The Patapsco Heritage Greenway will offer volunteer naturalist training from 6 p.m. to 9 p.m. Tuesdays, July 7 to 25, at Catonsville Community College and from 9 a.m. to 3 p.m. Saturdays at the Avalon Area of Patapsco Valley State Park.

Participants must be at least 18 years old.

The volunteers will learn about plants, trees, wildlife, streams and ecology as well as Native American and local history of the area.

After completing the training, the volunteers -- who will be known as Greenway guides -- will be asked to lead at least four walks along the greenway's trails.
