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.Tree Health and Physiology MeasurementsMeasurements of a wide range of tree characteristics, including height, diameter, crown condition, health indicators and
