Regional ecosystem details for 5.5.5

Regional ecosystem 5.5.5
Vegetation Management Act class Least concern
Wetlands Not a Wetland
Biodiversity status No concern at present
Subregion 4, (5), (6)
Estimated extent1 Pre-clearing 22000 ha; Remnant 2021 22000 ha
Short description Acacia sibirica +/- Eucalyptus spp. +/- Corymbia spp. open shrubland on crests and tops of sandstone ranges
Structure code Open Shrubland
Description Acacia sibirica may occur in pure stands, but is frequently associated with Hakea collina in forming a diffuse low shrub layer with sparse canopy cover. Eucalyptus exserta (rarely) and Corymbia blakei are frequent emergents above the canopy. Other low shrubs may be present, but are only locally abundant. Scattered grasses and forbs form a sparse ground cover. Occurs on flat to gently undulating crests and upper slopes of dissected residuals. Slopes range from 1 to 3%. Soils very shallow, acidic, loam and clay-loam lithosols, overlying weathered and altered Cretaceous Winton Formation rocks. Exposed rock covers large areas; ironstone gravel often occurs at the surface. Not a Wetland. (BVG1M: 24a).

Fire management guidelines SEASON: Wet season. INTENSITY: Low - moderate. INTERVAL: Fire return interval not relevant. INTERVAL_MIN: 100. INTERVAL_MAX: 100. STRATEGY: Aim to exclude fire by fuel reduction in adjacent vegetation communities where possible. Undertake partial burns when necessary to reduce fuel loads and protect against severe wildfire. Burn with high soil moisture (i.e., after rain/storms) or in winter when fire is more easily controlled.
