The Apostle Islands National Lakeshore is a collection of isolated islands in Lake Superior. Its natural beauty brings thousands of people to kayak, bird watch, sight see, camp, fish, and hike. With these recreationist also comes the potential to introduce non native plants and animals to new places. One plant of major concern is spotted knapweed. It is a beautiful purple flower, but prevents other plants from growing nearby. It is moved accidently from one island to another by seeds stuck to people and their gear. The National Park Service works hard to control its spread, but needs your help. Keep your gear clean, especially when moving from one trail to another or from island to island.
