How Forest Fires Start
Three elements are required in order for a forest fire to start: fuel, oxygen, and a heat source. Fuel is any flammable material, and a forest is full of these—trees, brush, grass, and small cabins. The air provides oxygen, and both humans and the environment have the ability to provide the heat source.
Types of Forest Fires
There are two different types of forest fires: surface fires and crown fires. Surface fires spread along the ground of the forest. Twigs, dry leaves, and other debris are engulfed in flames as it spreads. Crown fires burn trees up their entire length and spread quickly through the canopy.
How Are Forest Fires Fought and Contained?
Forest fires are contained by a wide variety of strategies, depending on the location and size of the fire.

Environmental Impact of Forest Fires
Forest fires are often devastating to the environment. Ground cover is necessary to protect the soil. If all of this vegetation is burned away, the soil is left exposed to the elements. Heavy rain can degrade soil and cause flooding and erosion.

One positive effect of a forest fire is that the forest floor is less combustible.

What does a forest fire do to the forest?
A controlled forest fire creates hollows in logs and improves vegetation conditions. What does this mean for the forest?

How does burning out undergrowth help the forest?
Burning out this undergrowth can lead to more productive growth because it adds potash—a potassium-rich salt—to the soil. This increases the nutrients in the soil. When fresh soil with fresh nutrients replaces old soil with far fewer nutrients, it can rejuvenate trees in the forest. This can be of major benefit to any creature inhabiting the forest. This fresh soil growing is an example of slash and burn agriculture and is more conducive to producing higher-quality vegetation than the old soil would have been.
