Fires can travel quickly: up to 6 miles-per-hour in forests and up to 14 miles-per-hour in grasslands. If you have an upward-slope to your terrain, the flames can travel even faster; an extra 10 degrees of slope will double the speed of your fire.
What is the most common way for a wildfire to start?
Nearly 85 percent* of wildland fires in the United States are caused by humans.

Is it easy to start a forest fire?
The conditions do not have to be too crazy for a wildfire to start. Wildfires can start with something as random and unpredictable as a lightning strike hitting a tree.

Why don t fires stop immediately as soon as they start?

Why don’t trees catch fire and burn all the time?
Thick bark. Trees in fire-prone areas develop thicker bark, in part, because thick bark does not catch fire or burn easily. It also protects the inside of the trunk, the living tissues that transport water and nutrients, from heat damage during high-frequency, low-intensity fires.
