Eleven conservation groups have notified the U.S. Fish and Wildlife Service that it violated the Endangered Species Act by removing gray wolves from the endangered species list.
The groups contend that populations in the Northern Rockies do not have adequate genetic diversity, and that the states of Idaho, Wyoming and Montana have not made meaningful commitments to wolf conservation.
The groups, which include Hailey-based Western Watersheds Project, intend to challenge the agency's decision in federal court, they indicated in a Feb. 27 press release.
In an effort to overturn the service's delisting rule before hundreds of wolves can be killed in the three states, the conservation groups served the letter within hours of publication of the delisting rule for gray wolves in the Federal Register.
Under the delisting rule, the states will assume management of wolves on March 28.
