Advantages & disadvantages [ edit ] Shelterwood cutting is ideal for species that are long-lived, have seedlings that would naturally tend to start under partial shade or full shade, [ 11 ] and have seeds that are not easily dispersible.
a harvesting method Clearcutting method – a method for regenerating an even-aged community by removing all the mature trees Clearcutting system – a silvicultural system incorporating the clearcutting method to remove (clear) the mature community over a considerable area at one time [ 13 ]
Even-aged forest management is the harvesting system of choice in many parts of the world because it is often considered to be the only method that is economically viable. Forestry operations have extremely high variable costs- per hour expenses for harvesting equipment and per kilometer expenses for log transportation compose a very large ...
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 ...
Logging frequently has negative impacts. The harvesting procedure itself may be illegal, including the use of corrupt means to gain access to forests; extraction without permission or from a protected area; the cutting of protected species; or the extraction of timber in excess of agreed limits. [4] It may involve the so-called "timber mafia".
Salvage logging is the practice of logging trees in forest areas that have been damaged by wildfire, flood, severe wind, disease, insect infestation, or other natural disturbance in order to recover economic value that would otherwise be lost.
Silvicultural regeneration methods combine both the harvest of the timber on the stand and re-establishment of the forest. The proper practice of sustainable forestry [ 119 ] should mitigate the potential negative impacts, but all harvest methods will have some impacts on the land and residual stand. [ 120 ]
Selection cutting in California, May 1972 The results of selective cutting of Ponderosa Pine. Selection cutting, also known as selection system, is the silvicultural practice of harvesting trees in a way that moves a forest stand towards an uneven-aged or all-aged condition, or 'structure'.
