While we were growing up in Wisconsin during the 1950s and 1960s, gray wolves (we always called them timber wolves, Canis lupus) were making their last stand in northern Wisconsin. Wolves were considered a wilderness-dependant relic of Wisconsin’s frontier past that no longer belonged in our state. We did not expect wolves to ever again return to the state, at least not in any sizeable numbers. Among us, Dick Thiel was the most tenacious about trying to find evidence of wolves in Wisconsin, even as a student in the 1960s and 1970s. When wolves began returning during the mid-1970s, we dared not hope for any more than a token population of wolves to reestablish. The recovery of wolves in Wisconsin has succeeded beyond our wildest dreams. We have had the pleasure to document and track the amazing return of this powerful predator to our state.
