Biodiversity in Korea and in East Asia LEE Byung-Hoon Abstract: 1 Introduction The Korean peninsula covers 221,125 km2 in area. mostly alpine, more than 70% of the land occupied by mountains. It extends roughly 1,000 km long and 216 km wide at its narrowest point, harboring mountain ranges, watersheds, valleys, lakes and rivers throughout the country. In South Korea forests comprise 6,456,000 hectares, almost 65% of 996,000 Km of the area. Continental shelf including tidal zones, in addition, as large as 360,000 ha, is almost three times the area of South Korea, surrounded by the seas in East, West and South [1]. The Korean biota, however, consists of only 28,462 species on record, including 4,662 higher plants, 3,609 lower plants and about 16,663 animal species in 20 phyla including 736 protozoan species (Table 1)[2]. As for insects 11,853 species have been known so far from the territory [1]. According to a recent estimation obtained from comparing this with U.K., which is similar in area, these listings represent, at best, only a quarter of the species actually inhabiting the peninsula, yet to be described [3]. With increasing extent of pollution and deforestation both in the land and sea coast a number of wildlife are endangered or on the verge of extinction. Forest area had been decreasing 8,000 hectares per year during 1967 to 1990, primarily due to road and industrial plant construction, leisure facilities developments like golf courses, ski resorts, condominiums etc. Table 1.

Fungi 1,064 1,625 736 Microorganisms 1,167 28,462 A recent survey has revealed that about 18 % of land vertebrates are endangered or extinct, the same with 19% of freshwater fishes, 60% of amphibians, 45% of reptiles, 13% of birds [4]. 25% of with mammals are known to be gone or endangered. Since the independence of the nation in 1945 after the Japanese rule for 36 years nature surveys were mainly undertaken under the civilian initiative. The Korean Association for Conservation of Nature, founded in 1963, started field surveys from 1970 up to the present time producing more than forty reports covering about fifty different locations in South Korea. The Korean Central Council for Nature Conservation, in addition, set up in 1977, initiated another biological survey program in 1982 and has issued a dozen reports on more than twelve places, mainly island areas. From the governmental side, the Ministry of Environment launched in 1986 the National Ecosystem Survey Project lasting five years to provide basic data to be used in nature conservation policy development. The second 5-year project started in 1997 under the provision of the Law of Natural Environment Conservation that the nature survey should be implemented every ten years. The Office of Forestry also has been conducting the Wildlife Status Survey every ten years, publishing annual reports mainly dealing with mammals and birds. The Ministry of Culture and Sports is carrying out surveys searching species candidate for Natural Monuments. The current policy of biodiversity conservation of Korea originates from the "Basic Plan of Natural Environmental Conservation" [5] and the national plan of "Biotech 2000"[6] announced in 1994 by the Ministry of Environment and the Ministry of Science Technology respectively. Both of them are incorporating biodiversity conservation elements into the plans although not in detail and concrete terms. Several governmental or federally supported NGOs are conducting the relevant programs. 2. National Biodiversity Strategy Planning The Republic of Korea joined the Convention on Biological Diversity on October 3rd, 1994, having been ratified by the General Assembly. For developing the national strategy of biodiversity conservation scientific community including experts from social sciences launched the project Biodiversity Korea 2000 in March 1994. A national forum was held, prior to getting to work, on March 24, 1994 in Seoul. Three months later, on June 15-16, the national conference "Biodiversity Conservation and Development beyond Year 2000 was held to discuss the result of the basic studies done by the 13 task-force groups of the project. Recommendations were adopted and submitted to the related government agencies[1]. Thereafter, the national action planning has been carried out by the Ministry of Environment and National Biodiversity Committee was organized in June 1997, which plans to complete the national strategy by the end of the year. Even though accurate assessment of Korean biodiversity remains far from complete the preliminary study revealed how serious the situation is in this country as mentioned early in the present article. Rapid degradation of biodiversity, decreasing forest area as well as park area per capita every year with increasing population and urbanization require a drastic change in national development policy by incorporating biodiversity conservation principle into the national development motivating not only scientific principles but also socio-economic as well as political measures to be taken all in combination. For this purpose the problems identified in the national forums and discussions carried out so far in different social and scientific sectors should be reviewed and properly adopted. Rather a solid coordination system in terms of administration between different government agencies handling affairs in climate change, environmental pollution, national land development, population control and education at all levels as well as NGO programs should be established so that the problems of biological diversity could be properly incorporated into them and fairly respected in priority. Public education should be emphasized to improve environmental awareness of the lay public as well as high government officials, in particular, at decision-making levels. This type of approach cannot be stressed too much in view of the current pressing problems faced with local autonomy in Korea enacted since 1995. Each province is vying for increasing its local income, calling for leisure facility development, for instance, at the expense of wild habitats for commercial purpose. The Ministry of Environment's plan of setting up the National Biodiversity Center, on the other hand, remains an idea on paper, put in low priority of governmental investment. Emphasis should be put on manpower training in conservation biology, supporting biosystematic and ecological researches which will fill up the extreme lack of basic information on national biota. This kind of policy supporting evolutionary biology will not be realized without substantial awareness of biological diversity as lifesupporting system of nature. 3. Species Diversity and Status in East Asia East Asia is one of the regions most endowed with natural heritage on the earth. Eight of the 25 most plant-rich countries, that is, one third are from the East Asia [7]. China is the third and Indonesia is the sixth in plant diversity of the world. In higher vertebrate animals too East Asia embodies 8 of the 25 most endemic-rich countries as in Indonesia (3rd), the Philippines (5th), China (8th) and so on. It is to be, furthermore, noted that Indonesia is the top in mammal richness over the world. In temperate countries in North East Asia too their species diversities highly outnumber those in Europe and North America for their geohistorical reason. Korea and Japan, for instance, recorded more than 3,200 and 5,500 higher plant species as compared to only 1,400 and 2,600 in UK and Germany respectively which have similar land areas with the former two Asian countries each [3,8]. In spite of the tremendous richness in this part of the world these countries are now facing the greatest extinction rate of biological diversity (Table 2). 1) Vietnam The number of plant species in Vietnam is estimated to be 12,000 of which only 7000 were identified and a recent investigation enumerated 275 species of mammals, 800 species of birds, 180 species of reptiles, 80 species of amphibians, 2470 species of fish, 5500 species of insects, etc. [9]. The rapid population growth and ensuing overexploitation of forest and other natural resources led to the fast degradation of ecosystems resulting in that 28% of mammals, 105 of birds, 21% of reptiles and amphibians are currently listed as endangered species.

The country has been found to be home to (endemic?) 25 species of mammals and birds that are endangered. Laos has not yet joined the Convention on Biological Diversity but is preparing to become the party of the convention in the near future. 3) Thailand Approximately 1,570 species of Thailand's plants have been recorded in botanical references which account for estimated 15% of total vascular plant species in Thailand[11]. It is estimated, however, that there are approximately 15,000 plant species in Thailand which include 3,000 species of mushroom and fungus species, 633 pterophyte and more than 1,000 species of orchid. Concerning animals there are 285 species of mammals in Thailand and six of them are endemic to the country. The number of bird species on record is 915 of which two are endemic. Reptiles on record amount to 313 and amphibians number 106 species whereas 545 freshwater fishes are expected to be in Thailand and 70 species are considered endemic to the country. As for insects 7,000 species have been known which account for only 10% of insect collections at the Department of Agriculture, 90%, therefore, remaining to be identified. Currently, the endangered species in Thailand are 2 amphibians, 12 reptiles, 39 birds and 31 mammal species. An estimation tells there are currently about 107 endemic plant species, 400 endangered species and 600 rare species [11]. 4) China The number of plant and animal species on record in China reaches 88,644 including approximately 30,000 vascular plant species and 499 mammal species whereas insect amounts to 40,000 species which, however, is one fourth of the total estimation[12]. A rough estimation reveals that in China about 398 vertebrate species are endangered amounting to 7.7% of the total vertebrate. In plants, the rare and endangered species are 1,019 in number which is about 3.5% of the higher plants. However, the estimated proportion of endangered or vulnerable plant species is supposed to be about 15-20%, that is, 4,000-5,000 species of higher plants. 5) Japan In Japan 49,230 living organisms including around 35,000 animal species and 14,200 plant species and varieties [3,13]. The animals include 188 mammals, 665 birds, 87 reptiles, 59 amphibians and 200 freshwater fishes in species number. Insects are enumerated to be 28,720 while in a recent survey it turned out to be 30,399 species [14]. The Red Data Book of Japan, however, lists 110 endangered, 114 vulnerable and 415 rare species in animals in addition to 22 extinct ones from the country [15]. The share of endangered, vulnerable and rare species in the total number of species in each category exceeds 15% for all except Insects in which the number of species is overwhelmingly large which, therefore, figures only 206 species or 0.7%. On plant side, its number on record in Japan includes 8,118 species of vascular plants, 1,850 algae, 535 moss, 2,295 lichens and about 1,000 fungi species [15]. Among them are 147 species found to be on the verge of immediate extinction, 677 endangered and 36 in endangered state. They account for 16.8% of about 5,300 wild plant species in Japan. From the overview of species situation with six countries including Korea we could easily state that the inventories are far from complete. They are often restricted to less than one fourth (China, Korea, insects), to one third (Japan, insects), to 15% (Thailand, vascular plants), to three fifths (Vietnam, plants) and even to almost one tenth (Thailand, insects) of the total estimation of the species number in the respective country. To make the matter worse many of them are facing extinction due mainly to deforestation and environmental pollution. Fast population increase in the region certainly will aggravate the situation making more exploitation of nature necessary for routine consumption and local income increase as well. In this context the risks of losing far more number of living species ranges from 7.7% of vertebrate endangered and 3.5% of higher plants in rare and endangered state (China) to 15% of animals and 16.8% of wild plants in endangered or vulnerable state (Japan). It also comes up to 28% of mammals and 21% of reptiles and amphibians endangered in Vietnam. Still the worst is the case with Korea where the endangered amphibian species rate soars up to 60% with average endangered or threatened species rate of vertebrates except marine fishes reaching 18%. In view of this deplorable situation as described above in the extent of poor inventory and endangered species rate of fauna and flora in the region it should become an absolute imperative to take measures for making up the gap of knowledge as well as to lessen the extinction rate of wildlife. Poor expertise in most countries, furthermore, requires cooperation not only for immediate inventory of the biota but also for capacity building for biodiversity assessment of the countries concerned. Now an overview is to be made concerning what kind of efforts are being made for saving the imperiled state of wild-lives in both world and regional as well as institutional dimensions. 3. Current International Co-operations The Convention on Biological Diversity(CBD) was signed and for promoting international cooperation the Article 12 urges cooperation in the use of scientific advances in biological diversity research in developing methods for conservation and sustainable use of biological resources. The contracting parties are also requested to facilitate the exchange of information, relevant to the conservation and sustainable use of biological diversity (Article 17). In the same framework of need to interact among countries the Convention stipulates that the contracting parties should promote international technical and scientific cooperation to realize and achieve the goal of the CBD concerning technical and scientific co-operation(Article 18). The imperative of cooperation is addressed, furthermore, in the Article 15.7 of the Agenda 21 by stating that governments should promote technical and scientific cooperation in the field of conservation of biological diversity and the sustainable use of biological and genetic resources. It notes that special attention should be given to the development of and strengthening of national capabilities, by means of human resource development and institution-building. Under this global demand of cooperation with the issue of biological diversity we will make a simple overview of what are in operation currently as international efforts to implement the cause of CBD and Agenda 21. 4.1. DIVERSITAS of the International Union of Biological Science (IUBS). In the global dimension it was the International Union of Biological Science (IUBS) which initiated the effort of exchange and cooperation among countries by adopting the program "Ecosystem Function of Biodiversity" in 1991. It was developed in 1992 to the new name "DIVERSITAS", co-sponsored with the Scientific Committee on Problems of the Environment (SCOPE) and UNESCO [16]. Still it was expanded later in 1996 as a collaborative program joined by International Council of Scientific Unions(ICSU), International Geosphere-Biosphere Program /Global Change and Terrestrial Ecosystems (IGBP-GCTE) and International Union of Microbiological Societies(IUMS) as additional sponsors [16] DIVERSITAS is concerned with all living organisms on Earth, from the genetic to the ecosystem level. It aims to identify the key scientific questions and to promote collaborative research to address them through international cooperation. With the adoption of the Convention on Biological Diversity in UNCED in June 1992 DIVERSITAS acquired more universally accepted consensus as a global cooperative program. The conceptual framework of the DIVERSITAS program has been designed to address the main scientific issues necessary for a better understanding of the extent, structure, function of ecosystem, and effects of environmental and climate change on biodiversity. Five Core programs Elements represent the major DIVERSITAS research effort: The effect of biodiversity on ecosystem functioning Origins, maintenance and change of biodiversity Systematics: inventorying and classification. Monitoring of biodiversity Conservation, restoration and sustainable use of biodiversity DIVERSITAS runs furthermore five Special Target Areas of Research (STARs) Soil and sediment biodiversity Marine biodiversity Microbial biodiversity Freshwater biodiversity Human dimensions It is to be noted that DIVERSITAS is coordinating a broad research effort in the biodiversity sciences within the international arena as examplified in the "regional initiatives". 4-2. BioNET International BioNET-International was initiated by the intergovernmental CAB-International in 1993 to help generate biosystematic self-reliance in the developing world [17]. It aims to mobilize and pool existing biosystematic resources within developing countries and to increase and sustain these through the transfer of skills, knowledge, scientific expertise and other resources from developed country institutions. It is also envisaged as a series of interlinked subregional Technical Co-operation Networks in developing countries (known as Locally Organized and Operated Partnerships or LOOPS), supported by a consortium of expert institutions from developed countries. Four priority areas have been identified for the initial focus of the LOOPS: information and communication services training of personnel rehabilitation of collections and the establishment of new resources, and the development and application of new resources. In June 1994, the first LOOP was established in Europe (EuroLOOP), including 60 institutions representing 22 countries. The first sub-regional LOOP, an association of seven Caribbean states known as CARINET, was formed in December 1993. It is expected that four other LOOPS in East Africa (EAFRINET), Southeast Asia (ASEANET) will be developed in the near future [17]. 4.3. Systematics Agenda 2000 Initiated in 1994 by the Consortium of the American Society of Plant Taxonomists, the Society of Systematic Biologists, and the Willi Hennig Society, Systematics Agenda 2000 was launched as a global program having as a major objective the building of systematics infrastructure and human resources throughout the world [18]. The principal objective is to initiate three programs (1) inventorying the world's species, (2) developing a phylogenetic understanding of life's diversity and (3) organizing all forms of systematics information into an efficiently retrievable form that best meets the needs of science and society. These programs are expected to provide knowledge to conserve and sustainably use the components of biodiversity. Systematics Agenda was recognized and adopted by international community including IUBS as The Systematics Agenda 2000 International Program (SA2000/I). It held its first Steering Committee meeting in 1415 October 1997, in Crete, Greece. 4.4. SPECIES 2000 The Species 2000 objective is to enumerate all known species of plants, animals, fungi and microbes on Earth as the baseline datasets for studies of global biodiversity. The idea was first initiated by a biology team of the Southhampton University, U.K. and proposed to IUBS General Assembly in September 1994 and later funded by UNEP and GEF. The names as well as localities, synonyms, specimens and references provide the crucial link both in communication of biodiversity information, and in accessing the data of pure and applied biological disciplines. The overall goal is to create a global species database (GSD) and to involve collaboration and link with existing other databases to expand its utility. The output will be an important information source needed by countries for the implementation of the Convention on Biological Diversity, providing support for the preparation of surveys and inventories of biodiversity, and a common medium for global communication about biotic resources, their utility and conservation. The first workshop was held on March 10-13, 1996 in Manila and was transformed to the "Species 2000 Federation" recruiting 20 GSDs over the world. 5. Regional Initiatives 5.1. DIVERSITAS's Network in the West Pacific and Asia (DIWPA) As a regional network for DIVERSITAS in Western Pacific and Asia area DIWPA was founded in 1995 under the initiative of the Center for Ecological Research of the Kyoto University, Japan, to promote studies and utilization of biological diversity in this region. IWPA held its first meeting in Singapore in December 1995 to exchange information and discuss unifying methodology on the study of biodiversity, and to plan international network of field stations in the region[19]. Membership comprises 250 scientists from thirty five countries. It holds the DIWPA Second Symposium/Workshop on Monitoring and Inventorying of Biodiversity in Western Pacific and Asia during November 14-16, 1997 in Taipei. 5.2. East Asian Network for Taxonomy and Biodiversity Conservation (EANetTBC) In the series of gatherings on biodiversity held during the last few years in the East Asia it came out clear that the extreme lack of resource base of taxonomy in the region made it extremely difficult for each country to properly implement what the Convention on Biological Diversity (CBD) requires. Since the shortage of taxonomical experts has become a global issue, especially in developing countries, the Subsidiary Body on Scientific, Technical and Technological Advice (SBSTTA) meeting in September, 1996 in Montreal, made very strong recommendations for "Capacity Building for Taxonomy" and it was endorsed afterwards in November by the meeting of the Conference of the Parties (COP) in Buenos Aires, particularly with regard to implementing the article 7 of CBD (assessment and monitoring). It was in this context that "International Conference for Taxonomy and Biodiversity Conservation in East Asia" was held in Seoul during June 12-14, 1997 inviting delegates from twelve countries of the region, initiated by the Korean Biodiversity Council and Korean Institute for Biodiversity Research of Chonbuk National University of Korea[20] . As a result East Asian Network for Taxonomy and Biodiversity Conservation was formed as co-operational body to enhance the capacity building for systematics in the region. It published its initial issue of the newsletter "TaxoNewSia" in October 1997. This regional effort was formally endorsed at Crete meeting in October by DIVERSITAS-Systematics Agenda/International mentioned above. 6. International Cooperation: An Imperative. Such profound lack or shortage of even basic inventory data in the East Asia countries prevents studies of populations of species and the monitoring of biodiversity at the species level or below, not to mention conservation strategy development and ecosystem function analysis. The inventorying and monitoring should come first in any biodiversity conservation efforts. The task, however, seems so huge and unending, and the economic benefits so vague or apparently non-existent, few governments provide adequate resources. It is clear, therefore, that the inventorying and monitoring of biological diversity requires substantial systematic and ecological infrastructure, economic input and human resources[17]. Such requirements exceed the capabilities of even the most scientifically advanced nations. Thus, there is a need to share and co-ordinate expertise and capacity. The international co-ordination of effort is also essential because the processes and patterns of biodiversity are not restricted by political, social or economic boundaries. Integration is essential if resources are not to be wasted. The third reason for international cooperation, specifically speaking, is the small number of taxonomists and reference collections as well. Lack of adequate local, regional and international resources for systematics is one of the greatest problems for inventorying 17]. According to a survey estimating geographical fractions of the world ecologists and insects taxonomists 78.3% and 78.5% of the respective groups are distributed in Palearctic and Nearctic regions [21] which reveals a striking population bias of the expertise to the northern and northern-temperate countries. This was found to be the same also with reference collection. So far 2.5 billion natural history collections have been known over the world but most are in Europe and North America [22]. Europe is considered to preserve over half the world's reference collections and probably as much as 90% of the world's type specimens [23]. Specifically, it is estimated that they contain nearly 80% of all the world's cryptogamic plant types for instance. This kind of tilting trend of systematics resources makes it an overall necessity to cooperate with key European and North American institutes but it should justify the absolute need of international cooperation among the states of East Asia for their building taxonomic capacity of self-reliance as soon as possible. Two recent initiatives, in this sense, Systematics Agenda 2000 and BioNETInternational among others may be worth mentioning, which seek to solve the problems. In the regional dimension ASEAN Network of BioNET was set up under the name ASEANET [17]. As another regional network DIWPA was launched as part of DIVERSITAS covering west Pacific and east Asian region, followed by EANetTBC for taxonomy in East Asia mentioned earlier. The discussion of various topics on biodiversity in the region, in addition will help to open the new horizon for the improvement of the situation through regional cooperation, which is rigorously stressed throughout CBD and Agenda 21. This kind of effort should be an imperative, therefore, not only for the immediate need in the present day for biodiversity conservation but also for science and welfare of the future generations of East Asian countries.
