The exploration of the area near Ayan Settlement and adjacent part of Dzhugdzhur Range on the Western coast of the Sea of Okhotsk revealed 164 species and 1 variety of mosses; their annotated list is provided. The cold and humid climate restricts the occurrence of the East Asian species that are more numerous in a few hundred kilometers to the south, and xerophytic plants that are characteristic to continental areas, at less than 300 km from the seacoast. Species with the North Pacific distribution are well represented in the area: Coscinodon yukonensis, Trachycystis ussuriensis, Myuroclada maximowiczii, Echinophyllum sachalinense, Sciuro-hypnum uncinifolium, Bartramiopsis lescurii, Oligotrichum falcatum, O. parallelum, and Rhizomnium nudum. The frequent occurrence of Aquilonium plicatulum, Brachythecium baicalense, Echinophyllum sachalinense, and Dicranum majus, and finding of Oedipodium griffithianum are other features of oceanic environment here.
