Glossary
assortment method: The trees are cut to assortments of up to approximately 4 m in length in the stands and transported, usually by hand, to the skidding corridor or the haul road.
final cut: Removal of aged trees in different silvicultural systems (clearcut, shelterwood, selective cutting).
final cut area: Area, where final cut takes place.
full-length method: Delimbing and trimming take place in the stand, whereas bucking and final limbing are carried out only after skidding. Skidding itself can be either by the interrupted or by the continuous transport method.
harvesting method: The harvesting method is named according to the form in which the timber gets logged; e.g. whole-tree method, full-length method, assortment method.
harvesting system: The harvesting system is named according to its stage of mechanization; i.e. partially-, highly-, or fully-mechanized timber harvesting.
hauling: Transport of timber done by means of trucks on roads.
hoisting equipment: All kinds of equipment used to join the load to the hook (here: two ropes with log tongs at their ends and connected to a synthetic sling).
hook-block: Block with integrated hook.
logging: Transport of timber from the stand to the landing done by means of skidders or yarders.
modified full-length method: Delimbing and trimming take place in the stand; only bucking is carried out after skidding. Skidding itself can be either by the interrupted or by the continuous transport method.
processing: Delimbing, cross-cutting (= bucking) and storage are carried out by processors after skidding.
whole-tree method: Felling and trimming are done in the stand. Skidding is to the skidding corridor or the forest road, where processors are used for mechanical conversion.
