Tree Felling Basics

Tree Felling is an intricate process that requires a deep understanding of trees and a commitment to safety. This complex forestry technique involves the careful and deliberate cutting down of a tree using a variety of specialized tools, such as an axe for chopping and a chainsaw for slicing. Tree felling is an essential part of many forestry and arboricultural practices, including timber harvesting, land clearing, and mitigating hazards posed by a dead or damaged tree.

The first step in a felling operation is to create a large notch, known as an undercut, on the side of the tree that faces the direction you want the tree to fall. The two sawyers who performed the demo used double-bit axes and balanced on wood springboards stuck into slots chopped into the sides of the stump, alternating their strikes to chop out a sizable notch. The undercut weakens the base of the tree and guides its direction of fall, reducing the risk of injury or damage to structures or property.

Once the undercut is created, a back cut is made on the opposite side of the tree, a few inches above the notch cut. The back cut completes the aiming or guiding slot, further directing the direction of fall and minimizing potential damage or injuries to surrounding properties or structures. A modified version of the undercut, called an open-faced undercut, is increasingly popular in many regions because it’s easier to make and provides additional guidance for the saw chain.

Before making any felling cuts, the sawyer should examine the site and assess any obstacles or risks that may affect the operation. A good starting point is to determine the tree’s natural direction of fall by studying its shape and assessing any crown snow-load (snow-covered branches). If unsure, step away from the tree and check with a plumb bob to get a more accurate assessment.

Finally, the sawyer should make sure they have a safe escape route to retreat from the worksite if something goes wrong. This should be a clear path of at least 45 degrees away from the intended falling direction, free from any debris that might block or hinder the escape route.

As you can see, the felling of a tree is a complex process that can be dangerous and time-consuming. It’s best to leave it to a professional who has the training and equipment necessary to do the job safely and correctly. If you’re considering taking on the challenge yourself, be sure to follow proper working techniques and don’t cut into any power lines in close proximity to the fallen tree. Also, make sure to invest in the right equipment, such as plastic wedges and a STIHL axe designed for felling, to maximize efficiency and minimize risk.
