The founder of a Tasmanian Devil breeding facility in the Barrington Tops says the scheme has paid off with at least eight litters born since January.

Devil Ark hosts its official opening today, eight months after 51 Devils were released into a bush setting without the boundaries imposed in other animal parks.

The facility was established in response to the Devil Face Tumour Disease that was causing populations to rapidly decline.

John Weigel says the open enclosure is sustainable long-term because it is cost effective and emulates the Tasmanian Devil's natural habitat.

"We, equally, were guided by the need to do much more to preserve the natural behaviours of the Tassie Devil," he said.

"And so, that's why we picked the ideal property - which is right up the top of the Barrington Tops.

"It looks like Tasmania, is cold like Tasmania.

"There's been four snow falls this year."

Mr Weigel says the breeding facility will ultimately save several native species in Tasmania.

He says if the species were to become extinct it would dramatically affect the natural eco-system.

"Unfortunately what we're seeing with the departure of the Tassie Devil is cats and dogs and, probably, foes are moving in," he said.

"Those species which were quite happy to fit into an eco-system with the devil at the top of the food chain, they're not going to fare well.

"So there's a lot of reasons why we need to make sure the Tassie Devil is not lost."
