Assess the variation in within-season timing of measurements, using same plot design as in the National Forest Health Monitoring Program (NFHM). Initially part of a cooperative monitoring program with other states and Canada, since 2002 Vermont has measured these plots independently for internal use. NAMP is primarily an overstory/forest health monitoring program but they have collected regeneration data beginning in 1998.Forest Health Monitoring: North American Maple ProjectHalmanJoshuaJohnsonMichaelSimmonsTomWilmotSandraSchultzBarbaraPetersonFlorenceLackeyJayWellsRonLundLarsMeachamEmilyforest ecologylong term monitoringregenerationsugar mapleforest healthtree healthSummary of Cluster- and Transect-Level Data for NAMP1988-01-01Summarized data for permanently tagged trees that are evaluated annually for crown condition, injury to bole and crown, taphole closure, seed production, regeneration and early and late season defoliation.Annual measurement of sugar maple forest stands to determine tree condition, trends and possible causes of sugar maple decline.Z0068_NAMPPlotSummary2012VMC.68.335mySQLSandra Wilmot. 2017.
