Community Structure and Understory Vegetation Distribution Pattern of Fagus engleriana Stand in Is. Ulleung

This study was conducted to investigate the changes understory vegetation composition (shrub and herb layers) in Mt. Gyebang as a northern-temperate deciduous broadleaf forest. Tracheophytes were 146 taxa, consisting 56 families, 93 genera, 124 species, 17 varieties, 3 forma, 2 sub-species and 1 unknown taxa in research subject area. As species area curve analysis, herbaceous layer and shrub species have been decreased over time. As a result of Mantel-test, basal area of upper layer affects to understory vegetation change (p<0.0001). Mean importance value was dominated Lindera obtusiloba (21.585%), Rhododendron schlippenbachii (19.774%) in the shrub layer, identified Sasa borealis (14.082%) and Lindera obtusiloba (7.921%) in the herb layer. According to NMS analysis of shrub layer, Species characterized by strong correlation have been reduced as time goes by. And it reports different species as an increasing in basal area of the upper layer. Herb layer plots of the NMS analysis, Rhododendron schlippenbachii and Rhododendron mucronulatum consistently were affected in shrub layer. In consequence of MRPP-test for changes in vegetation composition, It was analyzed that there are no significant differences for vegetation composition changes on shrub layer in 5-10 years. As a changes of vegetation composition on herb layer were analyzed significantly, composition change of herb layer species was larger than shrub layer species in understory vegetation.
