Black Tailed Prairie Dog

The population of black tailed prairie dogs in North America has decreased dramatically during the past 100 years. There was once 5 billion of them inhabiting North America. The three main causes of the decline: 99% of their habitat has been lost, large scale poisoning of their colonies, and the introduction of disease from Asia. At Devils Tower National Monument, their population is on the rise.
