Box plots of (A) canker incidence (% aspen trees infected) by ecoregion, and (B) % of trees infected with canker that are dead. Ecoregions sharing different letters are significantly different at P < 0.05 (ANOVA model, F 5,82 = 5.10, P < 0.001). Means ± 1 STD error are listed across the bottom of the graph.
