| Short description | Eucalyptus coolabah, E. populnea open woodland on alluvium |
| Structure code | Open Woodland |
| Description | Eucalyptus coolabah open woodland, occasionally with E. populnea. A secondary tree or shrub layer commonly occurs, including Eremophila bignoniiflora, Maireana aphylla and Eremophila polyclada or, in the wetter channels, Duma florulenta and Chenopodium auricomum. The ground layer is variable and composed mainly of forbs and varies seasonally. The dominant species include the perennial grasses Eragrostis setifolia +/- Astrebla elymoides and A. lappacea. Frequent or seasonally prominent grasses include Dichanthium sericeum, Panicum decompositum, Dactyloctenium radulans and Iseilema membranaceum. Seasonally abundant and frequently occurring forbs include Brachyscome whitei, Calotis hispidula, Daucus glochidiatus, Goodenia fascicularis, Ipomoea lonchophylla and Plantago drummondii. Occurs on low lying broad drainage depressions on flat alluvial plains, which are subject to seasonal flooding. Associated soils are often deep, strongly alkaline, grey cracking clays with weakly self-mulching surfaces. Not a Wetland. (BVG1M: 16c). |

| Protected areas | Currawinya NP |
| Special values | 6.3.9: High fauna diversity, particularly mammal and bird species. |
| 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. 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 | 6.3.9: Has been subjected to extensive clearing and/or disturbance. |
