Papp, B.: Contributions to the bryophyte flora of Mt Taebaek, South Korea

MATERIALS AND METHODS The investigated area The Taebaek mountain range runs through the Korean Peninsula from north to south along the east coast. Mt Taebaek ( 1,567 m), one of the high mountains of this range is located 10 km southwest of Taebaek city, Kangwon province. The summers are hot and moist while the winters cold and dry. Mean temperatures at Taebaek city range from 20.8 °C in August to -4.9 °C in January and the mean annual precipitation was 1,300 mm during the last 30 years. Brown forest soil is prevalent and bedrock.is composed of metamorphic rocks (Precambrian schist and phyllite) covered by Palaeozoic and Mesozok sedimentary rocks and Mesozok igneous rocks. The low to middle altitude ranges are covered by mixed forests composed of Abies bolophylla, Acer pictum subsp. mono, Acer pseudosieboldianum, Betula ermanii, Fraxinus sieboldiana, Malus baccata var. mandsburica, Pinus koraiensis, Quercus mongolica, Sorbus commixta, Taxus cuspidata, and Tilia amurensis. Methods Collections were made in October of 2005. Different types of temperate deciduous forest and stream valleys were explored for bryophytes on various substrates (soil, exposed and shady rocks, tree barks and decaying wood). The collected material, shared by the respective institutions, have been deposited in the herbarium of the Hungarian Natural History Museum (BP) and in the collection of the Korean Lichen Research Institute of Sunchon National University (KoLRI). Several works have been used for identification and consulting the nomenclature (GAO and CROSBY 1999,2003, LI and CROSBY 2001, Wu and CROSBY 2002, 2005, NOGUCHI 1987, 1988,1989, 1991, 1994, HILL etal. 2006, HONG 1997, 2003). The floristical results that appeared new for the country had been analysed according to the checklists of CHOE and CHOI (1980), HOANG (1991), HONG (1997), YAMADA and CHOE (1997) and the identification key for liverworts andhornworts (HONG 2003). Earlier data on the bryophyte flora of the Taebaek mountain range can be found in SONG (1999). This paper deals with the terricolous bryophyte communities of mixed coniferous and deciduous broadleaf forests and the evergreen coniferous forests of the mountain range with a record of 80 bryophyte taxa. The common species of this list and our findings are analysed. Site details 1.
