos such as ours. Genetics are tightly managed and being relatively short-lived, animals are moved between organisations for breeding on a regular basis.
Our Zoo is one of the top breeding facilities for this species with over forty bred over a twelve-year period.
