An environmental or biodiversity conservation nonprofit seeking project or program support, typically in the $5k–$50k range, with a clear conservation focus and ability to submit a letter of inquiry through the foundation's online system.
Good Fit
- • Mission focused on biodiversity, wildlife, or habitat conservation.
- • Project-level funding requests in the small-to-midsize grant range (many awards $5k–$50k).
- • Willingness to follow a required letter-of-inquiry step and apply via the foundation's online portal.
- • Capacity to demonstrate program impact and alignment with the foundation's stated conservation priorities.

Geography
Observed grants in the latest year went to recipients in 37 states and several international locations, with only about 15% concentrated in the largest state and a small in-state share, indicating a broadly national and limited international footprint.
Recipient Variety
The foundation made 132 grants to 132 distinct recipients in the latest year, funding many independent conservation organizations of different sizes and showing low dollar concentration (top recipient ~3%, top five ~12%).
New Applicants
Direct evidence of openness includes published application guidelines, an online portal, and a requirement that new applicants submit letters of inquiry; behaviorally the foundation added about 66 new recipients in 2024 (roughly half of that year's grantees), supporting plausibility that unfamiliar applicants can enter the portfolio.
