Our research team builds new tools to integrate spatial information for environmental management decisions in the Great Lakes. We aim to build maps to visualize and understand environmental impacts (or stressors ) on the lakes and benefits humans enjoy from the lakes (or ecosystem services ). For example, we developed this high resolution map of cumulative ecosystem stress to guide restoration, conservation, and management efforts. This map merges data for all major categories of environmental stressors  to the Great Lakes, ranging from climate change to pollution to invasive species. We invite you to explore this interactive map using the pan and zoom tools in the upper left corner, and to browse all of the other information and maps on our site.
