Pollinators are in peril.
Dire reports of colony collapse disorder, an umbrella term for steep population declines, have been making news for several years. Earlier this month, the U.S. Department of Agriculture released a study finding that 31 percent of honeybee colonies died over the winter.
That's troubling for all of us, not just science and bee geeks, given that a third of the plants in our diet are pollinated by honeybees.
"It's not just a gardening issue, it's a food-safety issue," said Elizabeth Beckman, education coordinator for the Capitol Region Watershed District.
Bee deaths are a complex problem, with multiple suspected causes, including disease, habitat loss, pesticides and climate change, said Elaine Evans, a bee scholar and doctoral candidate in entomology at the University of Minnesota.
But there's one simple thing that everyday Minnesotans can do to help the bees: Plant habitat for foraging and nesting. Particularly native wildflowers. Ideally, in big clumps so bees can find them easily.
"Bees need abundant flowers, from April through September, and they need diversity," said Evans. (Corn and soybeans, the state's top agricultural crops, don't provide nectar for pollinators, she noted.)
Bees also need undisturbed areas for nesting, Evans said. "They nest in the ground and need land that's untilled, that's left alone."
