Short description Acacia aneura, Eucalyptus populnea low woodland on run-on plains
Structure code Low Woodland
Description Acacia aneura low woodland, with scattered Eucalyptus populnea emergents. Shrub layers are usually absent, although scattered Eremophila gilesii subsp. gilesii may be present. In the groves the ground stratum is sparse to open and dominated by Cheilanthes sieberi and perennial grasses Digitaria breviglumis or Aristida calycina var. praealta. In the intergrove areas the ground layer is open to dense and dominated by grasses. The perennial grasses Aristida calycina var. praealta, A. jerichoensis and Themeda triandra may be abundant while Monachather paradoxus, Thyridolepis mitchelliana, Urochloa piligera, Digitaria hystrichoides, D. brownii and Eragrostis lacunaria occur frequently. A variety of forbs may be seasonally abundant including Euphorbia drummondii, Plantago drummondii, Sida fibulifera, Vellea glabrata and Vittadinia spp. Occurs on very gently sloping plains (run-on areas). Associated soils are moderately deep loamy red earths with hard setting surfaces. Not a Wetland. (BVG1M: 23a).

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: Acacia aneura may be killed by high intensity fire. There is rarely enough fuel load to burn in these ecosystems.
Comments 6.5.6: This regional ecosystem shows a highly modified structural and floristic composition which varies with past disturbance history.
