| Structure code | Closed Vineland |
| Description | Closed vineland of wind-disturbed vine forest. Granites and rhyolites. Not a Wetland. (BVG1M: 5d). Vegetation communities in this regional ecosystem include: 7.12.40a: Open areas in vine forests, dominated by sprawling vines, commonly Decalobanthus peltatus and a number of other vine species, presumed to mostly originate from cyclone damaged Type 2a forests (where the entire canopy has been destroyed.). Generally foothills of coastal ranges below 400 metres. Not a Wetland. (BVG1M: 5d). 7.12.40b: Mesophyll to notophyll vine forest suffering from extreme wind damage where at least half the canopy has been destroyed. Granite and rhyolite. Not a Wetland. (BVG1M: 5d). 7.12.40c: Complex notophyll vine forest (with emergent Agathis robusta) suffering from extreme wind damage where at least half the canopy has been destroyed. Granite and rhyolite. Not a Wetland. (BVG1M: 5d). 7.12.40d: Simple notophyll vine forest (often with Agathis microstachya) suffering from extreme wind damage where at least half the canopy has been destroyed. Granite. Not a Wetland. (BVG1M: 5d). 7.12.40e: Complex mesophyll vine forest suffering from extreme wind damage where at least half the canopy has been destroyed. Colluvium of the very wet and wet rainfall zones. Not a Wetland. (BVG1M: 5d). |

| Special values | 7.12.40: Potential habitat for NCA listed species: Aphyllorchis anomala, Arenga australasica, Diplazium cordifolium, Endiandra anthropophagorum, Endiandra bellendenkerana, Microsorum membranifolium, Piper mestonii. |
| Fire management guidelines | INTERVAL: Fire return interval not relevant. INTERVAL_MIN: 100. INTERVAL_MAX: 100. STRATEGY: Do not burn deliberately. Mosaic burning in surrounding fire-adapted ecosystems will minimise spread and severity of wildfire during severe weather events. ISSUES: Occasional hot fires in adjoining communities may be required to prevent expansion of rainforest elements. Edges are generally self-protecting but back burning from rainforest edges may be desirable. The occurrence of high biomass grasses in or adjacent to rainforest may detrimentally affect rainforest during fire events associated with dry weather. |
| Comments | 7.12.40: Naturally wind or cyclone-disturbed communities that appear to be in a stable state either due to repeated disturbance and exposure, or due to the perpetual prevention of tree regeneration under the vine tangle. Scattered across the bioregion, especially common on the Bellenden Ker Range. |
