Wetlands along Wisconsin’s Great Lakes coast are unique habitats at the transition between watersheds and the larger lake. Watch the video below to hear Wisconsin Sea Grant fisheries specialist Titus Seilheimer discuss Wisconsin’s coastal wetlands—diverse wetland ecosystems that provide many functions, including shoreline protection and nutrient and sediment filtration. These wetlands also provide important spawning and nursery habitat for many fish species: Great Lakes coastal wetlands play an important part in the life history of more than 70% of Great Lakes fish species. Physical habitat in coastal wetlands is greatly influenced by changing water levels, from short term changes that are driven by wind to the longer term trends in water level caused by regional climate patterns. The combination of natural variation and human-caused disturbances have dynamic and complex influences on the fish habitat of Great Lakes coastal wetlands.
