This study examined the feasibility to develop wetland OECMs in wetland inventory sites in South Korea. The study applied the National Institute of Forest Science & National Arboretum (2024) forest OECM evaluation criteria to the wetland inventory sites. Six of the seven criteria were deemed met. Furthermore, given the diverse stakeholders identified in the Criterion 7, efforts are needed to ensure fairness in governance and management. If these issues are addressed, an area of 660.99 km2 within the wetland inventory sites could be developed as wetland OECMs. This would significantly contribute to achieve the GBF target to designate 30% of the national land area as protected areas.
