Support the Development of a National Park Service Midwest Region bison stewardship strategy
Bison have played a key role in shaping the grasslands of the Great Plains for millennia. National Parks are a major last bastion for wild herds of the national mammal and symbol of the Department of the Interior. However, even as the National Park Service aims to maintain as natural as possible ecosystem conditions within its parks’ boundaries, managers regularly make decisions affecting their...
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...
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...
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...
Improving wildlife-habitat modeling and assessments with lidar
Lidar has proven itself as a valuable tool for providing high-resolution digital elevation models and for quantifying forest stand metrics utilized by the forest industry. Studies are only beginning to emerge relating lidar data directly to wildlife species occurrences and abundances. NPWRC has been assessing capabilities of lidar data in various ecosystems to include the mixed forests in Maine...
Monitoring and modeling wetland chloride concentrations in relationship to oil and gas development
Extraction of oil and gas via unconventional methods is becoming an important aspect of energy production worldwide. Studying the effects of this development in countries where these technologies are being widely used may provide managers in other oil producing parts of the world with some insight in terms of concerns associated with development. Rapid increases in energy development in North...
