| Fire management guidelines | SEASON: After the wet season when rain is reliably expected and there is good soil moisture. Burning in the dry season (Oct-Dec) will give high intensity fires. b: Do not burn deliberately. a,c,d,f,h,i: Avoid dry conditions or fires will spread too much. April to July or as early as March, conditions permitting. INTENSITY: Low to moderate with occasional high to control overabundance of tree recruitment in mid-stratum. b: Do not burn deliberately. a,c,d,f,h,i: Moisture and topography affect severity. Low to high. INTERVAL: 3-5 years for grassy understorey. 6-10 years for shrubby understorey. b: Do not burn deliberately. a,c,d,f,h,i: 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. INTERVAL_MIN: 3. INTERVAL_MAX: 100. STRATEGY: Aim for a good fire coverage to limit forest transitioning. Do not target moist areas, such as in or near gullies as these will provide a mosaic of denser vegetation and refuge for some plant species. b: Maintain appropriate mosaic burning in surrounding country. Do not protect from fire but do not burn deliberately. a,c,d,f,h,i: 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. ISSUES: High intensity fires can be used to control an over-abundance of mid-storey recruitment; once controlled return to normal fire regime. Follow-up fires may be required to control more advanced tree recruitment (e.g., of rainforest pioneers). b: This is mainly a self protecting community. a,c,d,f,h,i: 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. |
| Comments | 7.11.32: Includes areas with a well-developed shrubby/heathy understorey i.e. Xanthorrhoea and Banksia, and areas without shrub/heath understorey. Distinguished from 7.11.6 by its occurrence on steep rocky slopes with shallow soils and its lower stature. Scattered along the ranges north from about Innisfail. 7.11.32c: Well-developed vine forest understorey is probably a condition state caused by infrequent burning. 7.11.32d: Minor components: 13f and 16f.
