Regional ecosystem 9.11.32
Vegetation Management Act class Of concern
Wetlands Not a Wetland
Biodiversity status Of concern
Subregion 3, (2), (2.4)
Estimated extent1 Pre-clearing 5000 ha; Remnant 2021 5000 ha
Short description Eucalyptus leptophleba and/or Corymbia terminalis +/- C. dallachiana woodland on aprons surrounding limestone outcrops
Structure code Woodland
Description Woodland to open woodland of Eucalyptus leptophleba (Molloy red box) and/or Corymbia terminalis (western bloodwood) +/- C. dallachiana (Dallachy's gum) +/- E. tetrodonta (Darwin stringybark) +/- C. hylandii (Hyland's bloodwood). The absent to sparse shrub layer can include Planchonia careya (cocky apple) and Capparis spp. The ground layer is grassy and dominated by Heteropogon contortus (black speargrass). Occurs on aprons around limestone karst. Not a Wetland. (BVG1M: 11c).
Protected areas Chillagoe-Mungana Caves 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 9.11.32: Has close ecological links with the semi-evergreen vine thickets of 9.11.8a. This RE may include some areas mapped as geology TQr with soils derived from transported limestone sediments. Occurs around Chillagoe and Palmerville in the north of the bioregion.
