| Short description | Eucalyptus leucophylla low open woodland on limestone |
| Structure code | Low Open Woodland |
| Description | Eucalyptus leucophylla low open woodland with a ground layer of Triodia pungens. Occurs on low hills on limestones and calcareous shales; calcareous desert soils, some calcareous red-brown earths and skeletal soils. Not a Wetland. (BVG1M: 19b). Vegetation communities in this regional ecosystem include: 1.9.5a: [RE not in use]²: This vegetation community is now mapped as 1.9.11a. Corymbia terminalis and Lysiphyllum cunninghamii low open woodland. Senna spp. shrub layer may be present. Mixed ground layer dominated by tussock grasses. Includes treeless areas. Occurs on skeletal soils on low stepped hills on Cambrian limestones. Not a Wetland. (BVG1M: 19b). 1.9.5b: Eucalyptus leucophylla open mallee shrubland with a ground layer of Triodia pungens. Occurs on shallow soils overlying limestone. Not a Wetland. (BVG1M: 19b). 1.9.5c: [RE not in use]²: This vegetation community is now mapped as 1.9.12. Hummock grassland of Triodia pungens +/- tussock grasses +/- emergent Corymbia terminalis and Eucalyptus leucophylla. Occurs on shallow soils overlying limestone. Not a Wetland. (BVG1M: 19b). 1.9.5d: [RE not in use]²: This vegetation community is now mapped in part as 1.9.11b and in part as 1.9.11c. Mixed low open woodland including Eucalyptus leucophylla, Eucalyptus pruinosa, Eucalyptus leucophloia, Corymbia terminalis and Ventilago viminalis over a mixed ground layer of tussock and Triodia pungens with occasional shrubs of Senna spp. And Acacia spp. Occurs on low hills on limestones and calcareous shales; calcareous desert soils, some calcareous red-brown earths and skeletal soils. Not a Wetland. (BVG1M: 19b). 1.9.5e: [RE not in use]²: This vegetation community is now mapped as 1.9.11c. Eucalyptus leucophylla low open woodland over a ground layer of tussock grasses. Occurs on stony hills on Tertiary limestones; skeletal soils. Not a Wetland. (BVG1M: 19b). 1.9.5x1: [RE not in use]²: This regional ecosystem is now mapped as 1.9.12. Triodia pungens hummock grassland. Tussock grasses may be present. Emergent Corymbia terminalis and Eucalyptus leucophylla may occur. Occurs on shallow soils overlying limestone. Not a Wetland. (BVG1M: 19b). |

| Fire management guidelines | SEASON: Storm season to early dry season. INTENSITY: Low to moderate. INTERVAL: 4 - 10 years. Ensure some areas are long (10-20 years) unburnt. Adjust intervals/frequency according to rainfall-drought cycles, fuel accumulation and previous fire history. INTERVAL_MIN: 4. INTERVAL_MAX: 20. STRATEGY: Ensure burns are undertaken across the landscape at a range of frequencies to create a mosaic of times since fire. Apply numerous small burns every year to achieve a mosaic and reduce risks of wildfire across vast areas of the landscape. Maintain burnt areas < 20%. ISSUES: Rainfall is a major factor affecting spinifex growth, such that a very wet year or a series of wet years may boost the spinifex fuel load leading to the possibility of extensive wildfire in subsequent years. |
| Comments | 1.9.5b: Almost all trees of Eucalyptus leucophylla multistemmed from the base ie. mallee form. Very extensive community in subregion 2. |
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.
