Flats, rolling downs and upper outwash areas with deep clay soils


Upper floodplains north from Narrabri, and north from Bourke, extending into central Qld.


These woodlands define the 'brigalow belt', stretching from central Qld and reaching its southern limit in north-west NSW. Composition varies with soil texture and rainfall, with western occurrences north of Bourke having more arid floristic elemants than those north of Narrabri. Related vegetation includes Western peneplain woodlands and Northwest plains semi-arid shrublands. Severely depleted and degraded by pastoral activities. Remnant stands are small and sometimes affected by weeds or soil degradation.
