Abstract

In order to determine the distribution of common yew (Taxus baccata L.) and to assess biodiversity of woody vegetations of its sites, a 0.5 ha sampling plot was selectively sampled in each site. The type of woody species and the number of individuals for each species were recorded in each plot. The collected data from each site was then camputed. A divers programm was used for assessment of biodiversity indices (Simpson's index, Shannon- Weiner function and Brillouin's index) for each site. The, richness indices of Margalef and Menhinick for each site were also calculated. The results showed that the sites number 1,2,4 and 8 had the highest species diversity while the'sites 9,13 and 15 had the lowest value in diversity.
