Abstract
This study analyzed on the characteristics of vegetation structure, species composition and DBH class distribution in order to conservation and effective management for Taxus cuspidata community in Mt. Seorak, Mt. Balwang, Mt. Taebaek, and Mt. Odae. The vegetation in upper, subtree and shrub layer was consist of 11, 22, 33 species in Mt. Seorak, 15, 21, 33 species in Mt. Balwang, 10, 23, 36 species in Mt. Taebaek, and 14, 30, 32 species in Mt. Odae. As a result of importance value at all study sites, T. cuspidata and Abies nephrolepis in upper layer, T. cuspidata, A. nephrolepis and Acer komarovii in subtree layer, and Tripterygium regelii in shrub layer were high, respectively. Species diversity in upper and subtree layer at all study sited were ranged 0.834~1.234 and 1.125~1.329, respectively. According to the DBH class of major three species, T. cuspidata in Mt. Odae site showed a reverse J-shaped curve, which was estimated that T. cuspidata community of this site might be maintained continuously as a stable state.
