The datasets show the amount of Conservation Reserve Program land around registered apiaries in North and South Dakota from 2006-2016.

The coastal prairie of Louisiana is classified as a Tier 1 Habitat in the Louisiana Department of Wildlife and Fisheries’ Wildlife Action Plan, meaning that it is a priority habitat of primary conservation concern. Declines in pollinator populations worldwide have prompted questions about the role of such grasslands as habitat for pollinators. In this study, we surveyed bee populations and the plant communities present in the following three grassland types in southwest Louisiana: prairie remnants, restored prairies, and old fields.

We measured nesting rates and nesting success for a community of cavity-nesting bees across gradients of floral abundance, floral richness, and land-cover in the Prairie Pothole Region. Variables in this dataset include a unique transect identifier, a count of the occupied nests per transect, total floral species richness per transect, total floral stem abundance per transect, bee species richness, number of emerged adult bees per transect, and the proportion of those emerged bees which were female. In addition, there are land-cover measurements of the total area, in hectares, of grasslands, wetlands, and woodlands within 500m and 1500m of each transect. We binned land-covers from the 2019 National Agricultural Statistics Service Cropland Data Layer into our definitions of grasslands (Other Hay/Non Alfalfa, Sod/Grass Seed, Fallow/Idle Cropland, and Grassland/Pasture), wetlands (Woody Wetlands and Herbaceous Wetlands), and woodlands (Deciduous Forest, Evergreen Forest, and Shrubland).

This data release includes sampling location identification and timing data as well as plant and insect pollinator taxonomic information in Conservation Reserve Program fields. Sampling took place during July and August of 2019. Fields were located on private land managed for the U.S.Department of Agriculture Conservation Reserve Program in eastern central Iowa, U.S.A.

Data included in this data set are for blue vane trap captured native bees from Logan County, Colorado starting in 2012 and ending in 2014. Data were collected the number of bees captured per date, per field, and identified to genus. Net level data contains 16,229 records.

,Data files for manuscript titled "A checklist of South Dakota bumble bees (Hymenoptera: Apidae) ", https://doi.org/10.3897/jhr.94.94584.,Excel file with 4 tabs: Metadata, county maps, species data, and species matrix. Metadata is contained within Excel file that describes all variables for each tab.,Abstract from paper: Several bumble bee species (Bombus Latreille) are declining and efforts to conserve populations will be strengthened by an improved knowledge of their geographic distribution. Knowledge gaps exist, however, especially in central portions of North America. Here we report 29 species of bumble bees from South Dakota in the north-central USA, based on 130 years of records from 1891 to 2021. Specimens or observations were available for >90% of the 66 counties, though they were not distributed evenly as most records came from Pennington, Lawrence, Custer, Brookings, and Day Counties. The five most commonly collected or reported bumble bee species were B. griseocollis (54 counties), B. pensylvanicus (41 counties), B. fervidus (39 counties), B. huntii (27 counties), and B. bimaculatus (25 counties). Twenty species were recorded from 10 or fewer counties. Despite differences in occurrence, 66% of the Bombus species in South Dakota were collected or observed since 2020, including six of the nine species of conservation concern (B. fraternus, B. pensylvanicus, B. fervidus, B. occidentalis, B. terricola, and B. morrisoni). However, the critically endangered B. affinis, B. variabilis, and B. suckleyi have not been collected or observed for over 50 years. While this checklist is the first for South Dakota bumble bees in nearly 100 years, data are still lacking as ~55% of counties had fewer than five species reported. We suggest future efforts should focus on these under-sampled areas to fill in baseline knowledge of the wild bee fauna towards completing a more holistic view of bumble bee distributions across the Great Plains.,,

This data record includes bee species captured by pan trap or hand net in 1-hectare, mixed-grass prairie plots at Badlands National Park, South Dakota, in 2012.
