ST. PAUL, Minn. (AP) -- Researchers say the honeybees on the roof of the Minnesota Institute of Arts have been thriving.
Minnesota Public Radio News (http://bit.ly/1l69x6B ) reports that the bees are healthy, producing lots of honey and breeding. Museum staff and researchers from the University of Minnesota Bee Squad watch over the rooftop beehives.
The Bee Squad manages a dozen rooftop operations across the Twin Cities. The 11-member research unit also teaches bee colony care and advises beekeepers.
Researchers hope to address a widespread decline in bee populations. About half of the bees in Minnesota died during the harsh winter.
Minnesota is one of the top honey producing states in the country. It is home to more than 350 bee species.
