The Mackenzie wolf was originally found in the southern Rocky Mountains, the Midwest, eastern, northeast, and southwest Canada, and Southeast Alaska. It was exterminated in the United States outside of Alaska in the 1930s. After the introduction of the Endangered Species Act as a federal species protection law, it was able to spread across the Canadian border into Glacier National Park in Montana in the 1970s . In 1995 and 1996, 66 animals from Canada were released into the Yellowstone National Park and Idaho . They formed the basis of a population that in ten years expanded to such an extent that federal protection was no longer required in the states of Idaho, Wyoming, and Montana. Following legal disputes over the required level of protection in the jurisdiction of the federal states, the regional authorities in all three states have been responsible since the end of 2012.
