About this Collection

The U.S. Fish and Wildlife Service (Service) works to provide the foundational information necessary for the strategic management of our nation's wetlands.

The Service is the federal agency responsible for mapping the nation’s wetlands and providing the data to the public through the Wetlands Mapper.   

The Service’s decadal wetland Status and Trends reports provide estimates of U.S. wetland extent, type, and change from the 1700s to 2019.  These reports inform policymakers and the public on the status of the nation's wetlands and identify threats.  

The Service’s annual Waterfowl Breeding Population and Habitat Survey uses continental-wide aerial surveys to provide abundance estimates and wetland habitat conditions for management of duck species, Canada geese, American Coot and swans. The surveys are used in waterfowl production models to establish catch limits for hunters.  

The Migratory Bird Joint Ventures are Service-supported regional partnerships that use cutting-edge conservation science for protecting and restoring species and wetlands and other habitat across the United States and Canada.  

The Habitat and Population Evaluation Team monitors wetland habitat and develops population forecasts for waterfowl, other migratory birds as well as pollinators and threaten and endangered species that depend on wetlands. These tools are used to manage wildlife by Service refuge managers and Joint Ventures in the Prairie Pothole Region, which includes parts of Minnesota, Montana, Iowa, North Dakota, and South Dakota.
