| Short description | Acacia polystachya woodland to closed forest, or Acacia mangium and Acacia celsa open forest to closed forest, on metamorphics |
| Structure code | Closed Forest |
| Description | Acacia polystachya woodland to closed forest, or Acacia mangium (black wattle) and Acacia celsa (brown salwood) open forest to closed forest. Metamorphics. Not a Wetland. (BVG1M: 5d). Vegetation communities in this regional ecosystem include: 7.11.8a: Acacia polystachya dominated communities. Mostly closed forest but includes some woodlands with a lower layer of vine forest species. Foothills on metamorphics of the moist rainfall zone. Not a Wetland. (BVG1M: 5d). 7.11.8b: Acacia mangium and A. celsa open forest to closed forest. Lowlands and foothills on metamorphics, of the very wet and wet rainfall zone. Not a Wetland. (BVG1M: 5d). 7.11.8c: Acacia polystachya low woodland. Metamorphic foothills. Not a Wetland. (BVG1M: 5d). |

| Protected areas | Daintree NP (CYPAL), Ngalba-bulal NP (CYPAL), Macalister Range NP, Mowbray NP, Annan River (Yuku Baja-Muliku) NP, Eubenangee Swamp NP, Little Mulgrave NP, Kuranda West FR |
| 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 | 7.11.8: These communities occur in areas of natural disturbance, probably derived from sclerophyll communities. Some appear to be quite stable (long term), whilst some areas are the effects of more recent (natural) disturbance. Central and northern parts of the bioregion (north of about Innisfail). This widespread regional ecosystem is a result of past disturbances, particularly cyclones and/or past logging, and is a long-lasting intermediate successional regional ecosystem, which in places could be considered a deflected successional system. |
