Paruna Wildlife Sanctuary consists of several properties consolidated to form a 14 kilometres (8.7 mi) corridor between the Walyunga and Avon Valley National Parks.
Since then areas previously cleared have been subject to a rehabilitation program, and walking tracks constructed for public use.
[2] Most of the reserve is dominated by wandoo and powderbark woodlands, with extensive areas of heathland and some patches of jarrah and marri forest.
[3] Significant mammal species present are chuditch and honey possum, while an important bird is Carnaby's black-cockatoo.
In collaboration with CALM, and with an ongoing program to control exotic predators such as foxes, various native mammals that would have occurred on Paruna in the past are being successfully reintroduced.
