| Short description | Eremophila mitchellii open woodland on alluvial plains |
| Structure code | Low Open Woodland |
| Description | Eremophila mitchellii low open woodland. Emergent isolated Grevillea striata or Corymbia tessellaris or C. dallachiana may occur. Occasional shrubs of Vachellia bidwillii, Carissa ovata or Grevillea striata may occur. There may be a ground layer of Enchylaena tomentosa and Sporobolus spp. or Fimbristylis spp. Usually the ground layer is sparse or bare. Occasional grasses include Oxychloris scariosa, Eragrostis spp., and Aristida spp. Occurs on older floodplain complexes on Cainozoic alluvial plains. Common soils are yellow podsols and grey clays or sandy loams over heavy clays. Not a Wetland. (BVG1M: 26a). |

| Fire management guidelines | SEASON: Primarily early dry season mild conditions. Some storm or late burns can be beneficial for rubbervine control. INTENSITY: Low to moderate. INTERVAL: 5-10 years. INTERVAL_MIN: 5. INTERVAL_MAX: 10. STRATEGY: A predominance of early dry season fires is recommended, although there is value in occasional late dry season fires, or storm burns, over small areas for rubbervine control. ISSUES: These Eremophila mitchellii dominated woodlands with scattered eucalypts are fairly tolerant of low to moderate intensity fires. Rubbervine infestations are common, with repeated fires valuable for its control. |
| Comments | 11.3.33: The ecology of Eremophila mitchellii is well studied (Beeston and Webb 1977). This RE appears to be closely related to adjacent Acacia tephrina (RE 11.3.34) or Grevillea striata (RE 11.3.13) communities, and may grow in close association with them in some locations. Extensively cleared for cropping or modified by total grazing pressure. |
