| Fire management guidelines | SEASON: Do not target for deliberate burning. c: 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. INTENSITY: Do not target for deliberate burning. c: Low, with occasional moderate or high intensity to manage thickening and/or stimulate germination. INTERVAL: Do not target for deliberate burning. c: 2-5 years. INTERVAL_MIN: 2. INTERVAL_MAX: 5. STRATEGY: Limit fire encroachment from adjacent ecosystems by burning when conditions are favourable. Burn away from edges. c: 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. ISSUES: Typically unlikely to burn owing to lack of flammable grasses. Occasional high intensity fires along fringes, particularly on hillslopes, may lead to loss of rainforest at edges. Low intensity burns away from rainforest edge can be used to protect margins, when humidity and soil moisture are high. Where appropriate, use revegetation of rainforest species to provide buffer to cleared areas. Occasional high intensity fires in adjoining communities may be required to prevent expansion of rainforest elements. c: 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. 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). |
| Comments | 7.3.49: This RE occurs across land zones on bedrock (excludes alluvial examples of Stanton and Stanton (2005) A50 which go into 7.3.25). Widespread across the bioregion. |
