| Short description | Eucalyptus crebra and Corymbia citriodora subsp. citriodora +/- Corymbia spp. woodland on metamorphic hills and mountains in far south-west of bioregion |
| Structure code | Woodland |
| Description | Woodland to open forest of Eucalyptus crebra (narrow-leaved ironbark) and Corymbia citriodora subsp. citriodora (lemon-scented gum) +/- Corymbia spp. A sparse to mid-dense sub-canopy can occur and include canopy species as well as Grevillea spp., Bursaria incana (prickly pine) and Acacia burdekensis (Burdekin wattle). The shrub layer can be absent to dense and include Denhamia cunninghamii (yellowberry bush), juvenile canopy species, A. burdekensis and Jacksonia ramosissima (angled broom bush). The mid-dense to dense grassy ground layer is dominated by a combination of Heteropogon contortus (black speargrass), Sarga plumosum (plume sorghum), H. triticeus (giant speargrass) and Themeda triandra (kangaroo grass). Occurs on undulating hills and some isolated 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 | 9.11.14: Occurs in areas which are wetter due to their higher altitude (700m to 900m ASL) in the south west of the bioregion. |
