This study was carried out to investigate the vascular flora at Geonjisan, Jeonju, Jeollabuk-do and the findings are followings (1) The vascular plants identified and surveyed were 359 taxa(306 species, 49 varieties and 4 forms of 245 genera of 94 families) at the study sites. (2) There were 144 taxa (125 species, 15 varieties and 4 forms of 91 genera of 49 families) for the woody plants, while 215 taxa(181 species and 34 varieties of 157 genera of 54 families) were identified for the herbaceous plants. Twenty-nine taxa (28 species and 1 variety of 22 genera of 12 families) were investigated for the naturalized plants at the study sites. (3) Currently existing dominant vegetation forming the major trees layer at the study sites were Robinia pseudoacacia, Chamaecyparis pisifera, C. obutusa, Torreya nucifera, Castanea crenata and Acer buergerianum for the planted species, and naturally growing species forming the major trees layer were Quercus acutissima and Q- serrata.
