In forest and prairie management, the driptorch is the most common tool used to ignite prescribed burns, which are used to remove excess fuel buildup or to re-create natural cycles of fire in an ecosystem .
By the 1980s, in light of this new understanding, funding efforts began to support prescribed burning in order to prevent wildfire events. [3] In 2001, the United States implemented a National Fire Plan, increasing the budget for the reduction of hazardous fuels from $108 million in 2000 to $401 million. [4]
