For the last column, size classes sharing similar letters are not different at P < 0.05 (ANOVA, F 5,291 = 5.42, P < 0.0001). CK = Cook Inlet, CR = Copper River, RM = Ray Mountains, TKL = Tanana Kuskokwim Lowlands, NOM = North Ogilvie Mountains, YTU = Yukon Tanana Uplands. The absence of size classes within ecoregions is because no trees were found within that size class, or that none of the trees within that size class were infected.
