The U.S. Fish and Wildlife Service has issued a final rule that declared the eastern puma (Puma concolor couguar) extinct. This review process began in July 2015, when the USFWS initiated the standard five-year status review of this species.
This subspecies was endemic to the eastern half of the United States and is genetically similar to the Florida panther (Puma concolor coryi) and the western subspecies of the North American cougar (Puma concolor). The last confirmed sighting of an individual was reported in 1938.
