Why is the use of spurs prohibited on living trees?

The use of spurs on living trees is prohibited primarily because they cause wounds and damage to the tree. When spurs penetrate the bark, they create openings that can lead to infection by pathogens, including fungi and bacteria. This can result in decay within the tree, disrupt its vascular system, and ultimately weaken its structure. Moreover, the wounds created by spurs do not heal as effectively as other types of tree injuries, making them particularly detrimental to the overall health of the tree.

Understanding the impact of spurs is vital for arborists and tree care professionals. They are designed for use on dead or disabled trees where the risk of harm is minimal. Using spurs on living trees compromises their health, which is contrary to the practices aimed at promoting tree preservation and care. This highlights the importance of using appropriate tools and methods that do not inflict unnecessary harm on living trees.
