Ideal Applicant
Organizations working in environmental conservation, Indigenous-led land/forest protection, or related education and community resilience projects with demonstrated impact and credibility; applicants can be U.S.-based or operating internationally in ecological/Indigenous contexts.
Good Fit
- • Work clearly focused on forest, biodiversity, or Indigenous land protection and stewardship.
- • Requests for general operating or program support tied to ecological regeneration or Indigenous-led initiatives.
- • Demonstrated partnerships, regional leadership, or prior impact in conservation/Indigenous sectors.
- • A national or international scope (the foundation funds across many states and some international projects).
- • Track record or introductions through known movement intermediaries, fiscal sponsors, or peer organizations.
Geography
Observed giving in the latest year reached 22 distinct states, with most dollars sent out of the foundation's state and meaningful shares in California and New York, indicating a national (and some international) footprint.
Recipient Variety
The latest year shows 64 distinct grantees across many mission areas related to environment and Indigenous work; the portfolio includes many independent organizations rather than a tiny closed circle, and the top five recipients account for under a third of dollars.
New Applicants
Direct evidence of turnover exists—29 new grantees in 2023—so new entrants have been added, but the public materials state the funder makes grants by preselection rather than an open application, so unsolicited access looks possible but curated rather than straightforward.
