A list of
bryophytes of the State Nature Monument “Gora Vaida” (“The Vaida Mountain”),
supplemented by a brief phytogeographic overview, is presented. It includes 57
species of hepatics and 138 of mosses. The flora is predominantly boreal with a
number of East Asiatic and arctic-alpine species. The mountain is formed by
limestone, which is rare in Sakhalin; so many species have here quite isolated
populations. Sauteria japonica (Shimizu et S. Hatt.) S. Hatt. is
recorded for the first time for Russia. Many northern species, e.g. Arnellia
fennica, Eocalypogeia schusteriana, Tomentypnum nitens, Scorpidium cossonii, Catoscopium nigritum,
Meesia uliginosa, etc. were found new to Sakhalin, occurring at ridge top
in mossy tundra-like communities.
