The Poloniny National Park, located largely in the Bukovské vrchy Mts, is the easternmost
protected area in Slovakia. It is situated within the Eastern Carpathians and represents
a special area in Slovakia, with the largest complex of primeval forests in the country.
The bryophyte flora of this region has been relatively well studied in the past century
and so far 375 bryophyte taxa have been reported from the territory of the national
park. This paper contributes to the knowledge on the bryophyte flora of the Poloniny
National Park. We recorded a total of 117 bryophyte taxa (one hornwort, 16 liverworts,
and 100 mosses), out of which 12 are reported as new for the region. Two species are
considered as endangered (EN) in Slovakia (Dicranum viride, Zygodon rupestris), three
are vulnerable (VU) (Anacamptodon splachnoides, Anomodon rugelii, Didymodon spadiceus),
four are near-threatened (NT) (Buxbaumia viridis, Orthotrichum patens, Phaeoceros
carolinianus, Ulota bruchii), and three are reported here as new for the country (Philonotis
capillaris, Tortula schimperi, Ulota crispula).
