| Regional ecosystem | 9.12.10 |
|---|---|
| Vegetation Management Act class | Of concern |
| Wetlands | Not a Wetland |
| Biodiversity status | Of concern |
| Subregion | 2, 4, (5) |
| Estimated extent1 | Pre-clearing 7000 ha; Remnant 2021 7000 ha |
| Short description | Corymbia confertiflora and Eucalyptus crebra +/- C. clarksoniana open woodland on rolling igneous hills |
| Structure code | Open Woodland |
| Description | Open woodland to woodland of Corymbia confertiflora (broad-leaved carbeen) and Eucalyptus crebra (narrow-leaved ironbark) +/- C. erythrophloia (red bloodwood) or C. clarksoniana (Clarkson's bloodwood) +/- E. microneura (Georgetown box). Isolated canopy species can occur in the sub-canopy. The shrub layer is absent to very sparse and can contain juvenile canopy species, Grevillea striata (beefwood), Atalaya hemiglauca (whitewood) and Carissa lanceolata (currantbush). The ground layer varies from mid-dense to dense and is dominated by Heteropogon contortus (black speargrass) and Aristida spp. (three-awned grasses). Occurs on rolling igneous hills. Not a Wetland. (BVG1M: 13c). |
| 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 | 9.12.10: Occurs west of the Lynd Junction in the central bioregion. |
