This study was conducted to classify community types and identify the structural and environmental characteristics of each classified community in five island regions with evergreen broad-leaved forests: Jeju-Province, Ulleung-do, Heuksan-do, Hong-do and Wan-do. Field surveys were conducted from 2020 to 2024 using phytosociological methods, encompassing a total of 143 survey plots, and the collected data were classified into community types through cluster analysis. As a result, four community types were identified: the Machilus thunbergii community(Mt), Quercus glauca community(Qg), Castanopsis sieboldii community(Cs) and Quercus acuta community(Qa). Based on the importance values of the classified communities and their stratification structure, it was determined that the current structure is likely to be maintained in the near term across all communities. However, In the sub-tree layer and shrub layer, tree species such as M. thunbergii, Litsea japonica and Camellia japonica were engaged in stratification competition. Therefore, long-term monitoring of competing species is deemed necessary to understand the successional processes of the evergreen broad-leaved forest stands. Species diversity was found to be higher in the Q. glauca community compared to other communities, and this was attributed to its location in valley areas. The Q. glauca community, characterized by its canopy stratification height, showed relatively high light transmittance, leading to greater species diversity in the lower layers. And there were statistically significant differences in three environmental factors—altitude, aspect and latitude—among the communities. Therefore it was concluded that these factors should be considered when selecting tree species for the restoration or afforestation of evergreen broad-leaved forests in the warm-temperate region especially in South Korea.
