This study was implemented to clarify the patterns of plant species richness across forest strata and the relative importance of climatic and topographic factors on the Mt. Huiyang, South Korea. From the vegetation survey of 131 study plots, A total of 202 species belonging to 71 families and 144 genera were recorded. Of these plant species, woody and herbaceous plants were 85(42.1%) and 117(57.9%) species, respectively. In addition, 28, 69, and 173 species were observed in the overstory, midstory and understory, respectively. From the results of the structural equation modeling explaining the causal relationships among biotic and abiotic factors, topographic factor had a negative effect on the species richness of overstory and midstory, but had no effect on the understory species richness. Climate factor showed nonsignificant effect on the species richness across forest strata. Overstory species richness had a significant effect on the midstory species richness. Moreover, midstory species richness had significant effects on total and herbaceous species richness of the understory. We found midstory species richness and topographic factor had more important contributions to the understory species richness than climate factor and overstory species richness. This study suggests that plant diversity in the Mt. Huiyang are controlled by interactions between forest strata as well as abiotic factors such as topographic and climate factors.
