Regional ecosystem details for 6.7.2

Regional ecosystem 6.7.2
Vegetation Management Act class Least concern
Wetlands Not a Wetland
Biodiversity status Of concern
Subregion 2, 11.26
Estimated extent1 Pre-clearing 29000 ha; Remnant 2021 12000 ha
Short description Acacia microsperma open forest on upper and footslopes
Structure code Open Forest
Description Acacia microsperma open forest to woodland. Eucalyptus thozetiana may occur in the canopy or as an emergent. A tall shrub layer of Geijera parviflora may be present, and scattered low shrubs usually occur. The ground layer is sparse and dominated by tussock grasses. Occurs on undulating low hills with shallow soils. Not a Wetland. (BVG1M: 24a).

Fire management guidelines SEASON: Various (wet season or winter). INTENSITY: Low to 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. ISSUES: Some Acacias can be fire sensitive (A. shirleyi, A. aneura) and may be killed by high intensity fire. There is rarely enough fuel load to burn in these ecosystems.
Comments 6.7.2: Poor regeneration of Acacia microsperma due to total grazing pressure. Areas of this regional ecosystem on deeper soils have been preferentially cleared.
