Effects of time since fire (TSF) and tree size classes on seed viability, seed production, and cone production. a Model estimates of seed viability (n = 32) from the highest-ranking intercept-only model, shown in relation to TSF. b Model estimates of seed count per cone as a function of tree size class (n = 443). The ‘small-tree’ size class was not represented by the collected cones, which were sampled from the ten closest trees to plot center. c Model estimates of cone count per tree as a function of tree size class (n = 3225). a–c Boxes and arrows show the coefficient estimate ± 95% confidence interval, and gray symbols show the data points. d The relationship between tree density and plot-mean cones per tree. Colors indicate TSF, with yellow representing the most recently burned plots and dark purple representing the oldest post-fire plots. The black line shows the estimated linear relationship between plot-level tree density and cones per tree (values log10-transformed)
