FILE - In this Feb. 10, 2006, file photo, provided by Michigan Technological University, a pack of gray wolves is shown on Isle Royale National Park in northern Michigan. The Michigan Department of Natural Resources issued a report Wednesday, April 23, 2014, that the estimated number of gray wolves in Michigan's Upper Peninsula has declined for the second consecutive year to about 636 following the state’s first wolf hunt in decades. But the agency said the change isn't statistically significant and the resurgent predator is maintaining a healthy presence in the state's far north.
