Why we do it

The answer is as clear as a sunny afternoon on the trail. See the dozens of joggers, bikers, and children walking with parents—all surrounded in natural beauty. You’ll understand.

Native Plants

naturally good neighbors
Over centuries, native plants evolved together with birds, butterflies and other species to create a balanced, healthy environment.

Alien Invasion!

Not little green men, but little green plants from across the seas—often beautiful, but frequently evil. Many are brought here as decorative ground cover. Sometimes they arrive as hitchhikers.

Monarch Hatchery

Observe, both in the wild or at our children-friendly hatchery, the monarch butterfly growing from egg to caterpillar, caterpillar to chrysalis, and chrysalis to majestic monarch.

Volunteer and Support

We need your help. The Friends of the Green Bay Trail is an entirely volunteer organization. Join us when you can.

What we do

We are environmental stewards of the Green Bay Trail, restoring a natural,  prairie eco-system. Our goal is to make the trail a national example of the healthy intersection of nature and culture that inspires community and individual well-being. LEARN MORE

Friday Fun Facts – Did you know?

Go North Young Postman

Before Grubhub and Domino’s, the earlies deliveries on the Green Bay Trail were done by the Post Office. In the beginning of the 1800s the trail was used as a delivery route between Fort Dearborn in Chicago and Fort Howard in Green Bay, Wisconsin.

Body Heat

The cold-blooded fact about Monarchs is that they are cold-blooded, which means they cannot regulate their own body temperatures. If the air temperature falls below 55ºF, butterflies are unable to flee from predators or feed. Butterflies fly with ease when air temperatures range between 82º-100ºF.

Support the Trail with a tax deductible contribution by December 31, 2019.
Your investment at any donor level will ensure the necessary care and continued maintenance to sustain the beauty of the Green Bay Trail for years to come.
