Recently, a number of local governments as well as private organizations have spearheaded the release of animals into the natural ecosystem in Korea. In 2002, most of these animals released were mammals and birds, but the parameter was gradually expanded to include fish, amphibians, and invertebrates in addition to mammals and birds in 2007, with an increased overall number of animals released. Such increase has not only posed ecological, economic, and public health risks, but also yielded an increase in damages incurred by releasing animals historically or ecologically alien to a given region without thorough risk assessment. The most significant cause of such risks was a critical lack of risk management and regulatory schemes addressing the release of animals into the natural ecosystem. In stark contrast, developed countries long before established the requisite risk management and regulatory schemes either by complying with the IUCN/SSC's Guidelines for Re-Introductions or devising them independently. In this context, the current study has examined the release of animals into the natural ecosystem in Korea and, based on the investigation, asserted a strong need for proper risk management. Moreover, the study has presented systematic risk management and regulatory schemes suitable for the Korean milieu based on a comparative analysis of those employed in developed countries.

Climate change caused by increased greenhouse gas emissions can alter the natural ecosystem, including the pollination ecosystem and agricultural ecology, which are ecological interactions between potted insects and plants. Many studies have reported that populations of wild bees, including bees and wasps (BW), which are the key pollinators, have gradually declined due to climate change, leading to adverse impacts on overall biodiversity, ultimately with agribusinesses and the life cycle of flowering plants. Therefore, we could infer that the rising temperature in Korean Peninsula (South Korea) due to global warming has led to climate change and influenced the wild bee's ecosystem. In this study, we surveyed the distributional pattern of BW (Superfamily: Apoidea, Vespoidea, and Chrysidoidea) at 51 sites from 2017 (37 sites) to 2018 (14 sites) to examine the effects of climatic factors on the nationwide distribution of BW in South Korea. Previous literature has confirmed that their distribution according to forest climate zones is significantly correlated with mean and accumulative temperatures. Based on the result, we predicted the effects of future climate changes on the BW distribution that appeared throughout South Korea and the species that appeared in specific climate zones using Shared Socioeconomic Pathways (SSPs). The distributions of wild BW predicted by the SSP scenarios 2-4.5 and 5-8.5 according to the BIOMOD species distribution model revealed that common and endemic species will shift northward from the current habitat distribution by 2050 and 2100, respectively. Our study implies that climate change and its detrimental effect on the ecosystem is ongoing as the BW distribution in South Korea can change, causing the change in the ecosystem in the Korean Peninsula. Therefore, immediate efforts to mitigate greenhouse gas emissions are warranted. We hope the findings of this study can inspire further research on the effects of climate change on pollination services and serve as the reference for making agricultural policy and BW conservation strategy

It is widely recognized that destruction of the eco-system with the counter-effect from the rapid industrialization threatens the life of human species. Furthermore, the extinction of some wild species keeps sending a warning message on the threat to human lives in the sense that both the human and wild lives have coexisted for a long time before the industrialization. Therefore, this study will shed a light on the importance of a natural ecology protection, focusing on wild-life conservation. This will provide an opportunity to consider the economic value of biodiversity through conservation of diverse wild lives and a natural ecology. Also, the irreversible damage to natural resources and extinction of certain species represent the urgency of this issue. This paper will perform a theoretical examination on the concept of wild plants and animals, an analysis of factors influencing their survivals, as well as the theory of natural ecology protections. This also examine the problems arising out of current domestic legislation of a natural ecology protection, comparing it with case studies of foreign countries. Through these analysis, this paper will seek for a maintenance of the currently enforcing natural ecology protection law to overcome its limits and will ultimately find alternatives to current system.

Within the scope that does not interfere with the performance of basic duty, the military has been actively supporting the national policy for the conservation of the natural environment in accordance with the "military environmental protection guidelines". Since there is a lack of information regarding inhabitation for wild fauna and flora, field investigations of the natural environment at Jinhae local unit were performed three times in 2003. As a result of the investigation, lycoris sanguinea as flora, marten, otter, and leopard cat as mammalia, and accipiter soloensis, accipiter gentilis schvedow, accipiter gularis, buteo hemilasius, falco tinnunculus and terpsiphone atrocaudata as bird were confirmed to inhabit. For the conservation of the natural ecosystem, the expansion of research for natural ecosystems within the military unit is required. Additionally, environmental pollution can be prevented through the proper maintenance of basic environmental facilities including sewage treatment facilities, soil pollution control facilities, and waste storage facilities. In cooperation with local governments and private organizations, the natural cleansing action and sustainable wildlife conservation should be expanded.

The wetland ecosystem is a complex products of various erosion force, accumulation as water flows, hydrogeomorphic units, seasonal changes, the amount of rainfalls, and other essential element. There is no single, correct, ecologically sound definition for wetlands because of the diversity of wetlands and the demarcation between dry and wet environments occurs along a continuum, but wetland plays various ecosystem functions. Despite comprehensive integration through classification and impact factors there is still lacking in systematic management of wetlands. Classification system developed by the USFWS(1979) is hierarchical progresses from systems and subsystems at general levels to classes, subclasses, dominance types, and habitat modifiers. Systems and subsystems are delineated according to major physical attributes such as tidal flushing, ocean-derived salts, and the energy of flowing water or waves. Classes and subclasses describe the type of substrate and habitat or the physiognomy of the vegetation or faunal assemblage. Wetland classes are divided into physical types and biotic types. For the wise management of wetlands in Korea, this study was carried out to examine methodology of USFWS classification system and discuss its application for Korean wetland hydrogeomorphic units already known. Seven wetland types were chosen as study sites in Korea divided into some different types based on USFWS system. Three wetland types belonging to palustrine system showed no difference between Wangdungjae wetland and Mujechi wetland, but Youngnup of Mt. Daeam was different from the former two types at the level of dominant types. This fact means that setting of classification system for management of wetland is needed. Although we may never know much about the wetland resources that have been lost, there are opportunities to conserve the riches that remain. Extensive inventory of all wetland types and documentation of their ecosystem functions are vital. Unique and vulnerable examples in particular need to be identified and protected. Furthermore, a framework with which to demonstrate wetland characteristics and relationships is needed that is sufficiently detailed to achieve the identification of the integrity and salient features of an enormous range of wetland types.

The objective of this study was to evaluate biodiversity and natural habitat environment of freshwater ecosystem. Our aim was therefore to produce a set of biodiversity and habitat indicators based on multi-parameters of water quality and biodiversity by analyzing the characteristics of the results by indicators. We selected four indicators a) anthropogenic disturbance, b) habitat diversity, c) biodiversity, d) ecosystem structure. The fishes cohabiting with Brachymystax lenok tsinlingensis were Rhynchocypris kumgangensis and Zacco koreanus. As a result of the anthropogenic disturbance evaluation, it was analyzed that vegetation embankment showed a more stable environment in the tributary than the main stream, and other disturbance was not confirmed As a result of the habitat diversity evaluation, it was analyzed that habitat evaluation index showed a high score of 200 more on average, showing an optimal habitat condition. As a result of the biodiversity evaluation, it was analyzed as a clean habitat condition with a high proportion of sensitive species, abundant dissolved oxygen, and little pollutants. As a results of the ecosystem structure, the ecological health condition metrics and appearance of endangered species showed large score deviation, but it was analyzed that the stream ecosystem health was generally excellent. There was a slight correlation between the habitat environment and the results of the nature habitat evaluation according to the appearance of the B. lenok tsinlingensis.

The purpose of this study was to find the changes in the habitat of wild birds caused by climate change in urban rivers and protected areas that greatly require ecological functions. In the future, this study can be used as a management index to protect the urban river ecosystem and maintain the health of sustainable urban rivers, thereby ensuring biodiversity. The Tancheon Ecological and Landscape Conservation Area, selected as a target site, has been affected by climate change. The four seasons of Korea have a distinct temperate climate, but the average annual temperature in Seoul has risen by 2.4-2.8℃ over the last 40 years. Winter temperatures tended to gradually increase. Precipitation, which was concentrated from June to August, is now changing into localized torrential rain and a uniform precipitation pattern of several months. Climate change causes irregular and unforeseen features. Climate change has been shown to have various effects on urban river ecosystems. The decrease in the area of water surface and sedimentary land impacted river shape change and has led to large-scale terrestrialization. Plants showed disturbance, and the vegetation was simplified. The emergence of national climate change indicator species, the development of foreign herbaceous plants, the change of dry land native herbaceous species, and wet intelligence vegetation were developed. Wild birds appeared in the territory of winter-summer migratory. In addition, species change and the populations of migratory birds also occurred. It was judged that fluctuations in temperature and precipitation and non-predictive characteristics affect the hydrological environment, plant ecology, and wild birds connecting with the river ecosystem. The results of this study were to analyze how climate change affects the habitat of wild birds and to develop a management index for river ecological and landscape conservation areas where environmental and ecological functions in cities operate. This study can serve as a basic study at the level of ecosystem services to improve the health of urban rivers and create a foundation for biodiversity.
