| Description | Low microphyll vine forest +/- Araucaria cunninghamii and semi-evergreen vine thicket. Characteristic species include Brachychiton rupestris, Flindersia collina, F. australis, Alectryon diversifolius, A. subdentatus, Elattostachys xylocarpa, Erythroxylum sp. (Splityard Creek L.Pedley 5360), Psydrax odorata forma buxifolia, Diospyros geminata, Planchonella cotinifolia, Croton insularis, Bridelia exaltata and Bursaria incana. Melaleuca bracteata is often present along watercourses. Occurs on Mesozoic to Proterozoic igneous rocks. Contains Palustrine. (BVG1M: 7a). |

| Protected areas | Oakview NP, Nangur NP, Kroombit Tops NP |
| Fire management guidelines | INTERVAL: Fire return interval not relevant. INTERVAL_MIN: 100. INTERVAL_MAX: 100. STRATEGY: Do not burn deliberately. Protection relies on broad-scale management of surrounding country. May need active protection from wildfire in extreme conditions or after prolonged drought. Planned burns should not create a running fire into vine forest. Ensuring conditions of good soil moisture and moisture of litter in surrounding communities will limit fire behaviour/intensity. ISSUES: Fire sensitive and not normally flammable. There may be issues with lantana and other weeds from fire and other disturbance. Remnants may be limited by frequent fire at the margins. |
| Comments | 12.12.17: Occurs in south of bioregion and extends into adjacent parts of the brigalow belt. Characteristic localities include Nangur and Mount Beppo. Cleared for pasture and cropping. Remnants require intensive management because of invasion by weeds and fire damage on margins. |
