The fire management community has embraced the concept of risk assessment for all fire and fuels management activities, and geospatial analysis tools are commonly used to map where fire is likely to cause damage. Forest Service scientists are adapting these concepts and tools for use in the wilderness context, where the goal of fire management is to allow fire to play its natural ecological role. They used spatial risk analysis tools to map the likelihood that an unplanned ignition in wilderness would escape the wilderness boundary or reach the wildland-urban interface and to identify where and when “windows of opportunity” exist for allowing wilderness fires to burn. Importantly, these maps can reveal opportunities for managing wildfires for their resource benefits and thus integrate well with land management plans and spatial fire management plans. In addition, output from the analysis can be used to summarize escape probability in terms of escaped fire size, distance to the boundary, and month of ignition. They propose to refine and streamline these methods so that maps depicting “windows of opportunity” can be readily generated for any management unit and be used to inform forest and fire management planning.
