Fish and Wildlife seasonal and temporary wetland assessment

The Prairie Pothole Region supports some of the most productive wetlands in the world for waterfowl. Up to 90% of seasonal and temporary wetlands have been lost in areas of the PPR due to the conversion of grasslands to croplands and the drainage of wetlands. Department of the Interior Waterfowl Production Areas (WPA) and National Wildlife Refuges (NWR) in North Dakota, South Dakota, and...

Improving wildlife habitat through management and restoration of native prairies on lands under Fish and Wildlife Service ownership

The extent of native prairie throughout the north-central United States has sharply declined since European settlement, and much that remains has been invaded by introduced cool-season grasses, reducing floristic diversity and quality. On lands under its ownership, the U.S. Fish and Wildlife Service is working to restore native prairie integrity by reducing occurrence of introduced species...

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...

Inventory, mapping, estimation, and monitoring of least tern and piping plover habitats on the upper Missouri River using satellite imagery

Emergent sandbar maps of the Missouri River produced by Northern Prairie Wildlife Research Center continue to be used by the U.S. Army Corps of Engineers and U.S. Fish and Wildlife Service to monitor and manage critical breeding habitat for the endangered Interior population of least terns and the threatened Northern Great Plains population of piping plovers.  These maps have been created and...

Long-term changes in wetland and prairie landscapes

Over the past 50 years, wetlands in the Prairie Pothole Region of the northern Great Plains have experienced a wide range of climatic conditions (severe drought to extreme wet), expansion of invasive species such as hybrid cattail, and disturbances (e.g., grazing, burning, flooding, drainage).  In this study, we revisited wetlands that Stewart and Kantrud (1971) studied 50 years ago to...

Alpine Wildlife and Snowpack Dynamics in the North Cascades

Mountain ecosystems are expected to change with continued reductions in annual snowpack that have been observed worldwide over the past half-century. Recent snow droughts in North America have been attributed to unusually warm temperatures that cause winter precipitation to fall as rain, rather than snow. Many species of alpine wildlife depend on snowpack for insulation from extreme cold and...

National Phenology Network (NPN)

The USA National Phenology Network is a national-scale science and monitoring initiative focused on phenology, which is the study of seasonal life-cycle events such as leafing, flowering, reproduction and migration, as a tool to understand how plants, animals and landscapes respond to environmental variation and change.

Monitoring Avian Productivity and Survivorship (MAPS)

Dr. Barbara Kus is a partner in an international bird-monitoring program to provide long-term data throughout North America. MAPS or “Monitoring Avian Productivity and Survivorship”, uses capture and banding data to compile basic demographic parameters of migratory species, many of which are imperiled regionally and even globally. Age- and sex-specific data on annual survival, reproduction,...

Bat Research in California

The primary goal of this bat research program is to develop projects that increase our understanding of basic ecology and natural history of western bat species, while simultaneously providing needed data to inform conservation measures and management decisions in the West. Dr. Brian Halstead, together with Gabriel Reyes, studies the habitat and resource selection, movement ecology, demography...
