In August 1997, a group of landscape architects began preparations for an exhibition on eco-revelatory design. From this they hoped to promote and evaluate what they claimed was an emerging field in landscape architecture. Eco-revelatory design is landscape architecture that reveals and interprets ecological phenomena. It highlights the aspects of a site that are invisible or overlooked by designers and the public in the hope that this will enliven the site, make people more aware of its complexities, and promote ecological awareness. Now, almost ten years after the exhibition, this thesis examines eco-revelatory design: some of its projects, its criticisms, many of its basic assumptions, and its evolution. By reviewing early works, criticisms, and later works of eco-revelatory design this thesis questions the assumptions eco-revelatory designers make, and traces the evolution of the practice. Hopefully, this will provide a snapshot of where eco-revelatory design currently stands, and where it might go in the future.
