Introduced rats are notorious predators of birds and their nests worldwide, but especially on remote islands. Rats ( Rattus exulans ) first arrived in Hawai‘i with Polynesian colonists about 1,000 years ago, resulting in deleterious consequences for native birds and ecosystems. Since Western contact in 1778, two additional rat species have become established in Hawai‘i, including the highly...

When the wolf was listed as endangered, the last remaining mainland wolf population in the lower 48 states was in the Superior National Forest (SNF) of northeastern Minnesota. Since then, using radiocollaring and aerial tracking, we have studied the wolf population trend, factors influencing it, and prey species, white-tailed deer, moose, and beavers, affected by wolves. During winter 2018-2019...

Pollinator declines have emphasized the need for a greater understanding of plant-pollinator networks and land management activities that improve pollinator habitat. At the request of USDA and FWS partners, Northern Prairie Wildlife Research Center created the Pollinator Library for managers and researchers interested in improving pollinator forage on federal and private lands. The aim of the...

If invasive plants are producing pollen and nectar used by native pollinators, what happens when a manager decides to control the invasive plant? Northern Prairie Wildlife Research Center is addressing this question and has found that pollinators are adept at changing their resource acquisition strategies as abundantly flowering invasive species decline. In addition, it appears that the invasive...

Federal cropland retirement programs are increasingly being used to provide resources for pollinators (e.g., nectar, pollen, host plants). Pollinator-friendly plant species (e.g., alfalfa, sweetclover) were readily included in seed mixes in Conservation Reserve Program (CRP) grasslands since its inception in the 1985 Farm Bill. Through time, some native plant species (e.g., milkweeds) also...

Since its inception in 1933, the U.S. Farm Bill has been one of the most influential federal policies for agriculture and food production. Provisions within the Farm Bill have profound influence on global trade, nutrition programs, commodity crop programs, rural communities, and land conservation. Northern Prairie’s research quantifies the impact on pollinator forage and health of USDA...

The only self-sustaining population of endangered whooping cranes nests within and near Wood Buffalo National Park, Canada, migrates through the Great Plains, and winters primarily along the Texas Gulf Coast. Our objectives of this collaborative project are to address the entire annual life cycle of this species by advancing knowledge of breeding, wintering, and migration ecology, including...

Least terns and piping plovers are the subject of numerous population monitoring efforts. Population monitoring requires periodic visits to nesting areas to count and assess breeding status of the birds. At higher visit frequencies, detection of nests and chicks improves as does ability to determine outcomes of nesting attempts, resulting in more complete and accurate productivity information. But...

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...
