Before, the black-footed ferret's range was from southern Alberta and southern Saskatchewan south to Texas, New Mexico, and Arizona. In 2007, the only known wild black-footed ferret population was found in the western Bighorn Basin near Meeteetse, Wyoming. Since 1990, black-footed ferrets have been reintroduced into the following places: Shirley Basin, Wyoming; UL Bend National Wildlife Refuge and Fort Belknap Indian Reservation, Montana; Conata Basin/Badlands, Buffalo Gap National Grassland, and the Cheyenne River Sioux Reservation in South Dakota; Aubrey Valley, Arizona; Rocky Mountain Arsenal National Wildlife Refuge and Wolf Creek in Colorado; Coyote Basin, and Grasslands National Park, Canada.
