Impact of Invasive Species

The introduction of invasive species has had a profound impact on the Lake Michigan ecosystem. These species have competed with native species for resources, leading to a loss of biodiversity and disrupting the delicate balance of the lake’s food web. For example, sea lampreys have been known to attack native predator fish, while zebra and quagga mussels have changed the nutrient distribution in the lake, affecting native species.

Conservation Efforts

Recognizing the importance of preserving the natural beauty and ecological integrity of Lake Michigan, various organizations and government agencies have implemented conservation efforts to protect the lake’s native species and manage the impact of invasive species. Some of these efforts include:

  • The Great Lakes Compact, signed in 2008, which protects fresh water as a resource and requires agreement among states and provinces bordering the lakes for any water withdrawals or diversions.
  • The work of organizations like the Alliance for the Great Lakes, which aim to keep the lakes clean and promote strategies to protect native species.
  • Partnerships between multiple organizations to restock Lake Sturgeon and other native species.

Tourism and Engagement

Lake Michigan’s diverse animal species offer a wealth of opportunities for tourism and engagement. Activities like fishing, boating, and educational tours allow visitors to experience and learn about the lake’s marine life firsthand.
