Land use was quantified within a 4-km radius around 36 apiaries in North Dakota, South Dakota, and Minnesota over two years, 2015-16 and 2016-17. The area (hectares) of Ag (corn, soy, small grains), Grass (pasture, grassland, fallow land, wildflowers, shrub land, and hay land), Wetlands (herbaceous and woody), and Bee crops (alfalfa, canola, sunflower) were quantified around each apiary in each year. Within each apiary, the average change in frames of adult bees among all colonies from June to September was calculated. Additionally, the average September Varroa mite infestation rate, the average adult population size during almond pollination, the count of colonies exhibiting queen events in September, and the count...
These data were collected to fulfill multiple Inter-agency agreements established by US Geological Survey and multiple partners: US Department of Agriculture-Farm Service Agency, USDA Natural Resources Conservation Service, and the Honey Bee Health Coalition. In this study USGS scientists conducted floral resource and insect pollinator assessments across multiple land covers in North Dakota, South Dakota, and Minnesota from 2015 to 2019. Sampling was done along 2x20m transects in June through September by a single observer. All transects were located on private or public grasslands such as Conservation Reserve Program (CRP) lands, Environmental Quality Incentives Program (EQIP) lands, managed pasture, haylands,...

These data describe land use (summed hectares of agricultural crops: corn, soy, and small grains), individual honey bee nutrition, honey bee colony population size, and proportional honey bee colony survival among 36 apiaries across Minnesota, North Dakota, and South Dakota.
This data release is for all plant and insect interaction observations collected by U.S. Geological Survey (USGS) researchers at Northern Prairie Wildlife Research Center. These data are publically available and searchable on the USGS Pollinator Library website, along with other non-USGS collected plant and insect interaction records. The aim of the Pollinator Library is to support management and research of plant-pollinator systems by documenting, synthesizing, and disseminating information on flowers that are utilized by pollinators and other insects. We hope that by providing free access to essential information, the Pollinator Library will lead to an improved understanding of the foraging needs of flower-visiting...
