Fact Sheet
The black-tailed prairie dog is a member of the squirrel family. Of the five species of prairie dogs in western North America, only the black-tailed prairie dog lives in the Great Plains.
Species at Risk
The five species of prairie dogs were once likely more than one billion strong, and their colonies covered roughly 100 million acres. Since the late 1800s, their numbers have been reduced by at least 95 percent.
