Mexican gray wolf

Some ecologists and activists argue the endangered Mexican gray wolf should be reintroduced further north in Arizona to increase the population. But a new study coauthored by the Arizona Game and Fish Department says expanding the range would harm recovery efforts. KNAU’s Melissa Sevigny reports.

Twenty five environmental groups are calling on federal wildlife officials to release three captive-raised Mexican gray wolf packs into the wild. KNAU’s Ryan Heinsius reports, they say the endangered population needs increased genetic diversity to survive.
