Abstract
According to the system of A. A. Grossheim the geographical analysis of the flora of broad-leaved and coniferous forests with Taxus baccata in Dagestan is given. In four forest massifs of the Predgorny (Buinaksky district – 980 m a.s.l., Kaytagsky district – 800 m a.s.l., Kazbekovsky district – 1050 m a.s.l.) and Inner Mountain (Khunzakhsky district – 1540 m a.s.l.) Dagestan revealed 203 species of vascular plants in the period of 2010–2018. The quantitative ratio of the main geographical elements was estimated. In total 12 classes of geoelements belonging to 5 types have been identified: ancient (tertiary) forest, boreal, steppe, xerophilic, Caucasian. It is shown that most of the species belong to the boreal type (61,1–71,4%) and the Palearctic and European classes, represented in the forest zone of the Northern Hemisphere. The participation of Caucasian species is significant (20%), which indicates the relative originality and ancient of the forests of Dagestan with the participation of European yew.
