| Regional ecosystem | 6.5.8 |
|---|---|
| Vegetation Management Act class | Least concern |

| Short description | Acacia aneura, Eucalyptus populnea +/- Eremophila gilesii subsp. gilesii low woodland on undulating plains in the west |
| Structure code | Low Woodland |
| Description | Acacia aneura low woodland with emergent Eucalyptus populnea. A prominent shrub layer commonly occurs. The ground layer is dominated by tussock grasses and varies in composition with the tree density. At high tree densities, Thyridolepis mitchelliana, Eragrostis lacunaria and Digitaria hubbardii usually dominate. As density decreases, Aristida calycina var. praealta and A. jerichoensis become dominant. Occurs on flat to gently undulating plains formed from superficial Quaternary deposits over the Tertiary land surface in the west of the bioregion. Associated soils are deep to very deep, acid to neutral, loamy red earths with ironstone gravel in the profile. Soils are massive and hard setting when dry but some accumulation on the surface. Not a Wetland. (BVG1M: 23a). |

| Protected areas | Currawinya NP, Lake Bindegolly NP, Welford NP |
| Special values | 6.5.8: Potential habitat for NCA listed species: Hydrocotyle dipleura. |
| 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 | 6.5.8: Highly modified structural and floristic composition. Occurs widely across western parts of the bioregion. |
