The Occurrence of Quercus cerris in Covasna County

Abstract

The aim of this study is to describe the site and vegetation conditions of the populations of Turkey oak (Quercus cerris L.) discovered in the southeastern Transylvania, in order to find indices of species origin. Four sites, isolated from each other, were mapped and characterized through phytosociological releves. The isolation from the known area of Turkey oak and some practices in oak regeneration suggest the artificial origin of the species. Hence, the naturalness could be inferred from the floristic composition and coincidence of sites. The results are important for the knowledge of species ecology and vegetation description of the area.
