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...

Northern Prairie Wildlife Research Center (NPWRC) is helping to improve the monitoring of federally listed least terns and piping plovers by the U.S. Army Corps of Engineers at John Martin Reservoir in Southeastern Colorado. NPWRC is providing information to the USACE aimed to improve their habitat management and productivity monitoring. NPWRC is also providing the capability to mark adults and...

NPWRC is leading a multi-agency study to understand metapopulation dynamics of piping plovers in the Northern Great Plains. Piping plovers are a federally listed species that nests on riverine sandbars and shorelines of wetlands and reservoirs. These habitats are dynamic in response to climate and water-management regimes of the Missouri River. The US Army Corps of Engineers manages the Missouri...

The largest recorded flood event on the Missouri River occurred during 2011. Northern Prairie Wildlife Research Center recently concluded a study that evaluated effects of that flood on least tern and piping plover breeding populations. These federally-listed species nest on riverine sandbars and reservoir shorelines. Since construction of the dams on the Missouri River there have been few floods...

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...

The North American Breeding Bird Survey (BBS) provides much essential information for assessing bird populations, but it is unknown how inherent assumptions of the BBS apply to grassland birds in the Northern Plains. Understanding the effects of these assumptions on our understanding of grassland bird populations is essential given widespread declines of grassland birds as well as recent and...

Midcontinent sandhill cranes occupy a large geographic area of central and western North America and northeastern Asia during breeding, winter, and migration. They are a species representing a unique convergence of multiple user groups with an interest in the continued health of this population. Tens of thousands of people view cranes during spring staging at the Platte River Valley in Nebraska...

Interest in the immune systems of wild birds has increased as public health authorities have recognized that many emerging infectious diseases of wildlife can be transmitted to humans (i.e., zoonoses). Eco-immunology is an emerging field that characterizes how immune adaptations of wild species vary as a result of evolution in different habitats and niches. Present understanding of the influence...

With support from the U.S. Prairie Pothole Joint Venture (PPJV), the U.S. Forest Service, and The Nature Conservancy, Northern Prairie is synthesizing literature on the effects of management practices on grassland bird species. The need for these syntheses was identified by the PPJV, a part of the North American Waterfowl Management Plan, in support of its objective to stabilize or increase...

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...

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, a...

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...
