Brigalow

I wish you would then take some pains to travel in the direction of my track from the head of Cùnno through the Brigalow, which is comparatively open, in the direction of my bivouac of 11th September.

Acacia dominated woodlands common in the Desert Uplands region of the Mitchell Grass Downs and in the Brigalow tropical savannas to the south are largely absent from the region, accompanied by a marked transition between the basaltic southern Einasleigh Uplands to the Permian and Tertiary deposits of the Desert Uplands.

Brigalow vegetation is found to the east, and gidgee (A. cambagei) woodlands or shrublands are scattered across the region on alluvium or other more fertile clay soils.

Locally this region contrasts sharply with the eucalypt and brigalow (Acacia harpophylla) woodlands on more fertile soils and less arid climate of the Brigalow Belt to the east and the clay plains of the Mitchell Grass Downs to the north.

Flow-on effects of land degradation in the Einasleigh Uplands could negatively impact downstream habitats in the Brigalow tropical savannas, Queensland tropical rain forests, and Carpentaria tropical savannas ecoregions.

Brigalow naturally covered around 40 percent of the region.

At a local bioregional level the Brigalow Belt is often separated into two regions to differentiate between areas of tropical summer rains and warm year round temperatures in the north, and areas subject to cooler winter temperatures and less extreme summer rainfall dominance in the south.

Dichanthium dominated grasslands within the Brigalow Belt also represent communities distinct from those found in much more extensive grasslands further west.

Brigalow is replaced by gidgee (Acacia cambadgei) in drier areas, generally becoming dominant in the west of the region.
