Thirty conservation organizations have urged wildlife agencies to take science-based actions to protect Mexican gray wolves after a new analysis showed a declined in the endangered species’ genetic diversity for the 4th year in a row. In a letter to the U.S. Fish and Wildlife Service, Arizona Game and Fish Department and New Mexico Department of Game and Fish, the groups requested that government agencies release wolf families because the captive population has 37% more genetic diversity than the wild population. They also asked state and federal officials to stop removing genetically valuable wolves from the wild and allow Mexican gray wolves to mate with northern gray wolves, as they did for millennia. “Mexican wolves won’t recover unless agencies restore as much genetic diversity as can be salvaged from what’s already been squandered,” said Michael Robinson, a senior conservation advocate at the Center for Biological Diversity. “Federal and state agencies need to stop killing wol...
