We are National Park Service Weed Warriors and Arlington Regional Master Naturalists and we lead volunteers on the third Sunday of almost every month (see schedule) to stamp out invasive non-native plants at Theodore Roosevelt Island.
This work is vitally important to protecting the region’s remaining pockets of biodiversity. In many natural areas, plants that have co-evolved with birds and other local wildlife over thousands of years are being overwhelmed by fast-growing introduced species that strangle trees and eliminate food sources.
As a volunteer, you will:

• Work outdoors in woodlands, meadows, wetlands and other natural spaces
• Learn about invasives and native flora and fauna from Master Naturalists leading the activity
• Help remove non-native invasive plants so that native plants that support native wildlife will grow
• Interact with the public to explain our work

Come join us!
