2 Forests and natural processes

2.2 Bark beetle outbreaks

Bark beetle outbreaks are natural disturbances that play a significant role in forest dynamics. These insects help to create gaps in the forest canopy, allowing light to reach the forest floor and promoting the growth of diverse plant species.

While bark beetle outbreaks can be devastating in the short term, they contribute to long-term forest health and resilience. In managed forests, efforts to control bark beetle populations can disrupt these natural processes and reduce habitat diversity.
