A planned and supervised burn carried out under specified environmental conditions to remove fuel from a predetermined area of land and at the time, intensity and rate of spread required to meet land management objectives. There are three specific types of prescribed burn which are used for restoration activities: (1) Conversion burn - The use of fire to eliminate unwanted species that have appeared through natural regeneration. The ultimate purpose of conversion burning is usually to prepare an area for planting or to introduce different species. (2) Regeneration burn - The use of fire to promote the natural regeneration of species which need heat/fire to release their seeds or to break a period of dormancy. (3) Site preparation burn - The use of fire to remove slash left after the logging of burned timber. The purpose of a site preparation burn is to prepare an area for other regeneration activities
