| Short description | Eucalyptus persistens, Corymbia trachyphloia, E. exilipes and C. citriodora in mixed woodlands on exposed ferricrete on Mesozoic sandstone plateau margins. |
| Structure code | Woodland |
| Description | Mixed woodland, including combinations of the species Eucalyptus persistens, Corymbia trachyphloia, E. exilipes and C. citriodora. A shrub layer commonly occurs, including Dodonaea filifolia and Acacia spp. The ground layer is dominated by Cleistochloa subjuncea and Aristida spp. Occurs on exposed ferricrete on Mesozoic sandstone plateau margins. Ferricrete outcrop and skeletal soils. Not a Wetland. (BVG1M: 19d). |
| Special values | 2.7.12: Supports locally uncommon plant species in the bioregion, including Eucalyptus persistens. |
| Fire management guidelines | SEASON: Commence early in dry season as soon as ground fuels can carry fire with fire extinguishing early evening. Continue to mid-dry season. INTENSITY: Low to moderate with occasional high intensity. INTERVAL: 1-5 years, but do not burn the same patches annually. Landscape mosaic should consist of patches with different times since burning. INTERVAL_MIN: 1. INTERVAL_MAX: 5. STRATEGY: Break up continuity of fuel across the landscape so that impact of late-season wildfire is minimised. Wildfire due to dry storms late in the dry season or in the early wet are natural occurrences, but they can burn over a wide area of the landscape with unwanted intensity and frequency. Use broad scale mosaic burning. ISSUES: Overabundant seedlings and saplings can lead to woody thickening if unchecked by fire. A long absence of fire or low intensity fire too early in the season may lead to overabundant seedlings and saplings. If ground fuels are sparse spell pastures prior to planned burns. Weeds such as buffel grass and rubbervine may be an issue for some tussock grass communities because weeds increase fuel loads leading to high intensity fires. |
