Why is the mountain pine beetle a problem?
Low or endemic beetle populations cannot overcome the defences of healthy trees and attack suppressed, weak or dying trees. Suppressed and weak trees are usually poor-quality hosts for the beetles because they may already have been attacked by competing insects and the thin inner bark layer is a poor habitat.
Why are mountain pine beetles bad?
