| Short description | Eucalyptus melanophloia, Acacia julifera subsp. gilbertensis, Corymbia setosa and Melaleuca spp. in mixed low woodlands on Tertiary sand sheets |
| Structure code | Low Woodland |
| Description | Mixed low woodland to woodland, including combinations of the species Eucalyptus melanophloia, Acacia julifera subsp. gilbertensis, Corymbia setosa, Melaleuca spp., E. microneura and Erythrophleum chlorostachys. A variable shrub layer commonly occurs, including canopy species, Acacia spp. and Petalostigma banksii. The ground layer is tussock grasses, including Thaumastochloa spp., Schizachyrium fragile and Chrysopogon sp. Occurs on undulating, erosional, Tertiary sand sheets. Yellow to brown sands and loams. Not a Wetland. (BVG1M: 17b). |

| 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. |
