| Regional ecosystem | 11.5.6 |
|---|---|
| Vegetation Management Act class | Of concern |
| Wetlands | Not a Wetland |
| Biodiversity status | Of concern |
| Subregion | 34, (33) |
| Estimated extent1 | Pre-clearing 3000 ha; Remnant 2021 3000 ha |
| Short description | Triodia spp. hummock grassland on Cainozoic sand plains and/or remnant surfaces |
| Structure code | Hummock Grassland |
| Description | Triodia spp. hummock grassland +/- shrubs and scattered low trees. Eucalyptus melanophloia is a common emergent tree, along with occasional Corymbia clarksoniana or C. terminalis. A shrub layer commonly occurs, its density and composition highly variable and affected by the frequency of fires. Scattered tussock grasses and seasonally prominent forbs occur between the hummock grass layer. Occurs on Cainozoic sandplains. Not a Wetland. (BVG1M: 33b). |
| Supplementary description | Isbell (1957), MU12; Neldner (1984), 65 (147) |
| Fire management guidelines | SEASON: Late wet to early dry season when there is good soil moisture. Early storm season or after good spring rains. INTENSITY: Moderate to high. INTERVAL: 4 - 10 years. Ensure some areas are long (10-20 years) unburnt. INTERVAL_MIN: 4. INTERVAL_MAX: 20. STRATEGY: Burn less than 30% annually to maintain a mosaic. ISSUES: Burning of spinifex may help control encroachment by cypress. |
| Comments | 11.5.6: Can be floristically diverse but requires appropriate burning to maintain species composition. |
