Short description Eucalyptus pruinosa low open woodland on shale hills
Structure code Low Open Woodland
Description Eucalyptus pruinosa low open woodland. Sparse shrub layer of Acacia spp. Triodia pungens ground layer. Occurs on hills on pre-Cambrian shales; skeletal soils, some shallow loams. Not a Wetland. (BVG1M: 19c).

Vegetation communities in this regional ecosystem include:
1.9.7a: [RE not in use]²: This vegetation community is now mapped as 1.9.13. Eucalyptus leucophloia low open woodland with a variable shrub layer of Acacia spp., often Acacia hilliana or Acacia phlebocarpa, over ground cover of Triodia pungens. Occurs on hills on pre-Cambrian shales; skeletal soils, some shallow loams. Not a Wetland. (BVG1M: 19a).
1.9.7b: [RE not in use]²: This vegetation community is now mapped as 1.9.14. Eucalyptus pruinosa low open woodland. Sparse shrub layer of Acacia spp. Triodia pungens ground layer. Occurs on hills on pre-Cambrian shales; skeletal soils, some shallow loams. Not a Wetland. (BVG1M: 19c).
1.9.7c: [RE not in use]²: This vegetation community is now mapped as 1.9.7. Corymbia terminalis woodland often with Eucalyptus leucophloia or Eucalyptus pruinosa. Occurs on hills on pre-Cambrian sediments in the north of the bioregion. 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.

1 Estimated extent is from version 13.1 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2 Superseded: Revision of the regional ecosystem classification removed this regional ecosystem code from use.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.
