Two more packs of Mexican gray wolves were released into eastern Arizona last week, bringing the number of wolves in the area’s reintroduction program to at least 19. One pack, taken from central New Mexico, was driven into Arizona, flown by helicopter into the Arizona forest, then packed into the backcountry on mules. The reintroduction effort in the Southwest began last year and has met with some trouble; at least five of the first 11 wolves released into the wild have been shot to death.
