A methodology for State-wide mapping of annual fuel load and bushfire hazard in Queensland

[摘要] This document describes a method for mapping Annual Fuel Load (AFL) and Annual Bushfire Hazard (ABH) for Queensland. This approach builds on methods implemented for mapping Bushfire Prone Areas (BPA) including Potential Bushfire Hazard (PBH), in support of Queensland’s State Planning Policy (Department of State Development, Infrastructure and Planning, 2014) to guide planning and development in bushfire prone areas (Leonard et. al. 2014). AFL and ABH mapping are inputs to the preparation of bushfire mitigation plans and bushfire risk plans prepared by Government and various fire management organisations. The mapping has further potential for use in other initiatives such as community warnings, prioritising of planned burns, fire behaviour modelling and resource allocation projects.AFL and ABH models modify estimates of Potential Fuel Load (PFL) and PBH by reducing fuel loads based on an assumed consumption of fuel from mapped wildfires or planned burns over 27 years (1987-2014), and by taking into account the time since the burn and the return of fuel load to its full potential. While these models can be applied once each year to reflect the accumulated reduction of fuel from all identified fires, it is technically feasible to also apply these models at more frequent intervals if needed. As a starting point for further testing and validation of model outputs, there would be benefit in apply models in January each year at the end of the wildfire season and hazard mitigation season, in preparation for the planning of future activities.
