Pollinators

Scientists from six USGS science centers are collaborating with USDA, university, and Tribal partners, and Department of the Interior land managers, to assess the status of pollinator communities and the distribution of species of conservation concern using environmental DNA. These methods will be used to improve assessments of habitat quality and pollinator responses to restoration, including...

Bombus aff inis, the rusty patched bumble bee, was federally listed as an endangered species in 2017 and has been identified as one of the top priority species for recovery nationally. Shortly after listing the species, the U.S. Fish and Wildlife Services and other partners prioritized the research needed to prevent the extinction of B. affinis . Some of the top research needs that were identified...

With scarcely 2% of native tallgrass prairie remaining today, it is imperative that we wisely manage what little remains to conserve prairie-dependent plants, pollinators, other animals and ecosystem processes. Two commonly used methods of prairie management are prescribed fire and conservation grazing. Either method may present trade-offs with respect to conservation of vulnerable plant, bee or...

Rising commodity crop prices, increased federal subsidies for biofuels, such as corn-based ethanol and soy-based biodiesel, and reduction in U.S. Farm Bill conservation programs have facilitated rapid land-use changes in the Northern Great Plains (NGP). Although renewable biofuels are touted as a mechanism for increasing energy security and potentially reducing greenhouse gas emissions, little is...

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...

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...

Societal dependence on insects for pollination of agricultural crops has risen amidst concerns over global pollinator declines. Habitat loss and lack of forage have been implicated in the decline of managed and native pollinators in the U.S. Northern Prairie Wildlife Research Center is conducting a regional research project to understand how land use affects honey bee colony health, and the...
