| Short description | Petalostigma banksii +/- Gardenia vilhelmii tall shrubland +/-emergent Eucalyptus persistens, Melaleuca citrolens on sandstone hillslopes and colluvial deposits |
| Structure code | Tall Shrubland |
| Description | Petalostigma banksii tall shrubland to open scrub, occasionally with Gardenia vilhelmii. Emergent Corymbia spp. and Melaleuca spp. may occur. A secondary shrub layer of juvenile emergent species and Gardenia vilhelmii commonly occurs. The ground layer is dominated by Schizachyrium sp. Occurs on sandstone hillslopes and colluvial deposits at the base of sandstone scarps. Not a Wetland. (BVG1M: 29b). |

| 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. 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. |
