In 1997, controversy arose when a captive pack at [[Carlsbad Caverns National Park]] designated for release was found by Roy McBride, who had captured many wolves for the recovery programme in the 1970s, to be largely composed of [[wolf-dog hybrid]]s. Though staff initially argued that the animal's odd appearance was due to captivity and diet, it was later decided to euthanise them.<ref>[http://wolfcrossing.org/blog/wp-content/uploads/2007/10/the-courts-were-wrong-these-wolves-are-hybrids.pdf Letter from Roy McBride to David Parsons]</ref> |

In March 1998, the [[United States Fish and Wildlife Service]] (USFWS) began reintroducing Mexican Wolves into the Blue Range area of Arizona. The overall objective of this program was to reestablish 100 Mexican Wolves in the [[Apache-Sitgreaves National Forest|Apache]] and [[Gila National Forest]]s of Arizona and New Mexico by 2008. |

On March 30, 1998, government biologists released 11 gray wolves — 3 adult males, 3 adult females, 3 female pups and yearlings and 2 male pups — from 3 chain-link acclimation pens within the {{convert|18130|km2|sqmi}}, federally designated Blue Range Wolf Recovery Area in east-central Arizona. |

A population count completed by the Interagency Field Team (IFT) in the winter of 2006–2007 estimated 60 wolves living in the recovery area in several packs.<ref>USFWS [http://www.fws.gov/home/feature/2007/gray_wolf_factsheet-region2.pdf ''Wolf Recovery in North America''(2007)]</ref> |

The Mexican Wolf (Canis lupus baileyi) is a subspecies of the Gray Wolf. It is native to North America, where it is the rarest and most genetically distinct subspecies.
Physical features
The Mexican Wolf is the smallest Gray Wolf subspecies present in North America. Reaching an overall length no greater than 1.2–1.5 metres (3.9–4.9 ft) and a maximum height of about 80 centimetres (31 in), it is around the size of a German Shepherd Dog. Weight ranges from 27–37 kilograms (60–82 lb). In stature, it resembles some European wolves, though its head is usually broader, its neck thicker, its ears longer and its tail shorter.Cite error: The <ref> tag has too many names (see the help page).
Former range and extirpation
Until recent times, the Mexican Wolf ranged the Sonoran and Chihuahuan Deserts from central Mexico to western Texas, southern New Mexico, and central Arizona. By the turn of the 20th century, reduction of natural prey like deer and elk caused many wolves to begin attacking domestic livestock, which led to intensive efforts by government agencies and individuals to eradicate the Mexican Wolf. Hunters also hunted down the wolf because it killed deer. Trappers and private trappers have also helped in the eradication of the Mexican Wolf. (Note that recent studies completed by genetics experts show evidence of Mexican Wolves ranging as far north as Colorado). These efforts were very successful, and by the 1950s, the Mexican Wolf had been eliminated from the wild. In 1976, the Mexican Wolf was declared an endangered subspecies and has remained so ever since. Today, an estimated 300 Mexican Wolves survive in 49 facilities at the United States and Mexico.[1]

Captive Breeding Programs
There are 47 Mexican Wolf breeding facilities in United States and Mexico with the largest in the world being the Wild Canid Survival and Research Center near Eureka, Missouri which was founded in 1971 by naturalist Marlin Perkins and his wife Carol. [1] [2]
