How can insect infestations affect a tree's risk?

Insect infestations can significantly affect a tree's risk by weakening it and making it more susceptible to diseases. When insects invade a tree, they can damage key elements such as the bark, leaves, or even the roots. This damage disrupts the tree's ability to transport nutrients and water effectively, which can lead to a decline in overall health.

As the tree becomes weaker and its defenses are compromised, it may struggle to fend off pathogens and other environmental stresses. This increased vulnerability can ultimately lead to a greater risk of failure, especially in storms or high winds, as the structural integrity of the tree is diminished. Therefore, understanding the role of insect infestations is crucial in assessing a tree’s risk level effectively.
