*Our model attributed the greatest percentage of 150,247 wildfires from 1992 to 2020 for which the ignition source was unknown to equipment and vehicle use (21%), lightning (20%), and arson and incendiarism (18%).

*Our model more accurately separated wildfires ignited by natural versus human causes (93% accuracy), and discriminated among the 11 classes of human-ignited wildfires with 55% accuracy.

*ML models can identify the cause of wildfire ignitions and determine the contributions of diverse attributes to classification of cause
*Trained on wildfires from 1992 to 2020 with 12 known causes, the overall accuracy of our model exceeded 70% when applied to out-of-sample test data.

*The spatial and temporal distribution of wildfires is captured by associated biological, physical, social, and management attributes
*Wildfires are increasingly reported with an unknown cause (5-fold increase from 1992 to 2020), hindering targeted prevention strategies
