We performed the floristic study of Carpathian mountains in Ukraine from April 2008 till October 2009. We designated eight important areas to investigate in Ukraine Carpathians including Svydovets, Chornohora, Kuziy-Trybushany, Maramorosh, Uholka-Shyrokyi Luh, Narcissi Valley, Chorna Hora, and Yulivska Hora. The total numbers of vascular plants in investigated area were 1,349 speices from 502 genera and 112 families. The endemic species to Carpathians numbered to 65 from 49 genera belonging to 24 families, and it was corresponded to 4.8% of the 1,349 vascular species. We prepared the list of vascular plants with compiling database on useful plants. Ukraine Carpathians endemic species could be applied as high value products in research and practice. Moreover, the flora of Carpathian mountains which is distributed in five nations in eastern Europe and famous for Primeval Beech Forests (Fagus sylvatica), is useful to compare the floristic study with Korean flora.

The analysis of seven islands in Gogunsan archipelago, Korea with insect fauna and vascular plant flora was carried out based on a field survey conducted in May, July, and September. As a result, a total of 2,817 insect individuals including 264 species and 315 taxa of vascular plant were recorded. Bangchukdo the largest island among the seven islands showed the largest number both insect species and plant taxa. The similarity analysis suggested that the nearness of each island strongly affected the insect fauna and vascular plant flora on each island. In addition, there was significant correlation between the areas of each island and the numbers of insect species (Spearman's correlation coefficient=0.857, P-value=0.014). In the future, the results of this study can be used as data related to island ecology and conservation.

A vascular flora survey was conducted in 2020 to identify flora and analyze changes in the numbers of vascular flora species over the past 10 years at Gongju-weir (GW) and Baekje-weir (BW) in the Geumgang River, Republic of Korea. A total of 241 taxa were found in GW and 279 taxa in BW, and 208 taxa (88% of total taxa) were common species. The distribution of invasive species in GW and BW were seven and eight taxa, respectively. Rare plants were not identified in any of the weirs. The Poaceae family dominated in terms of number of species, followed by Asteraceae, Legumes, Cyperaceae, and Polygonaceae. Additionally, Therophytes accounted for a high proportion of Raunkiaer life forms. The numbers of vascular plant species, total taxa, naturalized plants, and invasive species have been increasing over the last 10 years. However, long-term alterations in invasive species before and after the opening of the weirs increased much more significantly in the partially opened BW than in the fully opened GW. These results indicate that the degree of barrier opening does not affect the invasion and establishment of non-native species.

This study has been conducted to understand the relationships such as interspecific interactions between species and landscapes within and outside of agricultural land by identifying the flora features of Cornus officinalis farmlands in Gurye which designated as Korea's Important Agricultural Heritage System. For this, the flora of vascular plants was surveyed in every land uses of two representative districts. These two districts represent the own features of Cornus officinalis farming area which including land uses like forests(especially pine tree), valley, farmland(rice paddy, farms, Cornus officinalis farmland), and residence. Also differences in flora by stone wall's existence and Cornus officinalis's DBH were surveyed. As a result, Cornus officinalis farmlands showed the various vascular plants than the other land uses. According to the existence of stone wall in Cornus officinalis farmlands, there were no differences in appearance flora. But the flora in Cornus officinalis farmlands which have different Cornus officinalis' DBH(Divided into average over 15cm and under 8cm), various plants were showed in average over 15cm than average under 8cm. In conclusion, Cornus officinalis farmlands have been actively engaged in various types of land use and species exchanges, including forests, valleys, villages, and fields, and it has been confirmed that it acts as an ecological axis connecting forests to villages.

Flora and distribution of vascular hygro- and hydrophytes were investigated from April to June, 1983 on the seven sampling sites along the estuary of Nagdong River. As the result, total 60 kinds of vascular plants are investigated, among them 13 kinds are aquatics; Rotala indica var. uliginosa, Myriophyllum spicatum, Allisma canalicultum, Vallisneria asiatica, Hydrilla verticillata, Potamogeton berchtoldii, P. crispus, Ruppia maritima, Phyllospadix iwatensis, Zostera marina, Juncus effusus, Phragmites communis, and Scirpus triqueter. Present hydrophytes are largely confined to the main-stream zone. The transition zone is poorly habitated by hydrophytes and considered for the distributconfined to the estuary and coastal zone. However, long-term conditions of salinity gradient appear to be primarily responsible for the present flora and distribution.

The flora of vascular plants in Jangsanbong located at Busan Metropolitan City was investigated from April 2003 to April 2004. Vascular plants in the surveyed area were 254 taxa that belonged to 78 families, 175 genera, 218 species, 34 varieties, and 2 forma. Among them, 20 taxa of evergreen broad trees, 31 taxa of naturalized plants were identified, and especially Rubus trifidus was first recorded in Busan. In the upper part of a circular road dominant species was Pinus thunbergii. In the lower part of a circular road and the coastal area, dominant species were Platycarya strobilacea, Clerodendron trichotomum, Euscaphis japonica, Quercus aliena, Quercus dentata, Mallotus japonicus, which distribute mainly in the subtropical and temperate zone. In the surveyed area, the canopy consistsed of tall trees, Pinus thunbergii, and the understratum were trees such as Eurya japonica, Ficus erecta, Ligustrum japonicum, Prunus sargentii, and Celtis sinensis var. japonica.

The investigation was made on the relationship among vegetation, net productivity, regrowth and soils of Moonheri-Wasoori, Soodowon-Sungilkyo and Mt. Kumhak grasslands in Chulwon area. The following conclusions have been made as the results of this study. The vascular flora of the grassland in Moonheri-Wasoori was composed of 102 species, the most of which were Medicago denticulata, Miscanthus sinensis, Arundinella hirta, Festuca ovina and Cassia nomame. The flora of Soodowon-Sungilkyn grassland was composed of 74 species, the most of which were Arundinella hirta, Miscanthus sinensis, Carex nanella, Festuca ovina and Cassia nomame. It of Mt. Kumfiak grassland was composed of 78 species, the most of which were Arundinella hirta, Carex nanella, Festuca ovina, Miscanthus sinensis and Aster scaber. These five species contributed greatly to the standing crop of live material which was in excess of 60% of it. The peak standing crop of each 413.7, 307.6 and $348.7g /m^2$ in Moonheri-Wasoori, Soo- dowon-Sungilkyn and Mt. Kuruhak grasslands wars reached in August under flooded conditions as a result of the growth of dominant species, Medicago denticulata and Arundinella hirta. The net prodution of organic matter was slight in some intervals but occurred throughout the growing season After cutting of grasses, the regrowth of new leaves mainly depended on growing stage and edaphic factors. Characteristics of the natural grassland soils, especially, concerning water, total nitrogen, avail-able phosphorus and exchangeable calcium were clarified and might be depend upon the quantity of plant production. Nitrogen, phosphorus and calcium concentration of leaves of Medicago denticulata, Arundinella hirta and Miscanthus sinensis were higher than of stems. Even if diem we diffurmem in the a-mb of nutrients among Medicago denticulata hirta and Miacanthus sinensis for single species and stands. they were covered by variations within species in the present survey. Key words: Competition, Production, Productivity, Regrowth, Soil Properties, Vascular Flora.
