 A square pier was built in the center of the footbridge connecting Heritage and Kingman islands, providing a place for bird watching, fishing, and for pedestrians to rest and view the marshes.The islands were home to more than 100 species of birds as well as mimosa trees, purple loosestrife, Queen Anne's lace, and turtles.The D.C. government turned over maintenance of the islands in 2009 to the nonprofit group Living Classrooms, and the city continued to plan for an environmental center and more trails.
