1) Refine the pollinator model to allow for the estimation of the number of hives that can be supported in any given landscape setting 2) Extend the pollinator model to address interactions between weather, land cover, and bees that affect levels of honey production 3) Integrate the findings from the USDA-ARS field study into the pollinator model to refine forecasts of how land-use features in the PPR affect national agricultural pollination services [see Narratives for more information.]

This data set consists of data collected during 2012 in Badlands National Park in South Dakota that were used in the analysis in support of the PLOS One article titled "Exotic plant infestation is associated with decreased modularity and increased numbers of connectors in mixed-grass prairie pollination networks". The data consist of three spreadsheets. An insect richness, interactions, and flower count data set is a summary of counts of individual flowers (by species) and insects captured on flowers (that were found to carry pollen) over the course of a study on the effects of infestation by Cirsium arvense on pollinator interactions with native plants. Three dominant exotic plants, C. arvense, Convolvulus arvensis,...

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...
Badlands National Park is home to nine plant species considered rare in South Dakota, as well as several invasive exotic plants, many of which vie for pollinator services with the rare species. The purpose of this study was to document the interaction webs that link rare and invasive plants with pollinators and, consequently, with each other. Understanding these linkages will guide management of both the rare and invasive species. The list of insect species associated with the webs and ancillary trapping will provide a baseline assessment of the pollinator fauna at Badlands National Park which can be expanded upon and reassessed over time and in response to climatic changes. To date, 236 bee species have been...

Honey bee colonies located in 2 apiaries in North Dakota were fitted with two types of monitoring device: pollen traps and scales. Data were collected from devices periodically throughout the 2014 season (May-October). Data derived from pollen traps included: the total fresh weight of pollen collected, the percent crude protein content, the percent content of each amino acid, and DNA identification of floral plant sources. Scales collected colony weight through time.
In this study US Geological Survey scientists collected pollen samples from honey bee (Apis mellifera) colonies distributed across North Dakota, South Dakota, and Minnesota, in 2015 and 2016. Sequencing of nuclear ribosomal loci was used to determine the number and abundance of flowering plant taxa. The data contain counts of Operational Taxonomic Unit (OTU) reads of honey bee collected pollen from apiary locations throughout the growing season.

This dataset includes pollen sample weight in grams and percent crude protein collected by honey bees (Apis mellifera) across 38 apiaries in Minnesota, North Dakota, and South Dakota approximately weekly from June through September in 2015 and 2016. Additionally it includes the hectares of different land covers (corn, Zea mays, & soybeans, Glycine max, grasslands, bee forage crops, and wetlands) located within a 4 km radius of each apiary.
Colony Collapse Disorder has resulted in widespread loss of US honey bee colonies and heightened societal concern over honey bee health and reduced pollination services for agricultural crops. The Farm Service Agency has expressed substantial interest in promoting habitat for honey bee colonies residing on Conservation Reserve Program (CRP) lands throughout the Great Plains. Our team is conducting a multi-state study to identify specific plants that can be readily implemented into the CRP for improving pollinator health in North Dakota. This study will provide managers with a means to evaluate cost-effective seeding mixes to benefit pollinators for multiple conservation programs. This project was started in 2015...

Pollinator declines have emphasized the need for a greater understanding of plant-pollinator networks and land management activities that improve pollinator habitat. 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 insects and plant-pollinator systems. https://www.npwrc.usgs.gov/pollinator/
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.
Here we compare pollen identification results derived from light microscopy and DNA sequencing techniques of a robust number of samples collected from honey bee colonies embedded within intensive agricultural landscapes in the Northern Great Plains. We collected pollen samples from colonies within 6 apiaries in 2010 and 2011. For each pollen sample, we identified pollen grains via light microscopy and provide the number of grain counts-per-million. A separate aliquot of each pollen sample subjected to light microscope identification was also used for DNA sequencing analysis. We provide the plant operational taxonomic unit (OTU) for all base pair reads as the number of reads-per-million.
