What we’re about
See 2024 schedule below!
We are National Park Service Weed Warriors and Arlington Regional Master Naturalists and we lead volunteers on the third Sunday of almost every month (we have a couple of Saturdays and some months off, see schedule below) 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

See all- NOVEMBER 17 Invasive Plant Removal at TRITheodore Roosevelt Island, Washington, DC
We are NPS Weed Warriors and Arlington Regional Master Naturalists and you should volunteer with us on Sunday, November 17 to learn about nature and remove invasive plants from everyone's favorite urban island.
Meet us at the entrance to the bridge (on the parking lot side, look for the sign) at 10:00 and bring your garden gloves and loppers/pruners if you have them. If not, we can provide gloves and tools. Wear long sleeves and pants and don't forget a water bottle.
We will have tasks ranging from easy (cutting English ivy and honeysuckle vines from trees) to hard (sawing down bush honeysuckle).
Parking at TRI can be tight if it's a pretty day. When the parking lot is full, you can park in Rosslyn and take the trail down. If you can bike or walk or take public transit, that's wonderful.
We'll see you there!
