What Wilburforce Foundation does

Wilburforce Foundation is a private philanthropic grantmaking foundation founded in 1991 by Rose Letwin and headquartered in Seattle, Washington. The foundation's stated mission is to protect the irreplaceable lands, waters, and wildlife of Western North America, and it is funded solely by its founder rather than through public fundraising. It deploys capital to conservation non-profits operating across 13 priority regions spanning the United States, Canada, and Mexico, organized into three geographic programs (Alaska/British Columbia, Northwest/Southwest, and Yellowstone to Yukon) and supplemented by crosscutting work in conservation science, law and policy, and capacity building.

Its core "products" are grant programs rather than commercial offerings. Grants are awarded via a consultative process with program officers and approved at three annual board meetings, with multiple-year grants reserved for foundation invitation. Notable grantees include Alaska Wilderness League (grantee since 1997), Conservation Northwest, Wildlands Network (including jaguar corridor work along the U.S.-Mexico border), WCS Canada, Colorado Plateau Foundation, Salmon Beyond Borders, and Headwaters Montana. The foundation also runs an annual Conservation Leadership Awards program recognizing leaders in Western North American conservation.

The business and operating model is a sole-funder private foundation. With approximately 12-13 staff led by Executive Director Lisa Weinstein and COO Courtney Price, the foundation has deployed over $217 million in conservation grants since 1991. In 2024-2025, the foundation restructured by phasing out Conservation Science and Conservation Law & Policy as standalone programs and narrowing its Capacity Building program to exclusively support delivery partner TREC, while continuing to hire in grants management. The foundation operates with no external investors, no parent company, and no subsidiaries.

Direct peers

• Resources Legacy Fund: Foundation supporting conservation, environmental justice, and ocean health through grantmaking to NGOs, with strong Western U.S. focus. Comparable as a private foundation making strategic grants to conservation organizations across similar geographies and policy priorities as Wilburforce.
• Patagonia Environmental Grants: Environmental grantmaking program funded by Patagonia (and now Holdfast Collective) that funds grassroots conservation organizations. Highly comparable as a privately-funded, science-informed foundation making grants to land/water/wildlife conservation NGOs in North America.
• Alaska Conservation Foundation: Alaska-focused conservation grantmaker supporting habitat protection, climate, and Indigenous-led conservation. Highly comparable to Wilburforce's Alaska/British Columbia program given overlapping geography, grantee base, and grantmaking approach to conservation nonprofits.
• Turner Foundation: Private foundation founded by Ted Turner supporting environmental and conservation efforts across the U.S. Wilburforce's Executive Director Lisa Weinstein previously served as Senior Program Officer at Turner Foundation, indicating directly overlapping mission, geographies, and operational model as a private, family-controlled environmental grantmaker.
• Yellowstone to Yukon Conservation Initiative: Nonprofit organization working on landscape-scale connectivity from Yellowstone to Yukon — one of Wilburforce's namesake program areas and geographic priorities. Directly comparable as a conservation organization that both funds and operates initiatives across the same Western North American geography.

Broad incumbents

• The Pew Charitable Trusts: Major philanthropic organization with substantial U.S. conservation grantmaking covering Western lands, marine habitat, and species protection. Overlaps with Wilburforce on Western landscape conservation and science-based policy approach, though Pew operates at much greater scale and across multiple program areas.
• David and Lucile Packard Foundation: Large private foundation with significant marine and land conservation grantmaking, including in Western North America. Comparable as a high-capacity, science-informed family foundation funding landscape conservation, with overlap on multi-year grants and capacity-building approach.
• William and Flora Hewlett Foundation: Large foundation funding environmental initiatives including U.S. West and climate policy. Comparable as a foundation with both Western landscape and broader conservation/climate funding, though operating at significantly greater scale across multiple program areas.
• Gordon and Betty Moore Foundation: Large private foundation with major environmental/conservation grantmaking, including Western landscapes and Andes-Amazon work. Comparable as a founder-funded, science-driven foundation deploying patient capital to conservation, though operating across a far broader portfolio (science, patient care) than Wilburforce.

Emerging players

• Campion Advocacy Fund: Philanthropic fund supporting public lands advocacy and conservation policy. Comparable given that Wilburforce's Program Director John Daly previously led Campion's public lands program, and both organizations overlap on Western U.S. lands protection, policy advocacy, and conservation grantmaking.
