Forest pests are organisms, such as insects, fungi, and diseases, that can harm trees and other plants in forest ecosystems. These pests can weaken trees, making them more susceptible to other threats, and can lead to significant economic losses in timber production. Common examples include the bark beetle, which burrows into tree bark, and oak wilt, a fungal disease that affects oak trees. Managing forest pests is crucial for maintaining healthy forests. Strategies include monitoring pest populations, using biological control methods, and applying pesticides when necessary. Healthy forests provide essential benefits, such as clean air, wildlife habitat, and recreational opportunities for people.
