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.

Amid the recent intensification of climate change, the decline of subalpine coniferous species is evident. Accordingly, the Korea Forest Service is conducting research to establish conservation measures, identify the causes of the decline of subalpine coniferous species, and establish conservation strategies for seven species of conifers in the alpine region. This study used an economic value evaluation method to present objective data to inform the need for and value of conservation of endangered coniferous species through the recognition of endangered coniferous species and evaluation of conservation value among coniferous species conservation strategies in endangered alpine areas. A contingent valuation method was applied. As a result, the estimated conservation value per household of endangered alpine coniferous species was 49,181 won.

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.

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.

1997년 4월부터 1998년 4월까지 경상북도 내연산 일대의 관속식물상 조사를 실시한 결과, 관속식물은 100과, 350속, 538속, 1아종, 92변종, 10품종, 1교잡종 총 642종류(texa)를 확인하였으며, 이 중 211종류는 금번조사에서 새롭게 추가하였다. 특히 고란초, 부들, 창포, 꽃창포, 노랑무늬붓꽃, 산작약, 둥근잎꿩의 비름, 꿩의 바람꽃, 연잎꿩의다리, 참좁쌀풀 등의 희귀 및 멸종위기 식물을 확증표본과 함께 보고함으로써 본 지역 식물상 조사에 큰 의의가 있다고 판단된다. 본 조사에서 확인한 희귀 및 멸종위기 식물은 총 29종류로서, 환경부 법정보호식물이 3종류, 환경부에서 실시하고 있는 전국자연환경조사에서 제시한 특정식물종 중 정밀생태종은 27종류, 그리고 산림청 희귀 및 멸종위기 식물은 15종류로 나타났으며, 둥근잎꿔의 비름, 망개나무, 노랑무늬붓꽃 등의 분포 등에 대해 논하였다.

Sedirea japonica is one of the critically endangered species in South Korea mostly due to artificial harms such as illegal collection and habitat destruction. Therefore, artificial propagation through improving germination rate, increasing growth, and controlling flowering is meaningful for the conservation and reintroduction of S. japonica. It is suggested that cytokinins are one of the multi-factors that contribute to plant growth and floral responses. Especially, exogenous cytokinins have been known to induce or promote shoot growth or earlier flowering in orchids. Therefore, it was investigated how the application of 6-benzylaminopurine (BA) influenced the growth and inflorescence of S. japonica. A foliar spray containing BA at 100, 200, 300, and 400 ppm was applied from 1st July to 30th December 2021. Leaf length, leaf length growth rate, leaf width, and width and length ratio were measured as growth-related factors. Visible inflorescence rate, inflorescence length, the number of flowers per inflorescence, and the distance between the stalks were measured as flowering-related factors. Growth-related factors except for leaf growth rate were not affected by BA treatments, while leaf growth rate was significantly increased by 200 ppm of BA treatment. The visible inflorescence rate increased by 200 ppm of BA treatment, and there seems an optimal concentration and threshold of BA treatment. An iterative experiment with more seedlings and measurement factors would be helpful to figure out the effects of exogenous BA treatment on S. japonica, and it can be applied for mass propagation.

This study analyzed potential breeding sites for black-faced spoonbills on 70 non-breeding, uninhabited islands in Incheon, Korea, in order to suggest potential breeding sites for black-faced spoonbills, whose breeding population has recently been increasing. By comparing the environmental characteristics of breeding and non-breeding areas identified through a literature search, we developed a discriminant to identify potential breeding areas for black-faced spoonbills. Among a total of eight environmental variables(Island area, distance from land, distance to mudflat, distance to rice field, distance to sea route, depth of water, mudflat area, rice field area), the variables that influenced the selection of breeding sites for black-faced spoonbills were average water depth, tidal flat area, and paddy field area. As a result of discriminant analysis of breeding islands using these variables, the accuracy was found to be quite high at 80%. As a result of applying the developed discriminant to non-breeding islands located in the Incheon region, a total of 9 islands(Yongrando, Goseokdo, Beolyeom, Joreumseom, Goeriseom, Hambakdo, Moido, Bigajido, Ahyeom) were identified as potential breeding grounds for spoonbills. The research results can be used as basic data for future management of black-faced spoonbill breeding sites and selection of alternative habitats.

Banana is the eighth most important crop in the world designated by the United Nations Food and Agriculture Organization (FAO). In terms of production, it is the fourth most harvested crop following wheat, rice, and corn, considered to be a promising food source for mankind as it is not only scrumptious but also rich in nutrients. However, abnormal cultivation methods that mankind has invented to breed bananas is currently pushing them to the state of extinction. The aim of this study is to develop information-rich digital contents that can easily and intriguingly convey information about steadily but certainly increasing risk of banana extinction. The end-users are middle and high school students who are assumed to be aware of the agricultural revolution through their school curriculum. The linear storytelling method was meant to encourage the end-users to be interested in the causes and processes in which banana has become endangered. For generating a natural interaction between the content and the end-users, a parallel, upper-lower structure was used, in which the relationship between the stories comprising several stages and the information graphic supporting each story is represented. This paper can support an information campaign about the endangered species.
