  1. The Impact of ROW Management on Apiary Populations Gary S. Reuter, University of Minnesota www.beelab.umn.edu

  2. Your breakfast without bees Scientific American April 2009 Value of crops in US that depend on pollination: >$18.9 billion $217 billion worldwide

  3. Alfalfa Hay – Bee Pollination – Dairy and Beef

  4. Your grocery store without bees

  5. Healthy Bees Healthy Food Healthy Lives

  6. Honey Bees

  7. Decline in U.S. honey bee colonies 1945-2007 Since 2007, 30-40% of all honey bee colonies die annually Beekeepers struggle to replace losses

  8. Wild Bee Pollinators Also in Decline Leafcutter bee Miner bee Bumblebee Orchard Mason bee Sweat bee

  9. Wild Bee Nests Tunnel-nesting (~30%) Ground-nesting (~70%) Photo: Matthew Shepherd

  10. Wild Bees: Larva feeds on pollen ball provisioned by mother bee

  11. 750,000 acres of almonds in Central CA requires 1.5 million colonies of honey bees for pollination No Bees, No Nuts

  12. 72,000 acres of blueberries across U.S. requires 150,000 colonies of honey bees for pollination No Bees, No Berries

  13. Colonies trucked in and out because after bloom there are no flowers and many pesticide applications

  14. Protect Bees Food If there are flowers blooming, there will be bees foraging

  15. What bees eat • Pollen - protein • Nectar – carbs • Water Pollination Happens

  16. “Bee”Flowers • Major Honey Plants • Clover • Alfalfa • Basswood • Buckwheat • Wildflowers/ weeds • Mustards • Vetch • Dandelion • Goldenrod • Sumac • Trees - pollen • Maple • Willow • Oak • Gardens/ fruit trees • Vine crops • Berries • Canola • Apple

  17. Bees collect corn pollen but only when hungry (low protein content) Bees may collect nectar from soybeans in MN only when hot and humid

  18. Bees forage 2.5 miles from colony, on average

  19. What can the public do? Plant flowers! www.xerces.org/pollinator-conservation/ • Pay attention to neonicotinoid systemic insecticide use, especially in urban landscapes! • Plant bee gardens • Encourage roadside plantings of flowers • CRP land: put legumes in mix
