Since its first publication in 1982, The Wolf in the Southwest has proven itself as the single most valuable and informative reference to Canis lupus of the Mexican borderlands. Now, the descendants of the last wolves captured in Mexico once again roam portions of wilderness in New Mexico and Arizona. This edition contains a new preface by David E. Brown, and a new introduction by author and biologist Harley Shaw. Once again there are wolves in the woods; love him or hate him, the wolf is again relevant, and The Wolf in the Southwest is back in print.
