Regional ecosystem 9.12.26
Vegetation Management Act class Of concern
Wetlands Not a Wetland
Biodiversity status Of concern
Subregion 4, 6, (7.5), (7.6)
Estimated extent1 Pre-clearing 3000 ha; Remnant 2021 3000 ha
Short description Eucalyptus moluccana +/- E. crebra and/or E. granitica woodland on igneous rocks
Structure code Woodland
Description Woodland to open forest of Eucalyptus moluccana (gum-topped box) +/- E. crebra (narrow-leaved ironbark) and/or E. granitica (granite ironbark) +/- Corymbia dallachiana (Dallachy's gum). A very open sub-canopy of canopy species can occur. There is no shrub layer and the dense grassy ground layer is dominated by Themeda triandra (kangaroo grass) and Heteropogon contortus (black speargrass) with Cyperus spp. (sedges) often present. Occurs on lower slopes and valleys of a low hilly landscape. Not a Wetland. (BVG1M: 13d).
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 9.12.26: Occurs in small areas close to the boundary of the Wet Tropics bioregion in the south of the bioregion. Subject to minor clearing and vulnerable to invasion by the weed species Lantana camara.
