| 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 | 7.11.3: The dense even canopy (18-32 m tall) is composed of a mixture of deciduous and evergreen trees. Deciduous emergent trees are widely spaced. Emergent trees commonly possess very large plank buttresses up to 5 m in height. Surface roots are common. Footslopes from Cairns north. Subject to reduction by fire in many parts of its range. |
