MADISON - Wisconsin has 20 species of native bumble bees, and with many of these important pollinators in decline, creating habitat for them or helping monitor their populations are two of the most important steps concerned citizens can take for Pollinator Week this June 17-23.

"Our native pollinators are incredibly important to maintaining Wisconsin's native ecosystems, many fruit crops, and backyard gardens, but they need our help," says Jay Watson, the Department of Natural Resources' insect ecologist.

"Creating healthy habitat for pollinators and getting trained to help identify and locate bumble bees, Karner blue butterflies, and monarch eggs and caterpillars are great ways to help."

Gov. Tony Evers has joined governors from 48 other states to declare June 17-23 as "Pollinator Week." A pollinator is any animal that visits flowering plants and transfers pollen from flower to flower, aiding plant reproduction. In Wisconsin, native pollinators include bees (Wisconsin has 400 species of them, including bumble bee species), butterflies, moths, flower flies, beetles, wasps, and hummingbirds. Populations of some pollinators in Wisconsin, including several bumble bees and butterflies, are in decline, with potential widespread implications.

Globally, somewhere between 75 percent and 95 percent of all flowering plants - some 180,000 species in all and 1,200 crops -- need pollinators to help reproduce, according to the Pollinator Partnership, the organizer of the awareness week.

In Wisconsin, many of these flowering plants and the insects that pollinate them feed other wildlife and support healthy ecosystems that clean the air and stabilize soils, Watson says.

Pollinators are crucial for many Wisconsin agricultural crops too. Without pollinators, Wisconsin cranberry growers would lose three-quarters of their crop, apple growers would lose 80 percent, and cherry growers would lose 60 percent. In 2015, that would have added up to a whopping $134 million loss, according to the Wisconsin Department of Agriculture, Trade and Consumer Protection. Concern over declines in pollinators led that department to initiate development of the Wisconsin Pollinator Protection Plan in 2015.

Feed pollinators and help find them

Good habitat for pollinators will include a diversity of native plants, leaf litter or "unmanicured" green spaces, and minimal to no pesticide use, Watson says.

"Even if you only have a small yard or an apartment balcony, you can grow native flowers that provide food for pollinators," he says.

Lists of plants good for pollinators and other resources are found on DNR's Saving Pollinators web page, found on, search "pollinators."

Volunteering with a citizen-based monitoring program to help pollinators is something that anyone can do, wherever they are in the state, says Eva Lewandowski, citizen-based monitoring coordinator at DNR.

"There are several pollinator projects in Wisconsin that people can join to help provide high quality data that can be used for conservation and management," Lewandowski says. Those programs include:
