Plans are being finalized to continue assessment of annual mortality due to 
mountain pine beetle during the current field season. Work will be conducted 
in infested lodgepole pine forests in Montana, and in the Black Hills test 
site where refinements in sampling design are being evaluated to improve 
reliability of estimates.
