The purpose of this study was to provide basic data for preserving forest ecosystem with understanding forest wetland condition of Mt. Cheongok. It was found from this research that vascular plants of surveyed area were composed of 72 families, 167 genera, 209 species, and 2 subspecies, 27 varieties, 5 formae. totaling 243 taxa. Among the investigated vascular plants, Korea endemic plants were 9 species, rare plants 15 species, and naturalized plants 8 species, respectively. According to the occurrence frequency within the wetland investigated, obligate upland plants (OBU) accounted for 75.72% (184) among the total species investigated, wherea obligate wetland plant (OBW) were four species (4.65%). There were 26 of hygrophyte plants and 2 of emergent plants in the research area according to wet degree. According to habitat category, the most frequently occurred habitat was forest (136 species, 55.97%), and the others were in the order of meadow and shrubland (70 species, 28.81%), wet meadow (35 species, 14.40%), and aquatic environment (2 species, 0.82%), respectively. In the result of analysis of important value, Fraxinus rhynchophylla and Carex pseudosinensis was the highest as 22.17% and 10.40%. It was confirmed that the species diversity was relatively high. Shannon-Wiener's species diversity index was calculated as 2.507. Based on these results, long-term monitoring survey should be urgently needed for ecological restoration and recovery.
