Abstract
The vascular plants of the studied area in Keum River lower stream were listed 238 taxa: 74 families, 179 genera, 211 species, 24 varieties and 3 forms. In this, Woody plant were 60 taxa (25.2%), Herb plants were 178 taxa (74.8%) of all 238 taxa vascular plants. Pteridophyta were 4 families, 4 genera, 4 taxa, Gymnospermae were 2 families, 2 genera, 3 taxa and Angiospermae were 68 families, 173 genera, 231 taxa. Based on the list of Korean endemic plant, 2 taxa were recorded; Populus tomentiglandulosa, Forsythia koreana. Specific plant species by floral region were total 7 taxa; Salix siuzevii in class III, 6 taxa (Ainus hirsute, Quercus variabilis, Mallotus japonicus, Plantago camtschatica, Actinostemma lobatum, Sagittaria aginashi) in class I. The naturalized plants in this site were 14 families, 35 genera, 40 species, 2 varieties, 42 taxa and naturalization rate was 17.6% of all 238 taxa vascular plants. Wild plants disturbing ecosystem like Ambrosia artemisiifolia var. etatior have been increasing. So, it needs continuing control and conservation measures on the plant ecosystem.
