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.

Ann Arbor's city parks sit on the ancestral and traditional homelands of several indigenous Native peoples. Read a land acknowledgement from the city and learn more about the early history of the land here.
The land that became Hannah Nature Area was deeded to the city in 1969 by the developer of the surrounding neighborhood. To learn more about restoration efforts by neighbors at Hannah, read this Natural Area Preservation (NAP) newsletter:
