Abstract

    The Forest Health Monitoring Program was established in 1991 as a joint effort between the Vermont Department of Forests, Parks and Recreation (FPR) and the Vermont Monitoring Cooperative (VMC) (as of March 2017 renamed to Forest Ecosystem Monitoring Cooperative (FEMC)) to monitor the condition of a range of tree species in Vermont. 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.
