   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 ...

   For example, tree with 5 inches at DBH has the unit cost of $70 while tree with 15 inches at DBH has the unit cost of $12. As the cost of feller buncher is high, only large tree volume can produce more profit to cover the high average cost. In terms of stump height, lower stump height can maximise the use of natural resources and prevent wood ...

   Cut-to-length logging is the process of felling, delimbing, bucking, and sorting (pulpwood, sawlog, etc.) at the stump area, leaving limbs and tops in the forest. Mechanical harvesters fell the tree, delimb, and buck it, and place the resulting logs in bunks to be brought to the landing by a skidder or forwarder. This method is routinely ...

6. Heli-logging - Wikipedia

   en.wikipedia.org/wiki/Heli-logging

   Heli-logging is also known as standing stem harvesting, which is based on individual tree selection (ITS). [6] The selection process is done by engineers and surveyors. The trees are selected based on demand for specific types and grades. Before the selection process is complete, the selected trees are bored to check their reliability.

7. Tree stump - Wikipedia

   Tree stump, about 37 years after falling. After a tree has been cut and has fallen, the stump or tree stump is usually a small remaining portion of the trunk with the roots still in the ground. Stumps may show the age-defining rings of a tree. The study of these rings is known as dendrochronology. Stump sculpture by German artist Eberhard Bosslet
