| Fire management guidelines | SEASON: Early (as soon as fire will carry after rain), then late dry season (storm burns, Nov-Dec). INTENSITY: Moderate to high. INTERVAL: 6-10 years. INTERVAL_MIN: 6. INTERVAL_MAX: 10. STRATEGY: Burn progressively in a mosaic of <30% of area. 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 the fire mosaic. If burning these ecosystems using high intensity fire then protect adjacent communities using secure perimeter burns. ISSUES: Low intensity fires at intervals > 5 years should be avoided, as these may promote rainforest development that could affect sclerophyll regeneration. Low intensity fires at intervals < 5 years may not spread well owing to poor fuel accumulation and produce inadequate fire mosaics. Grazing pressure may need to be alleviated in the year before burning to ensure carriage of fire at intervals < 5 years. Infrequent high intensity fires will remove rainforest understorey and allow eucalypt germination, but high intensity fires may be difficult to manage. Wildfires occurring under hot conditions within this vegetation type are beneficial for its regeneration, but would need containment so that they do not escape into surrounding drier forests. Fire management that reduces the complexity of the understorey by removing plant species, structural layering and fallen woody debris will reduce overall diversity of plants and animals. Depending on site location, history and/or soil (e.g., low nutrient soils) it may be possible to leave some areas long unburnt and maintain a diverse understorey without problems of woody thickening that will lead to conversion of wet sclerophyll to rainforest. |
| Comments | 7.12.52: Occurs at lower altitudes and drier areas than 7.12.22, and distinguished from 7.12.22 by its medium (as opposed to tall) stature, and common occurrence of species such as Eucalyptus drepanophylla and E. reducta. Similar to 7.12.51 but occurs in both the central-west and south of the bioregion (rather than only the far south), and has different associated species such as E. reducta. Distinguished from 7.12.57 by its woodland structure as opposed to a shrubland. From west of the Atherton Tablelands south to the Paluma Range. |
