This study aims to establish operating methods for value-oriented and competitive operation of Dalseong Wetland Ecological Learning Center in Daegu, Korea, which will open in 2018. For this purpose, we surveyed 77 Ecological learning facility managers nationwide using 22 questions on the subjects such as the operating method, volunteer, budget, and profit. The managers of 50 ecological learning facilities (Type A) responded, and we extracted the responses by the managers of 12 ecological learning facilities (Type B) that had the similar size as the Dalseong Wetland Ecological Learning Center and conducted an additional analysis. The results of the survey indicated that it was advisable for Daegu Metropolitan City to operate the Dalseong Wetland Ecological Learning Center and that the staff at least 3-5 managers were necessary while the number of volunteers to regularly work at the center was estimated to be 25-30. Excluding labor costs, the annual operating budget was estimated to be between 150 million won and 200 million won if Daegu Metropolitan City operates the facility directly. This study is meaningful in that it provides reference data to establish realistic and detailed management plan of the Dalseong Wetland Ecological Learning Center based on the opinions of the surveyed managers of ecological learning facilities in Korea.

The major causes of environmental and social conflicts were analyzed through the samples of the construction and the management for tidal power plant abroad and inland. Based on the results, the eco-friendly and socially acceptable policy instruments for decreasing the scope and intensity of the conflicts were explored. Regarding environment issues, it was found that the tidal power project resulted in decreasing in tidal range and area of intertidal zone and in damaging to tidal flat and wetland conservation area. Also there are the characteristic change of tidal current and biological effect, etc. The major environmental and social conflicts were resulted from the distrust of environmental results to environmental impact assessment and prior environmental review and the distrust of project feasibility study, and insufficient activities of public participation. In this study, introduction to joint fact-finding(JFF) was reviewed as the measure of minimizing environmental and social conflicts.

This study conducted a classification of small-scale biological habitats created in Seoul to analyze and synthesize location characteristics, habitat structure, biological habitat functions, and threat factors of representative sites, as well as derive creation and management problems according to the ecological characteristics. The aim was to suggest improvement measures and management items. Data collected through a field survey was used to categorize 39 locations, and 8 representative sites were selected by dividing them into location, water system, and size as classification criteria for typification. Due to the characteristics of each type, the site was created in an area where amphibian movement was disadvantageous due to low or disconnected connectivity with the hinterland forest, and the water supply was unstable in securing a constant flow and maintaining a constant water depth. The habitat structure has a small area, an artificial habitat structure that is unfavorable for amphibians, having the possibility of sediment inflow, and damage to the revetment area. The biological habitat function is a lack of wetland plants and the distribution of naturalized grasses, and threats include the establishment of hiking trails and decks in the surrounding area. Artificial disturbances occur adjacent to facilities. When creating habitats according to the characteristics of each type, it was necessary to review the possibility of an artificial water supply and introduce a water system with a continuous flow in order to connect the hinterland forest for amphibian movement and locate it in a place where water supply is possible. The habitat structure should be as large as possible, or several small-scale habitats should be connected to create a natural waterfront structure. In addition, additional wetland plants should be introduced to provide shelter for amphibians, and facilities such as walking paths should be installed in areas other than migration routes to prevent artificial disturbances. After construction, the management plan is to maintain various water depths for amphibians to inhabit and spawn, stabilize slopes due to sediment inflow, repair damage to revetments, and remove organic matter deposits to secure natural grasses and open water. Artificial management should be minimized. This study proposed improvement measures to improve the function of biological habitats through the analysis of problems with previously applied techniques, and based on this, in the future, small-scale biological habitat spaces suitable for the urban environment can be created for local governments that want to create small-scale biological habitat spaces, including Seoul City. It is significant in that it can provide management plans.

Invasive species are organisms that are introduced into places outside of their natural distribution range. The global pet trade is facilitating the introduction of invasive species into new countries and areas. Among the introduced alien species, turtles are one of the most common animal groups whether lives in wetland ecosystems, such as wetlands or reservoirs. Like other countries around the world, exotic turtles is becoming a growing concern for the wetland ecosystem in South Korea. In this study, we report new reports of subspecies of Painted turtle (Chrysemysspp.): Chrysemys picta marginata, C. p. bellii and C. dorsalis, from the reservoirs in downtown Cheongju and Gwangju, South Korea. We used morphological features, such as the characteristics of the legs, plastron, and carapace, to identify the turtles. It is assumed that all turtles were artificially released into nature. Considering the increasing number of reports on the introduction of alien invasive turtles in Korean wetlands, we recommend the formulation of an immediate and systematic management plan for pet trades and organized continuous monitoring programs.

Changpo Lake was created as a part of a land reclamation for refugee self-helping projects. It shows characteristics of a fresh water lake, and still retains the early appearance of reclamation that surrounding regions have not been developed into farm lands. Shallow wetland has formed around the lake, which provides great conditions for diverse lives, and surrounding earthiness is favorable for growth of vegetation and restoration of the ecosystem. However, as facilities of the Muan International Airport nearby Changpo Lake are expanding and barns are being constructed, artificialness is gradually increasing. Particularly, since pollution sources such as sport facilities, farm lands and barns are scattered around Changpo Lake, pollutants are flowing in constantly. Accordingly, the results for setting up management areas according to the spatial characteristics and creating natural ecological spaces near Changpo Lake, Taebongcheon stream and Hakgyecheon stream are as follows. First, the creation of a natural eco-friendly waterfront space should be promoted by securing the health of the aquatic ecosystem and restoring species and the ecosystem. In addition, a consultative body needs to be formed to lead local residents to participating in river investigation and monitoring, maintenance, and management through role sharing. Second, the basic direction of the spatial management plan is to keep the unique charm of Changpo Lake, maintain harmony with nature, create diverse waterfront areas, and secure the continuity of Changpo Lake and inflow streams. Moreover, the area should be divided into three zones such as a conservation zone, a restoration zone and a waterfront zone, and for each zone, the preservation of vegetation, the creation of ecological wetlands and restoration of the ecotone and ecological nature need to be promoted. Third, facilities and activity programs for each space of Changpo Lake should be operated for efficient management of protected areas. In order to suit the status of each space, biological habitats, water purification spaces, experiential and learning spaces, and convenience and rest spaces should be organized and designated as research, monitoring, education, and tourism areas. Accordingly, points of interest should be set up within the corresponding area. In this study, there are many parts that need to be supplemented for immediate implementation since the detailed plans and project costs for the promotion of programs by area are not calculated. Therefore, it is necessary to make detailed project plans and consider related projects such as water quality, restoration of habitats, nature learning and observation, and experience of ecological environments based on the categories such as research, monitoring, education and tourism in the future.

'Planning researchers' believe that losses from floods can be reduced if governments address this issue and adopt appropriate policies in their plan. As a starting point for examining this idea, this research assessed the ability of local government to incorporate flood mitigation policies in their local comprehensive plans using plan quality evaluation methodology. This study analyzed 53 local comprehensive plans in Florida against the protocol developed by including key flood mitigation policies. While flood mitigation through land use management tools, such as permitted land use in floodplain areas and wetland permit, gained widespread acceptance at the local level in Florida, incentive based tools/taxing tools and acquisition tools were rarely adopted. Study results show that 53 local plans in the sample received a mean score for total flood mitigation policy quality of 38.55, which represents 35.69 % of the total possible points. These findings indicate that there is still considerable room for improvement by local governments on flood issues. The scores of local plans varied widely, with coastal communities receiving significantly higher scores than non-coastal communities. Because the concept of the plan quality and its methodology offer an objective and straightforward tool for studying plan quality and guiding plan preparation, they can be applied to various environmental and hazard issues in Korea.

This study is aimed at using the grasped problems of protected areas in Korea as the basic data for management planning and system improvement of protected areas by grasping realistic problems through the interview with the persons in charge on the basis of general problems of domestic protected areas. To this end, this study deducted major problems in urgent need of improvement, and improvement direction through the survey of the persons in charge of protected areas. This study result is as follows: The major problems, which should be preferentially improved, were found to be shortages of management infrastructure, cooperation between interested parties, and threat factors in protected areas, etc. Such problems are interconnected with each other, thus coming up complexly; therefore, it's necessary to make a comprehensive approach to the problems after confirming the causal relationship of the identified problems. In addition, for the purpose of effective management of a protected area, it's necessary to implement priority management of major problems through different management intensity from the planning phase. Also, it's important to enhance the effectiveness of planning by considering a possible potential threat factor in the outside of protected areas, and referring to the contents of the development plan for the relevant area in time of management planning. Lastly, there is the need for systematic improvement of an institution through thorough status review of the actual state of management planning fulfillment in order to increase the effectiveness of planning in a follow-up study hereafter.

An eco-washland is increasingly getting attentions as a new alternative plan for management of water resources because of role as flooding control and ecological park without social and ecological side effects. However, there is a lack of study regarding technological development and ecological guidelines to create eco-washland. This study was carried out to suggest ecological guidelines necessary for engineering process to create eco-washland. A study site was the lower reach of Seokjang stream connecting to Yimjin river, a candidate of new eco-washland, and Kumsa area in Namhan river was selected as a reference site. The analysis of ecological characteristics focused on vegetation, fishes, and birds. Major vegetation communities, composed of dominant species such as Salix koreensis, Salix gracylistyla, Miscanthus sacchariflorus, Phragmites communis, etc., formed physical conditions along with other land uses including open water, sandbar, cultivated land, etc. Dominant species of fishes were some species belonging to Cyprinidae and Acheilognathinae, and in case of birds Anser albifrons, Anas platyrhychos, Anas poecilorhyncha belonging to waterbirds and Paradoxornis webbinanus dependent to forest edge were dominantly distributed. The results showed that complex wetland types associated with partially deep water and upland was the optimal eco-hydrological condition of washland. Cyprinidae and Acheilognathinae in case of fish and Egretta spp. (spring season) and Anas spp. (winter season) in case of bird were selected as target species for the these wetland types. Finally, a detail planning criteria to create habitats of these target species were discussed in terms of spawning, breeding, feeding, resting, refuge, nesting, etc.
