What We Fund

For its 40 years of existence, the Weeden Foundation’s primary mission has been to protect biodiversity. It has helped preserve more than 6 million acres of biologically important habitat worldwide. The Foundation financed the first debt-for-nature swap in Bolivia in 1992, a strategy that is now widely used by international conservation organizations.

Currently, the Foundation has four geographical focus areas:

1) Klamath-Siskiyou Bioregion in Northern California

2) High Divide in SW Montana

3) Altai Republic in Russia

4) Chilean Patagonia
