Mexican Gray Wolf — Canis lupus baileyi, el lobo

Status: Researched draft — cultural review pending

• Entry kind: a recovery entry, not an extinction entry — this register's one species line: a species deliberately exterminated by a state, and deliberately returned, with an Indigenous nation as a governing partner in the return
• Standing, in one line: extinct in the wild (United States by c. 1970; Mexico by 1980) — returned (1998 / 2011)
• Range: the montane woodlands and Sierra Madre Occidental of Arizona, New Mexico and west Texas, and northern and central Mexico

How to read this entry. Documented fact = agency, programme, or published record (sources named, with the year on every count). Tradition — a people's own account = published testimony of the White Mountain Apache Tribe, labelled as such and quoted under its speakers' names. Debated / Claim = a disputed point, held open. Counts are minimum counts, dated by count-year, as the field teams publish them — minimums, not censuses, and never merged across authorities.

THE ANIMAL AND ITS PLACE

The Mexican wolf is the smallest and most genetically distinct North American gray wolf subspecies. In the peoples' worlds it stands at published testimony — Documented as testimony: for the White Mountain Apache Tribe the wolf is ba'cho; tribal cultural director Ramon Riley holds an unwritten wolf song, learned from elders, sung to summon the wolf's power before battle, which “does not translate into English”; tribal biologist Krista Beazley records elders' teaching that warriors imitated the wolf's travelling and hunting; and tribal member testimony, given publicly: “The Apache People respect every creature on the land; the mighty Creator has them here for a purpose. That's why we want to bring the Mexican wolf back to its home, which is White Mountain Apache land.” The Tribe — 1.6 million acres, the Fort Apache Reservation, adjoining the Blue Range — has been a formal recovery partner for some fifteen years (USFWS congressional testimony, 2016).

Tradition at its class: the wolf song itself is oral tradition, held, not published; this entry prints only that it exists and who holds it. No White Mountain Apache knowledge page stands in this encyclopedia's knowledge doorway — that page is OWED, flagged here rather than the people folded into a species entry; the testimony above stands quoted and attributed in the meantime.

THE ERADICATION — DOCUMENTED

• Bounties first: territorial and state bounties from the 1890s (Arizona–New Mexico Territorial Bounty Act, 1893).
• Then the federal programme: the Predatory Animal and Rodent Control service (PARC), organised 1915 within the US Bureau of Biological Survey, made wolf extermination its programme — salaried hunters using steel leghold traps, denning (killing pups in the den), shooting, and poison: strychnine and arsenic baits, later sodium cyanide “coyote getters” and Compound 1080. PARC's own reporting counted over 900 Mexican wolves killed in Arizona and New Mexico by government trappers and cooperators in 1915–1925 alone; a greater bounty kill in 1890–1915 is believed but not documented to a figure.
• The programme exported: from 1950 the US Fish and Wildlife Service exported it into Mexico — salaried personnel and US-made poison.
• The end in the wild: the last verified wolf caught crossing from Mexico was shot in 1960; the subspecies was extirpated in the wild in the United States by about 1970 (USFWS recovery-coordinator record; other Service summaries say “by the mid-1900s” — the range 1950s–1970 is printed, not a single year).

THE LAST WILD WOLVES AND THE SEVEN FOUNDERS — DOCUMENTED

Roy T. McBride, a professional trapper contracted by USFWS, live-trapped five wolves in Durango/Chihuahua country, Mexico, between 1977 and 1980 — four males and one pregnant female. Those five form the certified McBride lineage, counting three founders (one male was the female's offspring). Two older captive lineages — Ghost Ranch and Aragón (Mexico City zoo stock) — added two founders each when the three lines were certified and merged in 1995. Total: seven founders for every Mexican wolf alive today. No wild wolf has been confirmed in Mexico after the last capture in 1980. (USFWS 5-Year Evaluation, December 2024; Species Survival Plan record.)

LISTING AND PROGRAMME — DOCUMENTED, WITH A CORRECTION CARRIED ON THE FACE

• The Mexican wolf was listed as an endangered subspecies in 1976 (41 FR 17740); in 1978 that listing was subsumed into the general gray wolf listing; it was listed again as a separate endangered subspecies in January 2015 (80 FR 2488). The “ESA listing 1978” shorthand in the teaching's circulation is therefore corrected here, not repeated.
• The binational captive-breeding programme (Mexican Wolf Species Survival Plan, US–Mexico, from 1977–80) and the first Recovery Plan (1982) followed; the captive population now stands at roughly 350–380 animals in more than 60 facilities in both countries (figures range by year and source — printed as a range).

THE RETURN — DOCUMENTED

• United States: on 29 March 1998, 11 wolves were released into the Apache National Forest, Blue Range Wolf Recovery Area, eastern Arizona, as a nonessential experimental population under ESA §10(j), management shared with Arizona, New Mexico and the White Mountain Apache Tribe.
• Mexico: releases began 11 October 2011 (five wolves, Sierra de San Luis, Sonora) into the Sierra Madre Occidental (Chihuahua, Sonora, later Durango); Mexico reclassified the wolf nationally from “probably extinct in the wild” to “endangered” in 2019, after wild-born litters were documented from 2014.

THE COUNTS — DATED MINIMUM COUNTS

Two limits stand on the face. Recovery criteria and downlisting thresholds (a four-year US average of 320) are agency policy, Debated in litigation and in the scientific literature. And genetic health is Debated: mean kinship in the wild US population in 2025 (0.2404) approaches that of full siblings (0.25) — the direct legacy of the seven founders.
