Brine Contamination to Plains and Potholes Environments from Energy Development in the Williston Basin
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...Tangen, Brian A.; Finocchiaro, Raymond G.; Gleason, Robert A.
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...Gleason, Robert A.; Tangen, Brian A.; Gleason, Robert A.; Contributions by Chesley-Preston, Tara L.; Coleman, James L.; Haines, Seth S.; Jenni, Karen E.; Nieman, Timothy L.; Peterman, Zell E.; van der Burg, Max Post; Preston, Todd M.; Smith, Bruce D.; Tangen, Brian A.; Thamke, Joanna N.
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...Finocchiaro, Raymond G.; Tangen, Brian A.; Gleason, Robert A.
Assessment of sediments in the riverine impoundments of national wildlife refuges in the Souris River Basin, North Dakota
Accelerated sedimentation of reservoirs and riverine impoundments is a major concern throughout the United States. Sediments not only fill impoundments and reduce their effective life span, but they can reduce water quality by increasing turbidity and introducing harmful chemical constituents such as heavy metals, toxic elements, and nutrients. U....Tangen, Brian A.; Laubhan, Murray K.; Gleason, Robert A.
Assessment of water-quality data from Long Lake National Wildlife Refuge, North Dakota--2008 through 2012
ong Lake National Wildlife Refuge, located in south-central North Dakota, is an important habitat for numerous migratory birds and waterfowl, including several threatened or endangered species. The refuge is distinguished by Long Lake, which is approximately 65 square kilometers and consists of four primary water management units. Water levels in...Tangen, Brian A.; Finocchiaro, Raymond G.; Gleason, Robert A.; Rabenberg, Michael J.; Dahl, Charles F.; Ell, Mike J.
A model for evaluating effects of climate, water availability, and water management on wetland impoundments--a case study on Bowdoin, Long Lake, and Sand Lake National Wildlife Refuges
Many wetland impoundments managed by the U.S. Fish and Wildlife Service (USFWS) National Wildlife Refuge System throughout the northern Great Plains rely on rivers as a primary water source. A large number of these impoundments currently are being stressed from changes in water supplies and quality, and these problems are forecast to worsen...Tangen, Brian A.; Gleason, Robert A.; Stamm, John F.
A multi-refuge study to evaluate the effectiveness of growing-season and dormant-season burns to control cattail
Proliferation of invasive cattails (for example, Typha x glauca, T. angustifolia) is a concern of wetland managers across the country, and numerous methods have been used to control the spatial extent and density of the plant. To date, however, no single method has proven widely or consistently effective at reducing the long-term growth and spread...Gleason, Robert A.; Tangen, Brian A.; Laubhan, Murray K.; Lor, Socheata
Valuing ecosystem and economic services across land-use scenarios in the Prairie Pothole Regions of the Dakotas, USA
This study uses biophysical values derived for the Prairie Pothole Region (PPR) of North and South Dakota, in conjunction with value transfer methods, to assess environmental and economic tradeoffs under different policy-relevant land-use scenarios over a 20-year period. The ecosystem service valuation is carried out by comparing the biophysical...Gascoigne, William R.; Hoag, Dana; Koontz, Lynne; Tangen, Brian A.; Shaffer, Terry L.; Gleason, Robert A.
USDA conservation program and practice effects on wetland ecosystem services in the Prairie Pothole Region
Implementation of the U.S. Department of Agriculture (USDA) Conservation Reserve Program (CRP) and Wetlands Reserve Program (WRP) has resulted in the restoration of >2 million ha of wetland and grassland habitats in the Prairie Pothole Region (PPR). Restoration of habitats through these programs provides diverse ecosystem services to society,...Gleason, Robert A.; Euliss, Ned; Tangen, Brian A.; Laubhan, M. K.; Browne, B.A.
Examination of brine contamination risk to aquatic resources from petroleum development in the Williston Basin
U.S. Geological Survey scientists and cooperating partners are examining the potential risk to aquatic resources (for example, wetlands, streams) by contamination from saline waters (brine) produced by petroleum development in the Williston Basin of Montana, North Dakota, and South Dakota. The primary goals of this study are to provide a science-...Gleason, Robert A.; Thamke, Joanna N.; Smith, Bruce D.; Tangen, Brian A.; Chesley-Preston, Tara; Preston, Todd M.
Literature Review and Database of Relations Between Salinity and Aquatic Biota: Applications to Bowdoin National Wildlife Refuge, Montana
Long-term accumulation of salts in wetlands at Bowdoin National Wildlife Refuge (NWR), Mont., has raised concern among wetland managers that increasing salinity may threaten plant and invertebrate communities that provide important habitat and food resources for migratory waterfowl. Currently, the U.S. Fish and Wildlife Service (USFWS) is...Gleason, Robert A.; Tangen, Brian A.; Laubhan, Murray K.; Finocchiaro, Raymond G.; Stamm, John F.
Ecosystem Services Derived from Wetland Conservation Practices in the United States Prairie Pothole Region with an Emphasis on the U.S. Department of Agriculture Conservation Reserve and Wetlands Reserve Programs
Implementation of the U.S. Department of Agriculture (USDA) Conservation Reserve Program (CRP) and Wetlands Reserve Program (WRP) has resulted in the restoration of approximately 2,200,000 ha (5,436,200 acres) of wetland and grassland habitats in the Prairie Pothole Region. These restored habitats are known to provide various ecosystem services;...Gleason, Robert A.; Laubhan, Murray K.; Euliss, Ned H.
