Wildfire spatial patterns are determined by fire ignition sources and vegetation fuel moisture. Fire ignitions can be: (1) human-mediated – due to proximity to human infrastructure, or (2) lightning-caused – due to fuel moisture, average annual rainfall and local weather. When moisture in dead vegetation is below 20 % the probability of a wildfire increases. The results of this research enable accurate spatial mapping of ignition probability to aid in fire suppression efforts and future research.
