As growing spruce budworm populations continue to fluctuate in Maine, the Maine Forest Service, University of Maine Cooperative Forestry Research Unit (CFRU), and our cooperator network are tracking populations carefully in anticipation of an approaching outbreak.

A comprehensive spruce budworm (SBW) monitoring program requires a multi-pronged approach. It relies on using methods such as pheromone trapping, light trapping, overwintering L2 larval sampling, and both ground and aerial survey. At the core of the Maine Forest Service (MFS) monitoring program lies the extensive pheromone trap network throughout western and northern Maine's spruce-fir forests. A permanent pheromone trap network was first established …

This past year has been a challenging time for the CFRU as we learned to cope and work during a global pandemic. More isolation became the norm and video conferences replaced the in-person meetings we are accustomed to. Despite these challenges, the CFRU remained active thanks to the dedication of our Interim Program Leader, Aaron Weiskittel, and his support staff, Leslee Canty-Noyes and Meg Fergusson. Their efforts to adapt to changing circumstances ensured that research advanced, meetings successfully carried on, spruce budworm L2 sampling was conducted, MASN sites were established, and the daily administrative functions of the CFRU continued.

The Maine Spruce Budworm Task Force was formed in summer 2013 by the University of Maine’s Cooperative Forestry Research Unit (CFRU), Maine Forest Service (MFS), and Maine Forest Products Council (MFPC) to begin preparing for the next outbreak of the eastern spruce budworm.

The last SBW outbreak during the 1970s–80s grew quickly, killed millions of acres of spruce-fir stands, and cost the region’s economy many hundreds of millions of dollars. Although it is not possible to predict exactly when defoliation of balsam fir and spruce will begin, how severe the next outbreak will eventually become, or how long it will …
