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.Vermont Forest Health MonitoringJohnsonMichaelSimmonsTomWilmotSandraPetersonFlorenceLackeyJayWellsRonGreenoughBradLundLarsBartonBerniePontiusJenniferKosibaAlexandraDuncanJamesGudex-CrossDavidMurrayHelenaWilliardKatlynSandbachChristineTruongJohnCarrKirstiGurvichDianaRossellBeccaDraytonCarolineRomakerElizabethHammKelseyPerrinMikeUpdikeSawyerRotellaStephenWardDanielleRobertson Josephine DesideraggioGenelong term monitoringforest healthcontinuous forest inventory forest regenerationforest compositionforest health monitoringForest Health Monitoring: Mt Mansfield, Lye Brook Wilderness Area, and Ranch Valley1992-01-012015-12-31Standard tree size measurements and damage assessments on plots in Mt.
