| Fire management guidelines | SEASON: Late summer to winter. a. Late summer to autumn. INTENSITY: Low to moderate. a. Moderate to high. INTERVAL: 7-25 years. a. Minimum 20 years, maximum unknown, requiring further research. INTERVAL_MIN: 7. INTERVAL_MAX: 100. STRATEGY: Aim for a burn mosaic of 40-60% over the burn area. A diversity of season and fire intensity is important, as well as spot ignition in cooler or moister periods to encourage mosaics. Late summer burns assist with maintaining control of fire intensity. a. Needs disturbance to maintain RE structure (eucalypt overstorey, rainforest dominated but mixed species understorey). It is unlikely that mosaic burns will be achievable because fire would most likely be of higher intensity (i.e., likely to be a wildfire) and is only likely to occur at long intervals (at least 20+ years) during prolonged dry periods. In exceptional circumstances, different localities containing this ecosystem could be burnt to ensure a continuum of habitat availability across the broader landscape. Using this strategy maximises the probability of spatial mosaics in the landscape. ISSUES: Fires that are too frequent will eliminate obligate seeding species. Fire frequency should be such as to allow obligate to reach maturity and produce viable seed. a. Operationally there will be many areas of wet sclerophyll that cannot be safely burnt, and will only burn in wildfire. There is evidence that suggests that infrequent high intensity fires sustain the eucalypt overstorey. Wet sclerophyll has been shown to be a moving ecotone between vine forest and moist/dry sclerophyll. |
