After an absence of more than 50 years, the swift fox has returned to the grasslands of the Fort Belknap Indian Reservation in Montana. From September 12 to 20, the Assiniboine (Nakoda) and Gros Ventre (Aaniiih) Tribes of Fort Belknap released 27 swift foxes in collaboration with the Smithsonian Conservation Biology Institute, Defenders of Wildlife and World Wildlife Fund (WWF), kickstarting a five-year swift fox reintroduction program.
