| Short description | Acacia cyperophylla var. cyperophylla +/- Acacia aneura low woodland on rises, low hills, rocky outcrops and scarps of deeply weathered Tertiary and Cretaceous sediments. |
| Structure code | Low Woodland |
| Description | Acacia cyperophylla var. cyperophylla, +/- Acacia aneura low woodland. Scattered low shrubs are usually present, and frequently form a very sparse low shrub layer. The ground layer is sparse with a variety of ephemeral tussock grasses and forbs occurring infrequently. Triodia pungens frequently dominates the ground layer in the central-east. Occurs mainly on scarps and crests in central-western residuals. Minor outliers on rises, low hills and scarps of deeply weathered Tertiary and Cretaceous sediments. Soils are usually very shallow, gravelly lithosols with exposed deeply weathered rock common. Siliceous gravel and stone usually spread throughout the profile. Not a Wetland. (BVG1M: 24a). |

| Special values | 5.7.12: Potential habitat for NCA listed species: Solanum unispinum. |
| Fire management guidelines | SEASON: Various (wet season or winter). 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. ISSUES: Some Acacias can be fire sensitive (e.g., A. shirleyi, A. aneura) and may be killed by high intensity fire. There is rarely enough fuel load to burn in these ecosystems. |
| Comments | 5.7.12: In the central-east, and Allen's Range south of Winton. |
