There are dozens of modern buildings listed in the National Register of Historic Places and as National Historic Landmarks - In fact, to date, there are more than 1,000 structures that have been designated that are less than 50 years old and only a small number of works of landscape architecture. Although properties such as the Glass House, the Gropius House and Russell Wright's Manitoga have been designated as National Historic Landmarks including significance in landscape architecture, there are countless others from the Eames House (which is very much about landscape, and yet possesses no landscape significance) to significant projects by Lawrence Halprin, Dan Kiley, and M. Paul Friedberg that have not been recognized. Even worse, Friedberg's seminal masterwork, Peavey Plaza (Minneapolis, MN) is now facing the wrecking ball, while a road expansion threatens Kiley's landscape at the Cathedral of the Immaculate Conception (Burlington, VT) and Halprin's Riverbank Park has been the target of an generic and uninspired new design (Flint, MI).

What role can architects, landscape architects, historians, historic preservation professionals, journalists and bloggers do to instill value for the legacy of landscapes?

What can and should be done to nurture an informed public debate about the legacy of modernist landscapes and reverse the trend of demolition?
