Maps of L2 Survey Results
The UMaine Spruce Budworm Lab at the University of Maine is currently supported by the Cooperative Forestry Research Unit (CFRU) program and the U.S. Forest Service. To predict SBW populations for the following year, tree branch samples are collected in the fall and submitted to the Spruce Budworm Lab. The Lab processes the branch samples and counts the overwintering stage of SBW, better known as an L2. L2 counts and models will be updated weekly as new samples are processed.
