“…3. Top five diversity indicators with the highest correlation: with individual qualities of timber production (a), with individual age categories (b) with the study area QTP -indicator of the quality of timber production, QTP1 -best-quality timber, QTP2, QTP3 -sawn timber of higher and lower quality, QTP4 -pulp and fuel wood, black circle -percentage of significant correlations of the diversity indicator with the quality of timber production, grey bar -average value of correlation coefficient R xy calculated from significant correlations of a particular diversity indicator, white rectangle -95% confidence interval of the average value of correlation coefficient R xy calculated from all correlations derived for a particular diversity indicator, black dagger -average value of correlation coefficient R xy calculated from all correlations derived for a particular diversity indicator, black diamond -structural indicator of diversity, BC1_SP_Rr -BC1 index of similarity (Bray, Curtis 1957) between the trees with diameter below 7 cm and the trees with diameter above 7 cm, while the species composition was derived from the growth area, BC2_SP_Hpa -BC2 index of similarity (Bray, Curtis 1957) between the trees with diameter below 7 cm and the trees with diameter above 7 cm calculated from the average tree heights of species, BP_ST_Ha -BP index of species evenness (Berger, Parker 1970) calculated from the sum of tree heights of trees with diameter above 7 cm, BUB_SP_Rr -BUB index of similarity (Baroni-Urbani, Buser 1976) between the trees with diameter below 7 cm and the trees with diameter above 7 cm, while the species composition was derived from the growth area, D_ST_Na -D index of species evenness (McIntosh 1967) of trees with diameter above 7 cm, DF1_SP_Hpa -DF1 index of similarity (Canberra distance) (Lance, Williams 1966) between the trees with diameter below 7 cm and the trees with diameter above 7 cm calculated from the average tree heights of species, E1_SP_Hr -E1 index of species evenness (Pielou 1975(Pielou , 1977 of all trees, while the species composition was derived from the sum of tree heights, E1_ST_Rr -E1 index of species evenness (Pielou 1975(Pielou , 1977 of trees with diameter above 7 cm, while the species composition was derived from the growth area, E3_SP_Hr -E3 index of species evenness (Heip 1974) of all trees, while the species composition was derived from the sum of tree heights, E3_ST_Hr -E3 index of species evenness (Heip 1974) of trees with diameter above 7 cm, while the species composition was derived from the sum of tree heights, E3_ST_Rr -E3 index of species evenness (Heip 1974) of trees with diameter above 7 cm, while the species composition was derived from the growth area, E5_SP_Hr -E5 index of species evenness (Hill 1973) of all trees, while the species composition was derived from the sum of tree heights, E5_ST_Hr -E5 index of species evenness (Hill 1973) of trees with diameter above 7 cm, while the species composition was derived from the sum of tree heights, ED1_SP_Ha …”
