The Maine Forest Service and UMaine’s Cooperative Forestry Research Unit continues to work together to gather L2 sampling data. This is a coordinated effort between northern Maine landowners and managers, the MFS, and the CFRU. See our most recent map of L2 survey results and the FAQ on L2 sampling data for more information.

Branch samples collected from plots throughout Maine’s working forest in December 2016 being analyzed for spruce budworm stage 2 larvae (SBW L2) by Rob Johns and Emily Owens of the Canadian Forest Service. Branches are chopped and washed in the buckets, then residues are transferred to gridded filter paper discs where the SBW L2 are counted. The counting process provides information on SBW population trends.
