| Short description | Aristida latifolia +/- Enneapogon polyphyllus, Brachyachne convergens, Sporobolus spp. tussock grassland on thin, residual sand deposits overlying Tertiary clay plains |
| Structure code | Open Tussock Grassland |
| Description | Aristida latifolia tussock grassland to open tussock grassland, commonly with Enneapogon polyphyllus, Brachyachne convergens and Sporobolus spp. Occurs on thin, gravelly Quaternary residual sand deposits, commonly overlying Tertiary clay plains. Pale brown sandy loams (commonly with surface gravel). Not a Wetland. (BVG1M: 31a). Vegetation communities in this regional ecosystem include: 2.5.35x1: [RE not in use]²: This regional ecosystem is now mapped as 2.5.43. Eriachne spp. and Aristida latifolia tussock grassland to closed tussock grassland, commonly with Chrysopogon fallax. Contains small wetlands, including Pseudoraphis spinescens and Oryza australiensis. Occurs on outwash deposits of eroded lateritic material. Texture contrast soils with orange to brown loams and clays loams at the surface and brown clays in the base of the wetlands. Contains Palustrine. (BVG1M: 32a). |
| Fire management guidelines | SEASON: March to April, with occasional storm burns if woody weeds are a problem. INTENSITY: Low, occasionally moderate and high intensities. INTERVAL: 3-6 years south of latitudes below Karumba, 1-3 years to the north. INTERVAL_MIN: 1. INTERVAL_MAX: 6. STRATEGY: Commence burning early in dry season to break up continuity of fuel across the landscape. Mosaic burning across the landscape at varying frequency will create patches at varying stages of post-fire response. Burn with good soil moisture to promote regeneration. ISSUES: Retaining grasslands by preventing woody thickening may be an issue in some situations. A long absence of fire or low intensity fire too early in the season may lead to overabundant seedlings and saplings. Vachellia spp. are tolerant of fire once past the seedling stage. |
| Comments | 2.5.35: Was previously mapped as 2.5.2x5. May be invaded by exotic Vachellia spp. |
1 Estimated extent is from version 13.1 pre-clearing and 2021 remnant regional ecosystem mapping. Figures are rounded for simplicity. For more precise estimates, including breakdowns by tenure and other themes see remnant vegetation in Queensland.
2 Superseded: Revision of the regional ecosystem classification removed this regional ecosystem code from use. It is included in the regional ecosystem description database because the RE code may appear in older versions of RE mapping and the Vegetation Management regulation.
