| Short description | Acacia shirleyi +/- Acacia catenulata +/- Acacia aneura +/- Acacia cyperophylla var. cyperophylla low woodland on scarps and crests of residuals |
| Structure code | Low Woodland |
| Description | Acacia shirleyi low woodland, common co-dominants include Acacia catenulata, Acacia cyperophylla var. cyperophylla and Acacia aneura. Acacia shirleyi usually predominates with Acacia catenulata dominating in patches. Occasional scattered Eucalyptus spp. and Acacia cyperophylla var. cyperophylla, especially along drainage areas. Hakea collina, Acacia sibirica and Eremophila latrobei are frequently present, and may form an open low shrub layer. The ground layer is sparse, consisting of scattered grasses and forbs. Exhibits very patchy dominance pattern in woody species. Occurs most extensively on crests and scarps of deeply weathered Cretaceous and Tertiary sediments. Soils shallow, stony lithosols and shallow red earths. Not a Wetland. (BVG1M: 24a). |

| Special values | 5.7.1: Habitat for yellow footed rock wallaby Petrogale xanthopus celeris. |
| 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 | 5.7.1: Winton plateau, Goneaway tableland in central-east. |
