Controlled burn

 

 

Controlled or prescribed burning, also known as hazard reduction burning or swailing, is a technique sometimes used in forest management, farming, prairie restoration or green house gas  abatement. Fire  is a natural part of both forest and grassland ecology  and controlled fire can be a tool for forester.
Hazard reduction or controlled burning is conducted during the cooler months to reduce fuel buildup and decrease the likelihood of serious hotter fires. Controlled burning stimulates the germination  of some desirable forest trees, thus renewing the forest. Some cones , such as those of Lodgepole pine  and Sequoia , are serotinous , meaning they require heat from fire to open cones to disperse seeds.
