The Spruce Budworm Information Session was held on May 1, 2025 and hosted by Keeping Maine’s Forests. The session focused on the history of spruce budworm in Maine, the importance of monitoring populations through yearly branch sampling, the insecticides and approach (early intervention strategy) used for additive mortality in areas with rising spruce budworm populations, and the aerial spray program that will be implemented by some timberland owners in Northern Maine this spring.
