Genetic diversity and geographic distribution for 403 geo-referenced observations of ex situ medicinal plants collection data including 13 species, from twelve counties of Albania was investigated, using grids of 10 x 10 km cells to assess the number of observations per species and per district, the area of occupancy, the diversity indices and richness estimators. Geospatial analysis detects areas of high (alpha) diversity. Combination of study results for Simpson index, Dominance, Shannon-Weiner, Margalef, Brillouin, species richness and evenness, Equitability, Menhinick, Berger-Parker, and Fisher alpha diversity index show that areas of Tirana, Berat, Shkodra, Lezha, Vlora, and Kukesi counties were richer and more even than other areas. Cluster analysis on correlation matrix of diversity indices results shows presence of high similarities among Berat and Vlora counties, Tirana and Shkodra, Dibra and Lezha counties (similarity range from 64% to 80%). Presence of high species diversity in Tirana, Lezha, Berat, Shkodra, Vlora, and Kukesi counties suggests presence of a greater number species and more relative stable ecosystems, where more ecological niches are available, and environmental changes were less likely to be damaging to the ecosystem as a whole.
