Hannah Nature Area is a small 1-acre wooded ravine nestled between houses with a steep and winding trail. View the Ann Arbor Parks and Nature Areas map for location context. Removal of invasive plants here has allowed large stands of native jewelweed and false Solomon’s seal to bloom in this park, along with many other native wildflowers. There are a couple of natural groundwater seeps too, with irises growing in them. Cooper’s Hawks sometimes nest in the tall trees, and Eastern Phoebes are regularly seen in spring and summer, catching insects over the seeps.
