Environment Program

At the heart of the Patapsco River Valley is a network of protected lands along the Patapsco River representative of Maryland’s Piedmont forest and industrial heritage. The Valley’s natural beauty and history combine to provide a unique opportunity for visitors to appreciate and enjoy Maryland’s most dramatic river valley.

The Patapsco Heritage Greenway rallies thousands of volunteers each year to clean up trash, remove invasive species, and plant trees in support of its mission to preserve and protect the natural resources of the valley.

What You Can Do

PHG has recruited a strong environmental team of volunteers. You can become active in the fight to sustain our natural resources by becoming a part of our team. You can become a certified Stream Watcher, or simply participate in stream cleanups and tree plantings with no prior experience necessary.

Through these coordinated environmental programs we provide volunteers the opportunity to make a positive difference in the health of the Patapsco River and ultimately the Chesapeake Bay.
