Cut-to-length loggingCut-to-length logging (CTL) is a mechanized harvesting system in which trees are delimbed and cut to length directly at the stump. CTL is typically a two-man, two-machine operation with a harvester felling, delimbing, and bucking trees and a forwarder transporting the logs from the felling to a landing area close to a road accessible by trucks.
SneddingSnedding is the process of stripping the side shoots and buds from the length of a branch or shoot, usually of a tree or woody shrub. This process is most commonly performed during hedge laying and prior to the felling of trees on plantations ready for cropping. The verb 'sned', analogous to today's limbing, has also been used by woodcutters in Scotland to refer to the process of removing branches from felled trees.
FellingFelling is the process of cutting down trees, an element of the task of logging. The person cutting the trees is a lumberjack. A feller buncher is a machine capable of felling a single large tree or grouping and felling several small ones simultaneously. MethodsHand fellingIn hand felling, an axe, saw, or chainsaw is used to fell a tree, followed up by limbing and bucking in traditional applications.
Tree stumpA tree stump is the remaining portion of a treetrunk and its roots that remain after a tree has been felled or has naturally fallen. The roots often remain largely intact underground. The cross section of a tree stump shows the annual growth rings that can reveal the tree's age, growth patterns, and environmental conditions during its lifetime. The scientific study of these rings, known as dendrochronology, can reveal historical climate information.
Potential energyIn physics, potential energy is the energy of an object or system due to the body's position relative to other objects, or the configuration of its particles. The energy is equal to the work done against any restoring forces, such as gravity or those in a spring. The term potential energy was introduced by the 19th-century Scottish engineer and physicist William Rankine, although it has links to the ancient Greek philosopher Aristotle's concept of potentiality.
Harvester (forestry)A harvester is a type of heavy forestry vehicle employed in cut-to-length logging operations for felling, delimbing and bucking trees. A forest harvester is typically employed together with a skidder that hauls the logs to a roadside landing, or a forwarder to pick up and haul away.
LoggingLogging is the process of cutting, processing, and moving trees to a location for transport. It may include skidding, on-site processing, and loading of trees or logs onto trucks or skeleton cars. 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. In common usage, however, the term may cover a range of forestry or silviculture activities.
BranchA branch, also called a ramus in botany, is a stem that grows off from another stem, or when structures like veins in leaves are divided into smaller veins.
Trunk (botany)Trunks, also called boles, are the stems of woody plants and the main structural element of trees. The woody part of the trunk consists of dead but structurally significant heartwood and living sapwood, which is used for nutrient storage and transport. Separating the wood from the bark is the cambium, from which trunks grow in diameter. Bark is divided between the living inner bark (the phloem), which transports sugars, and the outer bark, which is a dead protective layer.Fire preventionFire prevention is a set of proactive methods/practices to prevent fire-based emergencies and minimize the damage caused to the surrounding environment by them. There are two priority focuses of fire prevention: eliminating the factors that cause them, or controlling the conditions at which a fire can be born. These methods aim to significantly reduce the frequency or extremity of a fire.
Fuel ladderA fuel ladder or ladder fuel is a firefighting term for live or dead vegetation that allows a fire to climb up from the landscape or forest floor into the tree canopy. Common ladder fuels include tall grasses, shrubs, and tree branches, living and dead. The removal of fuel ladders is part of defensible space 'firescaping' practices.British EnglishBritish English is the set of varieties of the English language native to the United Kingdom, especially Great Britain. More narrowly, it can refer specifically to the English language in England, or, more broadly, to the collective dialects of English throughout the United Kingdom taken as a single umbrella variety, for instance additionally incorporating Scottish English, Welsh English, and Northern Irish English.
