In many wildland areas, smoke can often be seen throughout the winter. More than likely, this is not due to uncontrolled wildfire, but rather prescribed fires that are started when the weather is less conducive to catastrophic burns, allowing firefighters and crews to prepare for when wildfire season picks up again.

Prescribed fire is one of the most effective mitigation concepts for reducing the outbreak and spread of wildfires. SmokeyBear.com defines prescribed fire as the controlled application of fire by a team of fire experts under specified weather conditions that help restore health to fire-adapted environments. Prescribed fires can sometimes be confused with “backfiring” or “controlled burning” which typically refer to different types of prescribed and controlled fires. In many cases by safely reducing excessive amounts of brush, shrubs, and trees, prescribed burning can help reduce the catastrophic damage of wildfire on wildlands and surrounding communities.
In the Golden Hills photo above, the piling and burning of excess fuel was intended to make the fire road safer (this technique is sometimes called road brushing) and also to provide a fire break between Hwy 58 (a major thoroughfare) and the densely populated Golden Hills community.
