Biofuels
USGS scientists are evaluating the potential for and consequences of biofuel production. Their research is answering questions such as, what happens when biofuels are incorporated in different soil types and landscapes? What effects does biofuel production have on pollinators and their habitats, dust production, or water quality and quantity?

Evaluation of conservation grazing versus prescribed fire to manage tallgrass prairie remnants for plant and pollinator species diversity
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...
Quantifying the effects of land-use change and bioenergy crop production on ecosystem services in the Northern Great Plains
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...
The pollinator library: a decision-support tool for improving national pollinator conservation efforts
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...
Long-term changes in pollinator resources (alfalfa, sweetclover, milkweed) and monarch butterfly populations in CRP grasslands
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...
Improving forage for pollinators on Federal conservation lands
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...
Understanding how land-use change in the Northern Great Plains affects pollinator health and pollination services
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...
Biofuels in the Southwest
Concerns about energy security and rising greenhouse gas emissions have stimulated an unprecedented increase in the push for alternative energy use, including the use of plant biomass as a source of renewable energy (bioenergy). However, meeting alternative energy goals, while also meeting food demands and mitigating potential detrimental effects of industrialized agriculture, has emerged as a...
