한국 특산 식물인 미선나무 (Abeliophyllum distichum)는 IUCN Red List의 EN (위기종) 등급에 지정되 어 보호받아 왔다. 미선나무는 국내 자생지 6곳을 포함하는 13개의 서식지에서 생육되고 있다고 알려져 있다. 2017년 이후, 국내에서는 지속적인 보전과 관리하에 법정보호종에서 해제되어 멸종위기종 복원 성 공 사례의 귀감이 되었으나 국내를 제외하면 미선나무의 활용은 아직 어려운 현실이다. 미선나무는 1속 1종이지만 종 내에서 다양성이 존재한다. 꽃의 형태적 특징에 따른 다양한 분류가 이루어지며, 옥황1호을 포함한 분홍, 상아, 연녹색, 흰색 등으로 구분된다. 유전체 연구 및 성분 분석을 통해, 각 표현형마다 유전 정보와 유효 성분의 차이가 존재한다는 것이 알려졌다. 활용 가치를 높이려면, 유전적으로 안정되고 표준화가 가능한 원료가 필요하며, 이는 신품종을 이용하거나 새로운 개발이 필요하다는 것을 내포한다. 일반 식품으로의 활용은 어려우나 기능성 화장품의 원료 등으로 활용되고 있으며, 이러한 활용들은 미선나무의 높은 활용 가치를 투영한다. 활용 가치 평가를 위해 수행된 DNA 손상, 멜라닌 생합성, 항염증, 항산화, 항암 억제 등의 연구를 통해 다양한 약리학적 효능을 가진다는 결과들이 도출되었고, 많은 문헌들이 그 근거를 뒷받침한다. 또한, 유효 성분의 합성경로를 재정립하고 RNA 분석을 통해 그 양상을 예측하기 위한 연구가 진행 중에 있다. 미선나무에서 유래한 식물조직 배양체인 callus의 유도 및 배양이 진행되고 있으며, 옥황1호 유래 callus를 활용하여 다양한 연구를 수행하고 있다. 앞서 언급한 미선나무 연구 및 개발에 대한 한계를 파악하고, 천연 식물 자원으로의 미선나무에 대한 지속적인 관심과 지원을 통해 나고야의정서에 대응하는 전략적 접근이 필요하다.

Euryale ferox is only annual hydrophyte among endangered plants in Korea and its seed is high valuable medicinal material. This studies were carried to find out key factors that made E. ferox endanger in Korea and to apply the results for effective management of the natural wetlands inhabited by E. ferox. We investigated the distributed sites reported by previous studies and classified the distribution-affected factors into three categories, eutrophication(hypothesis 1), soil accumulation(hypothesis 2) and increasing of water level(hypothesis 3) in the habitat. These three hypotheses were tested in the field and explained the results with the morphological characteristics of seed germination stages of E. ferox. The geographical distribution ranges of E. ferox diminished at a rate of $1^{\circ}$ latitude with about 10 natural wetlands for last 30 years. Water eutrophication in the wetland had a positive effect on the establishment of E. ferox. But higher in soil accumulation and water depth, then lower in the establishment rate of E. ferox. These results indicate that water depth in the wetland must be below 50cm during the germination season, especially in May and emergent hydrophytes filter zone is need to protect soil accumulation from soil erosion within its watershed for the effective management of wetland with E. ferox.

The research status of endangered amphibians in Korea was mainly studied the life-cycle and distribution status of species from the 1980s to the early 2000s. Although a relatively diverse range of studies have been conducted on mackerels, studies on habitat prediction, analysis, change and management are insufficient. WEB, which provides biota information using location information in Korea, is a site operated by the National Bio Resource Center under the Ministry of Environment, but there is no information on endangered species and general species information has also been found to be very scantily. For this research, we secured a database of location information of Narrow-mouth frog, an endangered species, by combining literature and field research, and established a system by applying new technologies and open-based platform technologies that can be easily accessed by non-technical personnel of IT among IT technologies. The system was divided into administrator functions and user functions to prevent indiscriminate sharing of information through authentication procedures through user membership of users. The established system was authorized to show the distance between the current location and the location of the Narrow-mouth frog. Considering the ecological characteristics of the Narrow-mouth frog, which is an endangered species, a radius of 500m was marked to determine the habitat range. The system is expected to be applied to the legal system to change existing protected areas, etc. and to select new ones. It is estimated that practical reduction measures can be derived by utilizing the development plan for reviewing the natural environment. In addition, the deployed system has the advantage of being able to apply to a wide variety of endangered species by modifying the information entered.

The most important thing for conserving plant diversity in an area is to make an overall inventory of the plant species inhabiting the area. In particular, limestone areas are known for their high plant diversity and distribution of specific plants. Despite that, only a few have been designated as protected areas. This study investigated the vascular plants distributed in Goyangsan Mtn. and Munraesan Mtn., located in limestone areas of the central part of the Korean Peninsula. A field survey was conducted eight times from April to October 2021. As a result, we identified a total of 654 taxa comprising 113 families, 357 genera, 592 species, 15 subspecies, 44 varieties, and 3 formulas. They included four endangered wild plant species: Astilboides tabularis, Eleutherococcus senticosus, Cypripedium macranthos, and Epilobium hirsutum. Endemic plants in Korea were identified as 32 taxa. Floristic target plants were identified as 168 taxa, specifically 5 taxa of grade V, 41 taxa of grade IV, and 36 taxa of grade III. The red data plants included 2 taxa as "Endangered (EN)", 7 taxa as "Vulnerable (VU)", and 7 taxa as "Near threatened (NT)". A total of 41 taxa of naturalized plants were identified, and 4 of them were invasive alien plants. The surveyed vicinity of Goyangsan Mtn. and Munraesan Mtn. showed high plant diversity and contained core habitats for distribution of an endangered wild plant, Astilboides tabularis,in the limestone area. Moreover, both mountains contained a small population of Cotoneaster integerrimus. These findings confirm that the area has conservation values. Therefore, we propose to identify areas with high plant diversity and designate them as special protected areas.
