Conservation groups sue over status of black-footed ferrets

A trio of conservation groups sued the U.S. Fish and Wildlife Service on Thursday over its management of black-footed ferrets in Wyoming. Even though the black-footed ferret, North America’s only native ferret species, is still classified as endangered, the agency delegated responsibility for the species to the state in 2015. The federal lawsuit criticizes the rule and calls for oversight to be returned to the federal government.
