| Description | Low microphyll vine forest +/- Araucaria cunninghamii and semi-evergreen vine thicket. Characteristic species include Brachychiton australis, B. rupestris, Archidendropsis thozetiana, Flindersia australis, F. collina, Psydrax odorata forma buxifolia, Alectryon diversifolius, Acacia fasciculifera, Turraea pubescens, Arytera microphylla, Atalaya salicifolia, Elattostachys xylocarpa, Grevillea helmsiae and Coatesia paniculata. Melaleuca bracteata is often present along watercourses. Occurs on Mesozoic to Proterozoic igneous rocks. Contains Palustrine. (BVG1M: 7a). |

| Protected areas | Kroombit Tops NP, Ban Ban NP, Wietalaba NP, Mount Walsh NP, Dawes NP, Mount Blandy CP, Beninbi NP |
| Special values | 12.12.18: Potential habitat for NCA listed species: Scleromitrion gibsonii. |
| 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 | 12.12.18: Occurs chiefly in central part of bioregion (e.g. Gayndah). Cleared for pasture and cropping. Remnants require intensive management because of weed invasion and fire damage on margins. |
