Vegetation Structure around Natural Trails in Mt. Jiri National Park

This study was conducted to provide basic information for effective management strategies on nature trails in Mt. Jiri national park. Vegetation structure of nature trails in Yupyeong, Jungsanri, Hadong and Baekmudong districts was researched to accomplish the purpose of study. The tree and subtree layer consisted of 16 and 11 species for Yupyeong, 14 and 16 species for Jungsanri, 10 and 13 species for Hadong, and 19 and 10 species for Baekmudong district, respectively. The importance value of Quercu variabilis in the tree layer was highest for Yupyeong, Jungsanri and Baekmudong districts, and that of Pinus densiflora was highest for Hadong district. The herbaceous layer was composed of 70 species for Yupyeong, 53 species for Jungsanri, 65 species for Hadong, 57 species for Baekmudong districts, respectively. The value of species diversity ranged from 0.752 to 1.162, 0.957 to 1.085 and 1.283 to 1.506 at tree, subtree and shrub layer, respectively. Evenness ranged 0.752 to 0.983 at all layers for four nature trails in Mt. Jiri national park.
