South Korean authorities are intensifying management and control strategies to combat the spread of pine wilt disease. Nationally, the number of damaged trees has risen significantly, with Gyeonggi Province reporting 116,665 infected trees following a 67.8% surge. In Gwangyang, over 33,000 trees are reported as infected, while Gapyeong County has seen damage escalate from 4,591 trees in 2021 to 72,507 last year, severely impacting local pine nut production. To address resource management, the Korea Forest Service and Chungcheongnam-do are establishing an ‘industrialized prevention system.’ This initiative aims to transform damaged timber into high-value products, such as sawn timber and boards, before using remaining materials for fuel. To prevent disease spread during transport, the plan utilizes mesh-covered boxes and 14-day fumigation processes. Regional responses are becoming more specialized. Chungcheongnam-do is developing a ‘Chungnam-style control strategy’ to move beyond simple tree removal toward systematic management based on regional forest conditions. Several areas, including Boryeong and Gapyeong, are being designated as special prevention zones to allow for year-round control measures like preventive injections and species conversion. In Gapyeong, a species conversion project is currently 60% complete, aiming to replace damaged Korean pines with more resilient species. As the crisis scales, local leaders are calling for increased central government support. Gapyeong County Mayor Seo Tae-won has proposed raising the national subsidy for forest disaster countermeasures from 50% to 70% to alleviate the rising financial burden on municipalities. In response to recent outbreaks, Seoul Mayor Oh Se-hoon has ordered a comprehensive response to ensure no infected trees remain in the city after 74 infections were identified across districts such as Gangdong and Seongbuk. The city is shortening the preventive medicine injection cycle from three years to two and deploying drones for surveillance in hard-to-reach areas.
