Ideal Applicant
A U.S.-based environmental or marine conservation organization running measurable coastal or restoration projects (coral, mangrove, tree planting, plastic cleanups) with capacity to manage mid-sized grants and demonstrated outcomes.
Good Fit
- • Project focus on coral reef, mangrove, tree planting, or plastic/ocean cleanup.
- • Operational presence or partnerships in California or other U.S. coastal states.
- • Project budgets and capacity roughly in the observed grant range (~$10K–$280K).
- • Evidence of measurable restoration outcomes and clear use of funds.
- • Willingness to engage in partnership or campaign-aligned work rather than purely unrestricted support.
Geography
Grants in 2024 went to organizations in four states (CA, NY, VT, FL), with a strong concentration of dollars to California (about 69%), showing a multi-state footprint rather than a single-county focus.
Recipient Variety
The latest year shows seven distinct recipients and four new entrants, and three recurring recipients across the three-year record; dollar concentration is high (top five received 91%), so institutional variety exists but funding is financially concentrated.
New Applicants
Behavior shows new grantees entering the portfolio (four new recipients in 2024) and a public website with contact emails, but no formal application instructions were found, so new entrants are plausible though not clearly enabled by a public grantmaking process.
