Changes in Forest Composition on Big Ridge Natural Study Area, Union County, Tennessee

ABSTRACT
In 1936 a total of 145 plots were established and the trees recorded by species and diameter. The same plots were re-inventoried in 1967 and changes which had taken place were analyzed. The death of American chestnut during this period and its replacement by oaks and Virginia pine constitute the most dramatic changes. Important changes in density, basal area and importance value occurred in several other taxa.
