| Short description | Semi-evergreen vine thicket with Brachychiton australis on Cainozoic igneous rocks, usually in northern half of bioregion |
| Structure code | Closed Forest |
| Description | Low microphyll vine forest and semi-evergreen vine thicket. Characteristic species include Brachychiton australis, Archidendropsis thozetiana, Flindersia australis, F. collina, Psydrax odorata forma buxifolia, Psydrax odorata, Alectryon diversifolius, Acacia fasciculifera, Turraea pubescens, Arytera microphylla, Atalaya salicifolia, Elattostachys xylocarpa, Grevillea helmsiae and Coatesia paniculata. Acacia harpophylla is present on lower slopes and Melaleuca bracteata is often present along watercourses. Occurs on Cainozoic igneous rocks especially basalt and lateritised basalt. Contains Riverine. (BVG1M: 7a). |

| 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 | 12.8.22: Occurs in northern half of bioregion. Characteristic localities for the RE are Coalstoun Lakes National Park and Stony Range near Gin Gin. Extensively cleared for pasture and cropping. Remnants require intensive management because of weed invasion and fire damage on margins. |
