They form two 600 m long strips across the study area, and cover a total of 1200 m2. Plots are numbered from 1 to 600 and listed as being north (quadrats 3E1 to 8E2) or south (quadrats 3I3 to 8I4). A tree seedling count is conducted on the 1m2 plots to provide information on the regeneration of the forest. All S-1 plots were measured in the 1986 field season; every fifth plot (1,6,11, etc.) is measured each subsequent year.Holt Research Forest Tree Seedling Counts, 1m2 PlotsCooperClarkeWithamJackFrenchKellyMurrayPaulinaseedling establishmentseedlingsmaineforest regenerationAnnual Seedling Counts 1986 - 20191986-05-01CSV file; annual tree seedling counts by species and height class, 1m2 plots, 1986-present.Z1218_2441_T7PXFPVMC.1218.2441mySQLHolt Research Forest, University of Maine (2019) s1Seedling.
