Logging is the process of cutting down trees, an element of the logging task. The person who cuts down the trees is a feller. A feller buncher is a machine capable of cutting down a single large tree or grouping and cutting down several small ones simultaneously. Directional felling is a specific tree cutting technique in which the operator determines the direction of fall before cutting.
Wherever possible, trees should be cut down in the direction of existing gaps in the canopy to reduce damage to nearby standing wood. In general, trees should be felled towards or away from the skating rinks, preferably at an oblique angle to the sliding direction. Felling away from the slide path will reduce problems for the extraction team when the treetops are large, while felling to the slide path can substantially reduce the extraction distance. Felling and removal, of all or nearly all commercial trees and trees in size classes immediately below the commercial category that provide the next harvest, from a specific area in an operation.
In selection collection systems (polycyclic), the planned number of years between successive harvests in a forest area. The harvesting activity occurs at the end of the cutting cycle. It is also known as the felling cycle. If there are power lines near the tree, do not attempt to cut down the tree unless you are absolutely sure that doing so will not interfere with them.
Some secondary forest species are found in the tropics, and others grow in open spaces by rivers, in ancient landslides, in hollows caused by the fall of dead trees or trees, or where the forest has been knocked down by severe storms. There is a copper plaque depicting dragging the prisoner with ropes, and cutting him down with a club. A forest regeneration system that opens the canopy through small groups of felling (small crops) that create spaces where regeneration can occur is often referred to as a group selection harvest practice. Presented by Scandinavian logging specialists, this cut is easier to make, provides good guidance and has additional safety features.
Left and right, each one cutting down his man; and the cimeters came out of his hands like stubble, the shields struck each other as if they were gauze. Average number of scrubland shoots after 1 and 6 years of regrowth on stumps of three species that were 6-year-old shoots when they were cut down in February, April or June 1993a. If that is not possible, drop the tree from a position where the limbs cannot hit it if they break off. Unfortunately, secondary forest is becoming increasingly important in the Amazon due to the amount of primary forest clearing that is taking place.
Harvesting systems in which crop trees are removed in a cycle based on a cycle of felling inputs that occur more frequently than a rotation according to cutting limits or other criteria. Tool inserted into the rear cut during felling to provide a lever that forces the tree to fall in a certain direction. Average length of the three longest shoots growing from stumps of 6-year-old young trees of ash (Fraxinus excelsior), oak (Quercus robur) and sycamore (Acer pseudoplatanus) felled in February or June 1993.Sanitation involves the identification of trees infested by bark beetles and the subsequent felling and removal or treatment to destroy adults and young under the bark, thus reducing their populations.
