Short description Eucalyptus cullenii, Corymbia hylandii and E. tetrodonta +/- Erythrophleum chlorostachys woodland on metamorphic hills
Structure code Woodland
Description Woodland to low woodland of Eucalyptus cullenii (Cullen's ironbark), Corymbia hylandii (Hyland's bloodwood), E. tetrodonta (Darwin stringybark) +/- Erythrophleum chlorostachys (Cooktown ironwood). There is a sparse to open sub-canopy layer including canopy species, Planchonia careya (cocky apple), and Acacia spp. The very sparse to open shrub layer includes juvenile canopy species, Persoonia falcata (geebung), Grevillea mimosoides (wattle Grevillea), Planchonia careya and Petalostigma spp. (quinine). The ground layer is grassy and includes Sarga plumosum (plume sorghum), Heteropogon contortus (black speargrass), H. triticeus (giant speargrass) and Themeda triandra (kangaroo grass). Occurs on metamorphic ranges and low hills with quartzite. Not a Wetland. (BVG1M: 13a).
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 9.11.12: Occurs near Palmerville in the north-west of the bioregion.
