  • This study was accompanied to develop the management and application plans as resources for rural tourism through the analysis of distribution characteristics, inhabitants' practical use, need item for management and application, and aesthetic/recreation function of Palustrine wetland in rural area. The 2.3 Palustrine wetland per farm village were located, and 77.5% of total wetland was used by agricultural water, landscape, rural tourism The management and water quality were steadily getting better in used wetland than in unused wetland. Also, 91.8% of respondents answered that there is a practical use plan afterward, and much preferred the mode of ecotourism through restoration of ecological wetland. As the results from the appropriateness evaluation of management and application in used wetland for ecotourism, improvement item was required in observation deck, entrance lane, guidance facilities etc. And, insufficient result was deduced in appropriateness of operation program and special learning course, and in participation of inhabitants and experts. The result of evaluation of the aesthetic and recreation functions generally appeared high, but the need improvement item was required in artificial water wall and plantation base that deteriorate biological diversity. These results will be used to data for conservation, management and practical use of wetland, an important natural resource in farm village, which are confronted in crisis of land reclamation by use reduction of use and false management.

  • This research aims to classify wetland types and evaluate functions of a dam lake. The case study area is Boryung lake in Boryung City. In this study was carried out based upon field surveys, drawing maps and publication, and modified-RAM which can evaluate the general functions and conservation values of wetlands. Eight functions of 2-12 variables each are analyzed for assessing the wetland functions. The analysis shows that several types of wetlands were identified, such as Palustrine/ Perennial/ Hydrophytes, Palustrine/ Perennial/ Openwater, Palustrine/ Seasonal/ Herbal, Palustrine/ Seasonal/ Shrub and Scrub, Palustrine/ Seasonal/ Hydrophye, and Riparian/ Seasonal/ Shrub in the Boryung lake. The average level of functions of the wetlands is very "HIGH", and it is recommended that prompt conservation measures should be taken.

  • This study analyzed the changes in land-cover and sedimentary environment before and after flooding through drone images and sediment analysis for the Seomjin River Chimsil Wetland. The results showed that the area of some land-covers such as sand bar, grass, and trees were continuously changed. The acidity level of the sediments in the Seomjin River Chimsil Wetland was weakened gradually by flooding and EC was also decreased. The levels of organic matter, effective phosphoric acid, and CEC, however, were fluctuating depending on branches, which seems to be the result of landization as new sedimentary environment was developed and vegetation was settled after the flood. Average mean size of river sediments was found to be fine sand, and it exhibited various particle size characteristics from granule to medium silt depending on the location. As the sedimentary environment changed due to the effects of floods and typhoons, the particles were granulated or grain refined depending on the position. In the Seomjin River Chimsil Wetland, there were factors that could interfere with geomorphic development and sedimentary environment, contamination sources in and around the wetland, and natural threat factors. Therefore, in this study, a conservation and management plan was proposed to remove these threat factors and to preserve the scarcity, naturalness, and dynamics of Seomjin River Chimsil Wetland.

  • Many studies conducted in Kenya regarding water resource governance have focused on the mandate of Water Resource Users Associations (WRUAs) with less attention being accorded to their effectiveness in conservation of wetlands. This study assessed the effectiveness of WRUA committees, and challenges faced in conservation of Rwamuthambi Sub-catchment. The study employed exploratory descriptive research design. Data was collected through questionnaires, semi-structured interviews, observations and review of secondary data. Chi square and descriptive statistics was used to analyze the data. The survey results revealed that only 15% of WRUA committee understood water resources management while 35% were aware of relevant legislations. Factors of wetland degradation showed significant association with existence of WRUA (χ2 (4, N=180) = 20.46, p< .01) where (χ2- chi square (degrees of freedom, N = sample size) = chi-square statistic value, p = p value), although WRUA contributions were perceived differently per agro-ecological zone (χ2 (8, N=147) = 15.51, p>.05). Challenges unearthed were inadequate financial and human resources, lack of understanding, ineffective collaborative governance, poor support from county government and private ownership of riparian land reserve. There is need for WRUAs to embrace collaborative governance for effective conservation of wetlands. Integration of sub catchment management plan with county land use plans and policy review is also required.

  • The purpose of this study is to develop a integrated(fusion) utilization model aimed at maximizing the development/management functions of urban estuarine area and to present an integrated concept by analyzing the existing document and data. The main points of this study are as follows: 1) The integrated utilization model suggested in this paper goes beyond the existing idea of sustainable utilization and conservation, putting an emphasis on rational decision-making in estuary management and peaceful coexistence between human and nature. 2) Policies for utilization/development/conservation/regeneration of urban estuarine area include the establishment of communication system between human and nature and a safety net considering both human and nature, the support for environment-friendly community development and the importance of preserving valuable ecosystem and wetland habitat. 3) Lastly, this study suggested that the major tasks for the fusion utilization model development are the integrated management of estuary areas, the conservation and preservation of wetland ecosystem, proper utilization of estuary's productivity, and the introduction and action plans of the integrated management model including the best way to address contamination and disaster management.

  • Urban streams are degrading functional role due to development and pollution. This study chose the representative stream of Do-rim and identified flora and fauna. The ecological survey aimed at identifying indicator of urban streams for measuring urban healthiness and we discussed the possibility of wetland conservation area. From the beginning of Dorim stream to An-yang mixture we were successfully identified 113 species of plants, 9 of mammals, 23 of birds, 4 of amphibians, 2 of reptiles and 2 of fish species. Terrestrial insects were 71 species. The wetland vegetation is quite various and we suggested 4 different vegetation zones (aquatic vegetation zone, emergent zone, riparian-meadow zone, riparian-woodland zone) depending on distance from the flowing water stream and vegetation characteristics for urban stream management.

  • This study aims to provide basic data for the decision-making process in selecting sites for wetland restoration projects. To this end, the current list of demaged wetlands was identified based on the findings from the nationwide monitoring project in 2016 targeted at wetlands in inland areas. Then, to determine the necessity of restoration for these demaged sites, the cause of demage was investigated, and their conservation value was examined from an ecological and legal perspective. The 2016 monitoring project identified a total of 20 demaged wetlands, of which one site was deemed to have high conservation value through analysis of its ecological and legal values and on-site reviews. The results of this study are expected to support policymakers' decision-making in selecting wetlands for restoration projects since it identifies priority sites among demaged wetlands that require immediate restoration efforts. It should also be pointed out that wetlands in South Korea cannot benefit from legal protection despite their high conservation value unless they have a designated status as protected areas.

  • To reveal conservation value of Sowhangbyungsan-neup among wetlands in Mt. Odae designated as a Ramsar convention site in 2008, ecological characteristics were investigated. The maximum depth of sediment was 86cm and average at central part was 56cm. Average pH of water was 5.8 and this indicates that this wetland has the characteristics between bog and fen. Average electron conductivity was $11{\mu}S$/cm, which is the lowest among Korean wetlands. Nutrient status was oligotrophic based on contents of cation, nitrate, ammonia, soluble reactive phosphorus in water. Out-flow of water was related with the 3 day cumulative precipitation. Soil texture was loam and nutrient level was very low. Vascular plants of 45 family, 95 genus, 121 species, 2 subspecies, 16 variety, 4 forma, total 121 taxa were recorded. Main plant communities on Sphagnum base were Osmunda cinnamomea community, Carex dispalata community and Carex curta community. The results indicated that this wetland has very different ecological characteristics than others in Korea and deserves conservation value well. Also, this study revealed that there is no evident threatening factor and this wetland will have characteristics of fen continuously in near future.

  • Gaining an understanding of bird communities in different habitat types is essential for the conservation of ecologically important habitats. Wetlands possess different types of habitats and provide an important environment for wintering waterbird communities. This study compares avian communities in five different habitat types in the Moeyungyi Wetland Wildlife Sanctuary (MWWS), Myanmar. From December 2014 to the first week of February in 2015, bird and habitat data were collected from representative areas of five habitat types (i.e., short grassland, tall grassland, lotus fields, open water areas, and rice fields) at MWWS. We established nine sampling plots in each habitat type, and used the point quadrat method to survey habitats and the point count method to survey birds in the habitats. Simple one-way analysis of variance (ANOVA) and post-hoc tests were used to determine differences between bird communities. We made 95 detections during 19 daily visits to each of the five habitat types. During the survey period, we recorded a total of 10,389 individuals belonging to 52 different bird species, based on 7-min observations at each of the 45 point count stations. Furthermore, we detected significant differences by habitat structure (i.e., vegetation coverage, height, and density; water depth; and plant species diversity) as well as bird communities (i.e., species richness, abundance, and diversity indices). In addition, the detailed analysis of 52 avian species revealed significant differences among 45 species with respect to the mean numbers of observed individuals in the survey habitats. The findings of this study revealed significant differences in the structure and composition of waterbird communities among the five assessed habitat types. Because natural marshes provide preferable habitats for a larger number and greater diversity of birds, relative to rice fields, natural marshes should be prioritized for conservation and restoration in Moeyungyi Wetland Wildlife Sanctuary.

  • This study was conducted to perform efficient conservation and management by classifying the types of wetlands distributed in forests of Korea and assigning grades according to the evaluation system from 2015 until 2019. From 2005 to 2014, 1,264 sites derived from the first national forest wetland survey and 16 additional excavated sites were classified and also evaluated 455 out of a total of 1,280 forest wetlands. Forest wetlands are divided into four types: natural type, abandoned paddy field type, man-made type, and modified type, and by reclassifying them in detail, a total of 11 detailed wetland types could be distinguished. Based on this, evaluation was performed according to various items such as plants and ecology, hydrology and hydrology, humanities and society, and the degree of disturbance was graded. As a result, the forest wetland value was sorted at 30 A- grade sites, high-value B-grade 201 sites, moderate C-grade 184 sites, and low-value D-grade 40 sites. Forest Genetic Resource Reserve (FGRR) and other effective area -based conservation measures (OECMs) were designated for 231 sites that received a high grade of A or B, and a long-term monitoring system should be established to systematically conserve forest biodiversity hotspot. It is judged that wetlands need to be managed more effectively and at the national level.
