Vegetation Management Act class Of concern
Biodiversity status Endangered
Subregion 3
Estimated extent1 Pre-clearing 400 ha; Remnant 2017 400 ha
Extent in reserves No representation
Short description Mixed tussock grassland on basic igneous rocks
Structure category Grassland
Description Mixed tussock grassland including Eulalia aurea, Iseilema spp., Brachyachne convergens, Bothriochloa ewartiana, Aristida latifolia, Dichanthium spp. and Themeda triandra with emergent trees including Corymbia terminalis, Eucalyptus pruinosa and Eucalyptus leucophylla often with Triodia longiceps, associated with outcropping rocks. Occurs on basic igneous rocks. (BVG1M: 30b)
Fire management guidelines SEASON: Storm season to very early dry season. INTENSITY: Low with occasional moderate. INTERVAL: 10 - 30 years. Adjust intervals/frequency according to rainfall-drought cycles, fuel accumulation and previous fire history. STRATEGY: Burn in association with surrounding country. Maintain mosaic burning in surrounding country to mitigate against spread of unplanned fire. ISSUES: Seasonal rainfall is a key driver of fuel and therefore fire extent and frequency. Adjust fire regime according to wet season. Too frequent fire can promote annual grasses over perennial.
