Thema of the thesis is to analyse actual state and predict future application of english yew (Taxus baccata L.) in forest sites at chosen parts of PLA Moravský kras. Structure of parent stand and natural regeneration is analyzed on locations of interest Habrůvecká tůň, Lažánky, Sloup and Macocha. There was measured height, dbh, height of the crown, projection of the crown and space situations were drawned for mature individuals. In case of natural regeneration every individual was measured for height, distance from assumed parent tree, age and damage by game. At locations of interest were analysed 82 mature individuals. Height ranges from 1,7 to 13,4 m and dbh ranges from 4,1 to 33,7 cm. Natural regeneration containing 260 individuals was found near 35 mature yews and 58% was younger than 5 years. Damage by browsing was observed at 51 individuals, respectively 19,6 % of population. Mostly, trees older than 5 years are damaged. Damage is often repetitive. Only two individuals from natural regeneration are higher than 1m. From research is apparent negative influence of game on natural regeneration. Future of yew population in PLA Moravský Kras is conditioned to elimination of negative influence of game, which can be achieved by lowering numbers of game or suitable protection of trees.
