The process of harvesting trees, sawing them into appropriate lengths (bucking), and transporting them (skidding) to a sawmill.
In the 19th century logging was a hand process, and in some parts of the world it has remained one. In colder regions, trees are felled by ax in winter and conveyed by a sled drawn by oxen, mules, or horses to a frozen river.
In mechanized modern logging, trees are felled by crosscut saw or power-driven chain saw or, for trees of relatively young plantations, by a machine that cuts the entire Tree in one bite. Trees are then cut into standard lengths and skidded to the mill by truck or tractor or conveyed to a central point by cable, either high above ground (high-lead and overhead skidding) or along the ground (groundline skidding). Helicopters and balloons are also used to transport logs.
