| Short description | Acacia aneura +/- Eucalyptus populnea +/- Eremophila gilesii subsp. gilesii tall open shrubland on Quaternary sediments |
| Structure code | Tall Open Shrubland |
| Description | Acacia aneura tall open shrubland with emergent Eucalyptus populnea in the groves. The intergrove supports an open tussock grassland with isolated shrubs. Groved areas support scattered Eucalyptus populnea trees. Scattered low shrubs are present, but rarely form a well-defined layer. The ground layer is open and composed mainly of tussock grasses. Occurs on flat to gently undulating plains of low relief (slopes <2%). The soils are moderately deep to deep, loamy red earths, with slightly acid clay loams grading into neutral light clays containing ironstone shot at depth. Surfaces are hard setting, characteristically with veneers of ironstone shot. Not a Wetland. (BVG1M: 23a). |

| Protected areas | Hell Hole Gorge NP, Currawinya NP, Lake Bindegolly NP |
| 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 | 6.5.14: The groving in this regional ecosystem is often diffuse, as the soils are fairly consistent throughout. Run on areas within this regional ecosystem may support E. populnea woodland (6.5.3). |
