The Cultural Landscape Foundation (TCLF) is a 501(c)(3) non-profit organization that provides people with the ability to see, understand and value landscape architecture and its practitioners, in the way many people have learned to do with buildings and their designers.

Your gift to TCLF is tax deductible to the extent allowed by law and will ensure TCLF's programs and ongoing initiatives collectively tell the stories of our nation's rich landscape heritage.

TCLF's Fifteenth Annual Silent Auction

Register now to bid on more than 90 fantastic works by award-winning landscape architects, artists, photographers, and allied professionals.

Bidding is available online starting October 22nd, and in-person and online bidding will end concurrently at the conclusion of the EXPO, November 17th at 2pm.


The auction is sure to be a highlight of the ASLA Annual Meeting and EXPO at the San Diego Convention Center. Proceeds benefit the Pioneers of American Landscape Design Oral History Project, an ever-growing, award-winning series of videotaped first person interviews with significant practitioners.

About TCLF

A non-profit established in 1998, The Cultural Landscape Foundation (TCLF) connects people to places. TCLF educates and engages the public to make our shared landscape heritage more visible, identify its value, and empower its stewards. TCLF achieves this mission through the ongoing development of its three core programs:

  • What's Out There, North America's largest and most exhaustive database of cultural landscapes;
  • Pioneers of American Landscape Design, an in-depth multimedia library, inclusive of video oral histories, chronicling the lives of significant landscape architects and educators;
  • Landslide, an ongoing collection of important landscapes and landscape features that are threatened or at-risk.
  • The Oberlander Prize, a biennial prize in landscape architecture that includes a US$100,000 monetary award and two years of public engagement activities.
