Protected areas Kroombit Tops NP, Ban Ban NP, Wietalaba NP, Mount Walsh NP, Dawes NP, Mount Blandy CP, Beninbi NP
Special values 12.12.18: Potential habitat for NCA listed species: Scleromitrion gibsonii.
Fire management guidelines INTERVAL: Fire return interval not relevant. INTERVAL_MIN: 100. INTERVAL_MAX: 100. STRATEGY: Do not burn deliberately. Protection relies on broad-scale management of surrounding country. May need active protection from wildfire in extreme conditions or after prolonged drought. Planned burns should not create a running fire into vine forest. Ensuring conditions of good soil moisture and moisture of litter in surrounding communities will limit fire behaviour/intensity. ISSUES: Fire sensitive and not normally flammable. There may be issues with lantana and other weeds from fire and other disturbance. Remnants may be limited by frequent fire at the margins.
Comments 12.12.18: Occurs chiefly in central part of bioregion (e.g. Gayndah). Cleared for pasture and cropping. Remnants require intensive management because of weed invasion and fire damage on margins.

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.
