Other organizations at this address

1 other organization in the IRS Business Master File lists the same street address. matched by us

This address is a suite or unit (STE 303). Organizations that share one are often clients of the same office-services firm, accountant or registered agent rather than related to each other.

We match the street line and ZIP code as the IRS gives them, ignoring case and outer spaces and nothing else, so "AVE" and "AVENUE" count as different streets and this list can miss some. A shared address can mean related organizations or a shared office, but it can also be a registered agent, a mail drop or a service provider holding mail for unrelated clients. It is not, by itself, evidence that two organizations are connected.

Mission and programs · 2024

Mission

Through collaboration of land conservation and forestry organizations MMC innovates and accelerates land conservation in the 5 million-acre Maine Appalachian Mountain Corridor.

Activities or mission (Part I)

Land conservation and stewardship

  • Provided $110,000 in Transaction Fund grants to five land conservation projects in Maine's Northern Appalachian Mountain Corridor that will permanently conserve 52,000 acres of ecologically valuable undeveloped forest. Launched the Exemplary Forestry Investment Fund an impact-first timber investment fund meant to blend impact investment and tangible environmental outcomes for Maine's forests. The first property-specific fund, Scammon Ridge Headwaters LLC, purchased and conserved 3,000 acres in Greenville Maine near Moosehead Lake for sustainable forestry, public access, and improved wildlife habitat. Convened the eleven Maine Mountain Collaborative member organizations to share information about emerging conservation projects, common challenges, and emerging opportunities. This level of collaboration has led to new conservation projects that may not otherwise have been possible. Served on the Conservation Delegation to the Wabanaki Commission on Land and Stewardship to provide coordination and collaboration between Wabanaki Nations in Maine and the conservation community.

Compensation is as filed in Part VII: reportable pay from this organization and from related organizations, other compensation, and hours per week. The total, marked calculated, is our sum of the three dollar columns, with a blank column counted as $0; the form itself has no total. On a Form 990-EZ the columns are Part IV's instead, and on a Form 990-PF Part VIII's — compensation, contributions to benefit plans, and expense account — and the total sums those. Earlier years are each on their own filing page.

Nonprofiteer parses Forms 990, 990-EZ and 990-PF, in a window of recent tax years. These returns are recorded from the IRS e-file index, so their figures were extracted by that index rather than read from the return here — treat them as a different source from the filings above, not as more of the same record. A dash means the index carries no figure; Form 990-T listings carry none at all.

Other IRS files

Auto-Revocation List

Not listed. The IRS publishes this list for organizations whose exemption was automatically revoked for failing to file for three consecutive years.

Publication 78

Listed as of 13 October 2026, under deductibility PC.

These are two separate IRS files on two separate schedules, shown as published and not reconciled with each other. Neither is a statement about whether a contribution is deductible today: 19,245 organizations appear in Publication 78 while the IRS's own revocation file lists them as currently revoked, more than half of those revoked before 2019. Absence from Publication 78 is evidence of nothing, and presence is not evidence either. Verify current status with the IRS before relying on it.
