Studies on the preservation and propagation of tropical and subtropical plants are required, but the studies are insufficient in Korea. Since 2013, the Tropical Plant Resources Research Center has been collaborating on field research and publication to preserve plant diversity in Myanmar protected areas and Sagging areas in cooperation with Ministry of Natural Resources and Environment Conservation and the Myanmar Forest Research Institute. This study is to provide information on cooperative projects. As a result of the joint research between the Korea National Arboretum and Myanmar, in December 2018, the Korea National Arboretum Tropical Plant Resources Research Center is on display for conservation and education purposes with the 65 Myanmar useful materials and specimens of 326 kinds of plants and specimens that Myanmar Forest Research Institute donated. This donation is the first case of Myanmar's export of plant organisms to a foreign country, and as for the Korea National Arboretum, it is the second official case of introducing a mass plant from foreign governments. The study will also accelerate preservation biodiversity and propagation methods of tropical and subtropical plants as well as research on biodiversity conservation and industrial use.

Floristic study can help to understand the current status of species diversity, evaluate and predict distribution changes of plants based on the specimens, and record the climate environment and biodiversity of the Korean Peninsula. Boraebong is an area that has plant resources of conservation value, but there is concern about artificial interference through trail and forest road. Therefore, this study aims to report the vascular plants of Boraebong based on voucher specimens and photos and to use them as baseline data to conserve biodiversity of Boraebong. Also, it will be useful to prevent additional influx of invasive species through comparison with previous studies. The investigation was carried out 11 times from April to September in 2022 and confirmed a total of 455 taxa including 87 families, 269 genera, 401 species, 13 subspecies, 35 varieties, 6 forms. In addition, we confirmed the 4 taxa of red list plants (EN 2 taxa, NT 2 taxa), 18 taxa of Korean endemic plants, and 102 taxa of floristic target species (V degree 1 taxon, IV degree 16 taxa, III degree 31 taxa, II degree 31 taxa, I degree 23 taxa). Furthermore, alien plants 17 taxa, invasive species 2 taxa, useful plants 439 taxa were confirmed in Boraebong. As the results of comparison with previous studies, 98 total taxa including 38 families, 76 genera, 86 species, 1 subspecies, 8 varieties, 3 forms were newly identified in this study.

This study was conducted to evaluate influence of chemical properties in the riparian on the species diversity and to get plant information for enhancement of natural purification in Mankyeong River. The concentration of total nitrogen was high in Jeonju and Sam stream, while that of total nitrogen showed the highest peak in Winter. Concentrations of $NH_4-N$ was $0.01{\sim}0.06\;mg/L$ in Gosan and Soyang stream. The water quality of upstream along with Mankyeong River was suitable for the irrigation source. The riparian vegetation was investigated by Zurich-Montpellier school's method from June, 2001 to September, 2002. The number of riparian plants were 59 families, 129 genera, 165 species, 20 varieties in Gosancheon, on the while 53 families, 111 genera, 141 species, 19 varieties in Soyangcheon. The number of riparian plants in Bari basin was higher than that of other sites namely, 73 families, 134 genera, 218 species, 33 varieties. Riparian vegetation was consisted of 12 plant communities. The contents of organic matter, total nitrogen and electrical conductivity had negative relationship with species diversity (Species richness index, Heterogeneity index, Species evenness index Species number). On the while, species diversity had positive relationship with soil pH. Species diversify of the plant communities were affected by topography and disturbance.

This study aimed to elucidate the distribution of vascular plants in Mt. Goryeo in Ganghwa-gun, Korea. The results of 14 field surveys from March 2018 to August 2019 identified 629 total taxa, representing 568 species, 10 subspecies, 45 varieties, two forms, and four hybrids in 371 genera and 112 families. The plant formation of Mt. Goryeo is the deciduous broad-leaved and conifer mixed forest, which is the common one in the middle part of the Korean Peninsula. Most parts of the mountain are covered with a young secondary forest, mainly composed of Quercus and Pinus spp. Out of the 629 taxa, 314 were first recorded in the region, six were endemic to Korea, four were listed on the Korean Red List of threatened species, 63 were floristic target plants, and 58 were invasive alien plants. The percentages of the naturalized index (NI) and urbanization index (UI) were 9.2% and 15.5%, respectively. The area showed a high plant diversity with many rare plants and phytogeographically important plants. This study discussed in detail conservation strategies to ensure biodiversity and effective management of Mt. Goryeo. The study results can be used as the reference for the preparation of biodiversity conservation and the establishment of management measures.

The criteria which have been used for the assessment of wildlife conservation values and particularly botanical values during the last decade, 1969~1986, were reviewed in order to select an appropriate set of criteria applicable for Korea. Fifteen studies, including studies of particular sites reviews of ecological evaluation are reviewed. Four criteria, rarity, diversity, size & extent and naturalness were used in more than half of these studies reviewed. The sixteen components were arranged with the scale of the sites, in view of the Korean situation. The human Interference, ecological fragility. as well as rarity, etc. were major components to be considered at small scale sites. In the contrary, area, diversity position in ecological and geographical unit, and naturalness, etc. considered the major components at larger scale sites. The components such as uniqueness, typicalness, research and educational, etc. were considered both applicable. Although this criteria should be tested by applications in the field and amended there after, It will be one of the first-step to evaluate of the protected areas, as well as specific plant species in the future.

Agaricus bisporus is an important edible mushroom that is used as a functional food. In this study, European A. bisporus strains were analyzed for genetic diversity, population structure, and genetic differentiation using simple sequence repeat (SSR) markers. European A. bisporus strains were divided into four groups by distance-based analysis and two subpopulations by model-based analysis. The SSR markers used in this study did not group European A. bisporus strains by geographical region or pileus color. Genetic diversity was high in Group 4 based on distance-based analysis and Pop. 2 based on model-based analysis. A. bisporus strains showed very low genetic differentiation. The results of this study can be used for breeding A. bisporus in the future.

희귀식물은 야생화 애호가의 선망의 대상이다. 희귀식물을 찾기 위한 애로호가들의 활동은 참으로 열성적이다. 그런데 희귀동식물은 단순히 희귀성을 쫓는 사람들에게만 중요한 존재가 아니다. 희귀식물은 미래의 자원으로서 활용가치가 뛰어나기 때문에 국가 차원의 보호노력이 요구된다. 특히 우리만이 가지고 있는 자원이라면 그 상대적 활용가치는 무궁무진하다. 세계 여러 나라가 생물다양성협약에 주목하는 이유이기도 하다.
