The lesser prairie chicken has been placed on the Endangered Species list despite efforts from livestock groups to block the designation.
The bird was added Monday by the U.S. Fish and Wildlife Service, but several groups including the National Cattlemen’s Beef Association and Kansas Livestock Association are suing the agency in a Texas federal court.
Under the listing, the rule requires livestock producers in areas of five states to create grazing plans to protect themselves from activities that could harm the birds.
