Eight other species, including chinkapin oak, Ohio buckeye, white ash, and hackberry, had lower importance values (Table 1).
Trees of secondary importance included chinkapin oak, Ohio buckeye, white ash, box-elder, and hackberry (importance values 33, 26, 18, 14, and 11, respectively).
Ten other species, including chinkapin oak, red oak, Ohio buckeye, and pawpaw, had lower importance values (Table 5).
In 1994, twenty years after the tornado, Transects 1 & 2 (the more damaged part of the valley) remained a sugar maple/slippery elm community with chinkapin oak, Ohio buckeye, basswood, and white ash of secondary importance (Table 7).
Chinkapin oak importance was due to its relative dominance.
A few larger-diameter stems of chinkapin oak contributed to its importance.
Ohio buckeye and chinkapin oak had lower importance values on this transect.
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%.
But all those states can draw hope from former club member Nebraska, which returned to the Register with the discovery of what has turned out to be the country's biggest-known dwarf chinkapin oak, in Richardson County, and a co-champion eastern cottonwood in Seward.
Other notable new champions include a 523-point co-champion live oak in Waycross, Georgia, with a crown spread of nearly 50 yards; a 420-point co-champion American elm in Shelby County, Tennessee (a fortunate find given that its co-champ has been diagnosed as dying from Dutch elm disease); and eight species that previously had no champion: holacantha (Holacantha emoryi), redherry juniper (Juniperus erythrocarpa), Nebraska's dwarf chinkapin oak Quercus prinoides), Mohr oak (Quercus mohriana), orange (Citrus sinensis), jumping-bean sapium (Sapium biloculare).
