Uncontrolled rapid oxidation of flammable vegetation in rural countryside or wilderness areas
A wildfire, forest fire, bushfire, wildland fire or rural fire is an unplanned, uncontrolled and unpredictable fire in an area of combustible vegetation starting in rural and urban areas. Some forest ecosystems in their natural state depend on wildfire. Depending on the type of vegetation present, a wildfire can also be classified more specifically as a bushfire, desert fire, grass fire, hill fire, peat fire, prairie fire, vegetation fire, or veld fire. Wildfires are distinct from beneficial uses of fire, called controlled burns, though controlled burns can turn into wildfires.
