Brine Contamination to Plains and Potholes Environments from Energy Development in the Williston Basin
Understanding the Links Between Climate, Ecosystem Processes, Wetland Management, and Bird Communities in the Prairie Pothole Region of the Northern Great Plains
In semi-arid regions, riparian and wetland ecosystems function as important migratory and breeding habitats and add significantly to local and regional biodiversity; however, these ecosystems are increasingly threatened by climate change and the potential synergistic effects of increasing demand for water and invasion by exotic species. As a continuation of our inaugural USGS National...

Large increases in methane emissions expected from North America’s largest wetland complex Large increases in methane emissions expected from North America’s largest wetland complex
Natural methane (CH4) emissions from aquatic ecosystems may rise because of human-induced climate warming, although the magnitude of increase is highly uncertain. Using an exceptionally large CH4 flux dataset (~19,000 chamber measurements) and remotely sensed information, we modeled plot- and landscape-scale wetland CH4 emissions from the Prairie Pothole Region (PPR), North America’s...

Land management strategies influence soil organic carbon stocks of prairie potholes of North America Land management strategies influence soil organic carbon stocks of prairie potholes of North America
Soil organic carbon (SOC) stocks of Prairie Pothole Region (PPR) wetlands in the central plains of Canada and the United States are highly variable due to natural variation in biota, soils, climate, hydrology, and topography. Land-use history (cropland, grassland) and land-management practices (drainage, restoration) also affect SOC stocks. We conducted a region-wide assessment of...

Greenhouse gas fluxes of a shallow lake in south-central North Dakota, USA Greenhouse gas fluxes of a shallow lake in south-central North Dakota, USA
Greenhouse gas (GHG) fluxes of aquatic ecosystems in the northern Great Plains of the U.S. represent a significant data gap. Consequently, a 3-year study was conducted in south-central North Dakota, USA, to provide an initial estimate of GHG fluxes from a large, shallow lake. Mean GHG fluxes were 0.02 g carbon dioxide (CO2) m−2 h−1, 0.0009 g methane (CH4) m−2 h−1, and 0.0005 mg nitrous...

Effects of land use on greenhouse gas fluxes and soil properties of wetland catchments in the Prairie Pothole Region of North America Effects of land use on greenhouse gas fluxes and soil properties of wetland catchments in the Prairie Pothole Region of North America
Wetland restoration has been suggested as policy goal with multiple environmental benefits including enhancement of atmospheric carbon sequestration. However, there are concerns that increased methane (CH4) emissions associated with restoration may outweigh potential benefits. A comprehensive, 4-year study of 119 wetland catchments was conducted in the Prairie Pothole Region of the north...

Brine contamination to aquatic resources from oil and gas development in the Williston Basin, United States Brine contamination to aquatic resources from oil and gas development in the Williston Basin, United States
The Williston Basin, which includes parts of Montana, North Dakota, and South Dakota in the United States and the provinces of Manitoba and Saskatchewan in Canada, has been a leading domestic oil and gas producing region for more than one-half a century. Currently, there are renewed efforts to develop oil and gas resources from deep geologic formations, spurred by advances in recovery...

Greenhouse gas fluxes of grazed and hayed wetland catchments in the U.S. Prairie Pothole Ecoregion Greenhouse gas fluxes of grazed and hayed wetland catchments in the U.S. Prairie Pothole Ecoregion
Wetland catchments are major ecosystems in the Prairie Pothole Region (PPR) and play an important role in greenhouse gases (GHG) flux. However, there is limited information regarding effects of land-use on GHG fluxes from these wetland systems. We examined the effects of grazing and haying, two common land-use practices in the region, on GHG fluxes from wetland catchments during 2007 and...
