Watch at FMovies. Warru, or black-footed rock-wallaby, is one of South Australia's most endangered mammals. In 2007, when numbers dropped below 200 in the APY Lands in the remote north-west of the State, the Warru Recovery Team was formed to help save the precious species from extinction. Bringing together contemporary science, practical on-ground threat management and traditional Anangu ecological knowledge, this unique decade-long program has celebrated the release of dozens of warru to the wild for the first time.
