Minnesota has saved its most prized natural landmarks — towering old growth pines, dramatic waterfalls, pockets of native prairie — by protecting them within the state parks system.
Yet the water bodies that define the Land of 10,000 Lakes face the most immediate threats from warmer temperatures and invasive species. Aquatic biologist Peter Sorensen is floating an idea to protect Minnesota’s true gems: the state’s lakes.
