Data were collected on seed production dynamics of long-lived plants, reproductive plant traits of those plant species, and weather variability for sites where those species live. Data include the coefficient of variation in seed production over time, the variation (coefficient of variation or standard deviation) in weather over years, and reproductive traits such as pollination mode and seed dispersal mechanism. Data series were distributed globally and encompass 920 data series containing 311 plant species. Data series are all 6 or more years in length.

We calculated estimates describing interannual variation in seed production for series of long-term seed or fruit production in 219 plant species. For each plant species, we compiled estimates of foliar nutrient concentrations as well as productivity and weather at the site of observation. Data was compiled in order to test whether interannual variation in seed production was greater in species with lower foliar nutrient concentrations or greater nutrient imbalances.

Data were compiled on the seed production of white spruce in order to assess the long-term trends in seed production over the past 60 years in North American boreal forests. Data on cone production was merged with annual weather, teleconnection indices such as ENSO, and historical fires in boreal forests.
Compiled 1086 datasets of plant seed production spanning 1900-2013 and from around the world were binned into 2-decade periods for which CV (coefficient of variation) of seed set was calculated. Skewness, dip test, mean, and kurtosis were calculated for the same periods.
