In the last 200 years the Great Lakes region, like many regions in the world, has experienced considerable changes due to human activity. The alteration of biological communities and habitats, fragmentation, introduction of invasive species, and changing climate are potentially the dominant alterations of the physical environment of the Great Lakes region and the waters therein. Restoration and rehabilitation of native species, habitats, and ecosystems is an integral research focus of the Center. The Center will maximize its influence in restoration of the Great Lakes due to its expertise in species biology, community dynamics, and ecosystem processes. The Center will conduct state-of-the-art restoration ecology research that will enable the Great Lakes region ecosystems to be restored to resilient and sustainable populations, communities, and ecosystems with dynamic and unimpaired processes at appropriate scales.
