| Short description | Acacia cyperophylla var. cyperophylla +/- Acacia cambagei or Acacia georginae +/- Atalaya hemiglauca tall shrubland on drainage lines |
| Structure code | Tall Shrubland |
| Description | Acacia cyperophylla var. cyperophylla tall shrubland with Acacia cambagei and/or Acacia georginae frequent codominants, Atalaya hemiglauca is usually present as scattered tall shrubs. Eucalyptus coolabah or Eucalyptus camaldulensis may occur as scattered trees in some drainage lines. Low shrubs are frequently present, but only rarely is a conspicuous low shrub layer of Senna artemisioides subsp. oligophylla and/or Eremophila freelingii formed. The ground layer varies from sparse to open, and is usually dominated by Eulalia aurea, Themeda triandra, Eriachne mucronata and Enteropogon acicularis. Scattered forbs and sub shrubs are also commonly present. Occurs on smaller drainage lines associated with dissected tablelands and residuals and adjoining undulating plains. Soils variable depending on position, but mainly deep, gravelly, sandy clay loams in upper drainage lines, and deep, gravelly, red clays lower in landscape. Not a Wetland. (BVG1M: 24a). |

| 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. |
