This study was conducted to illustrate how to estimate true species diversity using upper confidence limit value of Pla unbiased estimator (H ̂_ ^e+1,96σ_H^* ) and Shannon entropy-based bias-corrected diversity (SCD) measures (i.e., Jackknife index

A new method was proposed to estimate ecosystem naturalness. Three species-plot (S Χ A) datasets were used. Those data sets belong to Sultan mountain sub-district (BS) (60 Χ 96) Dedegül mountain sub-district (BD) (89 Χ 119) and, Beyşehir Watersh

An ecosystem diversity index was proposed by the present study. The proposed index (H_wd ) considers not only the species compositions of the meta communities and their land cover areas but also heterogeneities of their geographical distributions. H_
