Figure S1. Self-thinning curve estimated from Forest Inventory and Analysis data for beech-containing forest plots in the 15-state study area.
Figure S2. Left: Stand trajectories (with respect to the self-thinning curve) as a function of relative beech abundance for Forest Inventory and Analysis plots and beech bark disease status, for beech and sugar maple. Right: Regression slope estimates by quantile (τ), with 95% confidence intervals.
