Wetland Soil Carbon in a Watershed Context for the Prairie Pothole Region
Journal of Environmental Quality, 2016Wetland restoration in the Prairie Pothole Region (PPR) often involves soil removal to enhance water storage volume and/or remove seedbanks of invasive species. Consequences of soil removal could include loss of soil organic carbon (SOC), which is important to ecosystem functions such as water-holding capacity and nutrient retention needed for plant re-

Duck Populations as Indicators of Landscape Condition in the Prairie Pothole Region
Environmental Monitoring and Assessment, 2001The Prairie Pothole Region of the northern Great Plains is an important region for waterfowl production because of the abundance of shallow wetlands. The ecological significance of the region and impacts from intensive agriculture prompted the U.S. Environmental Protection Agency to select it as one of the first areas for developing and evaluating ...

Pesticides, Including Neonicotinoids, in Drained Wetlands of Iowa’s Prairie Pothole Region
Wetlands, 2016Approximately 95 % of nearly 4 million acres of wetlands located in Iowa’s portion of the Prairie Pothole Region (Des Moines Landform Region) are currently drained and farmed for row-crop agriculture. Many of these wetland basins are too wet to produce consistent crop yields and too dry to function as ecologically intact wetlands.

Spring Nutrient Levels in Drained Wetlands of IOWA’s Prairie Pothole Region
Wetlands, 2017Approximately 95% of nearly 4 million acres of wetlands located in Iowa’s portion of the Prairie Pothole Region (Des Moines Landform Region) are currently drained and farmed for row crop agriculture. Many of these wetland basins are too wet to produce consistent crop yields and too dry to function as normal wetlands.

Landowner Conservation Attitudes and Behaviors in the Prairie Pothole Region
2018Long-term and widespread wetlands conservation within agricultural working lands remains tenable. There exists a need to identify alternative options for incentivizing wetland maintenance on private property. The objective of this research is to facilitate development of viable options by developing an understanding of how landowners view conservation,

Groundwater Connectivity of Upland-Embedded Wetlands in the Prairie Pothole Region
Wetlands, 2017Groundwater connections from upland-embedded wetlands to downstream waterbodies remain poorly understood. In principle, water from upland-embedded wetlands situated high in a landscape should flow via groundwater to waterbodies situated lower in the landscape.

Indicators of Wetland Condition for the Prairie Pothole Region of the United States
Environmental Monitoring and Assessment, 2002We describe a study designed to evaluate the performance of wetland condition indicators of the Prairie Pothole Region (PPR) of the north central United States. Basin and landscape scale indicators were tested in 1992 and 1993 to determine their ability to discriminate between the influences of grassland dominated and cropland dominated landscapes in ...

Secretive Marsh Bird Densities and Habitat Associations in the Prairie Pothole Region
Wetlands, 2019After centuries of wetland modification, wetland-dependent wildlife are of high conservation concern. Particularly important are secretive marsh birds, a cryptic and understudied guild of wetland-dependent birds, many of which have experienced population declines concurrent with anthropogenic modification of wetlands.

Landowner valuation of a working wetlands program in the Prairie Pothole Region
Agricultural Economics, 2019AbstractWetlands conservation within agricultural working lands is currently incentivized by land retirement programs and farm program eligibility criteria. Private ownership of the majority of agricultural lands within which these wetlands reside and growing opportunity costs facing landowners put wetlands at risk and motivate consideration of ...

Waterbird use of dynamic sheetwater wetlands in Iowa's Prairie Pothole Region
2018Substantial landscape alteration has occurred from the westward expansion of European settlement starting in the 18 th Century in the form of conversion of large expanses of land to agricultural production. This agricultural expansion was facilitated by the development and installation of artificial subsurface drainage to convert previously saturated ...
