How wildfires happen

For wildfire to occur, three conditions must be present – heat, fuel, and oxygen. Since wild nature occupies vast spaces under the sky – oxygen is always present. It feeds the fire but also helps the flames to spread in an uncontrolled way.

Fuel is combustible material, something that can be burnt. Dry leaves, grasses, old trees or even green vegetation serve as fuel.

The heat comes to sun, hot air, lightning strike, or when a fire is set by man.
