Warm-temperate evergreen pterophytes of Korea

Korean evergreen fern species that prefer warm-temperate forests as their main habitats are categorized into three groups according to their present distributions: group I, tropic-originating species; group II, Himalaya-originating species; and group III, endemic to warm-temperate regions of Northeast Asia. Due to global warming, a northward expansion of the species belonging to the group III is expected. New habitats of rare evergreen ferns, Crepidomanes latealatum and Haplopteris flexuosa, were found on the Haenam Peninsula, expanding their known Korean habitat from Jejudo Island.
