| Short description | Corymbia aparrerinja open woodland on sandy red earths |
| Structure code | Open Woodland |
| Description | Corymbia aparrerinja open woodland often with Grevillea striata, Corymbia terminalis and Eucalyptus leucophylla. Sparse mixed shrub layer and ground layer of Triodia pungens and tussock grasses. Occurs on sandy red earths. Not a Wetland. (BVG1M: 19b). Vegetation communities in this regional ecosystem include: 1.5.14a: Corymbia aparrerinja open woodland, often with Corymbia terminalis. A second tree layer of Eucalyptus pruinosa is usually present with a mixed shrub layer and ground layer of tussock grasses and Triodia pungens. Occurs on shallow residual Tertiary surfaces overlying limestones. Not a Wetland. (BVG1M: 19b). 1.5.14b: Corymbia aparrerinja open woodland often with Grevillea striata, Corymbia terminalis and Eucalyptus leucophylla. Sparse mixed shrub layer and ground layer of Triodia pungens and tussock grasses. Occurs on sandy red earths. Not a Wetland. (BVG1M: 19b). |

| Fire management guidelines | SEASON: Storm season to very early dry season. INTENSITY: Low with occasional 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. Fuel loads tend to be higher where there is a mix of tussock and spinifex grasses. |
