What is a "bark beetle"?

A bark beetle is a type of small beetle that primarily feeds on the inner bark of trees. These beetles are known for their ability to burrow into the bark, creating intricate tunnels and galleries. They play a significant role in forest ecosystems by decomposing dead or weakened trees. However, certain species of bark beetles can become destructive pests when they attack healthy trees, especially during outbreaks or when trees are stressed. The bark beetle infestation can lead to tree mortality, impacting forest health and timber industries. Effective management techniques, such as monitoring, tree removal, and the use of pheromone-based traps, are implemented to mitigate the damage caused by bark beetles and protect forest resources.
