The flora of Mt. KumJung(801m) was investigated to compare the flora of Mt. Hwang-Ryung, Mt. Cheon-Hwang, Mt. Chuiseo. The vascular plants, collected from March 1995 to Oct., 1996, were consisted of a total 564 taxa; 103 families, 312 genera, 493 species, 1 subspecies, 66 varieties and 4 forms. The Korean endemic plants of this area were 11 taxa, the alpian and endangered plants were 29 taxa, the special wild plants designating by Environmental Agency were 2 taxa and the alpian plants were 18 taxa. Because many plants, being necessary to conserve, are distributed KumJung, but if development is indespensable, destruction of natural ecosystem must be minimized.
