분홍장구채(Silene capitata)의 국내 분포 현황과 생태 특성 연구 = Study on the Distribution and Ecological Characteristics of Silene capitata in Korea

다국어 초록 (Multilingual Abstract)

This study aims to support conservation efforts for Silene capitata, a class II endangered wildlife species in South Korea, by identifying its domestic distribution, habitat characteristics, and key threats to its population. Data on the distribution and ecological characteristics of S. capitata were gathered through literature review and field surveys and recorded in survey forms for Yeongwol, Hongcheon, and Cheorwon in Gangwon Province; Yeoncheon in Gyeonggi Province; and Okcheon in Chungcheongbuk Province. An IUCN threat assessment was conducted to quantify and classify specific threats impacting the species. S. capitata were observed in substantial numbers in Hongcheon and Yeoncheon, primarily inhabiting rive cliffs and rocky mountain habitat, where they were frequently located on east- to south-facing slopes with high solar exposure, subject to significant drought stress. The threat assessment identified rockfalls and landslides as principal threats intrinsic to the habitat; however, the main drivers of population decline included alterations in light conditions due to rockfall protection net installations, the expansion of vine species, invasion by native competitors (e.g., Selaginella rossii), and climate change-induced river flooding. Based on these findings, we recommend site-specific conservation strategies for S. capitata, including habitat management, removal of competing vegetation, prevention of habitat alteration from artificial structures, and ongoing population monitoring. This study provides critical data for the conservation of S. capitata and contributes to the development of long-term management strategies for legally protected species in South Korea.
