Most alien plants don’t spread, but a few with no natural predators will take over and cover everything. Invasive species are the biggest threat to our native plants and animals after habitat loss.  Learn to identify native plants versus invasive weeds and use hand pulling or other techniques to control their spread. Join in at a location near you!

Please see the individual links below for each Maryland county that has submitted information.  Be sure to contact each sponsor to confirm locations and schedules.

Invasive Plant Removal in Northern Virginia

National Park Service, George Washington Memorial Park
Various rolling locations: Turkey Run, Glen Echo, Fort Marcy, Theodore Roosevelt Island, Jones Point, Roaches Run, Daingerfield Island, Dyke Marsh, Fort Hunt
Every Friday: 9 am to 11 am

Join our team in identifying and removing non-native plant species that are negatively affecting our National Parks. Help us reduce the threat of non-native invasive plants, protect rare species and restore the biological and cultural integrity of National Park Service lands. Invasive plant removal requires walking on uneven and occasionally rocky terrain, and using hand tools (hand-saws, bow-saws, loppers, or hand-clippers) to cut invasive plants. Additional physical demands occasionally include the use of shovels and trowels while planting native plants, hauling excess debris, and standing for prolonged periods. Please wear work clothes (long sleeves and boots, etc.); we will provide tools and gloves but feel free to bring your own. Experience not necessary but we will be providing more formal training sessions in April.

We will feature a different location every week. For specific information, please contact us to join our list serv. Exact and advance schedule announcements will be sent out to those on the list serv.

Ecological/Historical Studies

Dumbarton Oaks Park is a vibrant, urban park, designed by Beatrix Farrand, America's first female landscape architect, between 1920-1940. The Park is the wild garden of Robert and Mildred Bliss's estate, Dumbarton Oaks. The formal gardens, owned by Harvard University are well known, however it is in the wild garden you will stroll along a romantic stream with 18 small waterfalls and through garden rooms of forest, meadow and stream side communities. DOPC is actively restoring the Park in partnership with Rock Creek Park to ecological health and beauty.The Park was succumbing to the effects of urban stormwater runoff and invasive plants when DOPC intervened in 2011. DOPC will work with you to facilitate your research and study ideas. Please contact for more information.

Invasive Plant Removal Day – Register Your Site TODAY!

All across the mid-Atlantic states

Invasive Plant Removal Day started as a statewide event in Virginia aimed at engaging volunteers in managing invasive plants in natural areas across the Commonwealth. We're proud to have expanded the effort across the mid-Atlantic region to include seven states (DC, DE, MD, NJ, PA, VA, WV). Groups such as Master Naturalist chapters and neighborhood organizations plan, organize, and run invasive plant removal events in their local communities. The events are posted on a central site, and volunteers are invited to find an event near them, and contact the event's organizer to register.

Potomac Conservancy

Potomac Conservancy's Growing Native is a year-round volunteer project that helps to restore and protect rivers and streams in the Potomac River watershed. Volunteers of all ages and backgrounds participate in Growing Native by collecting native tree seeds and planting trees along streams and rivers across the region. Not only are participants creating forests for tomorrow, they are also learning the important connection between healthy, forested lands and clean water.

Since Growing Native's inception in 2001, nearly 30,000 volunteers collected more than 94,000 pounds of acorns, walnuts, and other hardwood tree seeds. These seeds have generated seedlings that will be used to restore sensitive streamside lands.

Growing Native's efforts culminate in the fall, when we do large scale outreach to individuals, community groups, and local businesses to get involved while seeds are dropping on the ground! We invite people to volunteer by acting as Growing Native ambassadors, seed collection event coordinators, and Drop-off site coordinators.
