“Wildfire” is a term applied to any unwanted, unplanned, damaging fire burning in forest, shrub, or grass. While sometimes caused by lightning, nine out of ten wildfires are started by humans. Chainsaws, dragging trailer chains, carelessly tossed cigarettes, fireworks, abandoned campfires and firearm discharges can all cause wildfires.
Note: fireworks and incendiary devices (such as exploding targets and exotic ammunition) are NOT ALLOWED on federal public lands at any time. This includes National Forests, Bureau of Land Management sites, and National Parks and Monuments.
