| Short description | Eucalyptus chlorophylla +/- Terminalia spp. woodland on Cretaceous mudstone footslopes and plains. |
| Structure code | Woodland |
| Description | Eucalyptus chlorophylla woodland, commonly with Terminalia spp. Corymbia dallachiana may occur in the canopy. A lower tree or shrub layer may occur, including Erythrophleum chlorostachys, Dendrolobium arbuscula and Carissa lanceolata. The ground layer is tussock grasses, including Heteropogon contortus, Chrysopogon sp. and Bothriochloa bladhii. Occurs on footslopes, rises and undulating plains of Cretaceous mudstones. Yellow to brown clays. Not a Wetland. (BVG1M: 18c). Vegetation communities in this regional ecosystem include: 2.9.7a: [RE not in use]²: This vegetation community has been amalgamated into 2.9.7. Eucalyptus chlorophylla woodland, commonly with Terminalia spp. Corymbia dallachiana may occur in the canopy. A lower tree or shrub layer may occur, including Erythrophleum chlorostachys, Dendrolobium arbuscula and Carissa lanceolata. The ground layer is tussock grasses, including Heteropogon contortus, Chrysopogon sp. and Bothriochloa bladhii. Occurs on footslopes, rises and undulating plains of Cretaceous mudstones. Yellow to brown clays. Not a Wetland. (BVG1M: 18c). 2.9.7b: [RE not in use]²: This vegetation community is now mapped as 2.9.10. Eucalyptus leptophleba, Corymbia terminalis, C. erythrophloia and C. dallachiana open woodland to woodland, occasionally with E. chlorophylla or E. microneura in the canopy. A shrub layer of Dendrolobium arbuscula may occur. The ground layer is commonly Heteropogon contortus and Themeda spp. Occurs on undulating rises and lowlands on Cretaceous mudstones. Yellow to brown clay soils, occasionally with exposed calcareous concretions. Not a Wetland. (BVG1M: 18c). |

| Fire management guidelines | SEASON: Early to mid-dry season. INTENSITY: Low to moderate. INTERVAL: 1-5 years. INTERVAL_MIN: 1. INTERVAL_MAX: 5. STRATEGY: Burn less than 30% in any year. Maintaining a fire mosaic will ensure protection of animal habitats and mitigate against wildfires. ISSUES: Moisture retention means that these flats need burning later in the year than surrounding vegetation, so perimeter burns are advisable. |
| Comments | 2.9.7: More information required to confirm conservation status. Extensive pasture development has occurred in area and subject to loss of ground cover due to high total grazing pressures. 2.9.7b: Commonly invaded by *Themeda quadrivalvis (grader grass). |
1 Estimated extent is from version 13 pre-clearing and 2021 remnant regional ecosystem mapping. Figures are rounded for simplicity. For more precise estimates, including breakdowns by tenure and other themes see remnant vegetation in Queensland.
2 Superseded: Revision of the regional ecosystem classification removed this regional ecosystem code from use. It is included in the regional ecosystem description database because the RE code may appear in older versions of RE mapping and the Vegetation Management regulation.
