The Living Barge Project was a large-scale, temporary public art installation by artists Sarah Kavage and Nicole Kistler with the backing of South Park Arts that was moored on Seattle’s Duwamish River during April 2006. An industrial barge was filled with approximately 400 native plants, creating a temporary floating island full of ferns, shrubs and tree seedlings. At the end of the project, volunteers planted the plants from the Living Barge at Cesar Chavez Park in South Park.
