| Short description | Eucalyptus microtheca woodland on level plains derived from deeply weathered siltstones |
| Structure code | Woodland |
| Description | Eucalyptus microtheca low woodland to woodland. A sparse secondary tree layer commonly occurs, including Grevillea striata, Atalaya hemiglauca and Melaleuca viridiflora. The ground layer is tussock grasses including Dichanthium spp., Aristida latifolia, Eulalia aurea and Chrysopogon fallax. Occurs on level plains derived from deeply weathered siltstones (Donors Plateau subregion). Yellow to brown clays. Not a Wetland. (BVG1M: 18c). |
| 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. |
| Comments | 2.5.32: Was previously mapped as 2.5.12x7. Likely to be a groundwater dependent ecosystem. |
