| Short description | Aristida dominii, Eriachne spp., Chloris lobata +/- Eragrostis basedowii, Iseilema sp. tussock grassland on active Quaternary alluvial plains of major watercourses |
| Structure code | Tussock Grassland |
| Description | Aristida dominii, Eriachne spp. and Chloris lobata annual tussock grassland, commonly with Eragrostis basedowii, Iseilema sp., Themeda arguens and Brachyachne convergens (short grass grassland). Emergent Corymbia confertiflora, Lysiphyllum cunninghamii and Eucalyptus chlorophylla commonly occur. Occurs on active Quaternary alluvial plains, commonly associated with major watercourses. Silty loam soils. Not a Wetland. (BVG1M: 31a). |
| Protected areas | Littleton NP |
| 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. Invasive and high biomass grasses (e.g., buffel, Para and grader grasses) may increase fire severity to the detriment of these ecosystems. |
| Comments | 2.3.41: Subject to degradation from high total grazing pressure and clearing for intensive agriculture. |
