The use of dog shock collars on two different gray wolves (Canis lupus) were examined over a 4-year period to assess whether this system could be used to reduce wolf depredation on livestock. Results indicated that in some situations shock collars with a command center and beeper device could be useful for reducing wolf depredations.

Wolves that are recolonizing mixed agriculture and forest areas in the Lake Superior region are increasingly preying on livestock, generating public complaints and demands for compensation. Researchers documented the number of complaints about wolves in Wisconsin from 1976 to 2000 and analyzed the patterns surrounding the incidents to generate data to help prevent wolf depredation and create a foundation for policy-making related to the planned federal delisting of the wolf.

A new study examines the potential for wolf recovery in the northeastern US and determines whether it could be achieved naturally via dispersal from southeast Canada or through managed reintroduction. Biological factors considered include dispersal habitat, habitat conditions and distance to source populations. It is shown that recovery is a possibility, although there are serious limitations, including negative human attitudes towards predators.

The impact of breeder loss on wolves' survival, reproduction and territorial social groups is examined. To minimize negative impacts, the managers of recolonizing wolf populations should limit lethal control to solitary individuals or territorial pairs where possible, as the selective removal of pack members can become very difficult.
