Protected areas Grey Peaks NP, Daintree NP (CYPAL), Mount Mackay NP, Malbon Thompson FR, Tully Gorge NP, Ngalba-bulal NP (CYPAL), Girringun NP
Special values 7.12.2: Potential habitat for NCA listed species: Gymnostoma australianum.
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 7.12.2: Although freely draining, this regional ecosystem's soils are very wet for much of the year and water tables rarely fall below 2 m. Scattered across the bioregion in areas such as Great Palm Island, May Peak, Mt. Mackay and Thornton Range.
