Photo catalogue of Arlington's Invasive Plant Program. Photos are sorted by parks. Most photos are of work sites - the same shot taken over time to document our progress and changes at the site. Other photos are of volunteers, known as Remove Invasive Plants (RiP) volunteers. Volunteer photos are in Volunteer Photo Galleries for each park. The Great Volunteer Shots Gallery highlights some of our best volunteer photos from all sites and the Great Staff Shots Gallery shows our great staff in action.
