Invasive species pose a threat to culture around the Great Lakes region. The Grand Portage Band of Lake Superior Chippewa rely on traditional practices to sustain themselves. Sea Lamprey kill the lake trout that tribal fisherman rely on; Sweetgrass, used in ceremonies and for weaving, is overtopped by invasive plants; and aquatic invasive plant species crowd out the Wild Rice that the tribe gathers every year. Despite these threats, the Grand Portage Band and the National Park Service are working to successfully manage the ecosystem and keep cultural practices intact. This video is part of Little Things: big Problems, a series of 5-minute online videos on invasive species in the Great Lakes region that we produced for the National Park Services’ work in association with the Great Lakes Restoration Initiative. The series won a first place Gold Screen Award in the new YouTube category of the National Association of Government Communicators' annual award competition.
