As of Aug 31 2020 there are 10,305,225 seeds recovered from seed traps and 453,722,912 from crop counts of cones, fruits, pods, and seeds. There are 3,666,188 observed trees, 11,189,240 tree-years, and 1364 species from 132 families. The network includes 2611 plots and iNat hectares (iNat observations aggregated by hectare).

Trees are observed outside their native ranges to increase the climate/habitat space for fecundity responses. Species  in this table show the region where they are native or naturalized followed by columns for tree-years where they were observed. The native/naturalized column and column names include continents and/or ‘NAM-east’ (eastern North Amer), ‘NAM-west’ (western N America), and ‘SAM, CAM’ (South and Central America, Caribbean Islands).

We are continually adding observations though monitoring of inventory plots and opportunistic sampling using iNaturalist. For model fitting we include species observed in multiple years with at least 10 individuals.
