Table 1 Average circumferences over bark (CBH) of the crown classes and site indexes, measured in 1989. ANOVA analysis revealed no significant differences in the average CBH of a given crown class between plots or in the total stand average CBH between plots. Within plots, crown classes generally differed in mean circumferences, except for values with the same letter (pairwise t tests at the 5 % probability level). Site index is the top height at the age of 25 years. Values in parenthesis are the number of trees
