Help Butterflies, Bees And Other Pollinators During Pollinator Week

The Wisconsin Department of Natural Resources (DNR) encourages Wisconsinites to help native pollinators during Pollinator Week, June 17-23, and throughout the rest of the summer and fall.

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.

Air in Louisiana More Toxic Than Previously Thought

The presence of a dangerous chemical in the air of southeast Louisiana, is far greater than the U.S. Environmental Protection Agency estimated and exceeds safe limits, a study published Tuesday found. The levels of ethylene oxide, exposure to which can cause lung, breast, or other cancers, are nine times higher Ethylene oxide levels than the EPA estimated, the study, which was published in the journal Environmental Science & Technology. The new study found that the gas' presence averaged about 31 ppt and was far higher in certain locations within the industrial corridor, which runs alongside the Mississippi River from Baton Rouge to New Orleans. In each of the census tracts the researchers studied, the level of the gas was higher than the EPA had estimated for that area, in most cases significantly, with a median discrepancy of about 21 ppt. "We expected to see ethylene oxide in this area," Peter DeCarlo, an associate professor at Johns Hopkins University and an author of the study, told The Guardian, noting that it was "worrisome,"
"But we didn't expect the levels that we saw, and they certainly were much, much higher than EPA's estimated levels."
