“a” = number of tree species common to sites A and B; “b” = number of tree species recorded only in the site A; “c” = number of tree species recorded only in site B, “N”: total number of individuals of all the species; “n”: total number of individuals of the species; Shannon diversity index (H) = where pi is the proportion of individuals found in the ith species; SSI = Sorensen similarity index, H = Shannon diversity index; SD = stump density; EF = expansion factor (3.4 for tropical forest); LD = live tree density. |
