Fire management guidelines SEASON: Avoid dry conditions or fires will spread too much. April to July or as early as March, conditions permitting. c,d,e,f: April-May or in some years through until Sep. INTENSITY: Moisture and topography affect severity. Low to high. c,d,e,f: Low to occasional moderate. INTERVAL: 6-10 years with some areas burnt at longer intervals. Fire intervals less than 6 years are too short to allow replenishment of obligate seeders. c,d,e,f: 6-10 years. INTERVAL_MIN: 6. INTERVAL_MAX: 10. STRATEGY: Mosaic burns will be achieved through use of natural features such as topography and creek-lines. Burn in association with surrounding vegetation. Protection relies on the broad-scale management of surrounding country with numerous small fires throughout the year so that wildfires will be very limited in extent. Fire exclusion and buffering from fire are not necessary. c,d,e,f: Mosaic burn 25-70% of the target area. Across the landscape burn different areas at different intervals to add diversity. ISSUES: Any planned burning should be conducted in association with plans for surrounding vegetation. Often contains obligate seed regenerating species and as such, the application of frequent fire may reduce species richness if the intervals between fire are not sufficient for plants to produce seed. Too frequent a fire frequency may result in a net loss of nutrients over time from an already nutrient poor system. Burn when water and moisture are present on the ground. c,d,e,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 7.12.26: Dense regeneration of understorey species such as Acacia flavescens and Allocasuarina littoralis are characteristic of disturbance. Generally experiences severe seasonal moisture deficits. Scattered throughout the bioregion but very common on the Cardwell Range and Hinchinbrook Island, also the Kirrama Range, Seaview Range, Yarrabah, and ranges west of Gordonvale. Susceptible to sheet and gully erosion. 7.12.26b: Well-developed vine forest understorey is probably a condition state caused by infrequent burning.
