Butterflies at the Bolingbrook Golf Club

By Julianna Gerdes

While the thought of playing a round of golf at Bolingbrook Golf Club may bring butterflies to your stomach, Bolingbrook’s meticulous greens and perfectly pinstriped fairways offer more than just the familiar feeling of excitement. Though numerous types of butterflies find a home on the course, Bolingbrook takes special pride in their extensive monarch butterfly population.

The monarch butterfly population has drastically declined over the past twenty years, to the point that the U.S. Fish and Wildlife Service is considering putting this important pollinator on the Endangered Species List. The Village of Bolingbrook and the Bolingbrook Golf Club have been working for many years to make Endangered Species Listing for monarchs unnecessary. When the Village constructed the golf course in 2002, Mayor Roger Claar and the Village Trustees put the environment at the forefront of the design plans. The course includes wetland plantings, numerous lakes, and over 100 acres of native prairie and grasslands, which are the perfect habitat for monarchs. Just as the Village offers numerous restaurants and dining experiences for its residents, the native prairie offers a smorgasbord for the monarchs to feast. The fescue areas are abundant with Wild Carrot, Goldenrod, Thistles, Joe Pye Weed, and various types of milkweed. The most preferred plant of them all is the Swamp milkweed, but monarchs do enjoy any variety of milkweed available.

The Club annually harvests milkweed seeds of different types from the native areas. It propagates those seeds and plants them in new locations on the course the following spring. Along with starting new seeds in containers, the Club also directly sows the seeds into new locations. This is done by aerifying the ground first, then dropping the seeds into the aerified locations. Milkweeds are the only plants that monarchs will lay their eggs on, which is why the plant is so critical for their success and why Bolingbrook increases its milkweed population every year. Jeff Gerdes, Golf Course Superintendent, has utilized maintenance practices since the club opened to ensure the monarchs are happy. The course uses organic fertilizers such as chicken manure, and recycles effluent water to irrigate the course. These are great sources of natural nutrients and allow for the reduction in use of manufactured fertilizer. The native fescue areas are maintained with prescribed burns rather than the use of herbicides for controlling weeds. These burns are done only after the first frost has occurred, instead of in early fall, giving monarch chrysalises on the milkweed as much time as possible to hatch. “We want to do all that we can to protect and promote the beauty Mother Nature and her resources provide to Bolingbrook. Bolingbrook Golf Club is proud of the efforts made, and the results from these practices ensure that our wildlife and natural habitats are cherished and not taken for granted,” said Gerdes.

In addition to the 100-plus acres of native areas, the course has created several pollinator gardens throughout the grounds. These gardens have showy annuals and perennials preferred by monarchs, bees, and hummingbirds. The gardens provide a great food source through Coneflowers, Butterfly Bushes, Asters, and Columbines, just to name a few of the colorful flowers.

Several residents of the community participate in the monarch efforts at the club, as well. Cindy Hennessy and Peggie Mcmillan have donated numerous varieties of milkweed seed to the club and harvested other varieties of seed from the course. Hennessy has also promoted monarchs by supplying butterfly kits to schools, libraries, and many other organizations as an educational tool to inform the public of the fragile future for monarchs. In addition to their work at the Club, they have worked with Mayor Claar to create butterfly gardens throughout the Village of Bolingbrook.

The golf course works closely with several organizations as part of the monarch preservation process. The golf course is a registered Monarch station (#21889) with the Monarch Watch organization. Bolingbrook Golf Club was also one of the initial clubs to join “Monarchs in the Rough,” which is a program sponsored by Audubon International. Both of these organizations have specific criteria for monarch habitats that have to be met and maintained to stay in good standing. Also, The Conservation Foundation, a DuPage Monarch Project partner, determined Bolingbrook Golf Club has an environmentally friendly landscape and certified it through their Conservation @Work program.

This year the club and community are working with the Chicago Field Museum and will participate in new initiatives created by the museum to further promote monarchs.

Bolingbrook is very excited about the success they have had and are expanding their efforts for the future. They are hopeful that others will learn of the importance of monarchs as pollinators in the ecosystem, and also take measures to save the monarchs. If you want to enjoy monarchs and the beautiful habitat they live in, all you have to do is visit Bolingbrook Golf Club.
