| Short description | Eucalyptus pruinosa low open woodland on older alluvial and residual soils |
| Structure code | Low Open Woodland |
| Description | Eucalyptus pruinosa low open woodland often with Corymbia terminalis, E. leucophylla, Acacia cambagei or Grevillea striata and with a sparse mixed shrub layer and dense tussock grass ground layer dominated by Aristida spp. with Triodia spp. often present. Occurs on older alluvial and residual soils. Not a Wetland. (BVG1M: 19c). |
| Protected areas | Lawn Hill (Arthur Creek) RR, Wiliyan-ngurru NP, Boodjamulla (Lawn Hill) NP, Lawn Hill (Widdallion) RR, Lawn Hill (Gregory) RR, Lawn Hill (Stockyard Creek) RR, Lawn Hill (Lilydale) RR |
| 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. |
