Wildfire data were compiled from several sources, including the USDA Spatial Wildfire Occurence dataset and the NIFC Interagency Fire Perimeter dataset for fires before 2020, and the NIFC WFIGS and InFORM datasets for more recent fires. The dataset is likely incomplete for fires occurring before 1990.
