Human activity is the primary cause of forest fires, accounting for over 90% of all fires.

Backfiring is not a method of fire suppression. It is a technique used to control the spread of a fire by setting a controlled fire in front of the main fire.

Forest management is the most effective way to prevent forest fires. It involves managing the forest to reduce the risk of fire, such as by thinning trees and removing dead wood.

Drones are not a type of forest fire suppression aircraft. They are unmanned aircraft that can be used for a variety of purposes, including fire surveillance and mapping.

The primary role of a forest firefighter is to extinguish fires. They do this by using a variety of tools and techniques, such as water, foam, and retardant.

Water is not a type of forest fire retardant. It is used to extinguish fires, but it does not prevent them from spreading.

Backfiring is not a type of forest fire suppression technique. It is a technique used to control the spread of a fire by setting a controlled fire in front of the main fire.

Fuel load is the most important factor in determining the severity of a forest fire. Fuel load is the amount of flammable material in a forest, such as trees, shrubs, and dead leaves.

Raking is not a type of forest fire behavior. It is a technique used to clear away flammable material from around a fire.

The primary role of a forest fire lookout is to detect fires. They do this by using a variety of tools, such as binoculars and telescopes, to scan the forest for smoke or flames.

Shovels are not a type of forest fire suppression tool. They are used to clear away flammable material from around a fire, but they are not used to extinguish fires.
