Wetlands in Quebec, Canada are important for providing ecosystem services, but they are being affected by climate and human activities. A study mapped out these services over time and space in the Yamaska river watershed. By analyzing different indicators, researchers found that the habitat provided by wetlands has been degrading over the past 30 years. Even in the best-case scenario, the ecosystem services are not expected to return to their previous state. This study's approach can help identify areas where action is needed to protect these valuable services.
