This is the actual plan in paper work. Here on page 6 or the second paragraph of the preface they outline the two species and differentiate between the two. http://www.fws.gov/montanafieldoffi...rn_Rocky_Mountain_Gray_Wolf_Recovery_Plan.pdf "The Northern Rocky Mountain Wolf Recovery Plan outlines steps for the recovery of the gray wolf (Canis lupus) populations in portions of their former range in the Northern Rocky Mountains of the United States. Historical evidence documents the presence of gray wolves throughout the Northern Rocky Mountains of the contiguous United States. This subspecies (Canis lupus irremotus) was a predator on native ungulates under pristine conditions and later, as European Americans spread westward, on domestic livestock. Substantial declines in wolf numbers resulted from control efforts to reduce livestock and big game depredations. Currently, no viable populations of wolves occur in the Rocky Mountains south of Canada, however, at least one pack and several individual animals are known to be present."
