Short description Panicum trachyrhachis closed tussock grassland in shallow depressions on old alluvial plains (recent Pleistocene surface)
Structure code Tussock Grassland
Description Panicum trachyrhachis closed tussock grassland. Occurs in shallow depressions on silty, old alluvial plains (recent Pleistocene surface) in the Doomadgee Plains subregion. 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. Invasive and high biomass grasses (e.g., buffel, Para and grader grasses) may increase fire severity to the detriment of these ecosystems.
Comments 2.3.57: A poorly surveyed vegetation community. Was previously mapped as 2.3.20x1e. Potentially subject to feral pig damage.
