Mt. Deogyusan, 1,614m in altitude, is located in the southwest of South Korea. Around Mt. Duckyu, many Korean endemic and rare plants are populated, so it is considered a very important biogeographical area where the temperature zones of northern and southern plants are crossed. Because it is the graceful figure of Mt. Duckyu, it is a common mountain where many tourists visit frequently. Continuous tourist's visit may cause a bad influence on vegetation around the climbing paths. Therefore, weed community around the climbing paths on Mt. Duckyu, where visitors exert a bad influence directly on its community by coming in and out, was surveyed phytosocialogically. Our surveys have been accomplished from July to August, 2003. Weed communities formed around the climbing paths on Mt. Duckyu were divided into several patterns and analysed. They have been divided into 8 communities and 4 subcommunities. Community A: Plantago asiatica community, A-a: Carex bostrychostigma subcommunity, A-b: Artemisia princeps var. orientalis subcommunity, B: Sasa borealis community, B-a: Carex siderosticta subcommunity, B-b: Veratrum parulum subcommunity, C: Rubus crataegifolius community, D: Hosta longipes community, E: Tripterygium regelii community, F: Miscanthus sinensis var. purpurascens community, G: Carex okamotoi community, H: Lespedeza maximowiczii community. The flora surveyed in these communities was constituted of 34 families, 83 genera, 12 varieties, and 92 species. Wild plants such as Plantago asiatica, Artemisia princeps var. orientalis, Rubus crataegifolius, Sasa borealis and Miscanthus sinensis var. purpurascens were mostly light loving plants and higher resistant plants against the stamping pressure.

Mountain Chungyeong, 879m in altitude, is located in the northeast of the middle area in Korea. Around Mt. Chungyeong, many Korean endemic and rare plants are populated, so it is considered a very important biogeographical area where the temperature zones of northern and southern plants are crossed. Because it is close to Seoul, a capital of Korea, it is a common mountain where many tourists visit frequently. Continuous tourist's visit may cause a bad influence on vegetation around the climbing paths. Therefor, weed community around the climbing paths on Mt. Chungyeong, where visitors exert a bad influence directly on its community by coming in and out, was surveyed phytosocialogically. Our surveys have been accomplished from August, 2001 to September, 2002. weed communities formed around the climbing paths on Mt. Chungyeong were divided into several patterns and analysed. They have been divided into 5 communities and 5 subcommunities. Community A: Plantago asiatica community, A-a: Erigeron annuus subcommunity, A-b: Carex. lanceolata subcommunity, B: Pseudostellaria palibiniana community, B-a: Carex siderosticta subcommunity, B-b: Galium trachyspermum subcommunity, C: Pueraria thunbergiana community, D: Lespedeza maximowiczii community, E: Rubus crataegifolius community, F: Oplismenus undulatifolius community, The flora surveyed in these communities was constituted of 47 families, 101 genera, 17 varieties, and 149 species. Wild plants such as Plantago asiatica, Erigeron annuus, Erigeron strigosus, Pueraria thunbergiana, Lespedeza maximowiezii, Rubus crataegifolius, Artemisia princeps var. orientalis, Artemisia japonica and Lysimachia clethroides were mostly light loving plants and higher resistant plants against the stamping pressure. Our result from the ranking all surveyed areas by the Bray-Curtis ordination method was very similar to the results from phytosocialogical table analysis.

A vegetation survey was conducted and analyzed on 25 survey plots of Betula ermanii communities in the subalpine zone of Mt. Gariwang, Mt. Balwang, Mt. Bangtae, and Mt. Hambaek in Gangwon-do. As a result of TWINSPAN and DCA analysis, the community was divided into a total of 3 communities: Betula ermanii-Quercus mongolica community(GroupI), Betula ermanii-Acer pseudosieboldianum community (GroupII), and Betula ermanii community(GroupIII). As a result of the vegetation structure analysis, Betula ermanii-Quercus mongolica community(GroupI) is located on the periphery of the Mt. Bangtae trail at altitude of 1,082~1,192m, and Betula ermanii-Acer pseudosieboldianum community(GroupII) is located on the ridges and slopes of Mt. Bangtae, Mt. Gariwang, and Mt. Hambaek at altitudes of 1,230~1,373m. Betula ermanii-Quercus mongolica community(GroupI) and Betula ermanii-Acer pseudosieboldianum community(GroupII) are currently dominated by Betula ermanii, but after long term, it is expected that they will transe to Quercus mongolica. The Betula ermanii community(GroupIII) is located the summit of Mt. Hambaek and the summit of Mt. Balwang at altitude of 1,428~1,464m. It is expected that the community will be maintained as Betula ermanii community, because Betula ermanii is very dominant, and so the next generation dominant species is maintained by Betula ermanii. Betula ermanii community generally appear above 1,000 m above sea level, and the higher the altitude, the more dominant the Betula ermanii are. As a result of the soil analysis, the soil characteristics shows a similar pattern to the subalpine belt of Daecheongbong Peak of Mt. Seoraksan and Banyabong Peak of Mt. Jirisan. As a result of the species diversity index analysis, the species diversity index was 1.210~1.293, the abundance index was 0.698~0.795, and the dominance index was 0.208~0.302.

The Baekdudaegan, spanning around 701 km from Hyangrobong to Cheonwangbong of Mt. Jirisan in South Korea, is rich in biodiversity and known as the main ecological axis of the Korean Peninsula. The Neuljae-Yuksimnyeong section of Marugeum in the southern part of the Baekdudaegan, particularly Mt. Deogyusan, is an area in which various types of vegetation appear depending on the environmental characteristics. The aims of this study were to investigate the current vegetation status at the Neuljae-Yuksimnyeong section of the Baekdudaegan and to provide basic data to aid systematic conservation and management through future classification of forest vegetation types. A vegetation survey was conducted using 637 plots from May to October 2019. Vegetation-type analysis showed that the vegetation units could be classified as a Quercus mongolica community group divided into seven communities: the Abies koreana community, Sanguisorba hakusanensis community, Persicaria hydropiper community, Quercus variabilis community, Quercus dentata community, Cornus controversa community, and Quercus mongolica community. The A. koreana community was subdivided into the Dryopteris expansa group and Picea jezoensis group. The Q. variabilis community was also subdivided into the Q. dentata group and Q. variabilis typical group. We concluded that special management plans for distinctive forest vegetation, including subalpine vegetation, grass or herb vegetation, and agricultural vegetation, should be prepared urgently to aid ecosystem preservation and enhancement.

This study was carried out for the purpose of supplying the basic data for artificial forestation, natural regeneration and ecological conservation etc., and obtaining information on alpine vegetation, by establishing vegetation units on the basis of phytosociological classification of community and studying growth pattern on the basis of species composition, hierarchy structure and population dynamics, for Taxes cuspidata naturally growing at the alpine districts in Korea. The importance value of Taxus cuspidata by districts mostly showed above 100 in the upper story but at Mt. Chiri and Mt. Hanra communities its value was comparatively low. In the middle story it showed lower value than that of upper story and not quite showed at Mt. Chiri. Taxus cuspidata communities in the lower story were only in Mt. Hanra, Mt. Odae and Mt. Sobaek, and their importance values were about 10 which were relatively low values. The communities were classified into five groups as Taxus cuspidata-Males baccata var. mandshurica, Taxus cuspidata-Abies nephrolepis, Taxus cuspidata-Abies koreana, Taxus cuspidata-Acer mono and Taxus cuspidata-Euonymus quelpaertensis by TWINSPAN analysis. Taxus cuspidata-Abies koreana community was distributed at the northern aspect of the mountain ridges and at higher elevation than other communities and distributed. Taxus cuspidata-Acer mono community was relatively low than the others and distributed at the hillsides of mountain. And Taxus cuspidata-Euonymus quelpaertensis communities were distributed at the relatively high elevation and northern and eastern aspect of the mountain tap, and Taxus cuspidata-Malus baccata var. mandshurica communities were distributed at the medium elevation, and southern and eastern aspect of the mountain ridge. In the relation between communities and environmental factors, it was correlated with aspect, elevation and topography at the first axis, and elevation, slope at the second axis.

The mound grave of Korean traditional funeral culture is a unique habitat which is a Zoysiagrass lawn being sustainable in proper management. We phytosociologically described an unusual Zoysiagrass vegetation with Gueldenstaedtia verna by the Zürich-Montpellier School's method and analyzed eco-floristic characteristics. A new association, Gueldenstaedtio-Zoysietum japonicae ass. nov. hoc loco, was identified and subdivided into festucetosum ovinae, typicum, and trifolietosum repensae. The subassociations were distinguished by the difference in species composition resulting from site accessibility and lawn management method. The association was assigned as not only a regional but also a locally-limited vegetation type, which distributes on a particular microhabitat with strong continentality in the Daegu regional subdistrict of Bioclimatological division. The Zoysiagrass vegetation of Korea was considered as a continental type apparently different from the oceanic type of Zoysion japonicae (Miscanthetea sinensis, Caricetalia nervatae). Mound graves in Korea should be acknowledged as a meaningful habitat for the in-situ conservation of biodiversity and phytocoenosen, despite being a secondary grassland of Gueldenstaedtio-Zoysietum japonicae.
