%X To find out the status and characteristics of exotic plants in the Gwangreung Forest, arepresentative forest ecosystem in central Korea, we surveyed the species composition, coverage, and habitatilluminance of exotic plant species in a set of quadrats established along roads and trails in and around theGwangreung Forest and buffer zone areas. In 1932, only five species of exotic plants were found along pathsand roads in the Gwangreung Forest. However, the number of species in the forest has dramatically increasedsince 2000, when Ambrosia artemisiifolia L. and A. trifida L. were first recorded, and in 2007, 38 species of exoticplants were recorded. Among the 11 families, 23 genera and 25 species of exotic plants recorded in thequadrats, Compositae was the most common family (11 species), and perennial herbs, 42%, were the mostfrequently occurring life type, followed by annual herbs (31%) and biennial herbs (19%). Plants of NorthAmerican origin comprised 48% of exotic species identified in our surveys. Exotics were found most frequentlyin quadrats along roads in the forest, followed by the buffer zones and hiking trails. The number of species andindividuals of exotic plants decreased as we moved deeper into the forest, but Aster pilosus Willd. and Erigeronannuus (L.) Pers. were identified along hiking trails in the interior, and appeared to be capable of spreadingfurther and more rapidly into the forest than other species.
