What are the 3 types of wildfires?

Ground fires typically start in soils filled with organic matter that can fuel flames, such as plant roots. Ground fires can burn for a long time, even an entire season, until conditions are right for them to grow into a surface or crown fire.

Surface fires burn in dead or dry vegetation that is located or growing just above ground. Parched grass and fallen leaves often fuel surface fires.

Crown fires burn in the leaves and canopies of trees and shrubs.
