Description

This community occurs north of Bourke between the Culgoa and Warrego Rivers on soft red earths and heavy grey clays on level to slightly undulating plains. The structure of Brigalow-Gidgee ranges from woodland to shrubland and scrub depending on local conditions. The canopy is dominated by either Brigalow Acacia harpophylla or Gidgee Acacia cambagei with the other species being co-dominant or part of the shrub layer, depending on site disturbance.

For a detailed list of the vascular plants that characterise this community see the Scientific Determination (link in right hand box on this page).

Belongs to the 'Brigalow Clay Plain Woodland' vegetation class of Keith (2002, 2004).

The community has been extensively modified with at least 79% of the estimated original 190,000 ha cleared or thinned. Brigalow-Gidgee EEC has been mapped on Culgoa National Park and on Ledknapper Nature Reserve.
