Tens of millions of dollars have been spent on tidal wetland restoration over the past several decades but there is still limited information on the long-term ecological outcomes of these efforts. To address this, a collaborative research project worked with four west coast NERRS and regional partners to assess marsh elevation capital, vegetation communities, and carbon sequestration in 16 decades-old restoration sites and paired reference marshes in California, Oregon, and Washington. By investigating how restoration has affected key wetland attributes at some of the oldest restoration sites along the west coast, this project brings actionable information to restoration practitioners and others planning for, designing, and quantifying benefits of new tidal wetland restoration projects. In this webinar, the project team discusses their results, the implications of their findings for future restoration implementation and monitoring, and next steps.
