The Bukhansan National Park's Uiryeong Trail, connecting Seoul and Yangju, has been closed since 1968 but opened on weekdays starting March 2024. This change has drawn attention to the potential ecological impacts on the long-restricted area. Due to its status as a military-controlled zone, there has been limited ecological research conducted. Vegetation surveys centered around the Uiryeong Trail were conducted, setting up 41 survey plots. The vegetation analysis results were classified into four communities: Quercus mongolica-Castanea crenata community (I), Q. mongolica-Conifer mixed community (II), Q. mongolica-Acer pseudosieboldianum community (III), and Deciduous broad-leaved mixed community (IV). Analysis of each community's vegetation suggests a gradual succession toward a mixed deciduous broad-leaved community centered around Q. mongolica. Management plans propose promoting the spread of native species centered around Q. mongolica and stabilizing the vegetation of Pinus densiflora communities and disturbed Quercus spp. communities to enhance biodiversity.
