From WUWM in Milwaukee:
The presence of gray wolves in Wisconsin is considered a success story. The wolf is native to the Great Lakes and other parts of the U.S., but by the 1950s, the population was teetering on extinction. The gray wolf was placed on the federal endangered species list in 1975. By 2012, its numbers had rebounded and the gray wolf was taken off the list.
Soon after, Wisconsin legislators passed a bill that mandates an annual wolf harvest season and the controversial use of dogs. Three annual hunts followed until a federal judge put the wolf back on the endangered species list.
