A study of deer-vehicle collisions in Wisconsin found that, on average, wolf introduction reduced deer-vehicle collisions by 24% in counties, and that the economic benefit from collision reduction was 63 times greater than the verified economic harm of wolf predation of livestock; the study further found that collision reduction was attributable to changes in deer behavior to a greater extent than to changes in deer population, suggesting that hunters cannot replicate all of predators' effects on prey populations.
