| Regional ecosystem | 5.5.2 |
|---|---|
| Vegetation Management Act class | Least concern |
| Wetlands | Not a Wetland |

| Short description | Acacia aneura low open woodland +/- Acacia sibirica +/- Eremophila latrobei on Quaternary deposits |
| Structure code | Low Open Woodland |
| Description | Acacia aneura usually predominates forming a distinct but very discontinuous canopy in distinct groves. Isolated trees emerge above the canopy. There is a distinct shrub layer of Acacia sibirica which is codominant or occasionally dominant. Other scattered low shrubs occur frequently. The ground layer is sparse and composed of grasses and forbs. Occurs on slightly undulating to undulating plains with slopes of less than 3% associated with the tops of dissected residuals. Soils shallow to very shallow, loamy red earths and lithosols with silcrete stone frequent on the soil. Not a Wetland. (BVG1M: 23b). |

| Protected areas | Goneaway NP, Welford NP |
| Special values | 5.5.2: Habitat for threatened plant species including Grevillea kennedyana. |
| 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. |
| Comments | 5.5.2: Sheet erosion and associated change in ground layer floristic composition locally common (Wilson and Purdie, 1990b; H1). |
