California Department of Forestry and Fire Protection (CAL FIRE) - Fire and Resource Assessment Program (FRAP) Annual fire probability data for California was developed and provided to CAL FIRE by Joe Scott, Pyrologix Inc. Fuel Rank data was developed in 2005 by CAL FIRE-FRAP, and updated for 2014 using the FRAP California Interagency Fire Perimeter Database (fire16_1). CAL FIRE recognizes the various partners that have contributed to this dataset, including USDA Forest Service Region 5, USDI Bureau of Land Managment, National Park Service, National Fish and Wildlife, and numerous local agencies. Existing vegetation data used in formulation of Fire Threat were from the FRAP Existing Vegetation dataset, which was developed in cooperation with California Department of Fish and Wildlife VegCamp program and the USDA Forest Service Region 5 Remote Sensing Laboratory (RSL).
