Abstract
The article presents new data on the vegetation of the island of Urup (Kuril Islands) obtained during the research of the authors in 2019 and 2021. The characteristics of the main forest communities (Erman’s birch forests, willow forests and Pinus pumila thickets), as well as rock and mire vegetation and vegetation of disturbed habitats, are given. The ecological-phytocenotic classification of the studied communities has been refined or carried out for the first time, the tables of geobotanical descriptions for a number of associations are given. Patterns of vegetation distribution in river valleys are considered. It is shown that in the northern part of the island, in the vegetation cover of the Pacific side, the role of mires and shrub communities increases in comparison with the Okhotsk Sea side. The description of soils is given in connection with the plant communities formed on them. The reasons of the revealed regularities are discussed, in particular, the influence of the relief, cold oceanic winds and fogs on the vegetation cover of the island.
