Two conservation groups say a federal plan to bolster threatened populations of bull trout in five Western states falls short, and they’ve filed notice of their intention to sue, the AP reports. Alliance for the Rockies and Friends of the Wild Swan said the plan violates the Endangered Species Act. "They essentially want to redefine recovery to almost extinct," said Mike Garrity, executive director of Alliance for the Wild Rockies. "They're lowering the bar so they can delist bull trout." The U.S. Fish & Wildlife Service had no comment; you can read a full report here from AP reporter Keith Ridler.
