| Fire management guidelines | SEASON: Do not burn deliberately. c,d,e,g,h,i: 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. f: April-May or in some years through until Sep. INTENSITY: Do not burn deliberately. c,d,e,g,h,i: Low, with occasional moderate or high intensity to manage thickening and/or stimulate germination. f: Low to occasional moderate. INTERVAL: Do not burn deliberately. c,d,e,g,h,i: 2-5 years. f: 6-10 years. INTERVAL_MIN: 2. 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. c,d,e,g,h,i: 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. f: Mosaic burn 25-70% of the target area. Across the landscape burn different areas at different intervals to add diversity. 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. c,d,e,g,h,i: Low intensity fires at intervals > 5 years should be avoided, as these may promote an imbalance of rainforest. Infrequent high intensity fires will remove rainforest understorey and allow eucalypt germination, but high intensity fires may damage fire sensitive plants. f: Occasional moderate fire can assist management of overabundant tree recruitment. Too frequent fire can eliminate shrubs which require several years before they set seed. |
| Comments | 7.12.5: This regional ecosystem often occurs with a vine forest understorey, especially in areas where fire is infrequent. Most of the vine forest species present are fast-growing secondary species. This regional ecosystem may consist of pure stands of E. pellita (usually with a vine forest understorey), or may be more mixed species with E. pellita dominant or co-dominant. Widespread in eastern parts of the bioregion, particularly the Tully/Cardwell area and upper Herbert, the Yarrabah/Gordonvale area, and the Helenvale region. 7.12.5b: Well-developed vine forest understorey is probably a condition state caused by infrequent burning. 7.12.5d: Well-developed vine forest understorey is probably a condition state caused by infrequent burning. |
