| Short description | Eucalyptus leucophloia low open woodland to woodland on sandy and gravelly red soils |
| Structure code | Low Open Woodland |
| Description | Eucalyptus leucophloia low open woodland to woodland sometimes with shrubby understorey dominated by Acacia spp. Usually Triodia spp. dominated ground cover. Includes areas of Corymbia terminalis woodland. Occurs on undulating plateau surfaces, valley infill and outwash plains. Not a Wetland. (BVG1M: 19a). |

| 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 | 1.5.3: Widespread throughout the bioregion. |
