Beavers can engineer riverbeds into promising ways to prevent carbon dioxide release into the air. They are increasingly returning to rivers and other natural landscapes across Europe and can dramatically reshape how carbon is stored, cycled, and retained in headwater stream systems–the small, upstream beginnings of rivers. By building dams, they flood stream margins, create wetlands, alter groundwater pathways, and trap large amounts of organic and inorganic material, including carbon.
