During recent years 15 of 25 radio-collared wolves that died were killed by humans. Other diseases include Canine Distemper, Lyme Disease, Mange, and various parasites such as Heartworm and Coccidiosis. Fines and a possible prison sentence await anyone convicted of killing a wolf. About 40-45 wolves exist in Wisconsin in 1992 and the population is increasing. Wolves were portrayed as vile, demented, immoral beasts that often issued pacts with the Devil.
Wolves are controversial because they are large predators.
Farmers are concerned about wolves preying on their livestock. Since 1976, when wolves returned to northern Wisconsin, verified cases of wolf depredation occurred about every other year. As the population continues to increase, slight increases in depredation are likely to occur. A few hunters continue to kill wolves, believing that such actions will help the deer herd. It is important to place in perspective the impact of wolves feeding on deer.
