Numerical indices of diversity, in their entirety, do not provide a complete description of distribution and richness of species. Therefore, parametric indices should be also considered in studying of plant communities. In this regard, the indices of species richness, evenness and diversity related to the ecological sites of Cher mountainous rangelands of Urmia were calculated. The diversity pr...
