Here's how wildfires get started—and how to stop them

One of the three conditions that make and sustain a fire must be removed. These conditions are fuel, air, or heat sources that could help spark the wildfire.

• One method is to douse existing fires with water or fire retardants.
• Another is to clear vegetation from the land around the fire - called a firebreak.
• Lastly is creating backfires, where firefighters fight fire with fire. These controlled fires remove undergrowth, brush, and litter that could fuel a fire.

Natural occurring wildfires play a vital part in nature. It burns decaying matter and can return trapped nutrients to the soil. It can act as a disinfectant by removing plant diseases and harmful insects.

Wildfires also thin forest canopies and undergrowth, enabling the sun to shine on the forest floor, helping new seedlings grow.
