Summary The mosaic of sandstone heath and eucalypt woodlands supports large numbers of the endangered Eastern Bristlebird, and smaller numbers of the restricted-range Rockwarbler and Pilotbird.
Site description The heathland of Barren Grounds, Budderoo and Red Rocks is one of only four large areas of heath along this section of coast. The heaths and sedgelands of the plateau grade into warm temperate rainforest and subtropical rainforest on the slopes, gullies and ridges below the escarpment. The area is a typical hanging swamp plateau, dominated by heathland and almost completely encircled by sheer cliffs. Red Rocks is a nearby area of heath and this IBA may warrant expansion if Bristlebirds establish themselves in other pockets of habitat in the vicinity. The climate is temperate with damp winters and warm, humid summers moderated by proximity to the coast.

Other biodiversity Threatened species include the Tiger Quoll, Dasyurus maculatus, Long-nosed Potoroo, Potorous tridactylus, Common Bent-wing Bat, Miniopterus schreibersii, Red-crowned Toadlet, Pseudophryne australis, Giant Barred Frog, Mixophyes iteratus or M. balbus, and Giant Burrowing Frog, Heleioporus australiacus. The Broad-headed Snake, Hoplocephalus bungaroides, is also likely to occur. A rare, undescribed species of frog, Litoria sp., similar to the Jervis Bay Tree Frog, Litoria jervisiensis, has been recorded in heath at Barren Grounds.
Protection status The IBA contains Barren Grounds Nature Reserve and significant portions of Budderoo National Park and Cambewarra Range Nature Reserve.
