| Short description | Eucalyptus odontocarpa open shrubland on siliceous metamorphics |
| Structure code | Open Shrubland |
| Description | Eucalyptus odontocarpa open shrubland including occasional Acacia monticola, Acacia retivenea and Grevillea wickhamii. Triodia pungens ground layer. Occurs on siliceous metamorphics on the far west of the Mount Isa Inlier. 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. Shrub diversity may decline over time since fire. |
