  • The flora, distribution area, vegetation structure, annual net primary production, and nutrient uptake of the vascular hydrophytes, hygrophytes and mesophytes were investigated in the wetlands of the Asan-Lake, Chungchongnam-do and Kyonggi-do, Korea from March to October in 1997 to reveal the correlation between the plant community and the lake environment. The flora was composed of 38 families, 89 genera, 106 species, 14 varieties or total 120 kinds of the vascular plants. The life from of the hydrophytes were classified as 14 kinds of emergent plants, 5 kinds of submerged plants, and 4 kinds of free-floating plants, respectively. The number of species was various to 4 ∼85 kinds in each site. The dominant species was Zizania latifolia, and the importance values of Zizania latifolia, Typha orientalis, Phragmites communis, and Spirodela polyrhiza were 39.58, 14.90, 13.97, and 7.64, respectively. The distribution area of the emergent hydrophytes, hygrophytes, and mesophytes was 49.3 ㏊ (90.5%), and free-floating plants was 5.2 ㏊ (9.5%), whereas the floating-leaved and submersed plants were rare. Annual net production of the emergent hydrophytes, hygrophytes, and mesophytes was 547.9 ton D.W./yr (98%), and those of the free-floating plants was 10.5 ton D.W./yr (2%), and 558.4 ton D.W./yr in the whole lake ecosystem. The total uptake of nitrogen and phosphorus by the vascular plants was 7,099 and 1,891 ㎏/yr in the whole lake ecosystem.

  • The flora of vascular plants of these sites were listed 272 taxa; 80 families, 193 genera, 234 species, 32 varieties, 5 forms and 1 hybrid. The naturalized plants were 12 taxa, and naturalization rate was 4.4%. Specific plants by floral region were total 54 taxa; 4 taxa in class IV, 10 taxa in class III, 5 taxa in class II, 35 taxa in class I. There is no taxa in class V. A peculiar point is that we found more than 30 Allium pseudojaponicum in Allium genus which is known as Japanese endemic plant. In Gokdudo, there is large Carex boottiana community, in Daehangdo, Machilus thunbergii community covers the whole island. In Bulgeundo, most of the hundreds of trees including Neolitsea sericea and Machilus thunbergii planted by Korea National Parks in 2003 have been damaged by rabbits.

  • 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.
