Access is limited to educational activities by schools and colleges, and research activities which are relevant to the management of the park and compatible with conservation policies.

Environment

Geography

The Mallee Cliffs National Park preserves the original clay red plains of south west New South Wales, protecting extensive areas of flat to undulating sandy red plains and linear sand dunes formed during arid periods from 350,000 to 500,000 years ago.

Flora

The park preserves undisturbed tracts of mallee vegetation, and

trees and shrubs with many small stems and thick underground roots that retain water. Before irrigation farming began, dense thickets of mallee characterized most of northwestern Victoria, and areas of south-western New South Wales. The park contains an important representation of mallee communities, including both bull mallee and whipstick mallee. These flora types are continuing to be extensively cleared on private property for grazing both immediately outside the park and throughout the country. The park contains a number of isolated, relict plant communities that demonstrate shifts in the pattern of vegetation arising from long-term environmental change. In January 1975 a

. The park is the only reserve in New South Wales with malleefowl habitat. The malleefowl is found in arid areas only where the mallee grows. The males build a nest for the eggs by digging a large pit in winter and filling it with leaves and grass over the next four months. The female lays one egg per day for several days in the spring. The male then covers the resulting mound with sand. As the
