Prescribed fire is a planned fire, and is used to meet management objectives. A prescription is a set of conditions that considers the safety of the public and fire staff, weather, and the probability of meeting the burn objectives. Prescribed fire is one of the most important tools used to manage fire today. A scientific prescription for each fire - prepared in advance- describes its objectives, fuels, size, the precise environmental conditions under which it will burn, and the conditions under which it may be suppressed. The fire may be designed to create a mosaic of diverse habitats for plants and animals, to help endangered species recover, or to reduce fuels and thereby prevent a destructive fire. Every fire is under very strict controlled measures where the wildlife is completely safe for the most.
