Plant Community of Pine Forests (Pinus kochiana, Pinaceae) of Dagestan.

The plant community of Dagestan pine forests, comprising 590 vascular plants species, was examined based on materials from field studies performed from 2012 to 2019. Taxonomic, biomorphological, florocoenotic, and geographical characteristics of the plant community showed its boreal and Mediterranean nature. Mesotrophic and eutrophic plants predominated in terms of soil fertility and mesophytes and mesoxerophytes, in terms of soil water availability. Species of different altitudinal belts, including forest, meadow, and mountain-steppe belts, were observed in the plant community of pine forests. The plant community included 22 species listed in the Red Books of the Russian Federation and the Republic of Dagestan, 82 relict species, and 76 endemics.
