Regional ecosystem details for 5.7.9

Regional ecosystem 5.7.9
Vegetation Management Act class Least concern
Wetlands Not a Wetland
Biodiversity status No concern at present
Subregion 4, 6, 4.4
Estimated extent1 Pre-clearing 15000 ha; Remnant 2021 15000 ha
Short description Aristida spp., Eriachne pulchella open tussock grassland wooded with Eucalyptus spp. +/- Acacia sibirica on undulating tops of dissected tablelands and ranges
Structure code Open Tussock Grassland
Description Aristida contorta, Eriachne pulchella and Eragrostis pergracilis are the most frequent grasses, and usually form a seasonally variable sparse tussock grassland or sparse herbland. Forbs may be common seasonally, but occur infrequently. Low trees and low shrubs occur as very sparsely scattered emergents. Occurs in central region on gently undulating tops of residuals, and in small valleys of dissected low hills and tablelands. Soils very shallow, gravelly, red earths or shallow desert loams with surface ironstone gravel. Not a Wetland. (BVG1M: 31b).

Fire management guidelines SEASON: Various (wet season or winter). 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. ISSUES: Some Acacias can be fire sensitive (e.g., A. shirleyi, A. aneura) and may be killed by high intensity fire. There is rarely enough fuel load to burn in these ecosystems.
