The St. Croix Wetland Management District in west-central Wisconsin, United States, encompasses a diversity of habitats lying along the eastern edge of the tallgrass prairie. Within the eight-county district, one can travel north through the high river bluffs of Pepin County, to the prairie potholes of St. Croix County, and then to the pine barrens of Burnett County.
The district includes Barron, Burnett, Dunn, Washburn, Pierce, Pepin, Polk and St. Croix counties. The central portion of St. Croix County, the heart of the district, is known as the Star Prairie Pothole Grasslands. These grasslands are ranked sixth out of 26 priority grassland landscapes in Wisconsin.
The district manages relatively small tracts of prairie wetland and grassland habitats known as waterfowl production areas (WPAs). WPAs are purchased using Federal Duck Stamp dollars within the historic prairie pothole portion of the district, including southern Polk, St. Croix and Dunn counties. After purchase, prairie wetland and grassland habitats are restored and then managed for breeding waterfowl, other migratory birds and indigenous wildlife.
The district's 41 WPAs totaling 7,500 acres (30 km2) are administered by the U.S. Fish and Wildlife Service's National Wildlife Refuge System. In addition to managing WPAs, district staff provide assistance to private landowners who wish to manage their land to benefit wildlife.
The St. Croix Wetland Management District is adjacent to the Minneapolis/St. Paul Metropolitan Area of two million people. This presents unique opportunities and challenges for prairie wetland habitat preservation, restoration and management.
The Rainwater Basin wetland region is a 4,200 sq mi (11,000 km2) loess plain located south of the Platte River in south-central Nebraska. It lies principally in Adams, Butler, Clay, Fillmore, Hamilton, Kearney, Phelps, Polk, Saline, Seward, and York counties and extends into adjacent areas of southeastern Hall, northern Franklin, northern Nuckolls, western Saline, northern Thayer and northwestern Webster counties. Before European settlement, this plain was covered by prairie grasslands interspersed with thousands of ephemeral playa wetlands, called Rainwater Basins. Informally and locally, individual Nebraska Rainwater Basins are referred to as rainbasins, basins, lagoons, lakes, ponds, marshes, hay marshes, and lakes marshes. To the west, a tallgrass prairie in the east once gradually transitioned into mixed grass prairie. Currently, the Rainwater Basin wetland region is covered by farms, mainly growing corn and soybeans. Several, interspersed, stream courses, of which largest is the Big Blue River and its tributaries, drain this region. Riparian woodlands and upland slopes possessing oak woodlands are associated with these streams. In the spring and fall months, millions of migratory birds pass through the region to feed and rest. Along with riparian habitats associated Platte River, Big Blue River, its tributaries, and smaller streams, Rainwater Basins are a major component of the Central Flyway of North America.
Chase Lake Wetland Management District is located in the U.S. state of North Dakota. The district is located in what is known as the prairie–potholes region of lakes and ponds, which were left behind by the retreat of glaciers at the end of the last ice age. Hundreds of waterfowl production areas, Wildlife Development Areas, wetland easements, grassland easements and the easement refuge known as Halfway Lake National Wildlife Refuge, are managed by the district. The district is a part of the Arrowwood National Wildlife Refuge Complex.
The Chase Lake Prairie Project is an effort to restore and protect the largest remaining region in the lower 48 states for waterfowl production. Located in U.S. state of North Dakota and consisting of 5,500,000 acres (22,000 km2) spread across 11 counties, this region is composed of thousands of lakes and ponds and grassland prairie. 97% of the land area is privately owned, with the U.S. Fish and Wildlife Service working with landowners to protect wetlands and associated prairie regions in a collaborative effort to ensure the region continues to provide habitat for the millions of birds and other wildlife that are dependent on the ecosystem.
The Valley City Wetland Management District is located in the U.S. state of North Dakota and consists of 76,000 acres (307 km2). The wetland district is a substation of the Arrowwood National Wildlife Refuge Complex, overseen by the U.S. Fish and Wildlife Service. 82 waterfowl production areas and four separate national wildlife refuges which are privately owned are in turn managed by the wetland district as easement refuges. The wetland district is in portions of 5 counties in the Prairie Pothole Region that was created by the retreat of glaciers 12,000 years ago, during the last glacial maximum. One third of the protected lands are wetlands with the balance consisting of prairie.
The Prairie Pothole Region is an expansive area of the northern Great Plains that contains thousands of shallow wetlands known as potholes. These potholes are the result of glacier activity in the Wisconsin glaciation, which ended about 10,000 years ago. The decaying ice sheet left behind depressions formed by the uneven deposition of till in ground moraines. These depressions are called potholes, glacial potholes, kettles, or kettle lakes. They fill with water in the spring, creating wetlands, which range in duration from temporary to semi-permanent. The region covers an area of about 800,000 sq. km and expands across three Canadian provinces and five U.S. states. The hydrology of the wetlands is variable, which results in long term productivity and biodiversity. The PPR is a prime spot during breeding and nesting season for millions of migrating waterfowl.
Audubon Wetland Management District is located in the U.S. state of North Dakota and consists of 123 Waterfowl Production Areas (WPAs), 8 National Wildlife Refuges (NWRs), and numerous wetland and grassland easements and over 100 separate wetland areas set aside to preserve habitat for bird, plant and mammal species. These lands contain valuable wetland and grassland habitat for waterfowl and other migratory birds, and many other species of wildlife. Scattered throughout west central and southwestern North Dakota in McLean, Ward, and Sheridan Counties, the district is managed by the U.S. Fish and Wildlife Service and from Audubon National Wildlife Refuge. Hundreds of lakes and marshlands in this region provide critical habitat for migratory and nesting bird species.
The Michigan Wetland Management District consists of a 14-county area and includes three waterfowl production areas (WPAs): the 160-acre (0.65 km2) Schlee WPA and the 138-acre (0.56 km2) Mahan WPA in Jackson County and the 77-acre (310,000 m2) Kinney WPA in Van Buren County. The Michigan Department of Natural Resources, Wildlife Division, oversees day-to-day management of these three areas through a partnership with the U.S. Fish and Wildlife Service.

Litchfield Wetland Management District is located on the eastern edge of the Prairie Pothole Region in central Minnesota. More than 33,000 acres (130 km2) of United States Fish and Wildlife Service-owned land and 8,000 acres (32 km2) of wetland easements provide marsh, prairie, transition, and woodland habitats. District lands are located on over 150 waterfowl production areas scattered throughout seven counties. These areas vary greatly in size and vegetation and provide habitat for numerous plant and animal species.
The Minnesota Valley Wetland Management District is a fourteen-county district located in east central Minnesota, United States. It includes portions of the Minnesota, Cannon, and Mississippi River watersheds. The United States Fish and Wildlife Service works to protect the area's natural landscape through private lands habitat restorations, acquisition of waterfowl production areas (WPAs), and management of FmHA conservation easements. Since 1990, the Service has acquired 4,255 acres (17.22 km2) of WPAs and approximately 1,898 easement acres (7.68 km2). Private land restoration projects total 7,011 acres (28.37 km2) of wetland in 1,227 basins and 4,849 acres (19.62 km2) of native prairie on 223 sites.
The Morris Wetland Management District includes 244 waterfowl production areas, encompassing over 50,000 acres (200 km2) scattered throughout an eight-county area. Like other wetland management districts in the prairie states, the goal of the Morris District is to restore and protect sufficient wetland and grassland habitat to meet the needs of prairie wildlife, particularly breeding waterfowl, as well as provide places for public recreation.
The Windom Wetland Management District acquires and manages Waterfowl Production Areas, enforces wetland easements, and provides conservation assistance to landowners in 12 southwestern Minnesota counties. The landscape is dominated by intense, row-crop agriculture, which has led to the drainage of most wetlands and widespread water quality problems. Deteriorating drainage tile systems and the abundance of historic wetland basins provide unlimited opportunities for wetland restorations.
Devils Lake Wetland Management District is located in the heart of the Prairie Pothole Region of the United States. The District was established in 1962 to purchase and protect wetland habitat for migratory waterfowl and other wildlife in northeastern North Dakota. One of the primary objectives of Devils Lake Wetland Management District is to provide wetland and grassland habitat for waterfowl in the spring and summer for nesting and feeding. The other primary objective is to provide migration habitat for waterfowl in the spring and fall.
Located in south-central North Dakota, Kulm Wetland Management District was established in 1971. Located in the Prairie Pothole Region of North America, Kulm Wetland Management District provides breeding, nesting, and brood rearing areas for many species of waterfowl and other migratory birds. The District currently manages 201 waterfowl production areas that total 45,683 acres (184.87 km2), 3 national wildlife refuges that are easement refuges, and 120,000 acres (490 km2) of wetland and grassland easements. The District's headquarters is in Kulm, North Dakota.
Long Lake Wetland Management District encompasses three counties in south-central North Dakota, an area famed for its wealth of waterfowl-producing potholes and native prairie grasslands. Headquarters for the Wetland Management District is located in the Long Lake National Wildlife Refuge office near Moffit, North Dakota, which is about 35 miles southeast of Bismarck. Topographical landforms of the area include Missouri Coteau and Missouri River Slope. Precipitation averages just under 16 inches per year. Approximately 68 percent of the land in the three county area remains virgin sod - native mixed-grass prairie. The dominant land use is cattle grazing. The Coteau wetlands found in the northeastern portion of the Wetland Management District are classic prairie potholes of various sizes and types that are prime duck production habitat. These areas, when wet, are very productive. Soils in this area are generally deep and quite productive. Due to the rolling nature of the landscape on the Coteau, a lot of the land is also characterized as highly erodible. Conversely, many of the wetlands on Missouri River Slope portion of the Wetland Management District are large semi-permanent and permanent alkali wetlands. There are 21 wetland sites on the Missouri River Slope that have a history of periodic avian botulism outbreaks. These areas occasionally present localized problems for significant numbers of migratory birds. Soils on the Missouri River Slope are characteristically shallow with high proportions of sand and gravel. Much of the land is highly erodible. Since 1985, substantial land acreage in the three county area that was once farmed has been retired to Conservation Reserve Program grasslands. The program has assisted in restoring waterfowl populations for many species in the Wetland Management District which exceed the highest level ever recorded since surveys began.
The Leopold Wetland Management District is named after Aldo Leopold, who is widely acknowledged as the father of wildlife conservation in America. Leopold is perhaps best known as the author of A Sand County Almanac, a book compiled of essays written on his farm in central Wisconsin. In tribute to his philosophy, the Leopold Wetland Management District is dedicated to preserving, restoring, and enhancing wildlife habitat in Wisconsin for the benefit of present and future generations.
