PREDATORS -- Conservation groups announced today that they are suing federal and state officials over Idaho’s plan to track and kill wolves from two packs in the Frank Church-River of No Return Wilderness.

The lawsuit, filed by Defenders of Wildlife, Western Watersheds Project and Wilderness Watch in Pocatello’s U.S. District Court on Monday, asks the judge to stop the plan immediately to give the case time to work through the courts. The environmental groups are joined by Ralph Maughan, a former Idaho State University professor, conservationist and long-time wolf recovery advocate from Pocatello.
