    About Paul Simons Foundation

    The Paul Simons Foundation is a highly focused environmental funder that dedicates its entire reported grantmaking to land conservation, supporting a single beneficiary. All recorded giving funds Avalon Nature Preserve, indicating a strong commitment to protecting and stewarding a specific natural area—likely in the foundation's local region (Long Island/Stony Brook). The foundation appears intent on long‑term preservation through large, concentrated gifts rather than broad-based grantmaking.

    Focus Areas

    Land conservation and preservation (private nature preserve/land trust)Habitat protection and ecological stewardship of local/regionally significant open spaceSupport for nonprofit landowners/land trusts managing protected properties

    Who They Fund

    fellows (program participants)nonprofit organizations (grantee organizations)

    Giving Approach

    Highly concentrated: very large, repeat grants to a single grantee (Avalon Nature Preserve), indicating multi‑year or capital support for land acquisition, endowment, or major stewardship projects rather than diversified or small grants.
