Scattered Eucalyptus spp. emergents may occur, the most frequent being E. crebra , although Corymbia trachyphloia, E. decorticans and E. thozetiana may occur. Scattered tall shrubs may occur. A low shrubby layer is usually conspicuous. The ground layer is usually very sparse and composed of both grasses and forbs. Occurs on crests and ridge tops formed on consolidated, medium to coarse- grained sediments. Eucalyptus decorticans predominates forming a distinct but discontinuous canopy (25-30m high ). Eucalyptus decorticans usually forms pure stands. Acacia shirleyi is the most frequent tall shrub, although other Acacia spp. may be locally dominant. There is usually a low tree or tall shrub layer dominated by species such as Acacia sparsiflora, A. burrowii, Callitris endlicheri, Allocasuarina inophloia, Acacia spp., Eucalyptus tenuipes, Alphitonia excelsa and Petalostigma pubescens . A low shrub layer is not usually present, however where it occurs Acacia spp. and Dodonaea triangularis usually predominate. The ground layer is sparse to open, and dominated by perennial grasses, usually Aristida spp. or Arundinella nepalensis . Occurs on crests, scarps and upper slopes of ranges formed from medium to coarse-grained sediments with shallow soils.
