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. |
1 Estimated extent is from version 13.1 pre-clearing and 2021 remnant regional ecosystem mapping. Figures are rounded for simplicity. For more precise estimates, including breakdowns by tenure and other themes see remnant vegetation in Queensland.
