Ideal Applicant

A qualified 501(c)(3) organization working in Philadelphia or its suburbs on animal welfare, wildlife rehabilitation, or land/ habitat conservation with a clear program budget and recent fiscals.

Good Fit

  • Primary programs focused on animal welfare, wildlife rehabilitation, or land conservation serving the Philadelphia metro area or suburbs.
  • Ability to provide a short application letter plus EIN and recent revenue/expense figures.
  • Organizational scale and projects consistent with past grants (range from small operating grants up to multi-hundred-thousand dollar habitat grants).
  • Local presence or demonstrable substantial work in Philadelphia or surrounding communities.

Geography

Moderate

Observed grants span three states (PA, DE, NJ) but are heavily focused on Pennsylvania, with 63% of dollars directed to PA and an explicit preference for Philadelphia and its suburbs.

Recipient Variety

Broad

The latest year funded 29 distinct recipients and the foundation funded many independent organizations across two observed years (21 returning recipients and 8 new recipients), indicating a broad recipient set despite dollar concentration in a few large grants.

New Applicants

Broad

There is an explicit public application route (short letter with required documents) and the latest year included eight new grantees; based on these behaviors and visible instructions, unfamiliar eligible organizations with the right local/mission fit appear reasonably likely to be considered.
