The National Park Service sometimes creates controlled burns to mitigate wildfires.

a wildfire start and spread.
A controlled burn temporarily shuts down parks so people won't start
campfires.
A controlled burn is used to make a path that helps a spreading
wildfire arrive at a source of water.
A controlled burn helps to remove plants and vegetation around
buildings so a wildfire won't destroy them.
