Data and code supporting: Pollinator plantings in the intensively farmed Midwest support a core set of common bee species, regardless of local and landscape controls

Amidst widespread habitat loss and homogenization of landscapes, pollinator plantings can provide bees with a diversity of foraging resources. Yet, such plantings may fall short of restoring historical bee communities. While previous studies have sought to investigate which factors contribute to effective plantings for bee communities, lack of experimental control may have limited their ability to tease apart planting effects versus effects from study design artifacts (e.g., collinearity and spatial autocorrelation). We conducted one of the largest randomized, landscape-level experiments to date in order to examine the degree to which planting size, seed mix type (low cost honey bee (HB) mix vs high cost native bee (NM) mix), and the percentage of natural land surrounding habitat plantings affect native bee diversity, abundance, and composition, in addition to floral abundance, richness, and area. We selected 38 sites for plantings with a fully factorial design, varying sites by seed mix type, size, and proportion of surrounding natural landscape.
