Fire management guidelines SEASON: Oct-Dec (occasionally Sep). a, b, d: Early to mid-dry season in normal season (March-May). Early to late-season in wet year (March-Sep). e, f: Do not burn deliberately. INTENSITY: Variable, depending on fuel. a, b, d: Low to moderate. e, f: Do not burn deliberately. INTERVAL: 10-20 years. There will be practical difficulties in attempting to burn grassland and sedgeland at different intervals. a, b, d: 3-10 years. e, f: Do not burn deliberately. INTERVAL_MIN: 3. INTERVAL_MAX: 100. STRATEGY: Entire continuous areas are likely to burn at any one time. Burn 25-30% of these communities in WET in any one year. Attempt to time burning when water level is high enough to cover both peat and sedge bases. Protect from wildfire or manage surrounding country to reduce the potential of fire incursion. a, b, d: Patch burn (<30% of area) early in the dry season to limit the extent and intensity of wildfires. Fires may, depending on the conditions and type of vegetation, burn areas larger than just the melaleuca ecosystem. Ensure secure boundaries from non fire-regime adapted ecosystems. Use topography to restrict spread of fire. Consider the needs of melaleuca ecosystems based on understorey (i.e., heath dominated, sedge dominated or mixed grass/shrub) when planning burns. High soil moisture (or presence of water on the ground) is required, as avoidance of peat-type fires must be maintained. e, f: Do not burn deliberately. Mosaic burning in surrounding fire-adapted ecosystems will minimise spread and severity of wildfire during severe weather events. ISSUES: A planned burn is likely to be over 100% of the planned burn area; so while mosaic burning is desirable to maintain structure and protect animal habitat and food, it will rarely be achievable. Under dry conditions, with little soil moisture, peat may burn as it is highly flammable in such circumstances. Sedges are disadvantaged by repeated high intensity fires. a, b, d: Restrict extent and intensity of fires. High intensity and extensive fires degrade vegetation structure and destroy animal habitats. Melaleuca forests are fire-adapted, but too high an intensity or frequent fire will slow or prevent regeneration and lead to lower species richness (since these communities contain numerous obligate seed regenerating species that require sufficient fire intervals to produce seed). High intensity fires may kill trees and lead to whipstick regeneration. Too frequent fire may result in a net loss of nutrients over time from an already nutrient poor system. Fire associations are significantly influenced by understorey composition. e, f: 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 7.11.40: Western edge of Thornton Range, north of the Daintree River. 7.11.40i: Patches of bare rock < 0.2 ha are defined as more open areas of the surrounding ecosystems.
