| Short description | Eucalyptus coolabah open woodland on clay alluvial plains |
| Structure code | Open Woodland |
| Description | Eucalyptus coolabah open woodland to woodland. A secondary tree or shrub layer may occur, including Eremophila bignoniiflora, Maireana aphylla, Eremophila polyclada and Duma florulenta. The ground layer is seasonally variable, including Eragrostis setifolia, Astrebla spp., Dichanthium sericeum, Panicum decompositum and Aristida spp. Forbs include Brachyscome whitei, Calotis hispidula, Daucus glochidiatus, Goodenia fascicularis, Ipomoea lonchophylla and Plantago drummondii. Occurs on clay alluvial plains of major watercourses. Soils are very deep grey or brown cracking clays with some alluvial texture contrast soils. Not a Wetland. (BVG1M: 16c). Vegetation communities in this regional ecosystem include: 6.3.7x1: Seasonal swamps (wooded). Acacia stenophylla low woodland to low open woodland. A shrub layer, dominated by Duma florulenta, usually occurs. The ground layer is variable, from bare to seasonal forbs. Small areas of Duma florulenta shrubland may occur. Occurs in closed depressions on clay alluvial plains of major watercourses. Cracking clay soils. Palustrine. (BVG1M: 16c). 6.3.7x2: Seasonal swamps (wooded). Eucalyptus coolabah woodland, occasionally with Casuarina cristata, E. ochrophloia and Acacia cambagei. A shrub layer may occur, including Duma florulenta, Eremophila bignoniiflora and Senna spp. The ground layer is variable, with tussock grasses and forbs, including Eragrostis parviflora, Marsilea spp., and Alternanthera spp. Occurs in closed depressions on broad sandy plains overlying clays or alluvium. Brown silty clay to cracking clay soils. Palustrine. (BVG1M: 16c). |
| Supplementary description | Neldner (1984), 47b (34); Mills and Lee (1990), W8 (LU 20); Kingsford et al. (2001), floodplains |
| Protected areas | Binya NP, Culgoa Floodplain NP, Currawinya NP, Narkoola NP, Lake Bindegolly NP |
| Special values | 6.3.7: High fauna diversity. 6.3.7x2: Provides valuable habitat for a high number of fauna species, particularly birds (Kingsford et al. 2001). |
| 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 | 6.3.7: Confined largely to the lower Warrego River floodplain (subregion 5). 6.3.7x2: Previously mapped as 6.3.8x1. |
