Short description Acacia mangium and A. celsa open forest to closed forest or A. polystachya woodland to closed forest of granite and rhyolite foothills
Structure code Closed Forest
Description Acacia mangium (black wattle) and A. celsa (brown salwood) open forest to closed forest or A. polystachya woodland to closed forest. Granite and rhyolite foothills, of the moist rainfall zone. Not a Wetland. (BVG1M: 5d).

Vegetation communities in this regional ecosystem include:
7.12.12a: Acacia mangium and A. celsa open to closed forest. Lowlands and foothills, of the very wet and wet rainfall zone, on granite and rhyolite. Not a Wetland. (BVG1M: 5d).
7.12.12b: Acacia polystachya dominated communities. Mostly closed forest but includes some woodland with a lower layer of vine forest species. Foothills of the moist rainfall zone, on granite. Not a Wetland. (BVG1M: 5d).
7.12.12c: Acacia polystachya low woodland. Granite and rhyolite. Not a Wetland. (BVG1M: 5d).

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 7.12.12: 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. Mainly the Mount Leach Range, Goolboddi (Orpheus) Island and Macalister Range.
