| Short description | Acacia brachystachya, A. aneura open shrubland on the lower slopes of lateritic residuals |
| Structure code | Open Shrubland |
| Description | Acacia brachystachya open shrubland, occasionally with Acacia clivicola. A. aneura is usually present as an emergent. Isolated low trees and other low shrubs may occur. The ground layer is very sparse, and composed of grasses and forbs. Occurs on gently undulating plains and lower slopes of scarp retreats associated with dissected lateritic tablelands. The soils are shallow to very shallow, red, loam to clay-loam lithosols with much silcrete stone in the profile. Silcrete stones and boulders are spread throughout. Exposed rock is often present. Not a Wetland. (BVG1M: 24a). |

| Protected areas | Currawinya NP |
| Special values | 6.7.15: Potential habitat for NCA listed species: Rhaphidospora bonneyana. |
| 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: Some Acacias can be fire sensitive (A. shirleyi, A. aneura) and may be killed by high intensity fire. There is rarely enough fuel load to burn in these ecosystems. |
| Comments | 6.7.15: Acacia brachystachya was formerly known as Acacia ciboria in this region. This regional ecosystem can grade into an Acacia aneura, A. stowardii tall open shrubland in places. |
