[4] The park is closed to the public as part of an ongoing policy to protect malleefowl and other threatened animals, and to assist in meeting other conservation objectives.

Before irrigation farming began, dense thickets of mallee characterized most of northwestern Victoria, and areas of south-western New South Wales.

The park contains a number of isolated, relict plant communities that demonstrate shifts in the pattern of vegetation arising from long-term environmental change.

[4] In January 1975 a bushfire ravaged the region which later became national park, making the average age of the vegetation considerably younger than similar protected areas.

This makes the park a less attractive option for release of certain animals such as the black-eared miner, which use older trees and mallee bushes as habitat.

[5] The park lies within the Southern NSW Mallee Important Bird Area, identified by BirdLife International as supporting a significant population of the vulnerable malleefowl.
