Environmental Programs

Patapsco Heritage Greenway (PHG) organizes multiple stream cleanups every year in locations throughout the Patapsco Watershed. We believe that these events are crucial in preventing litter and pollution from contaminating our waters all the way to the Atlantic Ocean.

Litter that ends up in our streams and rivers is not only an eyesore, but also poses a serious threat to the aquatic ecosystems and the diverse wildlife that call them home. By participating in PHG cleanup events, volunteers help preserve and protect the natural resources of the valley and create a cleaner and safer environment for everyone.

Our stream cleanups are fun and engaging events that are open to people of all ages and abilities. They provide an opportunity for individuals and groups to come together and make a difference in their communities. In addition to cleaning up trash and debris, volunteers also learn about the importance of watershed conservation and the role they can play in keeping our waterways healthy.

Invasive plants can quickly spread and overtake an ecosystem, causing devastating effects on native species. The Patapsco Valley is no exception, and presence of invasive plants is a serious concern. At Patapsco Heritage Greenway, we understand the importance of protecting our local ecosystem and are committed to combating this threat.

Our invasive plant removal events are a significant part of our efforts to save the trees and protect the natural resources of the valley. Volunteers work alongside us to identify and remove invasive species that threaten the health of the local environment. We focus on a range of invasive plants, from vines like English Ivy that suffocate and weaken trees, to aggressive grasses that threaten the preservation of landmarks such as the historic Oella Cemetery.

Our goal is to not only remove these harmful plants but also to educate the community on the importance of preventing the spread of invasive species and the benefit of planting and maintaining native plants. Through our efforts, we hope to promote a more sustainable environment for all who live and visit the Patapsco Valley.

At PHG’s tree planting events, volunteers have the opportunity to get involved in a variety of tasks, including digging holes for the native tree saplings, placing trees in the ground, and securing protective structures around the newly planted trees. Planting trees is crucial for the environment, as they absorb carbon dioxide and provide oxygen. Trees also play an important role in preventing soil erosion, stormwater runoff and providing wildlife habitat.

However, planting trees is just the beginning. Proper tree maintenance, such as periodic watering, weeding, and mulching, is essential to ensure the survival rate of newly planted trees. By participating in our tree maintenance events, volunteers help to increase the likelihood of the trees’ survival, which leads to the long-term benefits of a healthier environment and greener community.
