Illinois preps for possibility of wolf population

CHICAGO — The wolf was believed to be a lone male expelled by a pack in Wisconsin. The hunter who shot him in northwestern Illinois, allegedly keeping his skull as a trophy, was the first person in the state ever prosecuted for shooting a wolf under federal endangered species laws.

The incident, resolved in 2013 when the hunter pleaded guilty and paid a $2,500 fine, comes amid evidence of a modest but perceptible uptick in the number of wolves roaming across the Wisconsin border into heavily populated and widely farmed Illinois.
