What potential issue can arise if low codominant stems are allowed to develop on a tree trunk?

Allowing low codominant stems to develop on a tree trunk can lead to a variety of structural issues, one of which is that trunks can decay if stem removal is needed. Codominant stems create competing growth on the tree, which can lead to an improper distribution of weight and stress on the trunk. This imbalance may eventually require the removal of one or both stems to maintain the health and structural integrity of the tree.

When this removal occurs, it creates a cut surface that can be vulnerable to decay. If the cut is not made properly or if the tree is already stressed, this area may not heal effectively, leading to decay in the trunk, which can weaken the tree further. Additionally, the presence of multiple stems can create a scenario where the tree lacks a single dominant leader, making it more susceptible to storm damage and other environmental stresses.

In the context of tree management, it's crucial to monitor and manage codominant stems early on to prevent these decay-related issues and maintain the tree's overall health and safety.
