Endangered Species
Mountain-Prairie Region

Species Description:  The Gunnison's prairie dog (Cynomys gunnisoni) is a yellowish buff color mixed with black above; slightly paler below with a short, white-tipped tail. It is approximately 12-14 inches in length, between
12-15 inches tall, weighing about 23–42 ounces.  The Gunnison's prairie dog is one of five species of prairie dog, all of which are native to North America. The Gunnison's prairie dog is a keystone species of the sagebrush ecosystem. They create habitat, provide food, and help keep the soil and plant communities healthy. For example, their abandoned burrows are used by burrowing owls, weasels, snakes, badgers, and even foxes. The prairie dog is an important food source for coyote, weasels, foxes, hawks, eagles, and the endangered black footed ferret. In addition, their burrowing helps to aerate the soil, add organic matter, and help to increase water penetration.

Location: The Gunnison's prairie dog occurs in the four corners area of Arizona, New Mexico, Colorado, and Utah.

Recent Actions:   Today, November 14, 2013, the Service announced the completion of a 12-month status review in response to a petition to list the Gunnison’s prairie dog as a threatened or endangered species.  The review has determined that protecting the Gunnison’s prairie dog under the Endangered Species Act is not warranted at this time.

The Service has determined that populations of the Gunnison’s prairie dog located in central and south-central Colorado and north-central New Mexico are warranted for protection under the Endangered Species Act.  However, listing these populations at this time is precluded by pending actions for other species with higher listing priorities.  The Service also determined that Gunnison’s prairie dog populations in Arizona, Utah, and elsewhere in Colorado and New Mexico are not warranted for listing.
