Summary: | In our forest science and forest operations, the tree species richness and
diversity of woody species in forest stands are most often evaluated based on
the total number of tree species, which is a methodologically partly
inadequate approach. For this reason, the quantification and the evaluation
of diversity of woody species in mixed forests of beech with valuable
broadleaves in the area of the National Park ?Djerdap? were analyzed by five
different indices of tree species richness: number of species (S index), two
indices of the species richness (R1 and R2), expected number of species in
the sample with equal numbers of trees (E(S84)), and expected number of
species in the sample with equal areas (E(S0,25ha)). The results showed that
the level of woody species diversity in forest stands depended on the applied
index characterizing the tree species richness. It was concluded that the
tree species richness and diversity were the highest in the stands of
ecological unit B (E(S84)=8.6 species) and in the stands of ecological unit G
(E(S0,25ha)=9.4 species), and they were the lowest in the stands of
ecological unit V (E(S84)=5.8 species, E(S0,25ha)=5.5 species).
