Bark Beetles Part 3 Bark beetles in Douglas-fir and true fir

Promoting tree health and resilience is the best way to prevent attacks from forest insect pests such as bark beetles but early diagnosis of bark beetle attack can aid in mitigation of damage. Planting appropriate tree species in suitable sites and reducing density and competition within the stand goes a long way to ensure trees are healthy enough to resist or tolerate pests. This video covers diagnosis of bark beetles specific to Douglas-fir and true fir and is part of a 3-part bark beetle series that includes an introduction to diagnosis of bark beetles and diagnosis of bark beetles specific to pine. Other videos in the Oregon forest insect pest series include sections on woodborers, defoliators, and sap-sucking insects, as well as abiotic stressors.
