Weeden Foundation: Grants for Marine Conservation

OVERVIEW: The Weeden Foundation supports marine conservation efforts in the United States and abroad.

IP TAKE: This funder’s grants generally go toward the support of specific projects and programs rather than general operating costs.

PROFILE: Frank Weeden established the Weeden Foundation in 1963 and “[e]mbraced the protection of biodiversity as its main priority.” The foundation later expanded its grantmaking interests to address “[p]opulation growth, and over-consumption...in order to more fully address the factors driving biological impoverishment.” Weeden’s current funding programs include Domestic Biodiversity, International Biodiversity, Land Acquisition, Population, and Consumption.

The Weeden Foundation largely awards its marine conservation grants out of its Domestic Biodiversity and International Biodiversity programs. Both grant programs target “[r]iverine/aquatic environments of ecological significance.” The foundation does not typically support general marine conservation issues or basic scientific research. According to the foundation, approximately 30% to 40% of its biodiversity program grants go to support organizations working outside of the United States. Weeden’s current geographical focus areas are the Klamath-Siskiyou Bioregion in Northern California; High Divide in southwest Montana; the Altai Republic in Russia, and Chilean Patagonia. In the past, the foundation has supported projects in “environmentally sensitive” regions of the western United States, Alaska, Russia, Bolivia, Peru, Columbia, Ecuador, Belize, Namibia, Mexico and the Caribbean.

Weeden grants typically range from $10,000 to $25,000 with the average size grant being between $15,000 and $20,000. Past marine conservation grantees include 1% For the Planet and the Smith River Alliance.
