Hydraulic debarker. A hydraulic debarker is a machine removing bark from wooden logs by the use of water under a pressure of 700 kilopascals (100 pounds per square inch) or greater. [1] Hydraulic debarking can reduce soil and rock content of bark, but may increase the water content. Debarking water may be recycled after effective settling, but ...
Girdling, also called ring-barking, is the circumferential removal or injury of the bark (consisting of cork cambium or "phellogen", phloem, cambium and sometimes also the xylem) of a branch or trunk of a woody plant. Girdling prevents the tree from sending nutrients from its foliage to its roots, resulting in the death of the tree over time ...
Debarker machine. Manually decorticated trunk of a spruce as protection to bark beetles. Debarking is the process of removing bark from wood. Traditional debarking is conducted in order to create a fence post or fence stake which would then go on to be pointed before being planted. [1] Debarking can occur naturally during powerful tornadoes.
Gravitropism (also known as geotropism) is a coordinated process of differential growth by a plant in response to gravity pulling on it. It also occurs in fungi. Gravity can be either "artificial gravity" or natural gravity. It is a general feature of all higher and many lower plants as well as other organisms.
Krummholz Pinus albicaulis in Wenatchee National Forest Wind-sculpted krummholz trees, Ona Beach, Oregon. Krummholz (German: krumm, "crooked, bent, twisted" and Holz, "wood") — also called knieholz ("knee timber") — is a type of stunted, deformed vegetation encountered in the subarctic and subalpine tree line landscapes, shaped by continual exposure to fierce, freezing winds.
Decision tree pruning. Pruning is a data compression technique in machine learning and search algorithms that reduces the size of decision trees by removing sections of the tree that are non-critical and redundant to classify instances. Pruning reduces the complexity of the final classifier, and hence improves predictive accuracy by the ...
According to CODIT, when a tree is wounded cells undergo changes to form "walls" around the wound, slowing or preventing the spread of disease and decay to the rest of the tree. Wall 1. The first wall is formed by plugging up normally conductive vascular tissue above and below the wound. This tissue runs up and down the length of the stem, so ...
Drunken trees, tilted trees, or a drunken forest, is a stand of trees rotated from their normal vertical alignment. [ 1 ] [ 2 ] This most commonly occurs in northern subarctic taiga forests of black spruce ( Picea mariana ) under which discontinuous permafrost or ice wedges have melted, [ 3 ] [ 4 ] causing trees to tilt at various angles.
