IMU had a great time volunteering with Washtenaw County Parks Sunday afternoon from 2-4pm at Parker Mill off Geddes Rd. in Ann Arbor, MI. We spent our time working underneath a huuugeeee oak tree we learned has probably been there since at least the 1820s. We were pulling invasive weeds (mostly bitter cress) from this wooded area in the park. Parks Naturalist, Shawn Severance, was a great leader and teacher. We learned about the land's history, invasive weeds, the vitality of insects in nature, poison ivy, forest burns, and so much more.
