| Short description | Eucalyptus coolabah +/- Casuarina cristata woodland on alluvial plains |
| Structure code | Woodland |
| Description | Eucalyptus coolabah woodland to open woodland, commonly with scattered or clumped Casuarina cristata. Scattered tall shrubs or low trees may occur, including Acacia pendula (may be locally dominant), Alectryon oleifolius, Eremophila bignoniiflora, Acacia omalophylla and Atalaya hemiglauca. Duma florulenta may be present as a low shrub in wetter areas. The ground layer is open to moderately dense and usually dominated by grasses. Forbs may be conspicuous after winter rains or flooding. In some areas, Astrebla lappacea and Sclerolaena muricata form zones of dominance in the ground layer. Occurs on alluvial plains and swamps, subject to flooding . Associated with deep (> 150 cm), grey and brown, cracking clay soils. The soils are neutral to slightly alkaline at the surface, becoming strongly alkaline below 60 cm depth. Not a Wetland. (BVG1M: 16c). |

| Fire management guidelines | INTERVAL: Fire return interval not relevant. INTERVAL_MIN: 100. INTERVAL_MAX: 100. STRATEGY: Manage surrounding country. ISSUES: This community does not need fire. Flood events drive recruitment of coolabah. Hollow trees are critical habitat. High intensity and extensive fires will degrade vegetation structure and destroy animal habitats. Restrict extent and intensity of fires. |
| Comments | 11.3.28: Casuarina cristata has been selectively thinned in some areas leaving an Eucalyptus coolabah open woodland. |
