Response of grassland birds to habitat characteristics, oil wells, and roads in managed grasslands in the Little Missouri National Grassland in North Dakota

The U.S. Forest Service defines sensitive species as species that need special management to maintain and improve their status on National Forests and Grasslands, and prevent a need for listing under the Endangered Species Act. The Sprague’s pipit and Baird’s sparrow are listed as sensitive species in the Northern Region of the U.S. Forest Service. These species require large patches of native...

Breeding bird use of grasslands enrolled in the Conservation Reserve Program in the northern Great Plains

Agriculture is the dominant land use on privately owned lands in the northern Great Plains of the United States.  Management decisions on agricultural lands are influenced by a variety of policies and programs established by the federal government in periodic Farm Bills.  In 1985, Congress passed the Food Security Act.  Title XII of the Act established the Conservation Reserve Program or CRP,...

Distribution and habitat use of waterbirds

Waterbird distribution and habitat use are influenced by human activities of agriculture and land-management practices, such as grazing or burning.  For many waterbird species, our knowledge of their ecology and factors influencing their abundance and importance of different habitats is very limited.  Such information can help direct more effective habitat restoration, management, and...

Developing techniques to census and monitor American white pelicans and other colonial waterbirds at Chase Lake National Wildlife Refuge in North Dakota

Monitoring colonial waterbirds is essential to detect and to provide insights about changes in waterbird distribution and abundance.  For colonial waterbirds, major population fluctuations often go undetected because surveys are not conducted regularly, inventory methods are inconsistent, or estimates have unknown reliability.  The waterbird colony at Chase Lake National Wildlife Refuge in...

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...

Demographic analysis of waterfowl populations

Northern Prairie Wildlife Research Center (NPWRC) has a long history of conducting broad-scale demographic analyses on available waterfowl. Our current efforts are collaborative with a variety of partners. Current studies include: 1) analysis of banding data for lesser scaup to inform the role of harvest on the continental population; 2) analysis of North American survey information of...

An evaluation of waterfowl breeding ecology in the context of their predator community in eastern South Dakota

Population growth in upland-nesting ducks is highly influenced by spatial and temporal variation in nest survival, and mammalian predators are the major cause of nest failure.  Beginning in spring 2018, a graduate student from South Dakota State University and co-advised by a NPWRC scientist will study predator communities and their movements in landscapes with varying grassland patch...

Support to Fish and Wildlife Service and Prairie Pothole Joint Venture for monitoring and management of migratory bird populations

Sound management of migratory bird breeding populations in the U.S. Prairie Pothole Region hinges on effective monitoring programs and comprehensive analyses of long-term survey data.  To this end, Northern Prairie provides support to the U.S. Fish and Wildlife Service in several important areas.  The Four-Square-Mile Breeding Duck and Habitat Survey was developed by Northern Prairie in the...
