Biodiversity status No concern at present
Subregion 4, 6, 2, (5)
Estimated extent1 Pre-clearing 13000 ha; Remnant 2021 13000 ha
Short description Corymbia setosa and/or C. peltata low open woodland on lateritised and deeply weathered surfaces
Structure code Low Open Woodland
Description Low open woodland to open forest of Corymbia setosa (rough-leaved bloodwood) and/or C. peltata (rustyjacket) +/- emergent Eucalyptus crebra (narrow-leaved ironbark) (sens. lat.) +/- Erythrophleum chlorostachys (Cooktown ironwood) +/- Eucalyptus melanophloia (silver-leaved ironbark) +/- E. shirleyi (silver-leaved ironbark) +/- C. lamprophylla +/- Acacia spp. An open to mid-dense shrub layer includes a mixture of juvenile canopy species, Petalostigma banksii (smooth-leaved quinine), Grevillea glauca (bushman's clothes peg), Erythroxylum australe (cocaine tree), Persoonia falcata and Acacia spp. The ground layer is generally grassy and includes Themeda triandra (kangaroo grass), Triodia spp. (spinifex) and Chrysopogon fallax (golden beard grass). Occurs on Tertiary remnant slopes, plateaus and footslopes. Not a Wetland. (BVG1M: 12b).

Fire management guidelines SEASON: Early dry season and storm time. Timing of early dry season burns will vary depending on seasonal conditions; it may sometimes commence as early as March. INTENSITY: Low, with occasional moderate. INTERVAL: 2-5 year intervals with longer unburnt patches. Fuel loads tend to reach a maximum after 2-3 years. Ensure burn programs occur after big wet season as fuel loads will be higher than average. INTERVAL_MIN: 2. INTERVAL_MAX: 5. STRATEGY: Burn less than 40% across the landscape in any year. Burning through the early dry season will produce a network of burns that will contain later fires. Fires will only gain in intensity as the dry season progresses. Grass composition can be affected by timing and intensity of fire. Occasional moderate fire will help to reduce overabundant trees that could potentially suppress ground layer vegetation. ISSUES: Leave areas of long unburnt vegetation to maintain a diversity of habitat for wildlife.
Comments 9.7.5: Occurs in the Greenvale area in the central bioregion. Scalded bare areas are common throughout this unit.
