Traits such as live crown ratio and understory stem density are often used subjectively as a guide to grouping tree species into shade tolerance classes. The accuracy of this approach was tested on nine species in an upland oak forest by comparing a tolerance index based on measurements of live crown ratio and understory stem density with observed survival and growth rates of suppressed trees obtained from 19-year permanent plot records. A high correlation (r = 0.93) was found between predicted and observed tolerance indices. The observed tolerance of several species differs from traditional classifications but was correctly predicted by the tolerance index.
