|---|---|
| Vegetation Management Act class | Least concern |
| Wetlands | Not a Wetland |
| Biodiversity status | Of concern |

| Estimated extent1 | Pre-clearing 63000 ha; Remnant 2021 62000 ha |
| Short description | Acacia cambagei low open forest on scree slopes and footslopes of basalt tablelands |
| Structure code | Low Open Forest |
| Description | Low open forest to low woodland of Acacia cambagei (gidgee) +/- Denhamia oleaster +/- Atalaya hemiglauca (whitewood) +/- Acacia crombiei (pink gidgee). There is generally no shrub layer but scattered juvenile Acacia cambagei and other species may occur. There is a sparse to mid-dense ground layer of tussock grasses. Acacia crombiei may dominate in some places. Occurs on scarps and margins of basalt tablelands and their associated footslopes in the south-west of the bioregion. Soils are skeletal with basalt boulders common. Not a Wetland. (BVG1M: 26a). |
| Protected areas | Porcupine Gorge NP |
| Special values | 9.8.6: Habitat for the vulnerable plant species Acacia crombiei. |
| Fire management guidelines | INTERVAL: 10-50 years generally following periods of high rainfall and sufficient grass growth. INTERVAL_MIN: 10. INTERVAL_MAX: 50. 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 is 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. |
| Comments | 9.8.6: Occurs in the south-west of the bioregion. |
