The Nature Conservancy in Iowa (TNC) was awarded two ecological restoration grants for over $55,000 as part of the Society for Ecological Restoration’s (SER) Standards-based Restoration in Action program in collaboration with Microsoft, to restore two oxbow wetlands. This nature-based solution will reduce flood risk, restore biodiversity, and improve water quality. The restored wetlands are situated along Prairie Creek, an important branch of the Boone River, and located within Kossuth County.
TNC is actively restoring the Boone River watershed and has completed 47 out of 400 potential oxbow restoration projects in the river system. The Boone River watershed has some of the most biologically diverse and healthy freshwater communities in Iowa, and restoring degraded oxbow wetlands also has measurable and lasting impacts on improving water quality. By restoring critical oxbow wetland habitat, TNC is helping address the biodiversity crisis, improve water quality, and provide important flood control benefits in the Boone River Watershed and the greater region.
To date, TNC has worked strategically with landowners along Prairie Creek to restore two degraded wetlands that had become filled in with sediment over the last 70 years. Restoration began by digging five and a half feet down and excavating over 3,000 cubic yards of sediment to reach the historic riverbed. The excavated sediment was thinly spread along the top banks of the oxbow to provide a fertile bed for native plants to be seeded. As part of the project, TNC will work with Microsoft volunteers in the fall of 2023 to restore native plantings on over four acres around the wetlands to help stabilize the soil. “One of the best things about this collaboration is that it supports local organizations like The Nature Conservancy in Iowa and community members, as well as Microsoft employees, to go outside and get their hands dirty restoring their backyard. Well-designed, well-implemented ecological restoration is a positive, empowering, solutions-based approach to local and global challenges. Microsoft’s commitment to standards-based restoration shows they take sustainability seriously,” said SER Executive Director Bethanie Walder.
TNC’s project aims to restore degraded oxbow wetlands in the Boone River Watershed to help capture and filter stormwater runoff and provide critical wetland habitat and native prairie habitat for wildlife. Downstream communities, such as Des Moines, will benefit from reduced flood risk and improved water quality. In addition, this project will improve biodiversity; at least 81 species of birds and 57 species of fish, including the federally endangered Topeka shiner, will benefit from restored oxbow habitat. This specific project will be completed in October 2023. In the years following, we will monitor the restoration site to ensure the wetlands are functioning as planned and to investigate wildlife benefits through fish surveys.
