The Kimberley (especially the north Kimberley) region is highly biodiverse and supports an important endemic fauna. The Kimberley region has lower levels of threatened land fauna and extinctions (rodents and marsupials) than other parts of Western Australia.

Kimberley fauna is similar to other northern Australian regions and islands to the north. It includes a number of species not represented further south in Western Australia including two species of crocodile and large spectacular birds such as the Black Necked Stork and Saurus Crane.

The Department of Environment and Conservation (DEC) produce a series of excellent pocket guides (bush books) to the plants, birds and animals in the region.
