Recently, monitoring ecosystem changes due to climate change and responding with data-driven strategies are increasingly important. Although Korea has conducted some ecosystem change studies, such as national long-term ecological research, the scale remains limited compared to advanced international efforts. With this in mind, building research infrastructure by benchmarking advanced cases and conducting standardized, comprehensive long-term observations is essential. Therefore, this study established the concept and function of the national ecosystem observation network, and presented a construction plan. Considering the application implications through overseas case studies and domestic conditions, five observation sites would be appropriate. A Korean ecosystem observation network tailored to domestic conditions should be established, comprising comprehensive, general, and mobile ecological observation stations. Lastly, linking this data with existing ecological research and integrated information systems with an own data portal will enhance data utilization, supporting policy development and international cooperation on climate issues.
