Regional ecosystem details for 9.8.6

Regional ecosystem 9.8.6
Vegetation Management Act class Least concern
Wetlands Not a Wetland
Biodiversity status Of concern
Subregion 5, 4.6, (2.5), (4.5), (10.1)
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.
