Marshes for Maine’s Future used an innovative Collaborative Learning approach to facilitate the application of geospatial tools developed by USGS to marsh projects in Maine. The tools provide a scientific framework for supporting decision-makers who actively research and manage climate-induced changes in marsh resilience and vulnerability. The project team developed a series of virtual and in-person knowledge sharing workshops where the USGS creators of the geospatial products could interact with salt marsh professionals working on marsh resilience projects that could benefit from applying the tools. Applying the geospatial tools during these workshops contributed to work protecting, restoring, and managing Maine’s salt marshes.
