| Short description | Corymbia terminalis low open woodland on sandy red earth plains |
| Structure code | Low Open Woodland |
| Description | Corymbia terminalis low open woodland on sandy red soils. Associated species include Grevillea striata, Acacia excelsa, Corymbia aparrerinja, Acacia aneura, Atalaya hemiglauca and Hakea lorea subsp. lorea. Ground layer dominated by Triodia pungens. Occurs on Tertiary and Quaternary outwash sandplains, in places reworked by wind; deep loamy red earths. Not a Wetland. (BVG1M: 19b). |
| Protected areas | Wiliyan-ngurru NP |
| 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. |
