Summary

Coastal and estuarian wetlands in the Great Lakes Basin are increasingly impacted by habitat degradation, invasive species, and most recently (late 2010's), increased water levels. These wetlands act as an important buffer between the open lake and the near-shore areas, as key areas for nutrient cycling, as critical nurseries for many species of lake fish, and as habitat for numerous species of concern. Understanding how the cover and composition of these wetlands has changed over time is critical to making informed management decisions. Using both historical documents and imagery we will work to create historic maps of wetland coverage that can be compared over time and to current maps and imagery of these critical wetlands.

Purpose

The objectives of this project were to: (1) create rectified, GIS-ready data layers of the historic wetland maps found in the USFWS publication Fish and Wildlife Resources of the Great Lakes Coastal Wetlands within the United States (Herdendorf et al., 1981) and (2) create rectified, GIS-ready data layers of the current wetland habitat at sites with maps in the noted publication.
