Plot design follows the structure set by the National Forest Health Monitoring Program with additional metrics added to reflect improvements in monitoring technologies and additions to monitoring objectives.Forest Health Monitoring: Mt Mansfield, Lye Brook Wilderness Area, and Ranch ValleyStandard tree size measurements and damage assessments on plots in Mt.
