  • Knowing how many species live in a ecosystem is a major work because of the distributions of species are determined by the environmental condition. This study was carried out to investigate the distribution of vascular plants of Gonggeom-ji, located in Sangju-si, Gyeongsangbuk-do, from April to October on 2012. The vascular plants were summarized as 240 taxa including 69 families, 176 genus, 204 species, 2 subspecies, 29 varieties, and 5 forma. Among the investigated taxa, 3 taxa of Korean endemic plants were included. Based on the list of specially designated plants by Ministry of Environment, 11 taxa including Alisma orientale, Monochoria korsakowii and Nymphoides peltata were recorded. The naturalized plants were identified as 26 taxa and the ratio of naturalized index (NI) was 10.8% of vascular plants recorded. 31 taxa of hydrophytes showed 17.8% of Korea. To conservation of wetlands, we suggest that it is required to minimize for unnecessary disturbance of human and to make a strategy for effective management by continuous monitoring for ecosystem alteration.

  • The objectives of this study were to offer the basic data for the restoration and conservation of forest wetland by surveying systematically the vascular plants of Sandeul wetland in Mt. Jaeyak, Miryang-si, Gyeongsangnam-do, Korea. The vascular plants in this wetland were recorded as 232 taxa; 74 families, 178 genera, 200 species, 27 varieties and 5 forma. The major communities were Quercus mongolica, Tripterygium regelii, Alnus japonica, Molinia japonica, Salix gracilistyla and Stephanandra incisa. The numbers of plant species by routes were 168 taxa in A-route, 126 taxa in B and 132 taxa in C. The ecological problems in Sandeul wetland were the afforestation of Pinus koraiensis and P. thunbergii, the appearance of naturalized plants, the invasion of species and the scour of valley. The Korean endemic plants were 5 taxa; Salix hallaisanensis, Hepatica insularia; Chrysosplenium barbatum, Ajuga spectabilis and Weigela subsessilis. The rare plants designated by Korea Forest Service were 3 taxa; Aristolochia manshuriensis, Chrysanthemum lineare and Iris ensata var, spontanea. The naturalized plants were 8 taxa; Rumex acetocella, R. crispus, Trifolium repens, Oenothera lamarckiana, Ambrosia artemisifolia var. elatior, Helianthus tuberosus, Erigeron annuus and Phleuum pratense.

  • Two naturalized allien species are reported from Jeju Island: Papaver setigerium collected from the ground along the road in lowland Veronica serpyllifolia collected from the roadside and ranches on alt. 400-800 m. P. setigerium is similar to P. somniferum, but different from the latter by plant height of 30-70 cm, shorter discoid stigma than fruit in diameter, somewhat sparsely bristly on stems, leaves and calyxes. V. serpyllifolia is similar to V. tenella in morphology, but different from the latter by short plant height, petiolated leaves on lower stem and serrated leaf margins.

  • This study was carried out to investigate the distribution status and UI(urbanization index) of the naturalized plants and exotic plants. For this purpose 7 cities and counties in the northern South Jeolla Province were selected and investigations were conducted on a total of 14 sites, two sites from each city or county, during the period of March to November 2006. The exotic plants were identified as 111 taxa; 26 families, 79 genera, 105 species, and 6 varieties. As for urbanization index, Hampyeong County had the highest level of urbanization(21.95%) and Gokseong County the lowest level of urbanization(16.38%). Naturalized plants classified as family were as follows: Compositae was 36 kinds(32.43%) Graminae 17 kinds(15.31%) and Leguminosae 7 kinds(6.31%). Major communities of naturalized plants consisted of 21 communities including Robinia pseudoacacia-Amorpha fruticosa community, Erigeron annuus community, Erigeron canadensis community etc. Invasive naturalized plants consisted of 7 taxa: Paspalum disticum var. indutum, Paspalum distichum, Rumex acetocella, Solanum carolinense, Aster pilosus, Ambrosia artemisiifolia var. elatior and Ambrosia trifida. The study shows that the integrated management of exotic plants on a national scale is needed. It also recommend that a systematic and integrated management of exotic plants in the northern South Jeolla Province is crucial to preserve and protect natural species.
