Why are there so many wildfires?
Extreme weather events, marked by dry fuels, lightning storms and strong winds, are also increasingly common and provide essential ingredients for rapid fire growth, as witnessed by the Bootleg Fire burning in Oregon and record-setting fires in California and Colorado in 2020.
Why do wildfires start naturally?
Sometimes, fires occur naturally, ignited by heat from the sun or a lightning strike. However, most wildfires are because of human carelessness such as arson, campfires, discarding lit cigarettes, not burning debris properly, playing with matches or fireworks.

Why are there so many wildfires out west?
California, like much of the West, gets most of its moisture in the fall and winter. Its vegetation then spends much of the summer slowly drying out because of a lack of rainfall and warmer temperatures. That vegetation then serves as kindling for fires.
How does a campfire start a wildfire?
If a spark happens in the presence of oxygen and fuel—such as dry grass, brush or trees—a fire can start. And conditions in the weather and environment can cause the fire to spread quickly. Fires need lots of fuel to grow.

What causes lightning to start a fire?
