 Exact population numbers of the swift fox are unknown, but it is known that they currently inhabit only 40 % of their historic range. In addition to its populations in Canada, there are also swift fox populations in the United States, ranging from South Dakota to Texas. In 1995, the U.S. Fish and Wildlife Service determined that the fox warranted an endangered listing, but other higher priority species precluded its listing. This prompted state wildlife agencies within the fox's range to create the Swift Fox Conservation Team, which worked to implement better swift fox management and monitoring programs. Populations in the United States are stable in the central part of its range, and it is not considered endangered in the United States. The IUCN Red List characterizes it as of Least Concern.
