Human-caused changes to the grasslands stemming from crop agriculture, livestock grazing, energy development, residential and commercial development, prairie dog shooting, poisoning campaigns and plague (an introduced disease) have caused the five species of prairie dogs to disappear from an estimated 87-99% of their historic (1800s) range, depending on the species.
Why do prairie dogs exist?
First, prairie dogs act as water conservationists. While humans have devastated the water features of the Great Plains –by damming up rivers and streams for crop and livestock agriculture, and by overgrazing of riparian areas by livestock– prairie dogs increase the ability of an arid region to conserve what little water falls from the sky.

The soil erosion we tend to see is often due to overgrazing by cattle, which has been well demonstrated by numerous studies (Schlesinger et al. 1990, Van Auken 2000, Reynolds et al. 2007). It is important to keep in mind that black-tailed prairie dogs prefer open patches of grassland, and will move into heavily grazed patches of grassland.

Why are prairie dogs important?
Keystone species are incredibly important to their ecosystems, and if removed, the ecosystem itself may collapse. Prairie dogs serve as a prairie keystone species by getting eaten, making homes for other animals, clipping vegetation, and much more.
What do prairie dogs eat?
Prairie dogs vary their diet, so they aren’t reliant on a single plant for survival. When they eat the grasses around their town, many positive effects click into place. Trimmed grass helps increase visibility, allowing prairie dogs to detect predators more quickly. Additionally, when prairie dogs eat away at grass, they make new space for plants like forbs and weeds. Prairie dogs will eat forbs in addition to their frequent diet of grass, and the change in growth and plant type brings more grazers, like bison and pronghorn, to prairie dog towns.#N#As the winter approaches, prairie dogs eat more and more food to fatten up for the colder season. Although they fatten up, prairie dogs don’t hibernate for the winter. Instead, they will go into a state of torpor. In torpor, an animal’s body temperature, breathing rate, and metabolic rate all decrease. The animal becomes lethargic, but unlike a hibernating animal, is still awake. Although prairie dogs are in a state of torpor, the activities of prairie dog towns remain slow but normal throughout the winter season.#N#When spring comes around, prairie dogs come out of torpor and resume their typical activities. Starting in March and continuing through early April, prairie dogs mate. The gestation period for a prairie dog is just one month, and when prairie dogs give birth, they usually do so in litters of 1-6. Pups are born blind and hairless. Pups stay underground in their coterie for about 6 weeks, until they are ready to emerge from their burrows.#N#One unique aspect of prairie dog life is communication. Some scientists believe that prairie dogs have one of the most complex animal languages ever decoded. Although a prairie dog’s “bark” may sound like a simple squeak or yip to us, it means much more to a prairie dog’s ear! On a basic level, prairie dogs can signal different threats. For example, they can communicate the difference between a coyote and a domestic dog. In fact, scientists think that prairie dogs may have developed such complex language from a need to respond to a diverse array of predators, all with different hunting strategies. In addition to identifying specific threats, prairie dogs can further communicate size, shape, color, and speed. A prairie dog can say so much more than, “A human is approaching!” They can get as specific as, “A tall human in a blue shirt is approaching rapidly!”
