Rare mosses of the Kondinskie lakes natural park named after L. F. Stashkevich

The moss flora of the Kondinskie Lakes Natural Park named after L.F. Stashkevich (Khanty-Mansi Autonomous Okrug - Yugra, Russia) currently in-cludes 114 species. Fifty-four species (47.4%) are rare for the natural park, of which eleven species, such as Dichelyma capillaceum, Dicranum septen-trionale, Sphagnum annulatum, S. mirum, S. subfulvum, S. tenellum, are rare for the Khanty-Mansi Autonomous Okrug and Western Siberia. The phytocenotic association and the frequency of oc-currence of the studied species was analyzed. The paper discusses the reasons for the high proportion of rare mosses in the park’s brioflora and the fea-tures of their distribution over the territory of the park.
