| Structure code | Closed Forest |
| Description | Semi-deciduous mesophyll vine forest. Lowlands and foothills on granites and rhyolites, of the moist and dry rainfall zones. Not a Wetland. (BVG1M: 2d). Vegetation communities in this regional ecosystem include: 7.12.6a: Semi-deciduous mesophyll vine forest. Lowlands and foothills of the moist and dry rainfall zones, on granite and rhyolite. Not a Wetland. (BVG1M: 2d). 7.12.6b: Terminalia arenicola and Acacia polystachya low closed forest. Lowlands and foothills, of the moist and dry rainfall zones, on rhyolite. Not a Wetland. (BVG1M: 7a). |
| Supplementary description | Stanton and Stanton (2005), R4, G4, R172; Tracey and Webb (1975), 4 |
| Protected areas | Ngalba-bulal NP (CYPAL), Annan River (Yuku Baja-Muliku) NP, Kalkajaka NP (CYPAL) |
| Special values | 7.12.6: Potential habitat for NCA listed species: Dendrobium bigibbum, Rhaphidospora cavernarum. |
| 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 | 7.12.6: Deciduous emergents to 35 m and trees with plank buttressing and surface roots are common. Most of the larger leaf species are deciduous. This regional ecosystem has close affinities with regional ecosystems more common in the Cape York Peninsula bioregion. Only present in Daintree - Bloomfield sub-region, mainly on the Black Trevethan Range. This regional ecosystem tends to be highly susceptible to woody weed invasion, including African tulip tree (Spathodea campanulata) and mango (Mangifera indica). |
