Pruning is removing the lower branches of trees. Increasing the distance between the ground and the lowest tree branches reduces the likelihood that a fire on the ground will use the branches as a ladder to move into tree crowns. A crown fire is more difficult to control and can advance much more rapidly than a surface fire, under certain weather conditions.Pruning is a particularly effective fuels-reduction technique when combined with other forms of treatment such as thinning.
