Landslide 2009: Shapers of the
American Landscape
Landscapes at Risk
The goal of TCLF’s Landslide program is to draw immediate attention to endangered (or threatened) nationally significant cultural landscapes. In establishing this program, TCLF aims to serve as a catalyst for an informed discourse in the hopes of encouraging responsible community involvement and wise stewardship decisions. The posted web features are written by outside individuals and do not necessarily represent the opinions of TCLF.
Landslide in Action!
Landslide is designed to educate and thereby rally support at the local, state, and national levels by calling attention to endangered landscapes and cultural landscape resources that are in and near your own community.
Landslide is an interactive, online resource highlighting threats to cultural landscapes and directing the public to those groups working to protect them. Landslide provides a history of each threatened site; presents its social, cultural, and artistic significance; gives a biography of the landscape architect or designer; and details the current threat. Moreover, Landslide connects the public to the preservation effort by providing links to the groups that are working to safeguard each site for the benefit of today and for future generations.
Saved and Lost !
Thanks to public advocacy and education many of these endangered landscapes have been preserved for future generations. Unfortunately, for some, it was too late.
