Bark beetles, often seen as destructive pests, play a much more complex role in forest ecosystems than we typically imagine. These tiny insects bore into the bark of trees, feeding and laying their eggs, which can eventually weaken or kill the host tree. While their infestations can appear devastating, bark beetles have been shaping forests for centuries, influencing their structure, diversity, and renewal cycles. Their presence is a natural process that both challenges and sustains the balance of woodland environments. When bark beetles attack, they often target weakened or stressed trees, such as those suffering from drought, disease, or old age. By doing so, they act as natural regulators, clearing out less resilient trees and making room for younger, healthier growth. This selective removal helps ensure that forests do not become overcrowded, which can reduce competition for resources like sunlight, water, and nutrients. In this sense, bark beetles contribute to the natural t...
