Wisconsin turned harbour dredge into habitat; rare plovers returned after 49 years

Conservationists in Wisconsin have reached an important milestone in Great Lakes wildlife restoration after a pair of piping plovers was found nesting on Wisconsin Point in Superior. The discovery ends a 49-year absence of nesting piping plovers at the site. According to an official announcement from the Wisconsin Department of Natural Resources (DNR), the endangered shorebirds nested in the St. Louis River estuary during the summer of 2026. Wildlife officials had not recorded breeding piping plovers at the site since 1977. The return of the pair follows a large environmental project that turned harbor sediment into new habitat for vulnerable bird species.Creating a new sanctuaryThe breeding pair built its nest on an isolated stretch of sand and cobble created through a $4.5 million habitat restoration project. In 2019, engineers moved more than 87,000 cubic yards of clean sediment dredged from the shipping channel in the Duluth-Superior Harbor.
