A good rule of thumb for all felling scenarios is to make the depth of the face cut or undercut, which is your directional angles notch face the way you want the tree to fall, roughly equal to 1/3 the diameter of the tree. [5] Additionally, one should leave about 10% for your holding wood or hinge wood to direct the tree on its way to the ...
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 ...
The undercut or notch cut is the guiding or aiming slot for the tree and is a V-shaped notch placed on the side of the tree in the direction of intended fall. [4] The back cut or felling cut is made on the opposite side of the tree of the undercut and is cut through the base of the tree severing the “hinge” holding the tree up. [4]
A felled and delimbed tree is cut into logs of standard sizes, a process called bucking. A logger who specialises in this job is a buck sawyer. Bucking may be done in a variety of ways depending on the logging operation. Trees that have been previously felled and moved to a landing with a log skidder are spread out for processing. While many of ...

Clearcutting contrasts with selective cutting, such as high grading, in which only commercially valuable trees are harvested, leaving all others. This practice can reduce the genetic viability of the forest over time, resulting in poorer or less vigorous offspring in the stand.
