Tree Felling is the process of cutting down a tree to harvest timber, provide space for growth or remove trees that pose a risk to public safety. It is a complex task that requires knowledge, skill and experience to perform safely. Choosing the right felling technique is critical to ensuring that a tree is felled in the correct direction and with minimal damage to other trees and the surrounding area.
There are several factors that affect the way a tree falls, including the wind direction, the slope of the ground and the presence of major obstacles in the area. It is important to identify these risks before beginning tree felling to avoid accidents and property damage. A qualified professional will assess the area and determine whether the work can be done safely.
Once the site has been cleared and an escape path established, it is time to start the felling process. First, a notch is cut in the trunk using the chainsaw. A notch is usually 1/5th of the trunk’s diameter, but can be larger or smaller depending on the location and conditions. The notch will create a hinge that controls the direction in which the tree falls. It is also important to cut the notch at an angle that is a natural extension of the fall line.
Before attempting to fell the tree, it is important to determine its lean and any areas of crown snow load (snow covered branches). To do this, move away from the tree and use a plumb line. If the limbs of the tree are pointing in the same direction as the trunk, it is best to fell the tree in this direction. However, if the tree is obviously leaning in one direction or heavily loaded with branches on one side, it will fall in that direction regardless of your efforts.
In addition, it is important to ensure that no one is within a safe working distance of the tree. If you are felling a large tree, it is recommended that you work with a partner to increase your safety and efficiency. Ideally, an assistant should be standing a few feet behind you watching for falling branches and letting you know when it is time to leave the felling zone. It is also a good idea to have your assistant wear a signal coloured jacket or vest, so that they can be easily identified by other workers and passers-by.
It is essential to check that the forestry area has no major obstacles in the vicinity of the felling site, such as overhead lines, roads and buildings. It is also a good idea to deploy warning signs if the felling site is located in an area that is crossed by traffic on a daily basis. It is also a good idea to plan the tree felling in advance by deciding the felling direction and clearing the surrounding area of any debris and potential obstacles.
