 Bushwalkers accessing the remote central and southern sections of the park's moist subtropical rainforest will find a mix of corkwood, sassafras ("Doryphora sassafras"), large tree ferns ("Dicksonia") and silver sycamore ("Cryptocarya glaucescens").The park also protects threatened species such as the koala, tiger quoll, sugar glider, yellow-bellied glider, superb lyrebird, boobook owl, sooty owl, powerful owl, tawny frogmouth and parma wallaby.This region and its escarpment served as the boundary between the Nganyaywana people of the Northern Tablelands and the Danggati who had the hinterland valleys leading up to the tableland.
