Coastal forested wetlands are important ecosystems that help store carbon, keep water clean, provide homes for many animals, and protect coastlines from storms and rising seas. However, these wetlands are under threat from climate change, changes in water flow, and how land is used. To help protect them, international agreements like the Ramsar Convention were created. The Ramsar Convention is a global treaty that identifies and helps manage important wetlands around the world. Wetlands are selected as Ramsar sites if they are rare, unique, or important for wildlife, especially during tough times like droughts or migrations. In this study, we looked at how forested wetlands that are Ramsar sites along coasts and tidal areas have changed between 2001 and 2024. We used satellite data from a tool called AppEEARS, which gave us information about vegetation, land cover, and how often areas were burned by fire. Our goal was to see whether these protected wetlands are staying healthy or showing signs of damage. The results of our study help show how well international protection efforts are working. We also identify areas where wetlands may need more attention or restoration to stay healthy in the future.
