ï» ALBUQUERQUE, N.M. (AP) — A plan by Mexican wildlife officials to reintroduce a rare species of gray wolf to its historic range in northern Mexico has prompted questions from wildlife managers and ranchers in the Southwest, where a similar, decade-long effort has been fraught with controversy.

KRQE-TV and the Carlsbad Current-Argus are reporting that the Living Desert Zoo has flown a Mexican gray wolf to Mexico in hopes of successfully breeding pups to help the embattled reintroduction program.

An Associated Press report reveals that researchers found evidence that ancient Mexicans crossbred wolves and dogs.

Jess Edberg, from the International Wolf Center, wrote an article about Mexico’s plans to reintroduce five wolves following a devastating year where America’s population declined by 20 percent.
