The rugged, mulga-clad Byngnano Range is dissected by colourful gorges, rockpools and creek beds lined with red gums.

In 1979, the Foundation for National Parks & Wildlife purchased and fenced 100 square kilometres (39 sq mi), in the Coturaundee Ranges, now part of Mutawintji National Park, for the conservation and protection of the yellow-footed rock wallaby.

Follow-up funding of fox eradication in the reserve ensured the survival of this last population of yellow-footed rock-wallabies in New South Wales.

Of the wild animals, wedge-tailed eagle, peregrine falcon, short-billed correllas, zebra finches, budgerigars, apostle birds and magpies can also be found here.
