The plant cover of subalpine and alpine helt of Pokucko-Marmaroskie Mountains consists of semi-natural and natural plant communities. Some of these communities are endemic for the Eastern Carpathians. The aim of our work was a preliminary characteristics or common plant associations used as a pastures and their positioning in Polish taxonomy of plant communities. In years 2000-2004 we collected the data using Braun-Blanquet method. This paper contains the characteristics of Poo-Deschampsietum and Calamagrostietum villosae belonging to the class Betulo-Adenostyletea, Junco trifidi-Festucetum airoidis and Caricetum sempervirentis belonging to the class Juncetea trifidii and Mutellino purpureae-Nardetum (class Nardo-Callunetea). From the biological and agricultural point of view the reachest commmunities are Calamagrostietum villosae and Poo-Deschampsieteum. Described forms of these phytocenoses are different from those described by other authors for lower placed stands in Czywczyńskie and Bieszczady Mountains. They have typical combination of characteristic species but haven't any companion species belonging to the class Molinio-Arrhenatheretea. On the base of their agricultural usefulness and natural value we indicate the need of their protection. Communities Junco trifidi-Festucetum airoidis and Caricetum sempervirentis occure mainly in the alpine belt, above the reservation border, where pasturage is rare. A special emphasis is put on the characteristics of Caricetum sempervirentis because this natural phytocenose has never been mentioned in Polish literature as an association. The most devastated by pasturage plant cover is placed near farmers building. At these places the vegetation is dominated by Nardus stricta. We described the most common form of such phytocenoses as an association Mutellino purpureae-Nardetum. Plant communities mentioned above occupy slopes of investigated mountains in the original topographic scquence. It is due to decrcasing with altitude human activity and changing environmental conditions.
