Impacts of Wetland Characteristics on Duck Use in the Prairie Pothole Region (PPR) 1987-2013
… Survey, has been conducted annually in the U.S. Prairie Pothole Region. The survey was designed to assess the influence of the Small Wetlands Acquisition Program on contributions to continental waterfowl populations (Cowardin et al. 1995). Each year cooperators visit sample wetlands during two …

Changes in Wetland Conditions and Wetland Plant Communities in the Prairie Pothole Region After 50 Years
… plant communities within wetland zones in the Prairie Pothole Region. In 1961-1966, Robert E. Stewart and Harold A. Kantrud conducted a study to investigate the relationship of wetland plant communities to variations of water permanence and chemistry on three study areas: Crystal Springs, …

Effects of land-use practice on wetland soil hydrology, salinity, and biogeochemistry in the prairie pothole region
… and pasture (PA) in two (site A and B) semi-arid prairie pothole region (PPR) wetland systems. In a microcosm experiment, GHG (CO2, CH4, and N2O) emissions and EEAs [β-glucosidase (BG), N-acetyl glucosaminidase (NAG), and alkaline phosphatase (AP)] were measured in intact soil cores (30-cm depth) …

A Landscape Approach to Grassland Bird Conservation in the Prairie Pothole Region of the Northern Great Plains
Prairie is one of the most imperiled ecosystems, and grassland birds have experienced steeper and more consistent declines than any other group of birds in North America. Habitat-based planning tools are a cornerstone of conservation in forested ecosystems, but remain a novel approach in …

A Physiological Assessment of Wetland Habitats for Spring-migrating Ducks in the Agricultural Landscapes of the Southern Prairie Pothole Region
… of grassland and wetland ecosystems in the Prairie Pothole Region (PPR) has been a pervasive challenge for conservationists dating back to the early 1900s. The legacy of ever-increasing agricultural intensity in the southern portions of the PPR, including eastern South Dakota, has left many …

Delineation of Surface Water Features Using RADARSAT-2 Imagery and a TOPAZ Masking Approach over the Prairie Pothole Region in Canada
The Prairie Pothole Region (PPR) is one of the most rapidly changing environments in the world. In the PPR of North America, topographic depressions are common, and they are an essential water storage element in the regional hydrological system. The accurate delineation of surface water bodies is …

Investigating Grassland and Cropland Conversion Decisions in the Dakotas, 2015 Producers Survey and Analysis
… by 1,026 producers located in 57 counties of the Prairie Pothole Region (PPR) were used to evaluate land conversions. This thesis attempts to identify the land use conversion incidence and rate (grass to crop and crop to grass); the link between past and projected land use conversion decisions in …
