It won't grow
without you.


The trail ahead.

The Treeline is an urban trail connecting the best of Ann Arbor. It will be a defining feature of our geography, providing a common place to explore, bike, run, and reconnect with nature—and each other.



Because of you, 2021 was a year of accomplishments that brought the Treeline ever closer to reality. Learn where the trail lies by reading our 2021 Annual Report.


Join us on the trail.

It’s all of our responsibility to grow the Treeline. Find out how you can lend a hand by volunteering, spreading the word, and donating.
