Great Lakes Health
The Great Lakes are a globally important natural resource. They represent approximately 20 percent of the world’s fresh surface water and provide habitat for over 100 species of globally rare plants and animals. Additionally, 42 million people depend on the Great Lakes for their drinking water. Unfortunately, the ecological integrity of the lakes is significantly stressed. Within the past few decades, chemical and microbial contamination and the introduction of invasive species have led to the decline of native fish and wildlife populations and degradation of water quality and habitats. IISG works with community leaders, natural resource professionals, and Great Lakes residents to monitor, improve or protect the quality of the Great Lakes overall and in critical locations.

Initiatives
Lawn to Lake
Lawn and garden chemicals applied in the Lake Michigan basin can wind up in the water, polluting the lakes with pesticides and excess fertilizer. The program promotes healthy landscape practices, offering communities, landscapers, residents, and others, tips for maintaining healthy lawns and landscapes without over-relying on chemicals.
SOLEC
The State of the Lakes Ecosystem Conferences and State of the Great Lakes reports are produced by the U. S. EPA and Environment Canada to provide independent, science-based reporting on the state of the health of the Great Lakes basin ecosystem.
The Great Lakes Legacy Act
This 2002 congressional act authorizes funding to remove hundreds of tons of contaminated sediment that has built up over the years and left some local waterways severely polluted.
River Restoration: Concepts and Practices
This workshop series brings together experts from around the United States and Canada to discuss the successes and failures of current river restoration technologies.
Got fish and aquatic plants? Get a Habitattitude™
Aquarium and water garden enthusiasts can help prevent the introduction of invasive species into local waters by choosing alternatives to releasing plants and animals into the wild.
