  • 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.

  • 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.

  • 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.

  • This study was carried out to investigate the flora of Mt. Suan (Gyeonggi-do). The vascular plant were collected 13 times (from March to October 2011), and 402 taxa in total were identified, including 102 families, 274 genera, 354 species, 6 subspecies, 40 varieties and 2 forms. Among them, 8 taxa of Korean endemic plants and the Korea Forest Service-designated rare plants were identified as 5 taxa. Based on the list of plants which have been approved for overseas delivery, 10 taxa were recorded in the investigated area. The Ministry of Environment-designated specially plants were identified as 17 taxa. The naturalized plants were identified as 41 taxa and the percent of naturalized index (NI) was 10.2% of total 402 taxa vascular plants.

  • The flora of vascular plants in Geojedo revealed to be 550 taxa based on only the voucher specimens to be collected. It comprise 108 families, 341 genera, 478 species, 69 varieties and 3 forms respectively. Among them, 13 taxa of Korean endemics and 8 taxa of rare and endangered plants were investigated in addition to 75 taxa of specially designated plants announced by the Ministry of Environment. Furthermore, 36 taxa of induced and naturalized plants were also observed in this area. One of the characteristics of forest vegetation is the broadly occupation of Pinus thunbergii on whole area of Geojedo. Although it's well condition and conservation status, the destruction area of vegetation was rapidly increasing by the industrial development, the deforestation and the tramp as well as by the basic disturbances of human beings. Therefore, more active and positive conservation strategy such as expansion of conservation area should be prepared rapidly by the results of long-term monitoring studies.
