Reintroducing the marsupials to the mainland has been difficult because many lost their instincts to avoid danger, including steering clear of cane toads, the toxic prey that accelerated their demise. Threats Quolls have been classified as highly endangered species where their numbers are drastically declining in their natural habitats. The tiger quoll, also known as the spotted-tail quoll, the spotted quoll, the spotted-tail dasyure, native cat or the tiger cat, is a carnivorous marsupial of the quoll genus Dasyurus native to Australia. Quoll is covered with coarse coat that can be grey, brown or black in color. Tasmania âhas acted as a Noahâs Ark for some of these species, such as the eastern quoll,â he says. Quolls face a range of threats in urban areas, but Mr Jolly said the species was good at exploiting human habitat for food and water. Eastern quolls are marsupials about the size of a small domestic cat, which is why they're also sometimes called the "native cat."

The Northern Quoll is the smallest of the four Australian quoll species. Reintroducing the marsupials to the mainland has been difficult because many lost their instincts to avoid danger, including steering clear of cane toads, the toxic prey that accelerated their demise. Predation by feral cats is a major threat to Northern Quolls. It would be an unlikely story of survival: by 2003 and due to several factors, the species had declined so rapidly that an insurance population was sent to colonise a remote island. The lack of foxes in Tasmania likely has contributed to the survival of the species there; however, unseasonal weather events and predation by feral cats are thought to have contributed to a possible recent decline in the Tasmanian population. Quolls will eat insects or carrion, and will hunt rats, rabbits, birds, and lizardsâeven animals larger than themselves. To give the small population the best shot at survival, he urged residents to keep cats indoors â they prey upon quolls and also compete with them for food.

In March 2018, 20 quolls were transplanted from Tasmania to the mainland of Australia, where they went extinct 50 years ago. Quolls with two parents showing âtoad-smartâ behavior were far less likely to try a non-lethal toad leg than other quolls were. Scientists attribute disease, predators, and habitat loss for their disappearance more than 50 years. Quolls are also more distantly related to the extinct thylacine, or Tasmanian tiger, says Nicholas Dexter, senior project officer at Booderee National Park in New South Wales, where quolls were recently reintroduced.
