Since 1988 we have used 0.042m2 traps (n = 264 traps, collections once per year in May before red maple seed fall. Litter collection was dropped because the volume was too great to effectively sort and measure. Seed collection was maintained because seed production relates well to tree recruitment and small mammal abundance.Holt Research Forest Annual Tree Seed CollectionCooperClarkeWithamJackFrenchKellyMurrayPaulinaseed productionmastmaineseedTraps-S11988-05-01CSV file, 1988-2013 collection data from 120 seed traps along S1 survey lines; located west to east at 10m intervals.Determine seed production of the forest close to sample sites for tree seedlings.Z1217_2434_SMZWOHVMC.1217.2434mySQLHolt Research Forest, University of Maine (2019) seedTrapsS1.
