CHEYENNE, Wyo. (AP) — Environmental groups have filed notice they intend to sue over a new Wyoming law that could authorize grizzly bear hunting even though grizzlies are federally protected.

The Sierra Club, Center for Biological Diversity, Wyoming Wildlife Advocates and Western Watersheds Project sent the notice Wednesday to Wyoming officials including the director of the Wyoming Game and Fish Department.

Wyoming and Idaho were preparing to hold grizzly bear hunts in 2018 when a federal judge in Montana ruled the bears needed re-listing as a threatened species.

On Friday, Wyoming Gov. Mark Gordon signed a bill that would allow the state Game and Fish Commission to plan a grizzly bear hunt, anyway.

The groups say Wyoming lacks authority to hold a grizzly hunt. Wyoming officials didn't immediately respond to a request for comment.
