Over 3,300 campus landscapes coast-to-coast represent a continuum of landscape design spanning more than two centuries. In most cases, the central quadrangles of these grounds remain, but equally important supporting spaces and significant views and vistas are falling prey to campus parking and new building construction, forever altering these sylvan settings. These nationally significant landscapes represent the pioneering works of such masters as Frederick Law Olmsted (Stanford), Warren Manning (Amherst College), and Marian Coffin (University of Deleware) as well as more recent post-war visions by such California modernist landscape architects as Ralph Cornell and Thomas Church. A national strategy is necessary to reverse this trend.
