Regional ecosystem details for 9.12.21

Regional ecosystem 9.12.21
Vegetation Management Act class Of concern
Wetlands Not a Wetland
Biodiversity status Of concern
Subregion 4, (7.5)
Estimated extent1 Pre-clearing 10000 ha; Remnant 2021 10000 ha
Short description Eucalyptus crebra or E. drepanophylla and Corymbia spp. open woodland on flat to undulating country on igneous rocks
Structure code Open Woodland
Description Open woodland to woodland of Eucalyptus crebra (narrow-leaved ironbark) or E. drepanophylla (grey ironbark) and Corymbia clarksoniana (Clarkson's bloodwood) or C. erythrophloia (red bloodwood) +/- C. dallachiana (Dallachy's gum) +/- Eucalyptus platyphylla (poplar gum). An open sub-canopy of canopy species can occur. The shrub layer is absent to scattered Melaleuca viridiflora (broad-leaved paperbark), Bursaria incana (prickly pine) and Vachellia bidwillii (corkwood wattle). The often grassy ground layer is dominated by Heteropogon contortus (black speargrass) and Themeda triandra (kangaroo grass). Occurs on flat to undulating country on igneous geology. Not a Wetland. (BVG1M: 13c).
Protected areas Paluma Range NP
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 9.12.21: Is distinguished from RE 9.12.22 and RE 9.12.2 by the different mix of dominant species and by a different landform. Occurs near Harvey Range in the south of the bioregion. Subject to minor clearing.
