Butterbike Monarch Presentation & Walk

Each spring, millions of monarchs leave the mountains of Central Mexico, where they survived the winter, to begin their annual migration north. This spring, they are accompanied by cyclist Sara Dykman from Kansas who is biking 10,000 miles from the overwintering colonies in Mexico to Canada and back with the monarchs. Or as she would say “Butterbiking with the butterflies.” Dykman’s goal is not only to follow the monarch migration, but to connect people living along the route with the migration. In order to do this she visits classrooms, wildlife refuges, and nature centers to talk about bike touring, the monarch migration and what we can do to help protect this endangered natural phenomenon.

Please join us at the Refuge Visitor Center at 6PM for a Powerpoint presentation on Sara's journey, to be followed by an outdoor walk on the Refuge trails to look for pollinators. Please RSVP to Ranger Katie at
