[8] In the Hamersley region, mulga woodland occurs on fine-textured valley soils, with Acacia aneura over the grasses Aristida spp.

Snappy gum (Eucalyptus leucophloia) occurs with the grass Triodia brizoides on the skeletal soils of the ranges.

Year-round watercourses and springs support stands of red river gum, (Eucalyptus camaldulensis refulgens), Melaleuca, and the palm Livistona alfredii.

Sheltered gorges along the edge of the Chichester Plateau provide water and protection from fire, and support relict communities of Terminalia, Erythrina, and Ficus.

[9] The Chichester Plateau is principally scrub steppe, with the shrub Acacia inaequilatera and the bunch grass Triodia wiseana.
