| Short description | Triodia pungens hummock grassland on waning slopes of clayey sandstone and siltstone around margins of Tertiary lateritic surfaces. |
| Structure code | Hummock Grassland |
| Description | Triodia pungens hummock grassland, occasionally with Aristida spp., Schizachyrium fragile and Eriachne spp. Emergent Corymbia grandifolia subsp. grandifolia, Terminalia canescens, Acacia hammondii and Eucalyptus pruinosa subsp. pruinosa may occur. Occurs on sandy outwash deposits overlying sandstone (Floraville Formation), around margins of Tertiary lateritic surfaces. Orange loam soils. Not a Wetland. (BVG1M: 33b). |
| 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. 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. |
