  • This study was carried out to define the characteristics of the identified ground-dwelling invertebrate communities at Nari basin and Tonggumi area in Ulleungdo Island, designated as a nationally important agricultural heritage. The habitat types were divided into the following categories: crop land, forest, and ecotone, and the soil-dwelling invertebrates were collected according to habitat type. The ground-dwelling invertebrates were collected using a pitfall trap, and a self-organizing map (SOM) was applied to the invertebrates dataset to define the characteristics in invertebrates distribution. The SOM clearly classified the relevant information into four clusters, and extracted ecological information from the invertebrates dataset. The cluster II was composed of invertebrate communities which are collected in the Tonggumi area. The Tonggumi area is where mountainous areas were developed for agricultural purposes, which has geographical features commonly observed in Ulleungdo Island. It is noted that the cluster II has different characteristics as compared other clusters. The results of this study are expected to be used for the preservation of agricultural environment and maintenance of biodiversity by providing basic data, on the biotope of Ulleungdo Island designated as a nationally important agricultural heritage and information on the characteristics of the applicable ground-dwelling invertebrate communities.

  • This study is thing about eco-tourism activated Mt. Gede Pangrango National Park in Indonesia. Indonesia is full of eco-tourist resources with the possession of the tropical forest. Particularly, Gede Pangrango National Park on the west of Java island has so plenty of bio-diversity that the UNESCO designated this park as the World Biosphere Reserve. By virtue of this, various visitors all over the world are visiting Gede Pangrango Park for doing research, education, hiking and camping. However, Indonesia lags behind other countries in convenience facilities for visitors, so their visiting programs are actually insufficient. In order for eco-tourism to be revitalized, there should be physical improvement in visiting facilities, management of a variety of visit programs, and local residents' participation & projects to increase the income of local residents. This study is going to seek for the environment-friendly management plan suited for the properties of the park and improvement plan for eco-visiting facilities by closely grasping the actual condition of the eco-tourism of Gede Pangrango National Park.

  • Mites in the family Ascidae are soil dwelling predators of small insects which would have potential to be used as biological control agent. In Korea, 10 genera of 24 species were recorded in the family. During the soil acarine biodiversity study, Asca bicornis Canestrini & Fanzago, 1877 was discovered from moss habitat on Muljangori craer lake 936 m alt in Hallasan mountain in Jeju which was designated as UNESCO Biosphere reserve and World herigate site. We reports this as a new record to Korean Mesostigmata fauna, and provide the morphological description. This species has morphologically characteristic as all dorsal setae nude and needle shaped, lateral caudal projection of Z4 shaped, which are different from the con-general species of A. aphidioides.

  • Targeting a rooftop biotope created in urban area, this study aims at verifying a creation technique reflecting an urban biosphere reserve concept as well as its function as the habitats of various wild animals. To this end, a set of processes of a biosphere reserve-based basic conception and master plan, sectoral plans, construction and monitoring were applied to the rooftop of 12-story UNESCO Building in Seoul. In particular, the rooftop habitats were divided into core area, buffer zone and transition area, and habitats and facilities suitable to the characteristics of each space were planned. By aligning a plantation planning map with environmental conditions such as topography and water, creation of diverse habitats was enabled. As a result, a set of various habitats including wetlands, wild grassland, shrubs, forest trees and vegetable fields was created at the site. Species living in these habitats included 148 plant species, 62 insect species, 2 amphibian species, 3 fishery species and 3 bird species. The rooftop eco-park of UNESCO Building, which was created one year ago, is assessed as an important space for conservation of biodiversity as well as a place where a biosphere reserve concept was well applied. Meanwhile, for this rooftop biotope to be a pioneer of urban biosphere reserve-based types, a number of principles & methodologies suggested in this study need to be applied, In a perspective of landscape ecology, maintenance efforts should be linked with green areas in neighboring areas, which are the sources of species, In addition, considering that the rooftop biotope is a restored ecosystem, theories and approaches from restoration ecology should be applied. On-going monitoring on environmental changes is also required as the site is located in the urban center, Ultimately, rooftop biotopes including the case study area should contribute in promoting the socio-economic, cultural, and spiritual sustainability as well as environmental sustainability of a city.

  • We analyzed the spatio-temporal distribution characteristics of water quality and phytoplankton communities in the Isa Stream systems (ISS) from Sangsa Lake to Suncheon Bay. Sangsa Lake showed relatively oligotrophic and mesotrophic conditions, but the freshwater and mixed brackish water zones showed more severe eutrophication than Sangsa Lake and Suncheon Bay due to the influence of industrial waste such as livestock waste. In terms of the phytoplankton community, the number of phytoplankton species was higher in freshwater and mixed brackish water zones than in Sangsa Lake and Suncheon Bay, but the cell density and Chlorophyll-a concentrations (Chl-a) were relatively high in Sanga Lake and Suncheon Bay. In particular, the mesotrophic species Fragilaria crotonensis and Asterionella formosa showed different dominance in the surface and bottom layers, and the influence of A. formosa was significant in the freshwater and mixed brackish water zones in spring and summer. However, Skeletonema costatum-ls, a eutrophic indicator species, dominated in mixed brackish water zones to seawater in autumn and winter. Thus, the severe eutrophication and rapid environmental changes in the ISS could seriously damage the coastal ecosystem in Suncheon Bay. These ecosystem changes are threatening in terms of conservation and management of the UNESCO Suncheon Biosphere Reserve and Yeoja Bay including Suncheon Bay, which recorded the first Ramsar wetland in Korea. Therefore, further research is needed to establish an in-depth management plan.

  • This study is analyzed the environmental ecological status of Suncheon Bay and its applicable possibility to the selection criteria of UNESCO World Natural Heritage (hereafter Criteria). The study shows that the formation process of the tidal-flats in Suncheon bay could apply to the Criteria VIII, "to be outstanding examples representing major stages of earth's history." The landscape pattern of Suncheon Bay is deduced various patterns based on 5 biotope types: tidal-flat, rice-paddy, field area, coniferous natural forest, and broadleaf natural forest. Its landscape characteristic is a harmonized composition of various landscape including mountains, rivers, fields, and tidal-flats. It is judged that the unique landscape of Suncheon Bay falls under the criteria VII, "areas of exceptional natural beauty and aesthetic importance." In addition, Suncheon Bay, the habitat of the Hooded Crane as internationally endangered species, comes under the criteria X, "the most important and significant natural habitats for in-situ conservation of threatened species." The study shows, however, that any other designation for protected area including national park or biosphere reserve is a prerequisite for designation of World Nature Heritage. In particular, it could evaluate whether it is qualified of the Criteria after the integrated conservation and management to the Sucheon bay as well as the southwestern tidal-flat is preceded.

  • Soraksan National Park and Odaesan National Park, that are 20.7 km apart, should play an important role as habitats and corridors for wildlife because they are located in the center of Baekdudaegan. However, landscape features such as small area, fragmentation, and geographic isolation seem to impede the proper ecological functions of these two national parks. Using GIS technique, we examined the pattern of fragmentation in these two national parks and adjacent regions (Sokcho-si, Goseong-gun, Inje-gun, Yangyang-gun, and Hongcheon-gun) encompassing a total of $4573.5km^2$ in area. We then selected the patches suitable for an endangered carnivorous species, leopard cat, based on habitat conditions, and identified the network and stepping stone among patches to enable leopard cats to migrate. Diverse roads and artificial facilities in the study area generated a total of 24,701 patches: 39 patches among these were selected as potential habitats upon considering the habitat condition such as vegetation types and minimum area for leopard cat. Three patches nearby Gyebangsan and Bangtaesan were identified as a potential network center to relieve the effects of fragmentation and isolation of the two national parks. Our results also showed that patches containing Jombongsan and Bangtaesan would act as a source patch from there leopard cats can disperse to both national parks. It is an urgent task to identify the pattern of fragmentation and the connectivity between patches in national parks and adjacent areas for wildlife conservation because almost all national parks confront land- scape problems similar to the two national parks examined in this study.
