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 productionmastmaineLitter Traps1983-05-011990-12-31CSV file, 1983-1990 seed collection data from 40 litter traps in the research area.Collect seed fall to determine seed abundance and litter fall to biomass production.Z1217_2440_7CD7AYVMC.1217.2440mySQLHolt Research Forest, University of Maine (2019) LitterTraps.
