Twenty-eight of 44 Indian Ceropegia species are endemic and their survival is threatened. As a step towards conservation, we implied in vitro methods for the sustainable propagule production in C. hirsuta, C. lawii, C. maccannii, C. oculata and C. sahyadrica. Effects of explant, growth regulators, sucrose and photoperiod were studied. High frequency microtuber production was achieved with the seedling-apical buds, grown on MS medium containing 4-6 mg $1^{-1}$ BAP, 3-8% (w/v) sucrose, under continuous illumination. Each microtuber, when subcultured proliferated to form a cluster of secondary microtubers. Every primary and secondary microtuber bore at least one shoot-bud and a root primordium. Each tuber (formed with any of the significantly effective treatments) weighed more than 500 mg, enough to plant directly in non-sterilized soils. Microtubers could be produced and proliferated round the year. Proliferation could be solely attributed to in vitro procedures as these plants bear solitary tubers in vivo. Microtubers could be sprouted in vitro to prepare ready to pot plantlets. As, this novel method succeeded for all five species, though they belong to different eco-physiological backgrounds, we recommend its implementation in the conservation programs for a broader range of Ceropegia species, supported by other integrated strategies.

주왕산 국립공원의 자연보존지구를 중심으로 분포하고 있는 천연림의 생육현황과 구조를 정확히 파악하고자, 이 지역에 21개의 방형구(20$\times$20m)를 설치하여 식생을 조사하였다. Cluster 분석한 결과 두 개의 집단으로 분류되었다. 수종간의 상관관계는 서어나무와 물푸레나무, 졸참나무와 굴참나무, 생강나무와 국수나무 등의 수종들 간에는 비교적 높은 정의 상관관계를, 고로쇠나무와 쇠물푸레, 당단풍과 굴참나무 둥의 수종들 간에는 높은 부의 상관관계를 보였다. 본 조사지의 종다양도는 1.1306~l.2688로 비교적 높게 나타났다.

To respond to rapidly changing water circumstances such as climate change, drought, etc., the korean government (MOE) established four advanced strategies for integrated groundwater management. The first strategy is watershed-based management of groundwater. The second strategy is total quantity management of groundwater including improvement of groundwater preservation area policy and procedure of investigation for groundwater influence area, additional construction of groundwater dam, installation of large-scale public wells, extention of spilled groundwater use. The third strategy is prevention of groundwater contamination including expansion of monitoring wells, introducing declaration of groundwater contamination. The last strategy is advancement of groundwater information management including integrated management of data, setting up a big-data based open platform. The above-mentioned four strategies will be reflected in the 4th National Groundwater Management Plan to secure implementation power, and it is expected to laid the foundation for advanced and rational groundwater management system.

한반도 특산식물인 매미꽃 자생 집단의 보전대책 수립을 위한 기초자료로 활용하고자 자생 집단의 분포와 식생환경 및 보전지위 평가를 수행하였다. 문헌자료 및 표본정보 수집과 현지조사를 통해 분포도를 작성한 결과 매미꽃은 지리산과 백운산 등 경상남도와 전라남도를 중심으로 주로 한반도 남부지방에 집중 분포하는 것으로 확인되었다. 또한 자생 집단은 주로 해발 227~744 m의 범위에 분포하였으며, 경사는 $5{\sim}11^{\circ}$ 계곡의 중 하부 지역에 많이 분포하였다. 8개 자생 집단에 대한 식생조사 결과 29개 조사구에서 총 238분류군이 출현하였으며, 각 조사구 내 초본층의 피도와 빈도를 기초로 매미꽃의 중요치를 산출한 결과 평균 25.34%로 나타났다. 8개 집단 내에 출현 종의 다양도는 평균 1.52였으며, 균등도와 우점도의 평균은 각각 0.83과 0.17로 산출되었다. 수집된 생물학적 자료를 바탕으로 IUCN 적색목록 기준에 의한 보전 지위를 평가한 결과 매미꽃은 Near Threatened(준위협종)에 포함되는 것으로 나타났으며, 이에 따라 매미꽃 자생 집단의 지속가능한 보존을 위한 전략수립과 필수적인 기초연구의 내용 및 방법이 논의 되었다.

국가 생물다양성 전략에 따른 보호지역의 확대는 생물다양성 보전에 기여하는 반면에 지역주민들에게 다양한 경제적 피해를 발생시킨다. 이에 보호지역 지정으로 인한 지역주민의 피해를 보상할 수 있는 지속가능한 방안으로서 생태계서비스지불제의 필요성이 제기되었다. 이 연구에서는 보호지역의 확대를 통한 생물다양성 보전으로부터 국민들이 얻는 편익을 추정하여 생태계서비스지불제의 시행가능성을 검토하기 위해 지리산 방문객을 대상으로 CVM을 이용하여 지리산의 생물다양성 보전에 대한 지불의사액을 추정하였다. 방문객들은 생태경관보전지역을 확대하여 지리산의 생물다양성을 증진시키는 데 연간 가구당 16,103원의 지불의사가 있는 것으로 나타났고, 이를 전체 가구로 확대한 지리산 생물다양성의 총 보전가치는 연간 3,168억 원으로 추정되었다. 방문객들은 연령, 교육수준, 가구소득이 높을수록, 지리산이 생태경관보전지역으로 지정되어 있다는 사실을 사전에 인지한 경우, 생물다양성 보전 정책이 중요하다고 생각할수록 생물다양성 보전에 대한 지불의사가 있는 것으로 나타났다. 이에 생태계서비스지불제의 시행가능성을 높이기 위해서는 생물다양성 교육과 정책 홍보를 통해 국민들의 생물다양성에 대한 지식과 인식을 높이는 것이 필요하다.

Korean fisheries industry is surrounding by domestic and international difficulties due to the effectuation of the UN Convention on the Law of the Sea and declaration by many coastal states of 200-mile Exclusive Economic Zone and acceleration of ocean pollution in global recognition increasing of the importance of the ocean Resource enhancement policy in Korea fisheries industry is very important strategy fer the fostering of the fisheries resource and proper conservation and management of the coastal and off-shore living marine. Among resource enhancement policy, artificial reefs project has been the most effective strategy. The objectives of this paper are to find the economic effects of artificial reefs. The sampling artificial reefs is constructed at Suiido with 6~7m height. In order to analyze the fishing effect of artificial reefs, a few research have been conducted since 1975. For these analysis focuses on the side of scientific effect of artificial reefs, we analyzed on the side of economic effect. The results of the economic effects of artificial reefs are as follows ; First, the fishing effect analysis by using the NPV method in artificial reefs of Suiido ground prove to be economic feasibility. Second, the major socio-economic effect from artificial reefs include the increasing of recreation fishing, maintenance of fishing community, protection illegal fishing, conservation of coastal environment, and enlargement of advanced fisheries supply. Based on the above results, we conclude that artificial reefs project not only contributes to the welfare of fishermen by increasing of economic income, but enlarges to socio-economic gains by protection of illegal fishing and conservation coastal environment and so on.

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.
