| Short description | Eucalyptus leucophylla and/or Corymbia terminalis +/- C. aparrerinja low open woodland on igneous rocks |
| Structure code | Low Open Woodland |
| Description | Eucalyptus leucophylla low open woodland often with Corymbia terminalis or C. aparrerinja, shrub layer of Acacia chisholmii with hummock grass ground layer of Triodia spp. Includes areas of treeless Triodia spp. grasslands and Acacia spp. shrublands. Occurs on ranges and stony hills and rises on igneous rocks; skeletal soils and some shallow red earths. Not a Wetland. (BVG1M: 19b). Vegetation communities in this regional ecosystem include: 1.12.3a: Eucalyptus leucophylla low open woodland often with Corymbia terminalis or C. aparrerinja, shrub layer of Acacia chisholmii with hummock grass ground layer of Triodia spp. Includes areas of treeless Triodia spp. grasslands and Acacia spp. shrublands. Occurs on ranges and stony hills and rises on igneous rocks; skeletal soils and some shallow red earths. Not a Wetland. (BVG1M: 19b). 1.12.3b: Mixed low open woodland including Eucalyptus leucophylla, Atalaya hemiglauca, Corymbia terminalis, C. aparrerinja, Acacia cambagei, Grevillea striata, Hakea spp. and Acacia excelsa subsp. angusta and a sparse ground layer of short tussock grasses and Triodia spp. Occurs on near level plains to undulating rises. Not a Wetland. (BVG1M: 19b). 1.12.3c: Corymbia terminalis and/or Eucalyptus leucophylla low open woodland, sometimes with Corymbia aparrerinja, Eucalyptus leucophloia, Atalaya hemiglauca and/or Psydrax attenuata. Acacia chisholmii generally dominates the shrub layer. Triodia spp. dominated ground layer. Occurs on dolerite and basalts. 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. b: Sparse ground layer will inhibit the ability to burn. |
| Comments | 1.12.3b: These are usually extremely open communities with very sparse ground layers. |
