Two dozen of the cat-sized carnivorous marsupials known as Tasmanian Devils have been released into the wild on Australia's mainland, 3,000 years after they became locally extinct. Conservationists have described the initiative as a "historic" step.
Aussie Ark, along with a coalition of other conservation groups, revealed on Monday that they had released 26 of the feisty mammals into a 400-hectare (1,000-acre) sanctuary at Barrington Tops, about three-and-a-half hours north of Sydney.
Tim Faulkner, president of Aussie Ark, said the "historic" releases, which took place in July and September, were the first steps in a project akin to the successful move to return wolves to Yellowstone National Park in the United States in the 1990s.
Sixteen years of preparation
After 16 years of work, including the establishment of mainland Australia's largest Tasmanian Devil breeding programme, Faulkner said it was "incredible and surreal" to have reached the goal.
Tasmanian Devils, which weigh up to 8 kilograms (18 pounds) and have a black or brown coat, typically prey on other native animals or scavenge carcasses.
According to government environmental authorities, devils are not dangerous to humans or livestock but will defend themselves if attacked and can cause serious injury.
Population ravaged by facial tumours
The animals -- known for their extremely loud growl, powerful jaws and ferocity when confronting rivals over food or mates -- are classified as endangered after a contagious facial tumour disease ravaged the remaining population on the Australian island state of Tasmania.
It is estimated that fewer than 25,000 Tasmanian Devils still live in the wild, down from as many as 150,000 before the mysterious, fatal disease first struck in the mid-1990s.
On Australia's mainland, they are believed to have been wiped out by packs of dingoes -- wild dogs native to the vast continent -- an estimated 3,000 years ago.
"Devils present one of the only natural solutions to the control of fox and the cat, and the fox and cat are responsible for nearly all of our 40 mammal extinctions (in Australia)," Faulkner added.
"So there's more than the devil at stake here."
