As part of a study to understand the current status of Korean plant species propagated in foreign countries, we conducted extensive surveys on Korean living collections in the Arnold Arboretum of Harvard University, the oldest public arboretum in North America. Specifically, we collected and identified the voucher specimens of the living collections and further examined the collection databases to understand the history of how Korean plants were introduced to the Arboretum. We found that a total of 154 Korean taxa (belonging to 49 families and 81 genera) have been planted in the arboretum. Most plants originated from seeds that were directly collected in Korea or obtained via seed exchanges with botanical gardens in Asia, Europe, and U.S.A. Of the 154 taxa, 16 are Korean endemic species, and three are listed as endangered species. In addition, 62 taxa are as floristic regional indicator species of Korea used by the Ministry of Environment.

This study was carried out to elucidate the distribution of vascular plants and their usefulness of Mt. Munsusan (1,205 m) in Bonghwa County, North Gyeongsang Province, South Korea. The vascular plants that were investigated in 2 years (2019 ~ 2020) with 15 times consisted a total of 571 taxa; 94 families, 310 genera, 496 species, 4 subspecies, 63 varieties and 8 formas. For the Korean endemic plants, 17 taxa were recorded and 3 taxa of Vulnerable Species (VU) and 9 taxa of Least Concerned species (LC) categorized by the Korean Forest Service as rare plants were investigated in this region. Furthermore, IV, III degrees of floristic regional indicator plants designated by the Korean Ministry of Environment included 8 taxa and 27 taxa, respectively. Among them, edible, medicinal, ornamental, feed/composting, industrial plants were 391 taxa, 359 taxa, 301 taxa, 241 taxa, 217 taxa, respectively. In addition, 25 taxa of naturalized plants were observed.

This study suggested the planting models of Carpinus turczaninowii community to make in Badahyanggi Arboretum and was carried out to the structure of C. turczaninowii commnity in Daebu-Yeongheung Islands. In order to identify the current ecological environment, this study set to 13 plots(i.e. 100㎡) for analysing detailed structure of plant communities. The research methodology was qualitative analysis. It used TWINSPAN, PCA and Indicator Species Analysis tools which are performed well in several comparisons of classification techniques and one of the ordination techniques showed that the plant communities. The results were classified into 3 communities that C. turczaninowii-Pinus densiflora community(I), C. turczaninowii-Quercus serrata community(II) and C. turczaninowii-Platycarya strobilacea community(III). In all of communities, C. turczaninowii was dominant species in canopy layer and understory layer, the degree of closure was high. Proposed the planting models that are I~II communities based on planting status in Badahyanggi Arboretum(Island Plant Botanical Garden), the structure of plant communities, indicator species and individual distribution by DBH classes. Also, The multi-layer planting plans are necessary, such as P. strobilacea, Lindera erythrocarpa, Viburnum carlesii, V. dilatatum, Ligustrum obtusifolium, Zanthoxylum schinifolium and so on.

This study tries to provide the basic direction to form the arboretum with the distinct features by providing the basic data to help the differentiated strategy for each arboretum. For this purpose, the users' pattern, importance of the indicator by the function, and the stimulation and specialization importance were examined for Daegu Arboretum, Gyeongbuk Arboretum and Gyeongnam Arboretum in Gyeongsang Province. The result says, looking into the functions of arboretum, the collection function showed the highest importance in the preservation of the endangered crisis species; the display function showed the highest in the use as the nature experiencing spaces through the plant exhibition; the research function showed the highest in the study on Plant Systematics; the education function showed the highest in the protection of the native plants; and the recreational function showed the highest in the healthy recreational space. In the plan for the promotion of the arboretum showed the highest in the public education program operation such as the narration from arboretum and education for plant. Therefore, it is considered to need the system setup such as the education program, material development and specialist training in terms of the arboretum. For the specialization plan for arboretum in this study, it seem desirable to concentrate on the research and education related to the natural resources renewal, for Daegu Arboretum; to concentrate on the resort site for the protection and display of the species and the disabled visitors by utilizing the geographical traits in the mountains, for Gyeongbuk Arboretum; to create the specialization plan mainly for the tree species suitable for the warm weather and for the children.

This study was carried out to inventory the vascular plant flora in Deokjeokdo and its adjacent regions (Mungapdo, Soyado), Ongjin-gun, South Korea, from April to October 2014. Based on the voucher specimens, vascular plants in this area consisted of 108 families, 362 genera, 578 species, 5 subspecies, 66 varieties and 4 forms, totally 653 taxa. In the flora of this area, 5 taxa of Korean endemic plants were found distributed in the sites, including Hepatica insularis Nakai and Asarum glabrata (C.S.Yook & J.G.Kim) B.U.Oh. Korean rare and endangered plants found in this area were 1 taxa of Critical Endangered Species (CR) and 5 taxa of Vulnerable Species (VU). The floristic regional indicator plants found in this area were 67 taxa comprising 3 taxa of grade V, 2 taxa of grade IV, 12 taxa of grade III, 3 taxa of grade II and 47 taxa of grade I. Naturalized plants consisted of 67 taxa, such as Chenopodium album L. and Erigeron annuus (L.) Pers. were recognized widely distributed in the area.

This study was carried out to investigate the forest community classification and vegetation structure in NYNRF(National Yonghyeon Natural Recreation Forest). We studied by 26 plots($20{\times}20m$) from April to September 2014. NYNRF were classified into the Quercus mongolica Community, Quercus variabilis community and Acer pictum community in the 3 community units. The Q. mongolica Community was subdivided into the Pinus densiflora group and Typical group and A. pictum community was also subdivided into the Euonymus sachalinensis group and Typical group. NYNRF were classified into 3 communities and 4 groups and 5 VU(vegetation units). According to the result of importance value analysis between vegetation units, VU 1 P. densiflora(65.1%), VU 2 Q. mongolica(73.6%), VU 3 Q. variabilis(75.1%), VU 4 E. sachalinensis(33.3%) and VU 5 Lindera erythrocarpa(27.1%) were highly showed in tree layer and VU 1 Rhododendron mucronulatum (19.3%), VU 2 Calamagrostis arundinacea (16.9%), VU 3 Indigofera kirilowii (75.1%), VU 4 and VU 5 Pseudostellaria heterophylla(each other 14.8% and 24.7%) were highly showed in herb layer. In INSPAN(INdicator SPecies ANalysis) of vegetation units, 33 species were analyzed significantly(p<0.05).
