Three measures, three different questions

The Puerto Rican Paso Fino is listed as Threatened on The Livestock Conservancy’s 2026 Conservation Priority List. Threatened is a priority category under that organization’s criteria; it is not an IUCN assessment and it is not itself a count of living horses. The category signals that population monitoring and continued conservation breeding matter, but it cannot tell a reader how many horses are alive on a particular date.

The Conservancy’s breed profile, updated August 20, 2025, gives two additional statements: fewer than 500 Puerto Rican Paso Finos are registered in the United States, and fewer than 2,500 can be found globally. The first is registry-bounded and geographically limited. The second is a broader global estimate. Because the definitions and scopes differ, subtracting one from the other would not produce a defensible Puerto Rico total.

A registration record is also not automatically a living-animal census. Registries preserve identity and pedigree across time, so their historical records may include horses that are no longer alive. A living-population estimate needs a stated census date, a way to identify current status, and rules for avoiding duplicates. Annual registrations answer yet another question: how many new records were created in a year, not how many horses survive.

Registry infrastructure still matters. A 2022–23 Livestock Conservancy microgrant announcement described an upgrade for the Pure Puerto Rican Paso Fino Federation of America’s pedigree-search and hypothetical-mating tools, with services intended to expand to Puerto Rico. That announcement documents a records project, not a population count. It shows why preservation requires both reliable source records and careful interpretation.

Conservation Legacy’s working method keeps four layers separate: the original registry or association record; a canonical horse identity when duplicate records can be reconciled; a likely-living status supported by dated evidence; and a verified-living status confirmed through an authorized current source. Private owner, farm and horse details remain private unless permission is granted. Aggregate teaching should report its date, geography, inclusion rules and uncertainty rather than exposing individual records.
