In Korea, a cooperation charge on conservation of ecosystem is imposed to prevent indiscriminate development. The total amount of this charge is determined by multiplying the size of the destroyed area by a value per unit area and the area index within 5 billion won. Since 2001, the charge per unit area has been determined to be $250won/m^2$. In this study, we estimated the unit value of ecosystem services per year using benefit transfer method, with a focus on forest resources. According to our results, forest resources have a value of about $3,500won/m^2$ per year. When the non-use value is subtracted, that figure becomes approximately $1,300won/m^2$. If this value incorporates the unit value of the cooperation charge on conservation of ecosystem, it will increase. To comply with the original intent of the cooperation charge on conservation of ecosystem, the fund must be used to improve ecosystem services, including the restoration of a destroyed area or the purchase of new land.

Jeju Special Self-Governing Province has the natural assets resulting in UNESCO World Biosphere Reserve, World Heritage Listed and World Geopark Certification, so the principle of 'Conservation First Development Later' has been set up for the vision of environmental policy to preserve these assets. This case study has been carried out to investigate the realization of the principle of 'Conservation First Development Later' for the development projects performed environmental impact assessment from 1994 to 2012 in Jeju Province, using geographic information systems(GIS). The Jeju Province has its own ordinance to consult and operate an environmental impact assessment(EIA) system. In particular, the conservation area, such as, Absolute/Relative Conservation Area and Underground Water, Ecosystem and View Conservation Zone, has been assigned and managed specially to conserve the natural environment. The 179 projects has been performed EIA for last 18 years in Jeju Province, and then the Absolute Conservation Area has been included in 22 projects and the Relative Conservation Area has been included in 34 projects. However, the 2 projects only have included the Absolute Conservation Area for 7 years after 2005. This result suggests that the application of the principle for the Absolute Conservation Area is strengthened gradually. On the other hand, the 17 projects and the 24 projects have included the Underground Water Conservation Zone assigned grade 1 and 2, respectively, and the number has been increasing after 2004. The results show that it needs to strengthen the application of the principle for this Zone. And the Ecosystem Conservation Zone assigned grade 1 and 2 have been included in 1 project and 9 projects, respectively. It is considered from this result that the principle is realized successfully for the Ecosystem Conservation Zone. In addition, it could be known that the principle is applied well for the View Conservation Zone, in this study.

Korea introduced the cooperation charge on conservation of ecosystem for minimizing damage of ecosystem due to development projects and their effects and for preparing resources for natural environment conservation projects. Advanced countries have made efforts by expanding investment in natural environment conservation and restoring projects to promote prevention of global warming and improvement of biological diversity, are establishing nationwide strategies and plans. To examine the reality of projects by returns of the cooperation charge on conservation of ecosystem, microsite projects in schools and public facilities take the largest share while their project budgets are only about 100~300 KRW, relatively small, which might be attributable to budget restrictions in accordance with the calculating method of levying cooperation charge on conservation of ecosystem and problems of project proceeding in the system of returning fund for projects in general. The conclusion which this study suggests on invigoration of cooperation charge on conservation of ecosystem and its operation are as followings. First, although the cooperation charge on conservation of ecosystem has been introduced in 2001, the amount of imposition per unit area remains unchanged. It is desirable to increase the amount into $1,400KRW/m^2$ as of August, 2011 as the price index has been continuously rising for the past 10 years and the upward adjustment of imposition per unit area should be notified by the decree of the Ministry of Environment every January. Second, the ceiling amount of the cooperation charge on conservation of ecosystem should be abolished. Now the ceiling amount is defined as 1 billion KRW but it was found that there was not any ceiling amount specified according to the comparative analysis of similar systems with the Korean environmental improvement fund. The ceiling should be abolished so that medium level businesses are carried out and ecosystem recovering projects in the true sense of the word can be made smoothly. Third, weight should be introduced in calculating amounts in accordance with ecologic and economic values. Harmony between development and environment can be achieved by applying differentiated weights of constant regional coefficient by use zone and ecologic and economic values. Continuous efforts of improving cooperation charge on conservation of ecosystem should be made more than anything else so that projects by returns of cooperation charge on conservation of ecosystem get effectiveness.

A protected area means a space designated and protected by law from development pressure and environmental pressure. It is mainly designated to protect specific ecosystems, natural landscapes, and cultural resources from irrational development (or damage), and involves policies of the public sector such as central and local governments. The United Nations Educational, Scientific and Cultural Organization (UNESCO) has conducted conservation and restoration projects for preserving natural ecosystems and genetic resources. In order to conserve the ecosystem in the protected area, national and public organizations purchase private land and use it ecologically; in addition, ecological restoration project is carried out for the purpose of creating waterside ecological belt or preserving ecosystem. Land acquisition refers to the land where highly influenced by the water quality and need to restore, and purchased by negotiating with the landlord. Although the nation and public institution carried out ecosystem restoration project for partial purchase land in order to conserve ecosystem, it is below the expected effect due to lack of comprehensive management system and have some problems in restoration project and unification of management institutions. Land acquisition in Donggang River Basin Ecological Conservation area is initiated in 2005 for creating income of local residents and ecological restoration. However, the lack of overall management and awareness resulted in poor vegetation growth and poor response by local residents due to terrain exposure. As such, there is insufficient research on the current situation and systematic integrated management although the number of land acquisition is increasing year after year. Futhermore, overall recognition and follow-up monitoring of eco-restoration are still inadequate. Therefore, the survey on the awareness of the purchase land ecosystem restoration project is necessary for the efficient restoration project and establishment of the management strategy for land acquisition in the future. Therefore, in this study, we provide fundamental materials on further research projects by carrying out research on the awareness of ecological restoration projects in the Donggang River basin ecological preservation area.

This study analyzed and examined literature and legislation in Korean and other countries to examine the concept and sense of mapping of forest functions that would be used as basic information for efficient application and management of forest ecosystems. The mapping of forest functions in Germany has been utilized to field data for efficient work and management of the ecosystem, and evaluation of forest environmental ecology by the mapping of forest functions has been applied directly or indirectly in country management plans, conservation of nature and landscape management plans. Forest protection areas in Korea were analysed for creating a map of forest functions. As the results, forest functions could be sorted into five categories, such as conservation area of forest production, prevention of disasters, landscape and abiological natural resource, valuable biotope and ecosystem and civil recreation. The mapping method was applied to these 5 categories important conservation targets. It is considered that mapping of forest functions in Korea can be used for systematic forest works and efficient ecosystem utilization and management, as well as it use basic data for environmental and ecological comprehension and evaluation on forest and green tract of land on the level of country development and utilization.

This study presents an ecological management plan for wildbird habitat conservation, an nature-friendly enhancement of bio-diversity using the riverside of the Tancheon Ecosystem Conservation Area in Seoul by analyzing environmental and ecological characteristics. As a result of analyzing actual vegetation, vegetation type was classified into 34 types. Humulus japonicus association covers an area of 441,568.6㎡(31.44％), and Artemisia princeps var. orientalis association covers an area of 89,690.1㎡(6.39％). Sandy plain as valuable wildbird habitat covers an area of 89,965.9㎡(6.4％). 125 taxa including 34 families, 93 genera, 107 species, and 18 varieties were recorded and the number of naturalized plants were 41 taxa at the survey site. Total naturalized index(NI) and urbanized index(UI) were recorded as 32.8％, and 15.5％. As a result of analyzing the herb plants association structure by surveying 8 belt-transects, the humid native plants was dominant in the partially adjacent revetment edge and damp riverside. On the other hand, naturalized plants was so extensively dominant that it was necessary to establish an ecological management plan. The observed wildbirds belonged to 50 species, 6,118 individuals, and 7 restricted species by law, which were Accipiter gentilis, Falco tinnunculus, Buteo hemilasius, and Buteo buteo. Oriolus chinensis,Hirundo rustica, and Alcedo atthis. The ecological administration plan for Tancheon Ecosystem Conservation Area as follows: in ecological land-use planning, the conservation area(695,518.5㎡) has native woody and herb vegetation and sandy plain with water as an wildbird habitat. The restoration area(653,702.7㎡) has a naturalized plants distribution are with artificial revetment. The nature-friendly Riverside Area(55,414.9㎡) was an easily approached area with damaged riverside vegetation, and a safe area to wildbird habitat. In riverside restoration planning, the artificial riverside should be restored to its natural riverside vegetation, and the artificial embankment should be restored with edge shrubs for wildbird habitat or revegetated for natural riverside landscape. For naturalized plants management planning, we selected naturalized plant species to be weeded out, and suggested an application method for ecological management.

This research is to apply suitable natural ecosystem evaluation criteria in order to develop the ecosystem conservation, restoration and ways to build substitute habitats as a compensation plan for damaged soundly natural ecosystems in small-scale projects such as resource recovery facility, filtration, etc. The environmental ecology evaluation i.e. generally based on their actual vegetation, community structure, wildlife, water system survey were measured the primary plans for reflecting unique natural environment level of site. As a result, it is necessary to conserve the land in fallow type of wetland, good conservative condition of deciduous forest, wetlanded watercourse for amphibia and reptiles crossing. However, the plan of filtration plant was destroyed wetland(sound ecosystem), natural forest, asian toad spawning area. According to the result of it schemed to build alternative wetland and spawning area, plan to healthy ecosystem and surface soil transplantation as compensation plan. The alternative wetland and spawning area are not only created a various water levels like depth of water is $0{\sim}30cm,\;30{\sim}60cm$, more than 1.5m but also it leads to asian toad spawning and wildlife inhabitant. Moreover, the ecosystem and surface soil transplantation be applied to use the Quercus acutissima forest resources(114 upper trees, 71 canopy trees, 401 shrubs) and surface soil$(5,072m^3)$ in ecology creation sets.

The purpose of this study was to ascertain the prey composition and utilization of the Eurasian otter, Lutra lutra, in the ecosystem conservation region of the Seomjin River. The study was conducted for a 12-month period from March 2003 to February 2004 by spraints analysis and an investigation using artificial holts. We found seasonal variation in the number of spraints and composition of prey items. Fish were the main prey items throughout the period (82%), and other prey items included birds (14%), amphibians (2%) and arthropods (1%). In addition to prey identification, we investigated habitat utilization by otters through spraints distribution. The traces of otters were discovered in five of the six total artificial holts. However, the utilization of the artificial holts in the study area seemed to be limited as evidenced by the low frequency of traces in the holts.
