Wetland Distribution

Northern Region Wetlands

In the northern region of Wisconsin, wetlands are abundant and diverse. This area is known for its numerous bog and fen wetlands, which are particularly prevalent in regions with glacial outwash or where groundwater sources are found near the surface. These wetlands support a range of unique and specialized plant species, such as pitcher plants, sundews, and cranberries. They also provide essential breeding grounds for a variety of bird species, including waterfowl and songbirds.

Central Region Wetlands

The central region of Wisconsin is characterized by a mix of wetland types, including marshes, swamps, and intermittent wetlands. These wetlands are often influenced by both groundwater and surface water sources. Central region wetlands are valuable for their water purification capabilities, supporting a variety of waterfowl and shorebird species. They also provide recreational opportunities for fishing, boating, and nature observation.

Southern Region Wetlands

In the southern region of Wisconsin, wetlands are more scarce due to extensive agricultural and urban development. However, there are still important wetlands in this area, including marshes and floodplain wetlands along major rivers such as the Wisconsin River and the Mississippi River. These wetlands provide important habitat for migratory birds, waterfowl, and other wildlife species. Additionally, efforts are underway to restore and create wetlands in urban and suburban areas to improve water quality and enhance wildlife habitat.

Notable Wetland Areas

Lake Poygan Wildlife Area

Lake Poygan Wildlife Area is one of the largest wetland complexes in Wisconsin, encompassing over 14,000 acres of diverse habitats. The area consists of marshes, forested wetlands, and upland prairies, providing critical habitat for waterfowl, shorebirds, and a variety of plant and animal species. Visitors to Lake Poygan Wildlife Area can enjoy wildlife viewing, hunting, fishing, and hiking opportunities.

Horicon Marsh State Wildlife Area

Horicon Marsh State Wildlife Area is a globally significant wetland complex and is considered one of the largest freshwater marshes in the United States. This expansive wetland spans over 32,000 acres and provides vital habitat for a diverse array of wildlife, including nesting and migrating birds, fish, and mammals.

Wetland Research and Education

Academic Institutions

Several academic institutions in Wisconsin conduct research and provide educational opportunities related to wetlands. Universities such as the University of Wisconsin-Madison, the University of Wisconsin-Milwaukee, and the University of Wisconsin-Stevens Point offer courses and research programs focusing on wetland ecology, hydrology, and restoration. These institutions contribute to the knowledge and understanding of wetland ecosystems and their importance in Wisconsin.

Wetland Research Centers

Wisconsin is home to several wetland research centers that are dedicated to studying and conserving wetland ecosystems. The Wisconsin Wetland Inventory, managed by the Wisconsin Department of Natural Resources, provides comprehensive wetland data and mapping to support wetland management and research. The Nelson Institute Center for Limnology and the River Studies Center at the University of Wisconsin-La Crosse conduct research on wetland hydrology, water quality, and ecosystem dynamics.

Educational Programs

Various organizations in Wisconsin offer educational programs focused on wetland conservation and environmental literacy. The Aldo Leopold Foundation, the Riveredge Nature Center, and the Mead Wildlife Area all offer educational workshops, field trips, and hands-on activities for students and the general public. These programs aim to raise awareness about the value of wetlands and inspire stewardship of these important ecosystems.

Wetland Restoration Projects

One notable wetland restoration project in Wisconsin is the Hunters Lake Project in Polk County. This project involved restoring a drained and degraded wetland complex to its original hydrological and ecological state. Dams were removed to allow for the reestablishment of natural water flow, and native vegetation was replanted to enhance habitat for wildlife. The project has resulted in improved water quality, increased biodiversity, and increased recreational opportunities for visitors.

Another notable wetland restoration project is the Kickapoo River Wetland Restoration Project in Vernon County. This project involved restoring and enhancing wetlands along the Kickapoo River, which had experienced extensive agricultural drainage and degradation. The project included the construction of berms and water control structures to restore natural hydrological patterns and the planting of native wetland vegetation. The restoration efforts have improved water quality, reduced erosion, and created valuable wildlife habitat.

The Horicon Marsh Enhancement Project is a ongoing wetland restoration project in Dodge County. The project focuses on managing water levels and invasive species, restoring native wetland vegetation, and improving habitat for waterfowl and other wildlife. The restoration efforts aim to enhance the overall ecological integrity of the marsh and promote public enjoyment through improved recreational opportunities.
