Two unknown packs of Mexican wolves discovered.
Instead of a growing population, the number of wild Mexican wolves in Arizona and New Mexico has hung between about 40-60 animals for years now. On top of that the Arizona government for three years now has refused to release any of captive Mexican wolves that have been held in reserve.Now, however, two previously unknown male/female pairs of wild Mexican wolves have been discovered. Technically these might be considered to be packs because they will more than likely produce pups next spring. This last spring 18 pups were born. However, the previous year the pup number was higher than that and yet half of them died or were killed before the end of their first year.
The Mexican wolf was extinct in the wild. That last handful in the wild were captured to put them in a number of breeding facilities to build up a population for re-release in the wild. In the facilities great care is taken to conserve what little genetic diversity exists in the captive population.
