Short description Acacia cambagei low woodland on Tertiary clay deposits and shallow clay depressions on plateau surfaces
Structure code Low Woodland
Description Acacia cambagei low woodland. A shrub layer dominated by A. cambagei commonly occurs. The ground layer is sparse tussock grasses, including Aristida latifolia, Enneapogon spp. and Sporobolus australasicus. Occurs on Tertiary high-level alluvial clay deposits and shallow clay depressions on lateritic plateau surfaces. Yellow to brown clay soils, commonly gravelly. Not a Wetland. (BVG1M: 26a).

Vegetation communities in this regional ecosystem include:
2.4.3a: Acacia cambagei low woodland. A shrub layer dominated by A. cambagei commonly occurs. The ground layer is sparse tussock grasses, including Aristida latifolia, Enneapogon spp. and Sporobolus australasicus. Occurs on undulating, Tertiary high-level alluvial clay deposits, commonly gravelly. Orange to brown clay soils. Not a Wetland. (BVG1M: 26a).
2.4.3b: Acacia cambagei low woodland. A shrub layer dominated by Acacia cambagei commonly occurs. The ground layer is sparse tussock grasses. Occurs on exposures of clay deposits in shallow depressions on lateritic plateau surfaces. Yellow-brown clay soils. Not a Wetland. (BVG1M: 26a).
Fire management guidelines INTERVAL: Fire return interval not relevant. INTERVAL_MIN: 100. INTERVAL_MAX: 100. STRATEGY: Do not burn deliberately. Manage surrounding fire-adapted areas to create landscape mosaic of burnt and unburnt to mitigate against impact of wildfires. ISSUES: Vulnerable to repeated, high intensity fires. Sparse tussock grass fuel loads should protect these communities. The invasive grass buffel draws fires into Acacia communities to the detriment of these communities. Fire plays no role in regeneration of gidgee.
Comments 2.4.3: Subject to clearing for pasture development and to loss of ground cover due to high total grazing pressures. 2.4.3a: Was previously mapped as 2.9.4x41a. Subject to clearing for pasture development and to loss of ground cover due to high total grazing pressures. 2.4.3b: Was previously mapped as 2.9.4x41b. 2.9.5 has been amalgamated into 2.4.3b and 2.3.7a.

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.
