This study is carried out to offer the raw data for conservation and management of tidal flat ecosystem by surveying and analysing the flora distributed in Daesong tidal flat wetland, Ahnsan-si, Gyeonggi-do coast, Korea. The results of surveying the flora were recorded as 186 taxa including 45 families, 121 genera, 170 species, 14 varieties and 2 forms. The halophytes checked around this site were 20 taxa including Atriplex gmelinii, Salicornia europaea, Suaeda glauca, Suaeda japonica, Phragmites communis, Carex scabrifolia and so forth. Polygonum bellardii that species had ecological value was the specific plant by floristic region. The growth locations of halophytes were 11 taxa of upper, 4 taxa of high tide line and 5 taxa of lower. The naturalized plants were 42 taxa including Phytolacca americana, Chenopodium glaucum, Melilotus alba, Veronica persica, Bidens pilosa, Leptochloa fusca and so forth. Because Aster subulatusand Leptochloa fusca grew a upper tidal flat wetland, they had the characteristics of halophytes. The focuses on the management of Daesong wetland were halophytes and naturalized plants. Firstly, to maintain a halophytes communities, we will sow the halophytes seeds and plant the individuals. And In-Situ conservation was applied to Polygonum bellardii habitat. Secondly, to prevent the genesis of naturalized plant, we will don't disturb around the wetland environment. The invasive alien plant, Lactuca scariola, was removed by periodic monitoring and purification activity. |
