The California Wildfire & Forest Resilience Task Force (Task Force) is producing a toolkit that can support organizations to prioritize, plan and implement actions to lessen wildfire risk to communities and improve broader statewide ecosystem resilience. As part of this effort, a core set of metrics needed to be identified to report resilience progress. The Task Force's Science Advisory Panel engaged in a rapid Delphi process, collecting expert opinion via surveys to provide content knowledge and science support for this process. This data archive provides content 1) for transparency, to share as much of our workflow as is feasible; 2) for others to pull from as an example if they want to do a similar process; 3) to provide all the detailed results on metrics if a reader wants to look into the ratings for and definition of a particular metric. The archive supports a report and paper summarizing and describing our Delphi method and the results regarding the specific metrics considered by our experts.
