Logging involves cutting down trees and transporting them to sawmills, pulp mills and other woodworking enterprises. Based on the planning system, a decision is made when and which parts of the forest will be felled and how this will happen, so that all these activities are carried out in accordance with the protection of social and environmental values.
While a century ago, logging was almost entirely dependent on economic considerations, there are other factors today. The main purpose of harvest planning is to harvest the oldest timber first. In addition, timber industries have a vested interest in securing timber supplies as cheaply as possible. These two requirements can be met by analyzing forest inventory data that identifies the different species of species, their age, and how they are updated.
Although technology has significantly improved safety, felling remains one of the most dangerous professional activities in the world. Special machines here (harvesters) using harvester heads for cutting trees. Special equipment also cuts branches and sorts the timber for further transportation. A power cut is safer than using a chainsaw. Hand chain saws are still widely used today, although they are most commonly found in heavy tree operations.
Skidding involves dragging logs or trees to the side of the road using a skid wheel or forwarder. These machines are used in virtually all commercial forestry operations. The forwarders are equipped with high-density tires and an all-wheel drive system.
The way logs are transported from the forest to factories for further processing depends on the location. The water method is widespread. The logs are either formed into rafts or loaded onto barges and then towed to the factory. In addition, trees are often moved by truck or rail.
