What is a potential hazard posed by large-branch removal from decurrent trees?

The potential hazard posed by large-branch removal from decurrent trees is the formation of codominant stems. When a large branch is removed, particularly if the cut is not made correctly, it can disrupt the tree's structural integrity. This disruption may result in the development of two or more stems that grow closely together, known as codominant stems.

Codominant stems can be problematic because they often lack a strong central leader; instead, they may compete for dominance, leading to weak branch junctions. These weak points can increase the risk of failure during heavy winds or due to the weight of the branches as they grow. Proper pruning techniques are essential to minimize this risk, ensuring that any cuts made promote the development of a single leader and a more stable structure.

In contrast, while increased light exposure may occur after removing branches, it does not inherently pose a hazard. Similarly, while decay in the trunk can be a concern, it is more a result of improper cutting or disease than a direct hazard from the removal process itself. Lastly, reduced privacy is typically not a concern when considering the health and safety of the tree and surrounding area.
