How wildfires start

Only 10 to 15 percent of wildfires arise on their own. The rest is caused by humans, such as unattended camp and debris fires, cigarettes, and arson.

Natural wildfires can occur during dry weather and droughts, where the vegetation becomes dry, flammable fuel. A spark in the form of lighting, arson, a burning campfire or a cigarette, even the hot sun can cause a spark, warm temperatures can cause combustion, and strong winds can spread fire quickly.
