Regional ecosystem details for 2.7.7
| Regional ecosystem | 2.7.7 |
|---|---|
| Vegetation Management Act class | Least concern |
| Wetlands | Not a Wetland |

| Subregion | 8, (2) |

| Short description | Corymbia aparrerinja and/or Corymbia grandifolia subsp. grandifolia +/- Cochlospermum gregorii open woodland on Tertiary lateritic plateau surfaces |
| Structure code | Open Woodland |
| Description | Corymbia aparrerinja and/or Corymbia grandifolia subsp. grandifolia open woodland, occasionally with Cochlospermum gregorii. A secondary tree layer may occur, including Eucalyptus leucophloia, Eucalyptus pruinosa subsp. pruinosa and Terminalia canescens. A sparse shrub layer may occur, including Acacia lysiphloia and A. hammondii. The ground layer is dominated by Triodia pungens. Occurs on surfaces of Tertiary lateritic plateaus. Brown skeletal sandy soils over ferricrete. Not a Wetland. (BVG1M: 19a). |
| Fire management guidelines | SEASON: Burn in the wet season or very soon after. INTENSITY: Low to moderate, although spinifex will naturally burn with high intensity in some areas. INTERVAL: 2-7 years. Fire-killed acacias produce seed at 5 years, so some longer unburnt patches need to be retained. INTERVAL_MIN: 2. INTERVAL_MAX: 7. STRATEGY: Apply fire at sufficient intervals such that hummocks do not form a continuous fuel layer across the landscape. Use broad scale mosaic burning. Burn when the soil is moist as it promotes post-fire recovery of spinifex. ISSUES: Spinifex is highly flammable. Green spinifex will also burn readily. |
