| Short description | Corymbia polycarpa and/or C. bella +/- Lysiphyllum cunninghamii, C. curtipes woodland on abandoned levees on Tertiary clay plains |
| Structure code | Woodland |
| Description | Corymbia polycarpa and/or C. bella woodland, commonly with Lysiphyllum cunninghamii and C. curtipes. Atalaya hemiglauca, Grevillea striata and Terminalia platyphylla may occur in the canopy. The ground layer is tussock grasses, including Heteropogon contortus and Eriachne spp. Occurs on abandoned levees and sand ridges associated with Tertiary clay plains (Wondoola Plains subregion). Pale brown sandy loam soils. Not a Wetland. (BVG1M: 16b). |
| 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. |
