In this study, the epiphytic bryophyte succession of the Buxus sempervirens L. forests in Fırtına Valley (Çamlıhemşin-Rize, North Türkiye), one of the nine biodiversity hotspots in Türkiye, was investigated. For this pur-pose, a total of 60 sampling plots were taken from the live trunks of B. sempervirens trees of different ages. Twenty-nine epiphytic bryophyte species were determined (24 mosses and 5 liverworts) within the sample plots. Also, six different life form types and four different habitat affinity categories were determined. Among them, the mat type life form is in first place with 34.4% and the cortico-saxicolous species are the most common with 51.7%. Two-way indicator species analysis (TWINSPAN) classified the epiphytic bryophyte communities on B. sempervirens trunks at the second level into two main clusters (A and B) and three sub-clusters (A1, B1 and, B2). Detrended correspondence analysis (DCA) axis 1 was interpreted as gradient along the height of the epiphytic habitat (from the lower base to the upper zone) on trunks and the DCA axis 2 was interpreted as gradient of moisture (from mesic to xeric). Exsertotheca crispa (Hedw.) S. Olsson, Enroth & D. Quandt was the species with the highest index of ecological significance (IES) value on the lower bases of the aged trees. Species diversity and epiphytic cover in the upper zones were lower than in the basal and middle zones in the study area. While Metzgeria furcata, (L.) Corda, Oxyrrhynchium hians (Hedw.) Loeske, Plagiothecium nemorale (Mitt.) A.Jaeger, and Radula lindenbergiana Gottsche ex C.Hartm were only found on old trees, Ctenidium molluscum (Hedw.) Mitt. and Pseudoleskeella nervosa (Brid.) Nyholm were only found on middle-aged trees.

The present study was performed on the Samanlı Mountains, which is extending from Sakarya province to Yalova province, in North-West Turkey. During this study, eight field trips were organized to the research area at different seasons between the years 2013 and 2016. Throughout these studies, with an examination of 3630 bryophyte specimens collected from 189 stations, together with 2 from Anthocerotophyta (hornworts), 61 from Marchantiophyta (liverworts), 306 from Bryophyta (mosses), in total 369 specific and infraspecific taxa, belonging to 70 families and 156 genera, have been identified. According to grid square system of Turkey which was adopted by Henderson, 68 taxa for A1 square and 24 taxa for A2 square are new records. Among them, Fissidens curvatus Hornsch., Thamnobryum neckeroides (Hook.) E.Lawton, Plagiothecium neckeroideum Schimp. and Riccia beyrichiana Hampe were recorded for the second time in Turkey. In addition, the present paper reports the first records of Cephaloziella massalongi (Spruce) Müll.Frib, which has been classified as rare (R) in the Red data book of European bryophytes, and Scapania scandica (Arnell et H.Buch) Macvicar in Turkey. Some morphological features, the ecological characteristics and the distribution map of the species are given, along with photographs of diagnostic details.
