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