| Short description | Semi-evergreen vine thicket with Brachychiton rupestris on Cainozoic igneous rocks, usually in southern half of bioregion |
| Structure code | Closed Forest |
| Description | Low microphyll vine forest and semi-evergreen vine thicket +/- Araucaria cunninghamii. 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 Cainozoic igneous rocks, especially basalt. Contains Riverine. (BVG1M: 7a). |

| Protected areas | Bunya Mountains NP, Woroon NP, Nangur NP, Dwyers Scrub CP, Boat Mountain CP 2, Boat Mountain CP 1, Main Range CP, Flagstone Creek CP |
| Special values | 12.8.21: Habitat for near threatened plant species including Callitris baileyi and Cryptocarya floydii. |
| 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 | 12.8.21: Confined to south of bioregion. Lockyer Valley and Bunya Mountains. Remnants require intensive management because of invasion by weeds and fire damage on margins. |
