Fire management guidelines SEASON: Cool, dry season (June-Sep). b: April-Sep. g: Early to mid-dry season in normal season (March-May). Early to late-season in wet year (March-Sep). INTENSITY: Low to moderate. g: Low to moderate. INTERVAL: 2-5 years. g: 3-10 years. INTERVAL_MIN: 2. INTERVAL_MAX: 10. STRATEGY: Mosaic burn < 30%. 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. g: Patch burn (<30% of area) early in the dry season to limit the extent and intensity of wildfires. Fires may, depending on the conditions and type of vegetation, burn areas larger than just the melaleuca ecosystem. Ensure secure boundaries from non fire-regime adapted ecosystems. Use topography to restrict spread of fire. Consider the needs of melaleuca ecosystems based on understorey (i.e., heath dominated, sedge dominated or mixed grass/shrub) when planning burns. High soil moisture (or presence of water on the ground) is required, as avoidance of peat-type fires must be maintained. ISSUES: Ignition is most likely during hot, dry season (Oct - Jan). These fires are typically high intensity fires that can be difficult to control. Maintaining a fire mosaic will ensure protection of animal habitats and mitigate against wildfires. b: An occasional moderate severity fire may be used to manage overabundant recruitment of trees. g: Restrict extent and intensity of fires. High intensity and extensive fires degrade vegetation structure and destroy animal habitats. Melaleuca forests are fire-adapted, but too high an intensity or frequent fire will slow or prevent regeneration and lead to lower species richness (since these communities contain numerous obligate seed regenerating species that require sufficient fire intervals to produce seed). High intensity fires may kill trees and lead to whipstick regeneration. Too frequent fire may result in a net loss of nutrients over time from an already nutrient poor system. Fire associations are significantly influenced by understorey composition.
Comments 7.5.4: Threatened by grazing and associated erosion. Central-western parts of the bioregion.
