The Hollis Foundation is a mission-focused environmental funder that concentrates on land protection, restoration, and sustainable agriculture in the Pacific Northwest—especially Oregon. Its portfolio is dominated by repeated, sizable gifts to land trusts, conservation NGOs, and place-based partnerships, with occasional support for park-based K–12 education and local community trust initiatives. The foundation favors organizations that undertake land acquisition, stewardship, and regional conservation network-building rather than one-off program pilots.
A $1,000,000 grant to Oregon Community Foundation in 2025 signals the scale at which Hollis Foundation operates. The foundation’s giving is centered on environmental work in the Pacific Northwest, with repeated support for land trusts, agricultural land protection, habitat restoration, and place-based conservation partnerships. Oregon organizations appear often, but the portfolio also reaches across the region to Washington and Idaho through groups working on land acquisition, stewardship, and restoration. Columbia Land Trust received multiple seven-figure and half-million-dollar awards across 2024 and 2025, showing that Hollis Foundation favors sustained support for conservation organizations with on-the-ground land protection work. Oregon Agricultural Trust also appears repeatedly with large grants, aligning with the foundation’s interest in working lands conservation. Alongside those larger environmental gifts, the foundation has made smaller awards to park-based K–12 education groups, indicating a narrower education-related strand tied to outdoor learning and community access to green space. The overall pattern is a public charity with regional environmental priorities and a clear preference for sizeable grants to established nonprofits rather than many small awards.
Land protection is the clearest theme in Hollis Foundation’s recent giving. Columbia Land Trust received $500,000 in 2024 and again in 2025, both marked for environment-related work. Working lands conservation is another major area. Oregon Agricultural Trust received $500,000 in 2023, $400,000 in 2024, and $350,000 in 2025, indicating repeated support for agricultural land protection over multiple years. The foundation also supports watershed and habitat restoration. Wood River Land Trust Company received $160,750 in 2023 and $155,000 in 2024, while Lomakatsi Restoration Project received $75,000 in 2025 for environment-related work. A smaller but distinct line of giving supports outdoor education and park access. Friends of Tryon Creek State Park received $50,000 in 2025 for K–12 education.
Hollis Foundation’s typical grant size is sizable: the 25th percentile is $93,750, the median is $100,000, and the 75th percentile is $412,500. The recent record shows repeat awards to the same organizations across multiple years, which points to ongoing relationships rather than one-time gifts. It is a public charity and a regular funder, and the grants listed are all program-oriented rather than operating support. No application process is described in the provided data.

Highly concentrated, place-based giving: a small number of large, repeat grants dominate the portfolio. The foundation prefers multi-grant relationships with land trusts, statewide intermediaries, and conservation networks rather than many small, one-time awards.
