The numbat – a small and little-known Australian marsupial – is one of the world’s most endangered animals. Conservationists are working hard to save them by building vast, predator-free sanctuaries.

It was once widespread across southern Australia, but is now restricted to several small colonies in Western Australia. It is therefore considered an endangered species and protected by conservation programs.
