The Utah prairie dog, Cynomys parvidens, is one of three prairie dog species found in Utah, occurring in the southwestern part of the state. Interestingly, the species is not found anywhere else in the world, making it the only non-fish vertebrate endemic to (found only in) Utah. The Utah prairie dog is so rare that is has been Federally listed as a threatened species.
Similar to other prairie dogs, Utah prairie dogs form colonies and spend much of their time in underground burrows, often hibernating during the winter. The species breeds in the spring, and young can be seen above ground in late May or early June. The Utah prairie dog's diet is composed of flowers, seeds, grasses, leaves, and even insects. Major threats to the species include habitat loss (through development and drought), poisoning, and the plague.
