Bryophyte flora of Hrončecký grúň National Nature Reserve (Poľana Mts, Central Slovakia)

This study deals with the Hrončecký grúň National Nature Reserve, characterised by virgin beech-fir forests, and documents its bryophyte flora. A total of 91 bryophyte taxa were recorded, including 22 liverworts and 69 mosses. Among these, two are regarded endangered in Slovakia (Dicranum viride, Orthotrichum alpestre), four are vulnerable (Anomodon rugelii, Callicladium haldanianum, Neckera pennata, N. pumila), three are near threatened (Buxbaumia viridis, Fuscocephaloziopsis catenulata, Lewinskya striata), while four species are not included in the current checklist of Slovak mosses but occur in the country (Lewinskya fastigiata, Schistidium lancifolium, Thamnobryum neckeroides, Ulota intermedia). Additionally, eight species are newly reported for the Poľana Protected Landscape Area. This survey contributes to a bridging of gaps in the knowledge of bryophyte distribution and reinforces the need for targeted conservation and monitoring efforts in this unique landscape.
