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...
Breeding ecology and demographics of least terns and piping plovers at the Central Platte River, Nebraska
The Platte River Recovery Implementation Program (PRRIP) partnered with Northern Prairie Wildlife Research Center (NPWRC) to study demographics of least terns and piping plovers at the Central Platte River in Nebraska. Due to water management and other alterations, riverine habitat for least terns and piping plovers has become degraded. Least terns and piping plovers, however, have begun breeding...
Development of survey methods for spring-migrating waterfowl in the Rainwater Basin
The Rainwater Basin Wetland Complex is a mid-latitude focal point of spring migration for numerous species of birds in the Great Plains. The Rainwater Basin Joint Venture (RWBJV) and partners desire geospatial models to identify characteristics of wetland complexes and understand local and landscape level factors that influence habitat selection of migrating waterfowl. To support this effort, we...
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 conservation...
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 North...
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 mallards to...
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 composition...
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 mid...
