American basswood, black maple and sycamore were of secondary importance in the more damaged (northern) part of the valley, while black walnut, white ash, northern red oak, and box-elder were of secondary importance in the less damaged (southern) portion of the valley.
American basswood, redbud and sycamore were of secondary importance (importance values 36, 23 and 22, respectively).
Nine other species, including red oak, black walnut, and American basswood, bad lower importance values (Table 3).
American basswood, chinkapin oak, redbud, and Ohio buckeye were of secondary importance (importance values 35, 20, 19, and 13, respectively).
Eight other species, including hackberry, red oak, black walnut, and American basswood, had lower importance values (Table 4).
Over the 5 years of this study sugar maple, slippery elm, chinkapin oak, Ohio buckeye, American basswood, and white ash keep the same descending order of importance although the importance value of sugar maple increased about 15%.
