After 10 Years, Great Lakes Monitoring Program Still Adapting

The public knows much more about Great Lakes coastal wetlands than it did ten years ago.  In those ten years, the information gathered through the Great Lakes Coastal Wetlands Monitoring Program has led to and supported dozens of advances in Great Lakes science while helping nail down the shifting nature of ecosystem health for a vital part of the Great Lakes system. “I probably get one or two requests for information a week,” Don Uzarski, director of the program, told Environmental Monitor. The program’s most recent semi-annual report lists 40 scientific publications using the collected data. In addition, the data has been used in even more restoration projects, graduate theses and presentations.

Protecting Endangered Species: Conducting Mussel Surveys

*This is part two of a two-part story on endangered mussels. To read part one, click here * With over 300 endangered mussel species in the United States, environmental agencies like EnviroScience rise to the challenge of protecting these vital species. When new construction sites are determined, the Endangered Species Act steps in to protect any endangered wildlife within the impacted area. Unfortunately, the protocols surrounding these protections can be complex and difficult to understand, making the work of scientists like Greg Zimmerman, Corporate Vice President for EnviroScience and an endangered mussel surveyor, vital to protecting biodiversity.

Protecting Endangered Species: Why Freshwater Mussels Matter

*This is part one of a two-part story on endangered mussels. To read part two, click here * Though few people pay any mind to the occasional “clam” shell spotted along a river bank or lake, these small but mighty creatures are deeply important to water systems across the United States, and many of them are federally and state endangered. Greg Zimmerman of EnviroScience, Inc.  shares, “We have about 300 species of mussels in the U.S., compared to other regions of the world like Europe that have under 20 species.” Zimmerman spent his life around water and always knew he wanted to return to help protect aquatic ecosystems. “I’ve always had a love of water, since I was 2. I grew up on an island in Buckeye Lake in Ohio.
