For years, wolves have been shot illegally, struck by cars and trucks or legally killed by authorities acting on reports that wolves were killing and threatening livestock and pets.

But in a study published Monday in the Journal of Mammalogy, UW researcher Adrian Treves and a group of scientists found higher levels of illegal killing of wolves in Wisconsin than reported by the Department of Natural Resources.

As part of the study, the University of Wisconsin-Madison researchers reinvestigated fatalities of a subset of wolves and found “abundant evidence” of gunshot wounds and injuries from trapping that may have been overlooked as a factor in their deaths, the authors said.
