This study examines the factors affecting the lack of success in regeneration of natural populations of European yew. Among the numerous local factors that can be important in the existing populations, the lack of reproductive success is most probably due primarily to shading, combined with low temperatures in winter, impact of herbivores, and limitations associated with dioecy. In many cases it seems necessary to apply active protection measures supporting this species within its natural range of distribution. The major recommended actions include fencing of yew populations and thinning of the canopy.
