Epiphytic bryophytes were studied in the valley of the river Černá Ostravice (Beskydy Protected Landscape Area). All bryophytes growing from the ground up to the height of 2 m were recorded on 219 deciduous phorophytes with a minimum girth of 20 cm at breast height. Grey alder (Alnus incana) and European beech (Fagus sylvatica) were the most prevalent species of phorophytes. Sixty-one species of bryophytes (52 mosses, 9 liverworts) were discovered, three of them (Callicladium haldanianum, Orthotrichum patens, Syzygiella autumnalis) are listed on the Red List of the Czech Republic, and one (Callicladium haldanianum) is new for the PLA Beskydy. Two types of epiphytic communities were recorded that can be assigned to known alliances, Ulotion crispae Barkm. 1958 and Dicrano scoparii-Hypnion filiformis Barkm. 1958.
