Limbing or delimbing is the process of removing branches from a standing or fallen tree trunk.[1]
In logging, limbing follows felling.[2] Limbing plays a role in fire prevention by removing branches from live trees that can otherwise serve as part of a fuel ladder allowing a fire to climb from the ground into the tree canopy. A California fire prevention guide recommends to "Remove all tree branches at least 6 feet [1.8 meters] from the ground" and "Allow extra vertical space between shrubs and trees."[3]
In British English, limbing can be synonymous with snedding. Alternatively, limbing can be used to describe the operation on larger branches, and snedding on smaller.
