(Portland, OR)  --  A new federal project has honeybees making themselves at home on the roof of the Edith Green-Wendell Wyatt Federal Building in downtown Portland.  The General Services Administration is putting honey bee hives at eleven facilities across the country as part of a yearlong pilot.  Two hives with 40-thousand bees are located at the top of the Portland federal building.  The Best Bees Company, a major beekeeping service, will maintain the hives, analyze honey production and identify the plants the bees are using.  The pollination that bees provide are vital to agriculture and food production.
