The rusty-patched bumble bee (Bombus affinis) is a listed species under the Endangered Species Act of the United States. While understood to be a highly generalist forager, little is known on the role that limited floral resources or shifting floral community composition could have played in B. affinis decline. Determining which floral species provide suitable B. affinis forage could assist conservation efforts where B. affinis persists, identify floral species for restoration efforts, or highlight regions to search for cryptic populations.
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...
