The Prairie Pothole Region is recognized as one of the most productive areas for waterfowl in North America and supports an estimated 50–80 % of the continent’s duck population. This important habitat is threatened by climate change and continued land-use change. The goal of this research is to establish a framework for assessing future impacts of climate and land-use change on Prairie Pothole we

The Prairie Pothole Region is recognized as one of the most critical breeding habitats for waterfowl in North America and is used by an estimated 50–80 % of the continent’s breeding duck population. The ongoing acquisition program of the U.S. Fish and Wildlife Service National Wildlife Refuge System has conserved approximately 1.3 million hectares of critical breeding-waterfowl habitat. This curre

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...

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...

The Prairie Pothole Region (PPR) of North America is one of the most important breeding areas for continental waterfowl populations, a Department of Interior (DOI) trust resource. Land use and climate both influence the functioning of the region’s wetland ecosystems, with effects not just on the waterfowl that depend on these wetlands, but also on the services they provide to society, such as...

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...

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...

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...

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...

The North American Prairie Pothole Region (PPR) is an expansive region that covers parts of five Midwestern states and three Canadian provinces. This region contains millions of wetlands in which waterfowl breed and from which 50-80% of the continent's migratory ducks originate each year. Previous modeling efforts indicated that climate change would result in a shift of suitable waterfowl breedin

Geographically Isolated Wetlands (GIWs) occur along gradients of hydrologic and ecological connectivity and isolation, even within wetland types (e.g., forested, emergent marshes) and functional classes (e.g., ephemeral systems, permanent systems, etc.). Within a given watershed, the relative positions of wetlands and open-waters along these gradients influence the type and magnitude of their che
