Among the leading pioneers of the eco-art movement, the collaborative team of Newton and Helen Mayer Harrison (often referred to simply as “the Harrisons”) have worked for over forty years with biologists, ecologists, architects, urban planners and other artists to initiate collaborative dialogues to uncover ideas and solutions which support biodiversity and community development. The Harrisons’ concept of art embraces a breathtaking range of disciplines. They are historians, diplomats, ecologists, investigators, emissaries and art activists. Their work involves proposing solutions and involves not only public discussion, but also community involvement and extensive mapping and documentation of these proposals in an art context. Past projects have focused on watershed restoration, urban renewal, agriculture and forestry issues and urban ecologies. The Harrisons’ visionary projects have, on occasion, led to changes in governmental policy and have expanded dialogue around previously unexplored issues leading to practical implementations variously in the United States and Europe. There is a large body of literature on their work.
