CHEYENNE, Wyo. (AP) - After more than a decade of federal protection, gray wolves will be fair game for hunters and ranchers in most of Wyoming when the animals are removed from the endangered species list on Friday.

Wyoming, Montana and Idaho will take over full management of the wolves, while the U.S. Fish and Wildlife Service is ending its wolf recovery effort.

In northwestern Wyoming, the state will continue a federal policy allowing ranchers to kill on sight wolves caught in the act of attacking their livestock or domestic animals. In the rest of Wyoming, the rules will allow people to kill wolves at any time and for any reason.

In Idaho, wildlife officials say no immediate changes would occur with delisting.

At least seven environmental groups say they intend sue the federal government next month to stop the delisting process.
