RESULTS
During 96 half-hour netting periods along standard 100 m transects, we recorded 792 honey bees and 2,342 native bees visiting 14 plant species across 15 meadows in the Central Sierra Nevada in California, USA (Table S2). Just over forty percent of floral visits were to C. quamash , which we chose as a focal species because of its consistent abundance, its cultural relevance, and its ecological importance. Honey bee abundance in meadows, measured as the total number of honey bees visiting flowering plants during morning and afternoon netting transects, ranged from 0 – 184 bees per hour per 100 m transect while the abundance of native bees ranged from 10 – 261 bees. The abundance of honey bees visiting C. quamash ranged from 0 – 65 bees and native bees ranged from 0 – 63 bees.
