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.
