The Colony of Selaginella involvens (Sw.) Spring in Sanyang-myeon, Mungyeong-si, can be divided into five types, and in the past, it was said that Selaginella involvens (Sw.) Spring formed colonies throughout the colony and grew naturally, but now it remains only in some sections. It was found that the Selaginella involvens (Sw.) Spring colony was damaged by artificial and natural factors, and as an artificial factor, the Selaginella involvens (Sw.) Spring was proven to be effective for medicinal and cremation, and many people were damaging the Selaginella involvens (Sw.) Spring colony without permission. Naturally, vines thrive and Selaginella involvens (Sw.) Spring die, and the reality is that the entire colony of Selaginella involvens (Sw.) Spring is in danger of being damaged if maintenance is not performed. On the other hand, there are sections that reproduce with symbiosis with some herbaceous plants, so it is necessary to plan and implement conservation strategies. In order to preserve the Selaginella involvens (Sw.) Spring colony, CCTV is needed to prevent artificial damage, and on the contrary, install facilities such as fences can easily burn up and create worse scenery, so it can preserve the good environment, restore recoverable areas, and install supplementary buffer zones.

Payment for Ecosystem Services (PES) is emphasized to enhance ecosystem conservation and increase its ecological value. However, effective implementation of PES and policy execution requires insufficient ecosystem monitoring and research. Therefore, this study analyzed the effectiveness of PES implemented in Janghang Wetland to propose habitat management strategies. The study included monitoring migratory birds and analyzing key species' food sources. The dominant avian species observed in Janghang Wetland include Larus crassirostris, Anas platyrhynchos, Anser albifrons with their primary food sources analyzed as Gramineae plants such as Bromus japonicus, Elymus sibiricus, Brassicaceae plants such as Rorippa palustris. Furthermore, this study found that PES facilitates rice seed supply within Janghang Wetland, benefiting birds including Grus vipio, Anser fabalis, A. albifrons. To sustainable manage Janghang Wetland, improving food supply systems and exploring decentralized supply methods for G. vipio and Gooses (Anser fabalis, A. albifrons) are necessary. Additionally, managing boundaries between agricultural and developmental areas to improve ecological connectivity is essential. This study reaffirmed the ecological importance of Janghang Wetland as a crucial habitat for migratory species. The result will be significant as foundational data that can be used for future policy-making and support sustainable conservation efforts.

The number of visitors to historic sites and museums in Korea has been on a rapid decrease and in order to search for creative ways to work on the problem, the study proposed a theme park-typed museum with cultural heritage applied and reviewed spatial strategies for such theme park-typed museums. Applied methods of research of this study are as follows. First, in order to understand definitions and current situations of cultural heritage use and theme park-typed museums, the study went thoroughly over all sorts of literature and reports as well as findings of advance researches on how to make a use of cultural heritage. Based on the results of the investigations, the study determined characteristics of the theme park-typed museums with cultural heritage applied which the study was proposing and the characteristics were categorized by type. Considering those characteristics and types gained in the study, the study looked for cultural heritage-based theme parks and museums in the world which were good enough to be used as research subjects in the study from the aspects of profitability and level of awareness. The study examined those theme parks and museums in the world and in the end, it found out ways to adopt the findings to the situations in Korea and discussed expecting effects as well. As to the characteristics of the theme park-typed museums with cultural heritage applied, the study divided those characteristics into mutual cooperation, location, communicability, authenticity, maintainability, education, durability, narrativity, undailiness, interactivity and leisure. The types were categorized into ride, environment direction, cartoon character and souvenir by attraction pattern. When cultural heritage is used actively, it would improve competitiveness of historic cultural sites and museums in return, making people realize the iterative structure of excavation, conservation, maintenance and use of cultural heritage. That would create many kinds of added values, re-discovering culture of the country. At the same time, it would also create a new value of culture as well. Now, it is important for us to do harder with researches on how to evolve museums and exhibition spaces. Considering that, the study is believed to make a contribution to revival of historic sites and museums in Korea but also establishment of scientific strategies.

As climate changes, it is necessary to predict changes in the habitat environment in order to establish more aggressive adaptation strategies. The bioclimatic classification which clusters of areas with similar habitats can provide a useful ecosystem management framework. Therefore, in this study, biological habitat environment of Northeast Asia was identified through the establishment of the bioclimatic zones, and the impac of climate change on the biological habitat was analyzed. An ISODATA clustering was used to classify Northeast Asia (NEA)into 15 bioclimatic zones, and climate change impacts were predicted by projecting the future spatial distribution of bioclimatic zones based upon an ensemble of 17 GCMs across RCP4.5 and 8.5 scenarios for 2050s, and 2070s. Results demonstrated that significant changes in bioclimatic conditions can be expected throughout the NEA by 2050s and 2070s. The overall zones moved upward, and some zones were predicted to be greatly expanded or shrunk where we suggested as regions requiring intensive management. This analysis provides the basis for understanding potential impacts of climate change on biodiversity and ecosystem. Also, this could be used more effectively to support decision making on climate change adaptation.

Climate change induced by global warming has recently begun to inspire developed nations to introduce a new paradigm, called the sustainable (Green) growth, which entails both the prevention of environmental pollution and the attainment of sustainable growth. The sustainable (Green) growth is founded upon environmental factors that drive a new force of economic progress without deteriorating nature. Thus, the conservation of the environment under the new growth paradigm can be compatible with economic growth, although this was not feasible under conventional economic relations, called the Environmental Kutzets Curve. Sustainable (Green) finance is essential to achieving Green growth efficiently and effectively. Since the financial system for Green growth is at the early stage of implementation, the application of strategies for sustainable (Green) finance should be preceded by proper initiation and protection from the government. In order to establish a feasible strategy for financing green growth, we suggest an effective financial supporting system, taking different operational forms upon the broader stage of technological progress in each individual company.

This study investigated some of the specific ecological characteristics Torreya nucifera forest and its health conditions so that was drawn from four different management strategies, such as Types A, B, C, and D, for protected areas of forest genetic resources. Type A refers to passive management which routinely keeps the current status of forests by removing competitive trees or curing damaged ones. Type B, as active one which improves Torreya nucifera forest, includes increase of soil pH and removal of Sasa borealis, Phyllostachys bambusoides, and deciduous broad-leaved trees such as Quercus variabilis, Carpinus tschonoskii et al.. Type C is another passive one which reduces soil acidity within Chamae cyparisobtusa forest and maintains the existing forests. Type D is another active one which decreases soil acidity and simultaneously reduces problems associated with competitive and invasive plants to nurture the young trees. At last, it is important to note that the protected areas for forest genetic resources need to be entitled to categories III(natural monument) or IV(habitat/species management area) in accordance with protected area management guidelines of IUCN.

Glaux maritima var. obtusifolia is distributed in very limited areas in South Korea and thus designated and protected as an endangered species. This study aimed to identify the diversity of vegetation in the Dangsa coast wetlands, the southern limit of G. maritima var. obtusifolia and to assess determinants of the vegetation and the importance of habitats. The phytosociological method of the $Z{\ddot{u}}rich-Montpellier$ School was used for vegetation classification and mathematical and statistical analyses were also conducted to analyze environmental factors and their relationship with the vegetation. The results of this study showed that there were 4 vegetation units in the Dangsa coast wetlands: Glaux maritima var. obtusifolia-Triglochin maritimum community (included three subcommunities), Puccinellia nipponica s.l. community, Beckmannia syzigachne-Isachne globosa community and Typha laxmannii-Phragmites communis community. It was also found that major determinants of the vegetation include moisture environment, soil depth, water level disturbance, vegetation height, community structure, etc. Glaux maritima was identified to grow most dominantly in the typicum subassociation of Glaux. maritima var. obtusifolia-Triglochin maritimum community, and the species compositions and dominant situations were observed to be similar to those in the southern limit in Japan, adjacent to South Korea. The assessment results indicated that the Dangsa coastal wetlands have a significant meaning from phytogeographical and syngeographical aspects, and contribute as a shelter for diverse species. It is required to establish conservation strategies to accurately determine the value of the wetlands of the Dangsa coast from various perspectives, and to protect and manage them.

Objective: At least eight local duck breeds have been recognized and documented as national germplasm of Indonesia so far. It is necessary to genetically characterize the local duck breeds for aiding conservation and future improvement strategies. Thus, this study was carried out to assess genetic diversity and phylogenetic relationship of eight local duck populations of Indonesia using microsatellite markers. Methods: In total, 240 individuals (30 individuals each population) from Alabio (AL), Bayang (BY), Magelang (MG), Mojosari (MJ), Pegagan (PG), Pitalah (PT), Rambon (RM), and Turi (TR) duck populations were genotyped using 22 microsatellite markers. Results: The results showed a moderate level of genetic diversity among populations, with a total of 153 alleles detected over all loci and populations, ranging from 3 to 22 alleles per locus. Observed (Ho) and expected heterozygosity (He), as well as polymorphism information content over all loci and populations were 0.440, 0.566, and 0.513, respectively. Heterozygote deficiency in the overall populations ($F_{IT}=0.237$), was partly due to the heterozygote deficiency within populations ($F_{IS}=0.114$) and moderate level of genetic differentiation among populations ($F_{ST}=0.137$). The most diverse population was MG (He = 0.545) and the least diverse population was AL (He = 0.368). The majority of populations were relatively in heterozygote deficiency (except AL), due to inbreeding. The genetic distances, phylogenetic trees, and principal coordinates analysis concluded that the populations can be grouped into two major clusters, resulting AL, MG, and MJ in one cluster separated from the remaining populations. Conclusion: The present study revealed a considerable genetic diversity of studied populations and thus, proper management strategies should be applied to preserve genetic diversity and prevent loss of alleles.

As urban heat environment problems occur due to climate change, urban thermal environmental problems such as heat waves and tropical nights are becoming more serious in cities. In South Korea, forest areas favorable for generating cold air account for about 63 percent of the land area. Furthermore, the Jeongmaek, the axis of the main mountain ranges of Korea, is located close to the cities. Hence, the management of cold air is an effective way to improve the thermal environment of Korean cities. We selected the Nak-nam Jeongmaek located in the southern part of Korean Peninsular as well as two cities (Jinju-si and Sancheong-gun) located at the Jeongmaek to analyze its cold air characteristics and suggest management strategies of cold air. We used KALM (Kaltluftabflussmodell), a cold air simulation model developed in Germany and identified both the cold air flow and the height of cold air layer generated during 6 hours at night. As a result, the cold air flow generated in the Jeongmaek became clear and the height of cold air layer increased with time. Based on the results, we proposed management plans to maintain and expand the cold air flow. For example, forest areas with active cold air generation were designated as 'cold air conservation areas', and areas requiring management for good cold air flow were as 'cold air management areas'. This study is expected to be useful for establishing systematic urban ventilation plan to improve thermal environment in Korea cities.

This study conducted an analysis of terrain change indicators in major development projects in Korea, examining the correlation between terrain change indicators to derive foundational terrain change metrics based on different land use and slope types. The aim is to contribute to sustainable development by enhancing the efficiency of land utilization and landscaping, while minimizing environmental impacts in future development endeavors. Additionally, to apply the research findings in practical contexts, domestic regulations related to terrain were surveyed, and the compatibility and usability between these regulations and research analysis results were discussed. Based on this, the study seeks to explore strategies for more accurate and useful utilization of terrain change indicators in future research. As a result, in the tourism development, terrain changes predominantly occur in the order of flat land, hillly land, and mountain land, with the analysis indicating higher terrain changes in undulating hilly and mountainous lands compared to flat land. Furthermore, in industrial complex development, very steep (20°-30°) and extreme (30°-40°) slopes; in urban development projects, steep slope (15°-20°); in athletic service facility and tourist development, steep (15°-20°) and very steep (20°-30°) exhibit higher average terrain change indicators compared to other slope categories. The findings of our study can contribute to the formulation of strategies aimed at minimizing terrain disturbance in future domestic development projects and serve as foundational data for environmental impact assessments.
