The Great Lakes Restoration Initiative
• Established in 2009 to accelerate efforts to protect and restore the Great Lakes
• Has invested roughly $2.3 billion in restoration projects to date
• Provides resources to tackle sites of some of the most significant contamination in the country
• Five major focus areas
➤ Toxic Substances and Areas of Concern
➤ Invasive Species
➤ Nonpoint Source Pollution Impacts on Nearshore Health
➤ Habitats and Species
➤ Foundations for Future Restoration Actions

Model Development
The goal of this project is to develop
tool capable of calculating the value of
incremental changes in ecosystem
services.
The tool is based on a series of nested
ecosystem models and benefit transfer
functions.
The tool will be applicable to all 14
Areas of Concern in Michigan.
Estimate Economic Value of Change
Determine Change in Ecosystem Services
Model Effect on Environment
Identify Management Action

The project team developed causal loop diagrams for major
ecosystem services including: water quality, recreation, fish
and wildlife populations, and human health

A 2017 study by researchers at Grand Valley
State University found that property values near
Muskegon Lake increased by $11.9 million as a
result of environmental restoration
This accounts for just one component of
ecosystem service value
