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. However...
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 influenced...
Quantifying ecosystem services provided by depressional wetlands in the Upper Mississippi
Northern Prairie Wildlife Research Center has conducted multiple research efforts related to developing methodology for quantifying the environmental and societal services provided by prairie-pothole wetland ecosystems. In this effort, we are exploring the feasibility of applying methodologies similar to those developed wetland ecosystems within the Prairie Pothole Region to other landscapes where...
Quantify the multiple services performed by wetland ecosystems in the Prairie Pothole Region of the United States
This research effort is focused on incorporating land-use and land-cover change into forecasting models that accounted for variations in agricultural and conservation practices and programs. The primary tool being used is the Integrated Valuation of Ecosystem Services and Tradeoffs (InVEST) modeling suite. We have parameterized this modeling tool for the prairie-pothole region, and developed new...
Description of aquatic vegetation and invertebrate communities at Big Stone National Wildlife Refuge
Big Stone National Wildlife Refuge is situated within a riverine system where refuge wetlands receive sediment-laden inflows that have been associated with diminished plant communities and water quality conditions. Accordingly, improved habitat- and water-quality conditions have been recognized as overall management goals, and the collection of baseline biotic and abiotic data has been identified...
Assessment of pattern tile drainage on wetland hydrology and ecosystem services in the Prairie Pothole Region
Prairie Pothole Region wetlands provide numerous ecological services to society such as wildlife habitat, water storage, and carbon sequestration. Agricultural production in the region has been enhanced through the expanded installation and use of subsurface drainage systems, but these systems may have a negative impact on the region’s wetlands, including those protected by conservation easements...
Development and validation of wetland-connectivity indicators in the U.S. Prairie Pothole Region
We are working in partnership with the U.S. Environmental Protection Agency to (1) quantify cumulative effects of prairie-pothole wetlands on stream communities; (2) explore relationships between aquatic-system connectivity and genetic-, species-, and ecosystem-scale biological diversity at watershed and landscape scales; (3) develop mapping unit descriptors based on biotic community traits for...
Development, application, and refinement of a systems model for prairie wetlands
NPWRC is developing, applying, and refining an integrated, process-based, systems model for prairie-pothole wetlands to facilitate forecasts of how climate and land-use change will affect 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...
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 areas...
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...
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 shrimp...
Evaluating wetland ecosystem health using real-time nutrient dynamics of ducks
Northern Prairie Wildlife Research Center (NPWRC) leads a collaborative effort, spanning several studies, with the objective of improving techniques to assess the quality of spring migration habitat for ducks. Spring is a critical time in in the life cycle of migratory ducks because during migration they experience peak energetic needs at a time when food resources are often at their scarcest...
