| Abstract: | Frequency data for 21 species of corticolous macrolichens in 14 upland forest stands were analyzed in relation to a number of environmental variables, using correlation and ordination techniques. Results indicate the predominance of macroclimate—especially precipitation—in determining the frequency behavior of bark lichens within the limited area of this study. Less important, though significant, factors include the frequency of preferred host-tree species, the age structure, and tree-species composition of stands. |
