Biodiversity status Of concern
Subregion 2, (1)

Short description Triodia pungens hummock grassland on Cambrian limestones
Structure code Hummock Grassland
Description Triodia pungens hummock grassland. Tussock grasses may be present. Emergent Corymbia terminalis and Eucalyptus leucophylla may occur. Occurs on shallow soils overlying Cambrian limestones. Not a Wetland. (BVG1M: 33b).
Protected areas Boodjamulla (Lawn Hill) NP
Fire management guidelines SEASON: Storm season to early dry season. INTENSITY: Low with occasional moderate. INTERVAL: 4 - 10 years. Ensure patches of long-unburnt vegetation are left (>30 years). Adjust intervals/frequency according to rainfall-drought cycles, fuel accumulation and previous fire history. INTERVAL_MIN: 4. INTERVAL_MAX: 100. STRATEGY: Burning with good soil moisture should ensure a patchy mosaic of burnt and unburnt vegetation should occur. Burn < 20% of the landscape. ISSUES: Seasonal rainfall is a key driver of fuel and therefore fire extent and frequency. Adjust fire regime according to wet season.
Comments 1.9.12: This vegetation community was previously mapped as 1.9.5x1.

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.
