logging

Logging is the process in which certain trees are cut down for forest management and timber.

In forestry the term logging is sometimes used in a narrow sense concerning the logistics of moving wood from the stump to somewhere outside the forest, usually a sawmill or a lumber yard. In common usage however the term may be used to indicate a range of forestry or silviculture activities. For example the practice of the removal of valuable trees from the forest has been called selective logging, sometimes confused with selection cut.

Illegal logging refers to what in forestry might be called timber theft.

In common usage what is sometimes called clearcut logging is not is necessarily considered a type of logging but a harvest or silviculture method and is simply called clearcutting or block cutting. In the forest products industry logging companies may be referred as logging contractors.

Logging usually refers to above-ground forestry logging. Submerged forests exist on land that has been flooded by damming to create reservoirs. Such trees are logged using underwater logging or by the lowering of the reservoirs in question. Ootsa Lake and Williston Lake in British Columbia, Canada, are notable examples where timber recovery has been needed to remove inundated forests.
