Oxen were at first used with the high-wheel loaders, but in the 1930s tractors replaced the oxen. (Some logs sink because of high resin content these are called deadheads.) In the late 1800s and the first half of the 1900s, the most common method was the high-wheel loader, which was a set of wheels over ten feet tall that the log or logs were strapped beneath. The cheapest and historically most common method is making use of a river's current to float floating tree trunks downstream, by either log driving or timber rafting. Many methods have been used to move logs from where they were cut to a rail line or directly to a sawmill or paper mill.

This technique removes both nutrients and soil cover from the site and so can be harmful to the long-term health of the area if no further action is taken, however, depending on the species, many of the limbs are often broken off in handling so the end result may not be as different from tree-length logging as it might seem. Full-tree harvesting also refers to utilization of the entire tree including branches and tops. In areas with access to cogeneration facilities, the slash can be chipped and used for the production of electricity or heat. This method requires that slash be treated at the landing. The trees are then delimbed, topped, and bucked at the landing. This ability is due to the advancement in the style felling head that can be used. There have been advancements to the process which now allows a logger or harvester to cut the tree down, top, and delimb a tree in the same process. Trees and plants are felled and transported to the roadside with top and limbs intact. Ĭable logging in French Alps (cable grue Larix 3T) Ootsa Lake and Williston Lake in British Columbia, Canada are notable examples where timber recovery has been needed to remove inundated forests. Such trees are logged using underwater logging or by the lowering of the reservoirs in question. Submerged forests exist on land that has been flooded by damming to create reservoirs. Logging usually refers to above-ground forestry logging. It is sometimes called selective logging, and confused with selection cutting, the practice of managing stands by harvesting a proportion of trees. Cutting trees with the highest value and leaving those with lower value, often diseased or malformed trees, is referred to as high grading. Ĭlearcutting (or “block cutting“) is not necessarily considered a type of logging but a harvesting or silviculture method. It may involve the so-called “ timber mafia”. The harvesting procedure itself may be illegal, including the use of corrupt means to gain access to forests extraction without permission or from a protected area the cutting of protected species or the extraction of timber in excess of agreed limits. Illegal logging refers to the harvesting, transportation, purchase, or sale of timber in violation of laws. In common usage, however, the term may cover a range of forestry or silviculture activities. In forestry, the term logging is sometimes used narrowly to describe the logistics of moving wood from the stump to somewhere outside the forest, usually a sawmill or a lumber yard. Logging systems are also used to manage forests, reduce the risk of wildfires, and restore ecosystem functions. Logging is the beginning of a supply chain that provides raw material for many products societies worldwide use for housing, construction, energy, and consumer paper products.
It may include skidding, on-site processing, and loading of trees or logs onto trucks or skeleton cars. Logging is the process of cutting, processing, and moving trees to a location for transport. McGiffert Log Loader in East Texas, USA circa 1907
