This study is to offer the basic data for restoration and conservation of wetland ecosystem by surveying and analysing the flora distributed in the Binae marsh, Namhan River, Chungju-si. The flora in the Binae marsh were verified 204 taxa including 48 families, 152 genera, 179 species, 23 varieties and 2 forms. In flora, pteridophyta were 2 taxa including 1 family, 1 genus and 2 species, among angiospermae, dicotyledonae were 153 taxa including 37 families, 110 genera, 138 species, 13 varieties and 2 forms and monocotyledonae were 49 taxa including 10 families, 41 genera, 39 species and 10 varieties. In the result of classifying the life form of flora, megaphanerophytes (M), nanophanerophytes (N) and chamaiphytes (Ch) were each 9 taxa (4.4%), 37 taxa (18.1%) of hemicryptophytes (H), 19 taxa (9.3%) of geophytes (G), 97 taxa (47.6%) of therophytes (Th) and 24 taxa (11.8%) of hydrophytes (HH). The rare plant designated by Korea Forest Service was 1 taxa (Aristolochia contorta), and the endemic plant was 1 taxa (Salix koriyanagi) too. The specific plants by floristic region were 6 taxa. From among these, the species of degree I were 5 taxa including Salix chaenomeloides, Aristolochia contorta, Artemisia selengensis, Cirsium pendulum and Vallisneria natans, and degree III was 1 taxa including Alisma orientale. The naturalized plants were 45 taxa and the invasive alien plants were 3 taxa including Sicyos angulatus, Ambrosia artemisiifolia and Ambrosia trifida. The naturalized index (NI) was about 22.1%, 16.1% of urbanized index (U...
