Present problems of the Korean rare and endangered plant species evaluations are discussed. It is proposed that the evaluation criteria for Korean rare and endangered are urgently needed in the future. The translation of new proposed criteria into Korean should be discussed in order to avoid confusion in the future. The draft of a new criteria system for rare and endangered plant species. prepared by the S. S. C. (Species Survival Commission) of I. U. C. N (International Union of Conservation of Nature) are introduced. The proposed draft for the criteria being developed by the S. S. C. of I. U. C. N. are Extinct, Extinct in the Wild, Critical, Endangered, Vulnerable, Susceptible, Safe /Low Risk, Insufficiently Known, and Not Evaluated. It is expected to take the more time to be technically developed further and also officially recognized by the I. U. C. N. for the practical use in the future.

Based on the specific plant species for environmental assesment by the Ministry of Environment(MoE), a total of 68 taxa were identified; 29 taxa for the floristic degree(FD) I, 12 taxa for the FD II, 11 taxa for the FD III, 9 taxa for the FD IV and 6 taxa for the FD V. The endangered plant species, in Woraksan National Park, such as Lilium cernum and Berchemia berchemiaefolia are categorized as the Conservation Degree (CD) II which is designated by the MoE. The rare and endangered species such as Crypsinus hastatus, Lilium cernum, Berchemia berchemiaefolia, Lilium callossum, Gastrodia elata, Aristolochia contorta, Koelreuteria paniculata, Rhododendron tschonoskii, Scopolia japonica, Cypripedium macranthum, Paeonia japonica and Thymus quinquecostatus including 12 plant taxa are categorized as Rare and Endangered Plant Species by the Korea Forest Service.

This study is to establish the Incheon Metropolitan City Arboretum Development Plan (IMADP) as a capacity building both for plant diversity conservation and nature friendly leisure activity areas of Incheon Metropolitan City, Korea. The arboretum planning area is located within territory of the Incheon Grand Park Based on the IMADP, the arboretum was divided into three display spaces; the Urban Greening Garden, the Rare and Endangered Plant Species Garden and the Theme Garden. Detailed planting guidelines were suggested according to the three garden areas. The Urban Greening Garden was designed to display the following three; the relevance techniques, the model, and the practical uses of plants that are regarded to an urban greening. The Rare and Endangered Plant Species Garden (REPSG) was planned for the collection and display of the rare and endangered native plants in the territories of Incheon and the island seashore. Also, the REPSG includes the education purposes of comparing and displaying taxonomically related plant species. The Theme Garden was projected for the collection and display of plant species that have long been familiar to Korean culture and which are also used in our daily life.

The vascular plant species in the areas of Gonamsan and Shiribong in the Baekdudaegan were summarized as 295 texa: 89 families, 193 genus, 245 species, 44 varieties and 6 forms.10 taxa were recorded in the surveyed areas as the Korean endemic plants: Hosta capitat (Liliacease), Polygonatum lasianthum var. corenum (Liliaceae), Chloranthus japonicus (Cloranthaceae), Salix hulteni (Salicaoeae), Clematis richotoma (Ranunculaceae), Spiraea prunifolia for. simpliciflora (Rosaceae), Vicia unijuga (Fabaceae), Viola albida (Violaceae), cornus walter(Cornaceae), Weigela subsessilis (Caprifoliaceae).According to the list of Korean rare and endangered plants complied in the studied areas:Iris ensata var. spoyanea(Iridaceae), Viola albida (Vioaceae) and Aristolochia contorta (aristolochiaceae) Due to the rapid destruction and increase of visitors and the studied areas are located close to the villages, the naturalized plant species in the areas were more frequently appeared than the rare and endangered plant species.

Tissue culture techniques arguably are an important approach for ex situ conservation of rare and endangered plant species. However, there is utmost importance on maintaining the genetic integrity of the introduced plants especially in tree species. To examine the genetic integrity of the micropropagated plants, we randomly screened few hardened plants of Syzygium travancoricum, a critically endangered tree taxon, using Randomly Amplified Polymorphic DNA (RAPD) markers. Twenty-three random. primers were tried and twenty-five polymorphic loci were identified. The dendrogram based on the Unweighted Pair-Group Method Arithmetic Average and Nei's similarity index depicted about 97% homology between the mother plants and micropropagated plants. Further, an attempt was made to reintroduce the micropropagated plants in the wild. Over three hundred small trees could be successfully established.

Lychnis wilfordii (Regel) Maxim is a rare and valued ornamental plant. Germination rate reached 46.6% when seeds were treated with $100mg{\cdot}l^{-1}$ GA (Gibberellic acid). The highest callus induction was observed in the leaf explants of the seedlings on MS medium containing specific concentrations of $0.5mg{\cdot}l^{-1}$ BA ($N^6$-benzyladenine) and $3.0mg{\cdot}l^{-1}$ NAA (a-naphthalene acetic acid). The adventitious shoot was formed in 97.3% of calli on 1/2 WPM (Woody Plant Medium) medium. Shoot elongation of in vitro propagated plantlets was no difference among various medium. The plantlets grew well after transferring to the pot. This in vitro propagation protocol should be useful for conservation of this endangered plant.

Understanding the factors relevant to endangerment and the patterns of habitat locations in relation to protected areas is critically important for the conservation of rare species. Although 64 plant species have recently been listed as endangered species in Korea, this information has, until now, not been available, making appropriate management and conservation strategies impossible to devise. Thus, we collected information on potentially threatening factors, as well as information on the locations in which these species were observed. The potentially threatening factors were classified into seven categories. National parks, provincial parks, ecosystem conservation areas, and wetland conservation areas were defined as protected conservation areas. Korean digital elevation model data, along with the maps of all protected areas were combined with the maps of endangered plant species, and analyzed via Geographic Information Systems (GIS). Excluding the category of "small population", endangered plant species in Korea were associated more frequently with extrinsic factors than intrinsic factors. Considering land surface only, all conservation areas in Korea totaled 4.9% of the land, far lower than International Union for Conservation of Nature and Natural Resources (IUCN)'s 10% coverage target. At the species level, 69% of the endangered plant species were detected in conservation areas, mostly in national parks. However, this result demonstrates that 31% of endangered species inhabit areas outside the conservation zones. Furthermore, at the habitat level, a large proportion of endangered species were found to reside in unprotected areas, revealing "gaps" in protected land. In the face of rapid environmental changes such as population increases, urbanization, and climate changes, converting these gap areas to endangered species' habitats, or at least including them in habitat networks, will help to perpetuate the existence of endangered species.

The twenty eight taxa of rare and endangered plant species of Oesorak were investigated in the field, and the results were compiled according to the literature by Lee et al.(1996). Most of the populations of the investigated plants are located in the vicinity from the mountain trails which is the destruction pressures high. Also these plants are envisaged from the possible collections for both edible and medicinal purposes by local peoples, so the conservation strategies at the levels of habitat and species must be prepared. Taxuscaespitosa of Taxaceae has very few individuals and the status of the habitats envisaged serious problems from tramplings.

현재 중국에서는 100개 이상의 식물원이 있으며, 대부분의 식물원은 희귀식물이나 멸종위기 식물의 생식질 자원을 보유하고 있다. 중국의 식물원에서 현지 외 보전과 이와 관련한 일을 수행하기 위하여 1999년 REPC-CBG-DATA라는 데이터베이스를 구축하였다. 본 데이터베이스 구축 결과에 따라 중국내 389종의 희귀 및 멸종위기 식물에 대한 다양한 정보와 보전상태를 분류하였으며, 이를 토태로 관리보전에 활용할 수 있게 되었다. 본 논문에서는 중국 내 희귀 및 멸종위기 식물의 보전을 위하여 각 식물원에 수집된 식물종을 대상으로 REPC-CBG-DATA를 바탕으로 각 해당 식물종의 관리에 대하여 토론하였다.
