Ideal Applicant
Established charitable organizations working in environmental conservation, land/trail projects, community services, or select health/youth programs with programs sized to match typical grant amounts (several thousand to tens of thousands).
Good Fit
- • Programmatic alignment with environmental conservation, active transportation, land protection, or related community development.
- • Presence or operations in states the foundation frequently funds (notably New York, Massachusetts, New Jersey).
- • Project budgets and past grants sized in the foundation's observed range (roughly $2.5k–$55k).
- • Existing relationship, introduction, or visible collaboration with organizations already in the foundation's network.
Geography
Grants are distributed across many states (about 17 distinct states in the latest year) with the majority of dollars going outside the foundation's home state and a top state receiving roughly 25% of dollars.
Recipient Variety
The latest year shows a large number of distinct recipients (119) spanning conservation groups, universities, and health/community organizations; while many grantees are returning, a substantial number of independent organizations are funded each year.
New Applicants
Observed behavior shows meaningful turnover and new grantees (36 new recipients in the latest year), indicating unfamiliar organizations have been funded; however, the foundation states it only funds preselected applicants and offers no public application route, so unsolicited access appears limited.
