Last year the National Park Service produced a series of short documentaries exploring invasive species in the Great Lakes. The series was funded by the Great Lakes Restoration Initiative showing how invaders are changing the ecosystems in national parks and what’s being done to stop them.
All four of them are available through the Great Lakes Echo. Part 1: Aquatic Invasives is below and it explores how zebra mussel, quagga mussel, round goby and other invasive species are creating havoc in Lake Michigan, causing the food web to tilt out of balance. People can help, clean drain and dry all boating and fishing gear to stop aquatic hitch hikers. here’s Part 2: Invasive Plants in our Parks, Part 3: Spotted Knapweed, and Part 4: Emerald Ash Borer!
