Weeden Foundation

BEDFORD HILLS, NY EIN: 94-6109313 Website

The Weeden Foundation is a private grantmaking foundation established in 1964 and headquartered in Bedford Hills, New York. The Foundation was created by Frank Weeden to address the impact of growing human populations and overuse of natural resources on the biological fabric of the planet. Since its founding, the Foundation has been instrumental in global conservation efforts, having helped preserve more than 6 million acres of biologically important habitat worldwide and providing financing for the first debt-for-nature swap in Bolivia in 1992—a strategy now widely adopted by international conservation organizations.
