Estimated percentage landcover for vegetation class

Structure

Open eucalypt and pine woodland with scattered shrubs and a sparse groundcover

Trees

Eucalyptus intertexta predominates with E. populnea confined to lower slopes in the west, while E. viridis, E. dwyeri, E. vicina, E. sideroxylon (deeper soils) and Brachychiton populneus ssp. trilobus become more common in the east and Callitris glaucophylla is found throughout

Shrubs and vines

Acacia doratoxylon, A. deanei, A. decora, A. lineata, A. hakeoides, A. pravifolia, Geijera parviflora, Exocarpos aphyllus, Dodonaea lobulata, D. heteromorpha, D. viscosa, Leptospermum divaricatum, Beyeria viscosa, Grevillea floribunda, Cassinia laevis, Calytrix tetragona, Melichrus urceolatus, Platysace lanceolata with Casuarina pauper, Alectryon oleifolius ssp. canescens, Eremophila mitchellii in the western part of the range and on basalt hills in the north

Forbs, graminoids and pteridophytes

Aristida jerichoensis, Enteropogon acicularis, Austrostipa scabra, Austrodanthonia setacea, Cheilanthes austrotenuifolia, Gonocarpus elatus, Dianella revoluta

Habitat

Sandy loams derived from sandstones and conglomerates on rocky hills and ranges reiving less than 550 mm rainfall annually, with variants on basalt hills in the northern part of the range

Distribution

Scattered on the western slopes and edge of the plains north from Griffith district to Brewarrina and Bourke, east to Forbes. Probably restricted to NSW.

Notes

Grades into Western slopes dry sclerophyll forests with increasing rainfall and locally into Western peneplains woodlands on the footslopes of hills and ranges. Also shares some floristic affinities with Sandplain mallee. Comparatively less depleted than vegetation on flatter terrain.
