BOISE, Idaho (AP) — A hunting derby with $1,000 each for whoever kills the most wolves and coyotes is scheduled to start at sunrise Friday in east-central Idaho.

Idaho for Wildlife's three-day Predator Hunting Contest and Fur Rendezvous is planned on private ranch land and U.S. Forest Service land around Salmon. The U.S. Bureau of Land Management in November withdrew a permit it had issued to the group following lawsuits by environmental groups.

Derby organizer Steve Alder says hunters will likely use BLM land anyway but animals killed there won't be eligible for contest prizes. The event last year drew 230 people, about 100 of them hunters, who killed 21 coyotes but no wolves. Environmental groups say they will make another attempt in 2015 to stop the derby.
