Regional ecosystem 2.5.34
Vegetation Management Act class Least concern
Wetlands Not a Wetland
Biodiversity status No concern at present
Subregion 8, 2, (1.3), (3), (4.5)
Estimated extent1 Pre-clearing 115000 ha; Remnant 2021 110000 ha
Short description Acacia cambagei low woodland on gravelly deposits and deeply weathered surfaces
Structure code Low Woodland
Description Acacia cambagei low woodland to low open woodland. A sparse shrub layer may occur, including A. cambagei, Atalaya hemiglauca and Carissa lanceolata. The ground layer is sparse tussock grasses. Occurs on gravelly, old alluvial and residual deposits and plains and rises derived from deeply weathered siltstones. Yellow to brown texture contrast soils and clays. Not a Wetland. (BVG1M: 26a).

Vegetation communities in this regional ecosystem include:
2.5.34a: Acacia cambagei low woodland, occasionally with Lysiphyllum cunninghamii and Atalaya hemiglauca. A sparse shrub layer may occur, including canopy species and Carissa lanceolata. The ground layer is sparse tussock grasses. Occurs on old, dissected high-level alluvial and Quaternary residual deposits (commonly gravelly). Red to brown texture contrast soils. Not a Wetland. (BVG1M: 26a).
2.5.34b: Acacia cambagei low woodland. A sparse shrub layer of A. cambagei and Carissa lanceolata may occur. The ground layer is sparse tussock grasses, including Aristida spp., Iseilema spp. and Astrebla spp. Occurs on plains and low rises derived from outwash deposits of lateritised siltstones. Yellow to brown clays (commonly with ferruginous gravel). 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. However, low or discontinuous fuel loads 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 2.5.34: May be invaded by exotic Cenchrus spp. Subject to clearing for grazing. 2.5.34a: Was previously mapped as 2.5.2x1a. May be invaded by exotic Cenchrus spp. Subject to clearing for grazing. 2.5.34b: Was previously mapped as 2.5.2x1c. May be invaded by exotic Cenchrus spp. Subject to clearing for grazing.
