Lunch & Learn: Saving the Winged Mapleleaf Mussel from Extinction

Did you know that the St. Croix National Scenic Riverway is home to more than 40 species of freshwater mussels? These mussels play a critical role in maintaining the excellent water quality of the Namekagon and St. Croix river system by filtering water and cycling aquatic nutrients. But one genetically unique species, the winged mapleleaf, is close to extinction.  Wild Rivers Conservancy and our invaluable partners are engaging in cutting-edge research in our National Park to save this mussel.

Join Michelle Bartsch, a Research Biologist with the US Geological Survey, Upper Midwest Environmental Sciences Center, to learn more about the science and methods being developed right here in the St. Croix watershed to save this endangered mussel.
