Short description Acacia cambagei woodland on Cainozoic clay plains
Structure code Woodland
Description Acacia cambagei woodland to open forest. A secondary tree layer commonly occurs, including Lysiphyllum carronii, Geijera parviflora, Acacia harpophylla, A. argyrodendron, Terminalia oblongata and Eremophila mitchellii. A shrub layer may occur, including Carissa ovata, Capparis lasiantha, Eremophila deserti, Capparis anomala and Alectryon diversifolius. The ground layer is sparse to open and dominated by tussock grasses. Occurs on gently undulating plains formed from Cainozoic sediments. Associated soils are texture contrast with thin sandy or loamy surface horizons and strongly alkaline clay subsoils. Not a Wetland. (BVG1M: 26a).

Fire management guidelines INTERVAL: Fire return interval not relevant. INTERVAL_MIN: 100. INTERVAL_MAX: 100. STRATEGY: Do not target for fires. Can tolerate only very early dry season fires, under mild conditions, that trickle along the ground layer. Control fuel loads in the surrounding vegetation. ISSUES: Gidgee and Brigalow are only tolerant of mild fires trickling underneath, and can be damaged or killed by moderate to high intensity fires. Exotic grasses, such as Buffel grass, carry intense fires into these communities and can cause tree deaths. Ensure no damage to Acacia trees from fires.
Comments 11.4.6: Extensively cleared for pasture.

1 Estimated extent is from version 13.1 pre-clearing and 2021 remnant regional ecosystem mapping. Figures are rounded for simplicity. For more precise estimates, including breakdowns by tenure and other themes see remnant vegetation in Queensland.
