| Regional ecosystem | 6.5.18 |
|---|---|
| Vegetation Management Act class | Least concern |
| Wetlands | Not a Wetland |
| Biodiversity status | No concern at present |
| Subregion | 6, 8, (4.4) |
| Estimated extent1 | Pre-clearing 385000 ha; Remnant 2021 223000 ha |
| Short description | Acacia aneura +/- Eucalyptus populnea low woodland on sandy deposits over old lake beds |
| Structure code | Low Open Woodland |
| Description | Acacia aneura low woodland to low open forest. Emergent Eucalyptus populnea may occur. Eremophila mitchellii tall shrubs are usually present, and occasionally form a distinct layer. Eremophila gilesii subsp. gilesii is present and in places forms a conspicuous low shrub layer. The ground layer is open, and composed of grasses and forbs. Occurs on flat to very gently undulating sandy deposits overlying old lake beds. Soils are generally deep, red and brown texture contrast soils with acid, loamy surface soils overlying clay subsoils or moderately deep to deep, massive red earths with sandy loam surface textures and surface crusts. Not a Wetland. (BVG1M: 23a). |

| 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: Acacia aneura may be killed by high intensity fire. There is rarely enough fuel load to burn in these ecosystems. |
| Comments | 6.5.18: This regional ecosystem was described in Sattler and Williams (1999) under 6.4.5 but has now been allocated to land zone 5 following re-assessment. Northern areas subject to clearing and associated introduction of exotic pastures. |
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.
