(DC) (Rock Creek Conservancy) Join Rock Creek Conservancy, the National Park Service, and Weed Warrior Leader, Kathy Sykes for this invasive plant removal restoration event in Rock Creek Park. Invasive plants are a major threat to our fragile forests, and stopping their spread helps allow native plants to thrive in the understory. This event is part of an area-wide volunteer-powered effort to help rescue our public parks and green spaces from non-native invasive species.
