A pollinator is any animal that visits flowering plants and transfers pollen from flower to flower, which helps plants grow fruits and seeds. Most of Wisconsin's pollinators are insects like bees (Wisconsin has 400 native species, including 20 bumble bee species), butterflies and moths. Wisconsin's pollinators also include hummingbirds and some beetles and flies.
"There's a special connection between our native pollinators and the natural areas that make Wisconsin so unique. The federally endangered Karner blue butterfly and rusty patched bumble bee are more abundant in Wisconsin than many other parts of the country," said Jay Watson, DNR insect ecologist. "These endangered species as well as Wisconsin's other native pollinators need our help. Getting trained as a volunteer or creating a healthy habitat for them in your backyard garden is a great place to start."
In addition to supporting rare pollinators, flowering plants provide food to common pollinators, other insects, people and wildlife. They also support healthy ecosystems that clean the air and stabilize soil. Despite the importance of native pollinators, many are facing population declines.
Here are some ways Wisconsinites can help pollinators:
Tips For Gardeners
- Plant native plants and trees. Early blooming trees are an important food source for bumble bee queens emerging from hibernation and many other insects, which in turn provide food for birds and bats. Flowers that bloom throughout the growing season, like columbine, bee balm and goldenrod, fill your garden with colors for months while providing food to pollinators.
- Familiarize yourself with and plant native host plants for butterfly larvae that work with the sun and soil in your yard. Many butterflies depend on specific plants for their lifecycles, like common milkweed (monarchs), violets (meadow fritillary) or dill, fennel and parsley (black swallowtails).
- Provide water and shelter. Pollinators need water to drink and safe places to rest, avoid bad weather and spend the winter. You can maintain brush and leaf piles, avoid trimming hollow-stemmed plants through the winter and provide water such as a bird bath.
- Maintain a yard free from pesticides and herbicides. Insecticides can harm or kill pollinators, and herbicides can kill the plants they need to survive.
Volunteer And Support Opportunities
- Become a trained volunteer with the Wisconsin Bumble Bee Brigade, Wisconsin Karner Volunteer Monitoring Program or Monarch Larva Monitoring Project.
- Sign up for the State Natural Areas Volunteer Program. Volunteers clear brush, remove invasive species and collect native seeds.
- Support pollinator conservation efforts with a donation to the Endangered Resources Fund.
