The Wolf Equation
In the winter of 1976-77, 80 percent of the wolf population in Northwest Alaska was the target of aerial hunts. Although the area is roamed by the Western Arctic caribou herds—a natural predator of the wolf—the caribou population has been steadily decreasing in number. NOVA examines how the Dept. of Fish and Game is handling the the problem of wolf control.
