The $1m plan to save some of Australia's most vulnerable species

Aussie Ark will receive $1 million to expand its work protecting threatened wildlife at a scale "never seen before".

The Barrington Tops-based conservation organisation has been named the recipient of the Ian Potter Foundation environmental grant, which will be paid over three years, starting immediately.

Aussie Ark said on Tuesday the funds would go towards specialist breeding programs, habitat protection, and re-wilding initiatives of selected species.

These include the broad-toothed rat, New Holland mouse, broad-headed snake, three threatened frog species and three endangered freshwater turtle species.

Director and co-CEO of Aussie Ark, Liz Gabriel, said this grant would enable Aussie Ark to rewild endangered species at a scale "never seen before".

"This investment by the Ian Potter Foundation is a transformational commitment to threatened species conservation in NSW," Ms Gabriel said.

"Together with [Aussie Ark], our partners in universities, the conservation sector and community, we can deliver conservation outcomes at a scale that simply would not be possible otherwise."

Aussie Ark said the grant would help expand its specialist conservation facilities and programs.

This included conservation breeding facilities, trap-and-release programs, habitat restoration and site preparation, health screening, including disease mitigation and genetic testing, and ongoing scientific monitoring.

Hayley Shute, co-CEO of Aussie Ark said the Ian Potter Foundation was supporting a future where endangered species would not simply survive but would be "actively restored" into functioning ecosystems.

"Through this project we will continue to combine cutting-edge science with practical on-ground conservation to ensure these species have a future in the wild," she said.

The Ian Potter Foundation environment program manager, Sam Armstrong, said they were proud to support Aussie Ark.

"This project reflects the kind of long-term, practical conservation work needed to restore ecosystems and give vulnerable native wildlife a stronger future," Ms Armstrong said.
