The 3 miles of trails in Bird Hills give some lovely views of the Huron River. This is the largest Nature Area in Ann Arbor, and provides a great space to get out and see wildlife and wildflowers. Volunteers are needed to help remove invasive weeds like Japanese hedge parsley throughout the park. This is a great workday for the family. Join us at the Bird Road entrance to this park, west of Huron River Drive (additional parking in Barton Nature Area Dam entrance). Please wear long pants and closed-toe shoes. Every participant must present a completed release form, and all minors should be accompanied by a guardian. Tools, snacks, and know-how provided.
