CHEYENNE, Wyo. (AP) — A second coalition of environmental groups is suing the U.S. Fish and Wildlife Service claiming the federal agency violated the Endangered Species Act by ending protections for wolves in Wyoming this fall. The eight groups filed a lawsuit Tuesday in federal court in Denver. They say Wyoming's management plan classifying wolves as predators that can be shot on sight in most of the state is inadequate. Wyoming Gov. Matt Mead has said he's confident the state's plan offers adequate protection for wolves. Tuesday's lawsuit follows a federal suit filed by another coalition earlier this month in Washington, D.C. Both suits seek to force the Fish and Wildlife Service to rescind its transfer of wolf management authority to Wyoming and protect them again under the federal Endangered Species Act.
