| Short description | Eucalyptus leucophloia low open woodland on lateritic plateaus and residuals |
| Structure code | Low Open Woodland |
| Description | Eucalyptus leucophloia low open woodland with a ground layer dominated by Triodia spp. Occurs on lateritic plateaus and residuals with shallow, gravelly loamy lithosol soils and frequent rock outcrops. Not a Wetland. (BVG1M: 19a). Vegetation communities in this regional ecosystem include: 4.7.8a: Eucalyptus leucophloia low open woodland, occasionally with Acacia cambagei, E. normantonensis and A. aneura. Acacia chisholmii shrubs may occur. Triodia spp. commonly dominate the ground layer. Occurs on lateritic residuals and plateaus derived from deeply weathered Cretaceous mudstones. Skeletal soils. Not a Wetland. (BVG1M: 19a). 4.7.8b: Eucalyptus leucophloia low open woodland, occasionally with Acacia cambagei and E. normantonensis. Acacia chisholmii shrubs may occur. Triodia spp. commonly dominate the ground layer. Occurs on deeply weathered Cambrian shale residuals, commonly overlying limestones. Skeletal soils. Not a Wetland. (BVG1M: 19a). 4.7.8c: [RE not in use]²: This vegetation community is now mapped as 4.7.7b. Eucalyptus leucophloia and/or E. normantonensis and/or E. odontocarpa low open woodland, occasionally with E. gamophylla, Corymbia terminalis and C. aparrerinja. A sparse, mixed shrub layer may occur, including Acacia spp. and Senna spp. The ground layer is commonly dominated by Triodia spp. Occurs on rises and low hills of silcrete, derived from various deeply weathered sediments, including sandstones, conglomerates and shales. Not a Wetland. (BVG1M: 19a). 4.7.8x1: Mixed low open woodland, including combinations of the species Corymbia aspera, Atalaya hemiglauca, Ventilago viminalis and Psydrax oleifolia. Ehretia saligna, Corymbia terminalis and Grevillea striata may occur in the canopy. Scattered shrubs may occur. The ground layer is commonly bare or with sparse tussock grasses and forbs. Occurs on flat tops and scarps of lateritised Tertiary sandstone and siltstone (Edkins Formation). Not a Wetland. (BVG1M: 19a). |

| Fire management guidelines | SEASON: During the wet season to early dry season while soil retains moisture. INTENSITY: Low to moderate. Spinifex communities may naturally burn with a higher severity in some areas. INTERVAL: Broad fire interval range 10-15 years. INTERVAL_MIN: 10. INTERVAL_MAX: 100. STRATEGY: Apply mosaic across the landscape at a range of frequencies to create varying stages of post-fire response. Ensure some areas are left long unburnt (>15 years) but not so they promote wildfire. Mosaic 20-60% burn. ISSUES: Wet season burning can be undertaken as a series of small burns throughout the wet season. |
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.
