Cut-to-length logging

Last updated

Cut-to-length logging (CTL) is a mechanized harvesting system in which trees are delimbed and cut to length directly at the stump. [1] 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.

The capital costs for a typical CTL operation, with one harvester and one forwarder, are quite high. The price of a pair of machines alone are approx. US$1,000,000.

CTL is the primary logging method in European countries, [4] while full-tree logging and the even older technique of tree-length logging are more popular in North America and less developed countries, where tree sizes can exceed the capacity of the harvester's felling head, i.e., tree stems with a butt diameter of over 90 centimeters.[ citation needed ] CTL lends itself to timber harvesting in plantation forestry where stems are often harvested before they reach large dimensions.

<span class="mw-page-title-main">Logging</span> Process of cutting, processing, and moving trees

Logging 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.

Lumberjack is a mostly North American term for workers in the logging industry who perform the initial harvesting and transport of trees. The term usually refers to loggers in the era before 1945 in the United States, when trees were felled using hand tools and dragged by oxen to rivers.

<span class="mw-page-title-main">Skidder</span> Type of heavy vehicle used in logging operations to pull cut trees out of a forest

A skidder is any type of heavy vehicle used in a logging operation for pulling cut trees out of a forest in a process called "skidding", in which the logs are transported from the cutting site to a landing. There they are loaded onto trucks, and sent to the mill. One exception is that in the early days of logging, when distances from the timberline to the mill were shorter, the landing stage was omitted altogether, and the "skidder" would have been used as the main road vehicle, in place of the trucks, railroad, or flume. Modern forms of skidders can pull trees with a cable and winch, just like the old steam donkeys, or with a hydraulic grapple either on boom or on the back of the frame (clambunk skidder).

<span class="mw-page-title-main">Forwarder</span> Vehicle used in forestry

A forwarder is a forestry vehicle that carries big felled logs cut by a harvester from the stump to a roadside landing for later acquisition. Forwarders can use rubber tires or tracks. Unlike a skidder, a forwarder carries logs clear of the ground, which can reduce soil impacts but tends to limit the size of the logs it can move. Forwarders are typically employed together with harvesters in cut-to-length logging operations. Forwarders originated in Scandinavia.

A feller buncher is a type of harvester used in logging. It is a motorized vehicle with an attachment that can rapidly gather and cut a tree before felling it.

<span class="mw-page-title-main">Harvester (forestry)</span> Type of forestry vehicle employed in logging operations

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, for a forwarder to pick up and haul away.

Silviculture is the practice of controlling the growth, composition/structure, as well as quality of forests to meet values and needs, specifically timber production.

<span class="mw-page-title-main">Log bucking</span> Process of cutting a felled and delimbed tree into logs

Bucking is the process of cutting a felled and delimbed tree into logs. Significant value can be lost by sub-optimal bucking because logs destined for plywood, lumber, and pulp each have their own value and specifications for length, diameter, and defects. Cutting from the top down is overbucking and from the bottom up is underbucking.

Sakari Pinomäki (1933–2011) was a Finnish systems engineer and an inventor, who pioneered the mechanized forestry industry. He was the founder of PIKA Forest Machines which produced the first purpose-built forest machine in 1964 in Ylöjärvi , Finland. His inventions had over 50 patents.

<span class="mw-page-title-main">Felling</span> Process of cutting down trees

Felling 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.

Underwater logging is the process of logging trees from underwater forests. When artificial reservoirs and dams are built, large areas of forest are often inundated; although the trees die, the wood is often preserved. The trees can then be felled using special underwater machinery and floated up to the surface. One such machine is the sawfish harvester. There is an ongoing debate to determine whether or not underwater logging is a sustainable practice and if it is more environmentally sustainable than traditional logging.

<span class="mw-page-title-main">Heli-logging</span>

Heli-logging, or helicopter logging, is a method of logging that uses helicopters to remove cut trees from forests by lifting them on cables attached to a helicopter. Helicopter logging is often used in inaccessible areas of forests. Because the use of helicopters reduces the level of infrastructure required to log in a specific location, the method also helps to reduce the environmental impact of logging. It also can increase the productivity in these remote areas.

<span class="mw-page-title-main">Firewood processor</span> Cutting machine

A firewood processor is a machine designed to cut and split firewood with minimal manual handling of the logs. There are typically four main parts of the machine, each dedicated to a separate function. Processing begins with a log pile – a pile of logs that have been de-limbed and cut to an appropriate length, generally 12–20 feet (3.7–6.1 m). Popular brands include DYNA, Multitek, Eastonmade, Cord King, Wood Beaver, Hakki Pilke, and Blockbuster. Many individuals use processors commercially, while some use them privately as a hobby. If someone has a small amount of wood they'd like to split but don't want to spend a lot of money, there's options to rent processors as an alternative to purchasing.

<span class="mw-page-title-main">Tree plantation</span> Type of forest planted for high volume production of wood

A tree plantation, forest plantation, plantation forest, timber plantation or tree farm is a forest planted for high volume production of wood, usually by planting one type of tree as a monoculture forest. The term tree farm also is used to refer to tree nurseries and Christmas tree farms. Plantation forestry can produce a high volume of wood in a short period of time. Plantations are grown by state forestry authorities and/or the paper and wood industries and other private landowners. Christmas trees are often grown on plantations, and in southern and southeastern Asia, teak plantations have recently replaced the natural forest.

<span class="mw-page-title-main">Skidding (forestry)</span> Transportation of trees in logging

Skidding in forestry is the first operation after logging: it consists of transporting felled trees from the felling site to a temporary dumping site, known technically as a "loader", near a road or track suitable for further transport. This name is still applied to the first emptying of stones in quarries or stone heaps and possibly heavy equipment in mines, to heavy transport operations and cumbersome handling.
