Fire management guidelines SEASON: Begin burning after the wet season (April-May), but avoid hot, dry season unless a high intensity fire is required to manage thickening, then undertake storm burn. a: Do not burn deliberately. c: Early season burns (April-June). Later burns during storm season will reduce shrub invasion. INTENSITY: Low, with occasional moderate or high intensity to manage thickening and/or stimulate germination. a: Do not burn deliberately. c: Low, with occasional moderate. INTERVAL: 2-5 years. a: Do not burn deliberately. c: 2-3 years. INTERVAL_MIN: 2. INTERVAL_MAX: 5. STRATEGY: Mosaic burn 25-60%. Begin burning early in the fire season, with progressive patch fires burnt through the year. Stop burning when the network of fires and other breaks is sufficient to impede fire spread later in the year. Storm-burning may be used to add further diversity to fire mosaic, promote perennial grasses and arrest woody thickening. a: Maintain appropriate mosaic burning in surrounding country. Do not protect from fire but do not burn deliberately. c: Mosaic burn at a range of frequencies to create mosaic of post-fire responses. ISSUES: In the absence of fire an abundance of rainforest pioneers (e.g., Melastoma spp., Chionanthus ramiflora, Mallotus philippensis, Alyxia spicata and Glochidion spp.) and bracken fern can establish. This development can be rapid (within about 15 years) after which system change is difficult to reverse. Thickening with rainforest species can be detrimental to habitat trees and endangered species (e.g., mahogany glider). Where fire is more common the understorey is usually dominated by tall grasses (e.g., Themeda triandra and Eriachne pallescens), herbaceous plants, lilies and sedges (e.g., Tricoryne anceps, Gonocarpus acanthocarpus, Lomandra longifolia, Dianella caerulea). a: This is mainly a self protecting community. c: Absence of fire can lead to a transition to shrubland. Moderate intensity fire will reduce this change and assist with weeds.
Comments 7.11.34: The Lugger Point area may soon be threatened by development activities. Coastal margin from Cardwell north. 7.11.34d: Patches of bare rock < 0.2 ha are defined as more open areas of the surrounding ecosystems.
