The Weeden Foundation shows a highly concentrated giving pattern: in the reported period it made one large, unrestricted grant ($1.85M) described only as “See Attached Schedule” for general purpose support. This suggests the foundation channels substantial, flexible funding through an intermediary or distributes it across multiple unnamed beneficiaries rather than making many small, mission-restricted gifts. With no explicit NTEE coding or grantee names provided, the foundation appears to prioritize large-scale, discretionary grantmaking over narrow program-specific awards.
A $1.85 million general-purpose grant in the 2023 schedule is the clearest signal in Weeden Foundation’s recent record: it makes concentrated, flexible gifts rather than a wide spray of small awards. The foundation’s 2025 filing also shows a cluster of environmental grants around $25,000 to $52,000, with support reaching groups working on wildlife, forests, rivers, and large-landscape conservation. That combination points to a funder that backs conservation through both one large unrestricted distribution and a series of narrower mission-aligned grants. In the recent grants list, Resolve received $52,000, and the National Wildlife Federation received $50,000. Other 2025 awards went to organizations such as the Center for Biological Diversity, Pacific Forest Trust, and Western Rivers Conservancy, which places the foundation’s activity squarely in environmental and conservation philanthropy. The presence of an attached schedule grant alongside named program grants suggests a mix of aggregated support and direct grants. For researchers, Weeden Foundation reads as a locally focused private foundation with a strong preference for substantial grants and environmental beneficiaries.
Weeden Foundation’s 2025 grants cluster around conservation, species protection, and land and water advocacy. The Center for Biological Diversity received $50,000, while the Pacific Forest Trust received $42,000, showing support for groups engaged in biodiversity and forest protection. The National Wildlife Federation’s $50,000 grant fits the same pattern of wildlife-oriented funding. The foundation also backed landscape and river work. It gave $30,000 to the Center for Large Landscape Conservation and $25,000 to Western Rivers Conservancy, both of which point to habitat-scale and watershed conservation. Internationally, Puelo Patagonia received $40,000 and Valdivia Legal received $25,000, indicating that part of the portfolio extends beyond the United States into South American conservation efforts. Together, these grants show a consistent environmental agenda across species, forests, rivers, and place-based conservation.
The reported grant-size distribution is fully concentrated at $1,846,227 for the 25th percentile, median, and 75th percentile, reflecting an unusually uniform size profile in the available data. One 2023 general-purpose grant accounts for the large end of that pattern, while the 2025 list shows smaller, direct awards layered underneath it. The funding model appears to combine a pass-through or schedule-based distribution with named grants. The recipient list includes organizations that appear in the 2025 file, but the dataset does not show repeated awards to the same grantees across multiple years. Weeden Foundation does not fund individuals and does not make program-related investments. The grant descriptions identify at least one award as “General Purpose Grants,” which points to flexible support rather than tightly restricted project funding.

Highly concentrated: a single, large general-purpose grant (likely pass-through to multiple beneficiaries). Prefers sizable, flexible funding rather than numerous small or earmarked grants; limited public detail about end recipients.
Notable grantees: See Attached Schedule (aggregate/undisclosed beneficiaries)
Grant recipients are heavily concentrated in the United States, which accounts for 119 grants, or 89.5% of the recipient-country distribution. Within the named recent grants, Washington, DC; Missoula, MT; Tucson, AZ; San Francisco, CA; Bozeman, MT; and New York, NY all appear multiple times, showing a strong U.S. spread across conservation hubs. The foundation’s giving is marked local in scope, but the recipient mix also includes international organizations in Puerto Varas, Futaleufu, Santiago, Vancouver, London, and Belmont, MA.
The recent grants show a strong environmental and conservation focus. Named recipients include the National Wildlife Federation, Center for Biological Diversity, Pacific Forest Trust, Western Rivers Conservancy, and American Bird Conservancy, alongside groups working on forests, rivers, wildlife, and large-landscape conservation.
The grant-size data is extremely concentrated: the 25th percentile, median, and 75th percentile are all $1,846,227. That indicates the available dataset reflects a single large grant size rather than a broad spread of award amounts.
The recent-grants file shows a mix of a large 2023 general-purpose grant and multiple 2025 named grants. The data does not show the same recipient appearing in multiple years, so the visible pattern is a set of discrete awards rather than clearly repeated multi-year grants to the same organizations.
Its recipient-country distribution is dominated by the United States, with 119 grants, or 89.5%. The named recent grantees are mostly U.S.-based, but the list also includes organizations in Puerto Varas, Futaleufu, Santiago, Vancouver, and London.
The foundation does not fund individuals and does not make program-related investments. The data includes a $1.846 million grant described as “General Purpose Grants,” which suggests flexible support, and the summary indicates the foundation may use an attached schedule or intermediary-style distribution for part of its grantmaking.
