| Short description | Acacia torulosa, Corymbia setosa and A. platycarpa in mixed tall shrublands on degraded residuals of inland sand dunes |
| Structure code | Tall Shrubland |
| Description | Mixed tall shrubland to low open woodland (dependent on fire frequency), including combinations of the species Acacia torulosa, Corymbia setosa and Acacia platycarpa. Emergent C. grandifolia may occur. A narrow fringe of Melaleuca spp. and C. polycarpa low woodland commonly occurs around the margins. The ground layer is sparse tussock grasses including Aristida holathera and Eriachne obtusa with areas of bare soil. Occurs on sandy plains with elongated striations (degraded residuals of inland sand dunes). Deep red-brown sand. Not a Wetland. (BVG1M: 18a). |
| 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. Fire-killed acacias produce seed at 5 years, so some longer unburnt patches need to be retained. 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. |
