Funders are ordered by how much of their overall giving goes to environment & conservation work in Maine, not by dollar totals alone — a foundation that concentrates its giving here is usually a better prospect than a larger one for which this is a rounding error. 18 of the funders counted here are donor-advised fund sponsors, which grant on behalf of individual donors and accept no applications; they are marked and ranked last.

About This Data

A grant appears here when a funder reported it on its IRS Form 990 and the recipient organization is classified under the NTEE group covering environment & conservation work, with an address in Maine. Grants are counted from the 2025 filing year backward.

Some 990 grant schedules list a recipient by name and address without an EIN, and those grants cannot be matched to a classification — so the totals above represent identifiable environment & conservation funding in Maine, not every dollar that reached the sector. Figures are a floor, not a ceiling.
