Group hopes to use RAGBRAI to restore Iowa’s Monarch populations

The Register’s Annual Great Bike Ride Across Iowa (RAGBRAI) kicked off this week and one CGRER member is hoping to use the event as a opportunity restore Monarch butterfly populations in the Hawkeye State.

CGRER founding member David Osterberg and University of Iowa College of Public Health research support specialist Nancy Wyland organized an event last week inviting people to help make milkweed  “seed bombs.” These bombs consist of soil, compost, and milkweed seeds rolled into a ball – roughly the size of a golf ball – which will be distributed to RAGBRAI riders as they make their way through Mount Vernon Friday afternoon.

Riders are encouraged to toss these seed bombs in ditches along roads in Linn and Johnson County to bring back milkweed plants with the hope of restoring Iowa’s Monarch butterfly population. Estimates show a 90 percent decline in Monarch populations over the past 20 years.

Osterberg and his group helped create roughly 600 seed bombs as part of a larger effort spearheaded by Monarchs in Eastern Iowa, a group that aims to store Monarch populations in Eastern Iowa. Last year the group raised and released approximately 1400 butterflies.

Among the riders participating in this effort is Kelly “Milkweed” Guilbeau. The Grinnell resident, who sports a butterfly costume during the ride, first began tossing out seed bombs last year. Guilbeau also manages a blog which focuses on Monarch butterflies.

This year marks the 43rd anniversary of RAGBRAI with approximately 20,000 participants on this year’s ride.
