to the available teats will be the only survivors. The young remain attached to the teat for 60 to 65 days, begin to develop fur at around 51 days, open their eyes at about 79 days, and are fully weaned at 150 to 165 days. They reach sexual maturity in their first year and typically live for 2–3 years, but can live for up to 7 years in captivity. Conservation Tasmania The eastern quoll likely became extinct on mainland Australia due to predation by introduced predators (red fox) but disease has also been implicated as a potential causative factor of decline. 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 and continuing population declines in Tasmania. The species is currently classified as Endangered by the IUCN. Mainland Australia The last eastern quoll specimen on the mainland was collected as roadkill in Nielsen Park, Vaucluse in Sydney on 31 January 1963, however a taxidermied specimen provided to NSW National Parks and Wildlife Service in 2016 was reported to have been collected in 1989 or 1990 in the Gloucester region of NSW, indicating the species may have survived longer than the generally accepted 1960's decade of its mainland extinction. The NSW National Parks and Wildlife service reported numerous unconfirmed sightings and the species was reported photographed as recently as 2013 in the Nungatta district of NSW. Specimens collected in 2005 and 2008 west of Melbourne, Victoria, are likely connected with a nearby wildlife sanctuary, either as direct escapees, or the descendants of escapees from that facility. Reintroductions Victoria In 2003, the eastern quoll was reintroduced to a 473ha fox-proof fenced sanctuary at Mt Rothwell Biodiversity Interpretation Centre at Mount Rothwell in Victoria. Australian Capital Territory In March 2016, a trial reintroduction of 16 eastern quolls from Mount Rothwell (Victoria), and Tasmania was conducted at Mulligans Flat Woodland Sanctuary in the Australian Capital Territory. Mulligans Flat is a public 485 ha reserve which is surrounded by a predator-proof conservation fence, but is otherwise like other unfenced woodlands in the region. Founders from the first trial had a survival rate of 28.6%, with the majority of mortalities being associated with males dispersing beyond the predator-proof fence. Adopting an adaptive management approach, the second and third trials involved only releasing
