The Eastern Timber Wolf (Canis lupus lycaon) is an endangered subspecies of the
Gray Wolf and is native to
North America. "Timber wolf" used to refer to any North American wolf that lived within forested areas, but this designation has more recently been reserved for this specific subspecies of the grey wolf with the help of contemporary
genetic findings. Eastern Timber Wolves should not be mistaken for the
Eastern Canadian Wolf, Canis lycaon. Originally thought to be the same animal, new genetic testing and data has revealed that wolves occupying the
Algonquin Park region in Canada are actually a separate species more closely related to the
Red Wolf. There is still a great deal of turmoil in the scientific community as this change is being undertaken. This subspecies was the focal point of
L. David Mech's book The Wolf: The Ecology and Behavior of an Endangered Species (1970, University of Minnesota Press).
