It was questionable science (or possibly incompetence) that allowed Canadian MacKenzie Valley Gray Wolf, subspecies Canis lupus occidentallis, to be introduced to the contiguous United States where it is not an indigenous species and cannot, therefore, be said to be an endangered species and where it did displace / replace Canis Lupus Irremotus - the original Northern Rocky Mountain Timber Wolf.
The Endangered Species Act of 1973 states: The purpose of this act ...
"to provide a means whereby the ecosystems upon which endangered species and threatened species depend may be conserved, to provide a program for the conservation of such endangered species and threatened species, and to take such steps as may be appropriate to achieve the purposes of the treaties and conventions set forth in subsection (a) of this section." (Section 2(b))
From Section 3(6):
"The term 'endangered species` means any species which is in danger of extinction throughout all or a significant portion of its range ..."
The subspecies Canis lupus irremotus was listed as endangered on June 4, 1973, by the Secretary of the Interior. That listing was recorded in the Federal Register on that date, referenced as 38 FR 14678 which means Volume 38, Federal Register, page 14678.
