Mission and programs · 2025
Mission
Our mission is to preserve the ancestral genetics within the Carter Reservoir wild horse herd by DNA testing, documenting and recording them, with a goal of working with the Bureau of Land Management (BLM) to maintain the wild herd at healthy sustainable numbers, to educate the public, and to guide the public to view the Carter Reservoir herd without compromising public or horse safety. Study, research and record the Carter Reservoir Herd Management Area (HMA) Mustangs, building a historical foundation. Genetically test the Carter Reservoir Mustangs to continue building upon their proven Spanish-Iberian lineage. Inform the public on the value of the irreplaceable Carter Mustangs among America's wild horse herds. Develop the Carter Conservation Center (CCC) as a holding, placement, and sanctuary facility in preparation for future Carter Reservoir HMA roundups by the BLM. Offer assistance with captive and adopted Carter Reservoir Mustangs. Proactively pursue conservation of a genetically

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.

Grants made
No itemized grants to organizations. Schedule I is filed only by organizations that granted more than $5,000 to a recipient, so most filers have none.

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.
