Short description Eucalypt woodland and deciduous woodland on hills on granitic rocks
Structure category Sparse
Description Eucalyptus spp. and Corymbia spp. woodlands, and deciduous low woodlands. Occurs on hills on acid igneous or acid volcanic rocks; skeletal soils. (BVG1M: 13a)

Vegetation communities in this regional ecosystem include:
2.12.1a: Eucalyptus crebra or E. cullenii woodland, commonly with Erythrophleum chlorostachys, Corymbia erythrophloia and C. hylandii in the canopy. A shrub layer may occur, including Petalostigma banksii, Erythrophleum chlorostachys and Gardenia vilhelmii. The ground layer is commonly tussock grasses. Occurs on granite slopes and gullies, commonly underlying sandstones. (BVG1M: 13a)
2.12.1b: Mixed low woodland, including combinations of the species Melaleuca citrolens, Acacia leptostachya, Eucalyptus microneura, M. viridiflora, M. stenostachya and A. julifera subsp. gilbertensis. Corymbia pocillum, Petalostigma spp. and Alphitonia sp. may occur in the canopy. Patches of M. foliolosa can occur on areas of skeletal soil close to bases of ridgelines. The ground layer is commonly tussock grasses. Occurs on granite slopes and gullies, commonly underlying sandstones. (BVG1M: 13a)

Fire management guidelines SEASON: Commence burning 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. 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 2.12.1: Includes a number of regional ecosystems that are all outliers of adjacent bioregions.
