Environmental groups filed lawsuits Tuesday in Idaho and Washington, D.C., seeking to force federal officials to reveal reasons behind allowing a wolf- and coyote-shooting contest in parts of Idaho, the AP reports. The lawsuits contend the U.S. Bureau of Land Management is violating the Freedom of Information Act by withholding records sought by the Center for Biological Diversity and Western Watersheds Project.

Steve Alder of Idaho for Wildlife said the group isn't holding its Predator Hunting Contest this winter because hunters were unable to kill any wolves the previous two winters. "We don't care about lawsuits, but we failed miserably at harvesting a wolf," Alder said. "There's no point getting sponsorships and doing this and that and not being able to get a wolf."

The group overcame lawsuits to hold the events on private land and U.S. Forest Service land the past two winters. The contest last year offered a $1,000 prize each for whoever killed the most wolves and coyotes. About 100 hunters killed 30 coyotes but no wolves.
