Climate-driven state shifts in the Prairie Pothole Region: assessing future impacts relevant to the management of wetland habitats critical to waterfowl

The Prairie Pothole Region (PPR) covers parts of five states and three Canadian provinces. The region contains millions of wetlands that annually produce 50-80% of the continent’s duck population. Previous modeling efforts indicated that climate change would result in a shift of waterfowl habitat from the central PPR to the southeast PPR where the majority of wetlands have been drained....

Temporal and spatial patterning of aquatic macroinvertebrate communities in response to changing environmental conditions

An increased understanding of prairie-pothole-wetland macroinvertebrate dynamics is crucial to better inform conservation strategies related to waterfowl production, biodiversity enhancement, and wetland function/health maintenance. Wetlands in general are highly variable in space and time, and wetland macroinvertebrates are adapted to this great variability. Wetland ecosystems are also...

Estimating offsets for avian displacement effects of anthropogenic impacts

The avian-impact offset method (AIOM) quantifies the amount of habitat needed to provide equivalent biological value for birds displaced by energy and transportation infrastructure. The AIOM can be applied in situations where avian displacement (i.e., behavioral avoidance) requires compensatory mitigation. The AIOM is based on the ability to define five metrics: impact distance, impact area,...

A systems approach to modeling effects of climate and land-use change on prairie wetland ecosystems

This effort is focused on developing an process-based, systems model for prairie-pothole wetlands to facilitate forecasts of how climate and land-use change will influence wetland processes and biota. The Pothole Hydrology Linked System Simulator model (PHyLiSS) simulates changes in hydrology, water chemistry, plant communities, invertebrates and other biota as a result of altered temperature...

Understanding consequences of management strategies for farmed wetlands to ecosystem services in the Prairie Pothole Region

NPWRC is leading a partnership with North Dakota State University to examine ecological, social, and financial considerations of farming practices within temporarily-ponded wetlands. There has been a long history of cropping prairie pothole wetlands which are embedded within farm fields. Often wet conditions during spring or summer prevent farmers from getting a harvestable yield from these...

Restoration of wetland invertebrates to improve wildlife habitat in Minnesota

Northern Prairie Wildlife Research Center (NPWRC) is investigating limitations to restoring abundant aquatic macroinvertebrate populations to Minnesota wetlands and shallow lakes. Recent research on larger more permanent wetlands in Minnesota indicates that there have been decreases in quality of wetlands of use by ducks. That research also describes a decline in abundance of amphipods, a...

Importance of wetlands in intensively farmed landscapes to duck production

The Prairie Pothole Region of the northern Great Plains annually hosts 50–80% of North America’s ducks during the breeding season. Accordingly, there are significant government and private funds that go to conservation for the purposes of improving duck production in the region. The Prairie Pothole Region ecosystem has a number of stressors, intensive agriculture being chief among them. The...

Interactions of consolidation drainage and climate on water-level dynamics, wetland productivity, and waterbirds

Northern Prairie Wildlife Research Center (NPWRC) recently completed a project aimed at understanding the impacts of wetland drainage on wetlands that receive drainage water. The biological communities of prairie pothole wetlands evolved in a hydrologically dynamic system due to periodic wet and dry conditions.  NPWRC research indicates that relative to wetlands in undrained landscapes,...

Impacts of wind-turbine energy complexes on northern prairie grouse

Wind-energy development in the northern Great Plains primarily occurs along the Missouri Coteau and Missouri River Plateau in North Dakota and South Dakota.  While these areas rank high in wind-energy potential they also contain important breeding habitat for sharp-tailed grouse and greater prairie-chickens.  The impact of these wind-energy developments on prairie grouse populations and trends...

Interaction of land use and wet/dry cycles on invertebrate populations of northern prairie wetlands: implications for waterbird habitat conservation

This effort is aimed at understanding how productivity of larger and more permanent wetlands is influenced by a combination of inter-annual hydrological dynamics and land-use impacts. Historically, aquatic-invertebrates productivity and abundance was driven by inter-annual hydrological dynamics because drying periods allow for nutrient cycling and a subsequent pulse of productivity when wet...

USDA Conservation Reserve Program (CRP) durability assessment with FORT

Northern Prairie Wildlife Research Center is assisting the Fort Collins Science Center (FORT) in conducting an assessment of the current status of agricultural lands that were previously, but not currently, enrolled in the U.S. Department of Agriculture’s Conservation Reserve Program (CRP). The goal of...

Potential effects of energy development on environmental resources of the Williston Basin in Montana, North Dakota, and South Dakota

Federal resource managers in the Williston Basin need to understand how the recent expansion of oil and gas development is affecting a range of natural resources. The Bakken Federal Executive Group (BFEG), a group of representatives from over a dozen federal and tribal agencies, called for a report that synthesizes existing information about the potential impacts from energy development. The...
