Figure 1 O'Malley (2026): Yields varied substantially across the LegacyNet sites.
(A) The locations of the 26 LegacyNet sites, indicated by inverted yellow triangles (see data S1 for the site location details and ID codes). (B) The yield per growing season (t ha−1) based on plot-level measurements for each site are shown in boxplots that are grouped by mixtures (blue; 29 plots per site) and monocultures (gray; 18 plots per site), at the moderate nitrogen fertilizer level. The average yield of the six-species equiproportional mixture plots (three plots per site) is shown as a magenta triangle. The average yield of the monoculture plots from each functional group is highlighted with a circle (green for grass, orange for legume, and light blue for herb; six monoculture plots per functional group per site). The average yield of the high N grass monoculture (five plots per site) is shown by a red horizontal line. Sites are arranged on the x axis in order of decreasing median yield. The center line represents the median, box limits are upper and lower quartiles, and whiskers extend to the minimum and maximum of nonoutlier values.
