In total 21 epiphytic moss species were found during research which composes characteristic species combinations making apparent difference between associations. As a result of field research and numerical analyses, three separate groups of samples corresponding to seven associations and one community within three alliances: Ulotion crispae and Syntrichion laevipilae (Frullanio dilatatae-Leucodontetea sciuroidis class) as well as Neckerion complanatae (Neckeretea complanatae class) have been distinguished. A synopsis of the epiphytic moss communities is proposed. The most interesting is the association of Orthotrichetum crenulati which is described here for the first time. Two species of epiphytic mosses (Orthotrichum crenulatum and O. pallens) are new to Kyrgyzstan.
