What technique can be used to mitigate leaners in tree felling?

The technique used to mitigate leaners in tree felling is specifically the boring backcut. This method is particularly effective for trees that are leaning in a direction that poses a risk during felling. A leaning tree can create complex challenges, as it may fall unpredictably or in the desired direction if not handled properly.

The boring backcut involves making a cut into the side of the tree opposite to the direction of the lean. This allows the operator to create a hinge that can better control the tree’s fall. By starting the cut on the opposite side, the feller can assess the lean and adjust the cut's angle to effectively guide the tree’s fall. This method minimizes the risk associated with the tree's lean and enhances safety for both the operator and the surrounding area.

Using other techniques like a standard backcut may not offer the same control and safety when dealing with a leaning tree. While hinge cuts and chunking are valuable techniques in various scenarios, they do not specifically address the complexities presented by leaners as effectively as the boring backcut does.
