 The park protects a wide range of biomes, including semi-arid woodland, subalpine heath, and eucalypt forests, and provides a habitat for a range of animals, including bats, birds, wallabies, quolls, and the unique red triangle slug ("Triboniophorus graeffei"), which is known to appear after rainfall.Before it was a national park, the area was used largely as grazing land for domestic animals.The conditions in the park are very harsh, but several pioneering families lived there, and remnants of their occupation remain.
