| Short description | Triodia spp. hummock grassland +/- emergent Eucalyptus spp., Melaleuca spp., Corymbia spp. on slopes and crests of lateritised sandstone and mudstone. |
| Structure code | Hummock Grassland |
| Description | Triodia spp. hummock grassland, occasionally with Schizachyrium fragile. Emergent Eucalyptus spp., Melaleuca spp., Corymbia spp. and Acacia meiosperma may occur. Small areas of Eucalyptus spp., Melaleuca citrolens and Corymbia spp. low open woodland or Acacia gonoclada shrubland with Triodia spp. understorey may occur. Occurs on crests, slopes and stripped surfaces of lateritised sandstone and mudstone hills. Not a Wetland. (BVG1M: 33b). Vegetation communities in this regional ecosystem include: 2.7.19a: Triodia spp. hummock grassland, commonly with emergent Eucalyptus melanophloia, Melaleuca citrolens, Corymbia pocillum, M. stenostachya and Acacia meiosperma. Small areas of Eucalyptus melanophloia and/or Melaleuca citrolens low open woodland with Triodia spp. understorey occasionally occur. Occurs on crests and slopes of lateritised, Tertiary sandstone hills. Not a Wetland. (BVG1M: 33b). 2.7.19b: Triodia spp. hummock grassland, occasionally with Schizachyrium fragile. Emergent Melaleuca citrolens, Corymbia pocillum, Eucalyptus cullenii, E. chartaboma and C. serendipita commonly occur. Small areas of M. citrolens, C. pocillum, E. cullenii, E. chartaboma and C. serendipita low open woodland or Acacia gonoclada shrubland may occur. Occurs on slopes and stripped surfaces of lateritised Cretaceous mudstones. Not a Wetland. (BVG1M: 33b). |

| Special values | 2.7.19: Supports plant species with restricted geographic ranges. 2.7.19a: Supports plant species with restricted geographic ranges. |
| 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. |
