The land and aquatic habitats surrounding the headwaters of Lake Superior’s largest U.S. tributary, the St. Louis River, now enjoys new protection. The Nature Conservancy of Minnesota (TNC) recently acquired 7,464 acres of undisturbed woodlands and peatlands, known as the Sand Lake/Seven Beavers Preserve. The area is home to one of Minnesota’s largest areas of lowland conifers and rare plants such as Michaux’s sedge. TNC will permit traditional local recreation to continue as it works with Blandin Corporation to develop a forest management plan. The acquisition has been added to TNC’s other preserve in Northeastern Minnesota, 2,000 acres of northern hardwood forest in the Lake Superior Highlands along the Upper Manitou River.
