Today, there is still a lack of information about individual groups of bryophytes in many nature reserves. This segment of the flora in the Uzhanskyi National Natural Park has not been sufficiently studied. Our research was devoted to the epiphyte fraction of bryoflora, which has an important indicator value in determining the age of the forest, its primacy and the degree of anthropogenic load on it. As a result of our research, 75 species of bryophytes were established on the territory of Uzhanskyj National Natural Park and its surroundings, of which 14 are liverworts and 61 species of moss. Representatives of the families Metzgeriaceae (4 species), Porellaceae (2), Frullaniaceae (2) prevail among liverworts. The liverworts found on the trees of the park are mainly facultative epiphytes; much less often – epigeids or epixyls. The most common trees in the park are Metzgeria furcata (L.) Dumort., M. conjugata Lindb., Radula complanata (L.) Dumort., Frullania dilatata (L.) Dumort., Lejeunea cavifolia (Ehrh.) Lindb., Plagiochila porelloides. Among the mosses, Orthotrichaceae (9 species), Brachytheciaceae (8), Neckeraceae (7), and Plagiotheciaceae (5) were the richest. Obligatory epiphytes of the park should be considered Syntrichia papillosa (Wilson) Jur., Zygodon rupestris Schimp. ex Lorentz, Ulota crispa (Hedw.) Brid., species of Orthotrichum s.l. Facultative epiphytes (epiphyto-epiliths) include species of the genus Anomodon Hook. & Taylor, Neckera s.l., Hypnum cupressiforme Hedw., Isothecium alopecuroides (Lam. ex Dubois) Isov., Paraleucobrium longifolium (Hedw.) Loeske, Leucodon sciuroides (Hedw.) Schwaegr. and a number of other taxa. In addition to the predominant obligate and facultative epiphytic mosses, epixillae, epigeids, and occasionally epiliths occur on the trunks of the park’s phorophytes. Brachythecium geheebii Milde, included in the Red Book of European bryophytes, Dicranum viride (Sull. & Lesq.) Podp.), included in the list of species of the Berne Convention, and Neckera pennata Hedw., which is a rare species in the Ukrainian Carpathians, were found in the Uzhanskyi National Natural Park.
