Wildfire is a natural part of a desert ecosystem, but it becomes problematic when it impacts people or destroys habitat. Wildfire can happen any month in Arizona, but most wildfires occur March through June. Wildfiire can be initiated by natural events such as lightning, or by human events, such as campfires, downed powerlines, or parking a car over dry brush. Monsoon thunderstorms can initiate wildfires if there is lightning with limited precipitation (sometimes called “dry lightning”).
