Abstract

This dataset is from the manuscript Identifying tree genotypes for high-performance mixed forests. We investigated whether tree genetic identity in eight test species affected individual growth (i.e., cumulative biomass) over time in experimental forest stands, across mixtures providing a gradient of species richness. First, we used the ten-year (2012–2021) biomass data from the center of the plots in the experiment, where 3,106 trees had been measured continuously over time, to test the relative contributions of variation in species and genetic identity to variation in tree growth over time. (Data 1 for Figure 2). Second, using biomass data for the two years 2012 and 2021 from all 13,519 trees surviving until 2021, we tested how genetic identity affected tree growth across the tree species richness gradient (Data 2 for Figure 3). Third, using data of the 13,519 trees from the two years 2012 and 2021 again, we tested if the relative contribution of genetic identity increased with species richness, as predicted because of reduced intraspecific competition (Data 3 for Figure 4).
