| Description | Corymbia terminalis and/or C. aparrerinja (or C. dallachiana) low open woodland to open forest. Other canopy species may occur, including Eucalyptus leucophylla, Lysiphyllum spp. or Grevillea striata. A shrub layer may occur, including Acacia spp. and Eremophila mitchellii. The ground layer is tussock grasses, including Bothriochloa spp. and Enteropogon acicularis. Occurs on levees of major watercourses. Very deep earthy sands or red earth soils. Not a Wetland. (BVG1M: 19b). Vegetation communities in this regional ecosystem include: 4.3.10a: Mixed low open woodland, with combinations of the species Corymbia terminalis, C. aparrerinja, Eucalyptus coolabah, Acacia cambagei, A. georginae, Atalaya hemiglauca. Hakea chordophylla and Erythrina vespertilio may occur. The ground layer is tussock grasses. Occurs on active levees of major watercourses of the Georgina River catchment extending from the Northwest Highlands bioregion. Red sands and loams. Not a Wetland. (BVG1M: 19b). 4.3.10b: Mixed open woodland, with combinations of the species Corymbia terminalis, C. aparrerinja, Eucalyptus leucophylla and Grevillea striata. Acacia cambagei, E. coolabah and Atalaya hemiglauca commonly occur. The ground layer is tussock grasses. Occurs on sandy and loamy levees of major watercourses. Sandy and loamy soils. Not a Wetland. (BVG1M: 19b). 4.3.10c: Corymbia terminalis and/or C. dallachiana woodland to open forest. Lower trees include Lysiphyllum spp., Grevillea striata, Atalaya hemiglauca and Vachellia sutherlandii. A sparse variable shrub layer may occur. The ground layer is tussock grasses. Occurs on levees of major watercourses in the north-east of the bioregion. Sandy and loamy soils. Not a Wetland. (BVG1M: 19b). 4.3.10x1: Mixed low open woodland to woodland, including combinations of the species Archidendropsis basaltica, Ventilago viminalis, Lysiphyllum gilvum, Acacia cambagei, Eucalyptus coolabah and Atalaya hemiglauca. Occasional canopy species include Eucalyptus populnea, Corymbia terminalis and Flindersia maculosa. A sparse shrub layer may occur, usually with Eremophila mitchellii. The ground layer is tussock grasses. Active levees and Quaternary alluvial plains of major watercourses in the south-east of the bioregion. Not a Wetland. (BVG1M: 27a). |

| Fire management guidelines | SEASON: During the wet season to early dry season while soil retains moisture. INTENSITY: Low to moderate. INTERVAL: Generally too sparse to burn. Interval will depend on need for burning and seasonal conditions. Fire return interval flexible. INTERVAL_MIN: 100. INTERVAL_MAX: 100. STRATEGY: Mosaic burn less than 30% in any year. ISSUES: Ground layer is typically sparse and seasonally variable. Interval will depend on need for burning, seasonal conditions and grazing pressure. |
| Comments | 4.3.10b: 4.5.8b has been amalgamated into this vegetation community. 4.3.10x1: Commonly invaded by Cenchrus ciliaris. |
