Less than 1% of the original tallgrass prairie remains and that is fragmented throughout the Great Plains region. Conservation and restorative efforts include varying degrees of burning, haying, and grazing tallgrass prairie. Insects also have vital roles in maintaining those last remnants of the prairie, including herbivory and pollination. Bees are the most important pollinators of flowering forbs which are an integral part of prairie plant diversity. However, not all bee visitations result in pollination, so it is important bee species diversity is high to aide in dispersal of flowering plants. This study examines the effects of prairie management on native prairie bees in western Minnesota. Results show managing a prairie by burning and haying have the highest species richness (71 and 53 species found respectively on burned and hayed prairie) and burned and hayed prairie show the highest species diversity (Shannon-Wiener diversity index=H’=3.13 and 3.17) of bees. Grazed and unmanaged prairie show low species richness (27 and 26 species respectively). Bees collected in bowl (2005, 2006), Malaise (2004, 2005), and flight intercept traps (2004, 2005) were identified to species; 93 species were collected from 5 families.
