Distribution, protection and restoration of Taxus baccata L. in Ukraine

Abstract

English yew is one of the most endangered species in Europe. Due to the specificity of this species, its natural regeneration is quite difficult. The aim of the study was to present the current situation of distribution, protection and restoration of the species in Ukraine. The study presents some characteristics of largest natural and artificial yew populations in the country and their protection. In situ and ex situ yew populations are quite different, in terms of bioclimatic conditions what does not affect to the growth characteristics of the populations. In addition, the activities related to the natural and artificial renaturalisation of the yew were analysed. Thus, tending of tree stands, where the natural regeneration of yew was inventoried can be recommended but it should be planned very individually regard ing requirements of the site. The introduction of yew seedlings in the conditions of the managed forest is very dif ficult. Despite the complication of obtaining planting material and high cost, it is important measure to preserve the species. In Ukraine are successful examples of the seed transfer of yew populations by about 450 km in North-East direction (Carpathian yew population) and 700 km in North direction (Crimean yew population). It is an evidence of high ecological plasticity of the species. Moreover, some recommendations that could be useful for increasing the popularization of this species throughout the country were given in conclusions. The wider use of yew in public areas across the country due to unique value of species and more convenient protection of young seedlings. It is worth to continue the inventory of yew locations at the national level and study the possibilities to use as local sources to conservation of this species throughout the country.
