Gunnison’s prairie dog (Cynomys gunnisoni) | ESA status: none

Gunnison’s prairie dog

Gunnison’s prairie dogs live in interdependent colonies and communicate using a complex series of calls. Despite their many similarities to humans—they are social, intelligent animals with a sophisticated communication system—this species has been persecuted for decades.

Gunnison’s prairie dog habitat

The range of the Gunnison’s prairie dog includes the “Four Corners” region of Arizona, southwestern Colorado, northwestern New Mexico, and southeastern Utah.

Communication in the colony

Gunnison’s prairie dogs live in family groups called clans, organized into colonies with their neighbors. Their use a complex series of calls to warn each other of predators, such as the coyote, badger, golden eagle, and ferruginous hawk. The prarie dogs have specific calls for specific predators, and each call elicits a different escape response or behavior.

A keystone species

Gunnison’s prairie dogs are considered a keystone species because of the important role they play in their grassland habitat: as well as (unwillingly) providing meals for predators including the endangered black-footed ferret, they dig burrows that host a variety of other animals, including snakes, cottontail rabbits, burrowing owls, beetles, and salamanders, to name a few. Their burrowing behavior turns and aerates the soil and increases water penetration into the ground.

Gunnison’s prairie dog fun facts

Slow multiplier

Female Gunnison’s prairie dogs are receptive to mating for only one day a year. They have one litter of three to four pups per year; typically, only half of these survive to adulthood.

Heavy sleeper

Gunnison’s prairie dogs enter “torpor” in the winter—they curl up and drop their body temperatures to between 41 and 59 degrees Fahrenheit. Their muscles lock and they remain motionless for up to eight days, waking up and moving about their burrows for a day before repeating the cycle.

What are the threats to Gunnison’s prairie dogs?

This intelligent, social, and important animal occupies a tiny fraction of its former range. In 1916, Gunnison’s prairie dog colonies stretched across 24 million acres of the Great Plains. Now, the prairie dogs occupy fewer than 500,000 acres, a decline of almost 98 percent. Mass extermination efforts, federally orchestrated on behalf of the livestock industry, jump-started the prairie dogs’ decline. Currently, they are under siege from introduced sylvatic plague, rampant oil and gas drilling, shooting, poisoning, urban sprawl, and other perils.

What WildEarth Guardians is doing to save the Gunnison’s prairie dog

We are working hard to preserve the Gunnison’s prairie dog. In the past decade, we have fought political interference and misuse of the scientific process in Endangered Species Act decisions. In 2013, the U.S. Fish and Wildlife Service denied Endangered Species Act protection to the Gunnison’s prairie dog, and we are currently working to create local management plans that reduce or eliminate lethal control of this important species.
