| 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. |
