| Short description | Eucalyptus melanophloia and/or E. shirleyi +/- Corymbia erythrophloia low open woodland on igneous rocks |
| Structure code | Low Open Woodland |
| Description | Low open woodland to woodland of Eucalyptus melanophloia (silver-leaved ironbark) or E. shirleyi (silver-leaved ironbark) +/- Corymbia erythrophloia (red bloodwood) +/- Acacia spp. A sub-canopy of taller shrub-layer species may be present. The shrub layer can be absent to scattered individuals of a wide mixture of species including Petalostigma banksii (smooth-leaved quinine), Terminalia spp., Alphitonia pomaderroides (soapbush), Gardenia vilhelmii (breadfruit), Denhamia cunninghamii (yellowberry bush) and Grevillea glauca (bushman's clothes peg) as well as canopy species. The ground layer is dense grassy and dominated by Schizachyrium spp., and Heteropogon contortus (black speargrass). Occurs on rolling hills and slopes with shallow soils on acid igneous geology, often with boulders to the surface. Not a Wetland. (BVG1M: 13a). |
| Protected areas | Littleton NP, Canyon RR, Bulleringa NP, Littleton RR |
| Special values | 9.12.27: Potential habitat for NCA listed species: Eriocaulon carsonii subsp. orientale, Euphorbia carissoides, Macropteranthes montana, Solanum angustum. |
| 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 | 9.12.27: In small areas in the north Eucalyptus tetrodonta, Erythrophleum chlorostachys and Corymbia erythrophloia may be present. Occurs extensively in the north and west of the bioregion. |
