| Short description | Acacia aneura, and/or Acacia sibirica tall shrubland to low woodland on Quaternary sand sheets and dune fields |
| Structure code | Tall Shrubland |
| Description | Acacia aneura, and/or Acacia sibirica tall shrubland to low woodland on Quaternary sand sheets. Either Acacia aneura and/or Acacia sibirica forms a distinct canopy. Isolated trees such as Corymbia terminalis or Corymbia blakei may occur emerging above the canopy. Low shrubs are conspicuous forming a well defined layer in places. The ground flora is variable composed of grasses and forbs. Occurs on flat to gently undulating plains usually in run-on situations formed from Quaternary deposits overlying alluvium or Tertiary land surface. Associated soils are moderately deep to deep red earths with accumulations of loose sand on normally hard setting surface. Not a Wetland. (BVG1M: 23b). Vegetation communities in this regional ecosystem include: 5.5.3a: Acacia sibirica predominates forming a distinct but discontinuous canopy layer. Usually Acacia aneura is present. Isolated trees such as Corymbia terminalis or Corymbia blakei may occur emerging above the canopy. Low shrubs are conspicuous forming a well defined layer in places. The ground flora is variable composed of grasses and forbs. Occurs on flat to gently undulating plains usually in run-on situations formed from Quaternary deposits overlying alluvium or Tertiary land surface. Associated soils are moderately deep to deep red earths with accumulations of loose sand on normally hard setting surface. Not a Wetland. (BVG1M: 23b). 5.5.3b: Acacia aneura low woodland. Acacia aneura predominates forming a distinct canopy layer. Isolated trees such as Corymbia terminalis or Corymbia aparrerinja may occur in the canopy or emerging above. Low shrubs are inconspicuous or absent. The ground flora is variable composed of grasses and forbs including Eragrostis basedowii. Occurs on flat to gently undulating sand plains and dune fields usually in run-on situations formed from Quaternary deposits overlying alluvium. Normally associated with the edge of flood plains. Associated soils are moderately deep to deep red earths with accumulations of loose sand on normally hard setting surface. Not a Wetland. (BVG1M: 23b). |

| Fire management guidelines | SEASON: Wet season. 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 when fire is more easily controlled. |
| Comments | 5.5.3b: Predominantly in the vicinity of the Cooper floodplain. |
