Abstract
In general, for high mountains part of Chornohora and Marmaros ranges 27 species are known from the official lists, which is based on the results of own researches, herbarium sources (Ivan Franko National University of Lviv (LW), State Natural History Museum of the National аcademy of sciences of Ukraine (LWS) and literary sources. There are 27 rare species of Chornohora range, among them five species of Marchantiophyta and 22 of Bryophyta, while five species from Bryophyta are known for the high mountains of Marmaros range. During recent years, the species Scapania helvetica Gottsche, S. verrucosa Heeg, Hamatocaulis vernicosus (Mitt.) Hedenäs, Pohlia elongata Hedw have been found. Among the region-rare species for the territory of Chornohora were confirmed localities for Bryophyta: Hygrohypnum duriusculum (De Not.) D.W. Jamieson, Lescuraea radicosa (Mitt.) Mönk., Sciuro-hypnum reflexum (Starke) Ignatov et Huttunen., Syntrichia virescens (De Not.) Ochyra, for the high mountains of Marmaros – Cephalozia pleniceps (Aust.) Lindb (Marchantiophyta). Of the 76 species of the Arctic-Alpine element in the flora of mosses, recently have been found: Marchantiophyta: Barbilophozia sudetica (Nees ex Hübner) L. Söderstr., De Roo et Hedd., Gymnomitrion concinnatum (Lightf.) Corda, Moerckia blyttii (Morch) Brockm. , Scapania subalpina (Nees et Lindenb.) Dumort., Bryophyta: Blindia acuta (Hedw.) Bruch et Schimp., Grimmia incurva Schwägr., Hymenoloma crispulum (Hedw.) Ochyra, Hypnum callichroum Brid., H. vaucheri Lesq., Kiaeria blyttii (Bruch et Schimp.) Broth., K. starkei (Web. et Mohr) Hag., Oligotrichum hercynicum (Hedw.) Lam. et DC., Philonotis seriata Mitt., Polytrichastrum alpinum (Hedw.) G.L.Sm., P. sexangulare (Brid.) G.Sm., Tortella tortuosa (Hedw.) Limpr., Tortula hoppeana (Schultz) Ochyra. Research of mosses of the high mountains of Chornogora and Marmaros ranges showed significant changes in composition of species. In the last decade there were not found some of rare species, both with the status of officially, and with the regionally rare. Further detailed study of the species composition of mosses of high mountains, the state of populations of species will enable the development of scientifically based recommendations for conservation of rare species.
