It is important to consider urban parks and greenery not only from the viewpoint of amenity or aesthetics but also from the viewpoint of biodiversity. In this study, we focused on bryophytes (mosses), and analyzed how existence of artificial structures in urban greeney, such as concrete curbs and stone walls, affect species diversity of bryophytes. Kyoto Gyoen in Kyoto City, western Japan, was selected as the study site. In consideration of kinds of substrates on which bryophytes grow, microhabitats of Kyoto Gyoen were divided into ten types including concrete curbs and stone walls. In each type of microhabitats, we selected the area where bryophyte diversity was highest, and established a quadrat for bryophyte flora survey. Our results showed that the number of bryophyte species and growth forms and the value of diversity indices on concrete curbs or stone walls were higher than the averages of those. The bryophyte species were divided into the four groups by TWINSPAN as follows: Group A (epiphyte species), Group B (rocky species), Group C (roadsides, grassland or forest species), and Group D (waterside species). Bryophytes classified into Group B (rocky species) were mainly recorded on concrete curbs or stone walls. It was considered that the existence of artificial structures (concrete curbs and stone walls) provided favorite habitats for the bryophytes classified into Group B (rocky species), which mainly grows on concrete or rocks, and enhanced species diversity of bryophytes in Kyoto Gyoen.

This study presents a survey of the bryophytes of evergreen broad-leaved forest near Baekyaki Oreum in Gujwa-Seongsan Gotjawal in the eastern part of Jejudo Island, Korea. A total of 53 taxa belonging to Bryophyta (11 families 26 genera 39 species) and Marchantiophyta (9 families, 9 genera 14 species) were determined, and the liverwort index was found to be 26.4%. The predominant life-form was the mat type. The rates of bryophytes dominating at mesic to hygric sites were higher than those of bryophytes, which were mainly observed in xeric habitats. These values indicate that the forest areas in this study area have a high density level. Upon an investigation of the substrates, bryophytes on rocks were most diverse. It was also found that volcanic rock masses of various sizes lay scattered over the study area and offer numerous micro-habitats for bryophytes. This is related to the characteristics of Gotjawal. We consider that more detailed studies should be conducted on regional scales to establish the bryophyte flora of Gotjawal and the evergreen broad-leaved forests of Jejudo Island.

Recently, it has become known that Gotjawal terrain is an important area, therefore the study on this area has conducted in the geological, ecological, and cultural aspects. The studies on bryophytes of Gotjawal, however, have not been sufficiently performed. This study presents a survey on the bryophytes of the evergreen broad-leaved forest of Cheongsu-ri at Hangyeong Gotjawal in the southwestern part of Jejudo Island, Korea. A total of 72 taxa belonging to the Bryophyta (18 families 43 genera 55 species) and Marchantiophyta (11 families 13 genera 17 species) were determined and the liverwort index was 23.6%. Predominant life-form was weft. The rates of the bryophytes dominating in mesic to hygric sites were higher than the bryophytes mainly observed in xeric habitats. These values indicate that the forests are widespread and dense in this study area. Upon an investigation of the substrates, the bryophytes on rocks were most diverse. The results appear to stem from the fact that volcanic rock masses of various sizes lay scattered over the study area, offering numerous micro-habitats for bryophyte due to one of the characteristics of Gotjawal. We suggest that more detailed studies should be conducted at the regional scale to establish the bryophyte flora of Gotjawal and the evergreen broad-leaved forests on Jejudo Island.

This study presents a survey of bryophytes in a subtropical forest of Nabeup-ri, known as Geumsan Park, located at Aewol Gotjawal in the northwestern part of Jejudo Island, Korea. A total of 63 taxa belonging to Bryophyta (22 families 37 genera 44 species), Marchantiophyta (7 families 11 genera 18 species), and Anthocerotophyta (1 family 1 genus 1 species) were determined, and the liverwort index was 30.2%. The predominant life form was the mat form. The rates of bryophytes dominating in mesic to hygric sites were higher than the bryophytes mainly observed in xeric habitats. These values indicate that such forests are widespread in this study area. Moreover, the rock was the substrate type, which plays a major role in providing micro-habitats for bryophytes. We suggest that more detailed studies of the bryophyte flora should be conducted on a regional scale to provide basic data for selecting indicator species of Gotjawal and evergreen broad-leaved forests on Jejudo Island.

This study introduces the bryological history and literature of the Korean Peninsula. The French missionary Urban Faurie was the first person to collect Korean bryophytes at the beginning of the 20th century. Most of his bryophyte collections from Korea were studied and recorded by Jules Cardot (for mosses) and by Franz Stephani (for liverworts). Japanese studies of Korean bryophytes were described in chronological order. Hong Won Shic and Choe Du Mun carried out an inventory and flora research on bryophytes in South Korea. The most recent bryological studies of North Korea are also reviewed here as a reference.

Over twenty thousand types of bryohytes are existed in the world. Bryophytes are generally considered to be primitive plants and seriously neglected by even in botany area. Bryophytes includes mosses, liverworts, and hornworts. They thrive in humid environments and require water to survive. Some types, however, can recover after serious dehydration, even after years of complete dehydration. They generally absorb water and nutrients not from roots which is called rhizoid, but through entire body. The rhizoids are nonchlorophyllose fillamentous branches and attach the body to substratum such as soil and rocks. The attachment of mosses in soil surface provides a good protection from soil erosion by runoff water. In this presentation, reviewed and discussed are ecological characteristics and engineering perspectives of mosses, particularly with respect to soil and water conservation.

This study presents a survey on the bryophytes in Dongbaek-dongsan located at Seonheul Gotjawal on the north-eastern face of Mt. Halla in Jeju Island, Korea. A total of 85 taxa belonging to the Bryophyta (22 families 44 genera 62 species), Marchantiophyta (12 families 16 genera 23 species) were found. Among them, 3 moss species, Diphyscium perminutum Takaki, Racomitrium japonicum Dozy & Molk., and Isopterygium minutirameum (M$\ddot{u}$. Hal.) A. Jaeger. were new additions to the bryophyte flora of Korea. The liverwort index was 27.0%. Predominant life-form was weft. The rates for the bryophytes dominating in mesic to hygric sites were higher than for the bryophytes mainly observed in xeric habitats. We considered that the composition and distribution of species are affected by the different environmental factors according to the evergreen broad-leaved forests, wetlands and exposed spaces. Moreover, the rocks were the substrate type that play a major role in providing the micro-habitats for bryophytes in this area. Particularly, the bryophytes of swamps in this area were very unique and various for its limited space and showed plant communities with mosaic spatial pattern, along with vascular plants. We suggest more detailed and comprehensive studies on the swamps where endemic fern Mankyua chejuense B. -Y. Sun, M. H. Kim & C. H. Kim inhabits to provide valuable information for the conservation and restoration of the species and habitats.

This study presents the flora of nonvascular plants (bryophytes) and vascular plants within the Wangpicheon Ecosystem and Landscape Conservation Area in Korea. The time of the survey was divided into four seasons. The fieldwork was conducted for a total of 18 days from November of 2016 to October of 2017. The land plants in the Wangpicheon conservation area were identified as 758 taxa with 164 families, 455 genera, 698 species, 10 subspecies, 47 varieties and 3 forms. Among them, bryophytes amounted to 122 taxa and vascular plants numbered 636 taxa. Native plant amounted to 693 taxa. In total, there are 113 floristic target species in Korea, including one level V taxon, in this case Swertia wilfordii; six level IV taxa; 31 level III taxa; 38 level II taxa; and 37 level I taxa. There are nine endemic plants, including Sillaphyton (=Peucedanum) podagraria, which is the endemic genus; two rare plants; fifteen northern plants; and one southern plant as target plants adaptable to climate change. Also, there are forty-six naturalized plants and five ecosystem-disturbance organisms. The results of this study suggest several species that should be preserved and can serve as basic information with which to establish conservation and management plans for the Wangpicheon conservation area.

Algific talus slopes provide microclimates suitable for disjunct or relict populations of northern plant species at low elevation habitats in the temperate zones. The propose of this study was to assess the phytogeographical significance and produce a strategy for the comprehensive conservation of the vegetation on algific talus slopes. Therefore, we studied the floristics of bryophytes on 15 algific talus slopes in Korea. The bryophytes on the algific talus slopes in Korea consisted of 59 families, 138 genera, 226 species, two subspecies, and five varieties, totaling 233 taxa. Peculiarly, many northern bryophytes, such as Andreaea rupestris var. fauriei (Besch.) Takaki., Buxbaumia minakatae S. Okamura, Racomitrium lanuginosum (Hedw.) Brid., Hylocomium splendens (Hedw.) Schimp., and Pleurozium schreberi (Willd. ex Brid.) Mitt. were found on the algific talus slopes. Of them, unrecorded species from south Korea numbered 14 taxa and unrecorded species from the Korean peninsula numbered seven taxa. A similarity analysis based on the bryophyte flora showed that the index of similarity between regions with similar environmental factors was high. This means that the bryophyte flora composition on each algific talus slopes was affected by topography and microclimate. Algific talus slopes are phytogeographically significant microhabitats where northern plant species that advanced southward during the latest glacial age have been isolated and adapted. However, algific talus slopes have constantly been destroyed or damaged by humans without consideration of conservation. Conservation strategies to ensure the biodiversity and effective management of algific talus slopes in Korea are discussed in detail.
