Prairie dog in prairie species such as the black-footed ferret, swift fox, golden eagle, red tailed hawk, American badger, coyote and ferruginous hawk. Other species, such as the golden-mantled ground squirrel, mountain plover, and the burrowing owl, also rely on prairie dog burrows for nesting areas. Even grazing species, such as plains bison, pronghorn, and mule deer have shown a proclivity for grazing on the same land used by prairie dogs. Nevertheless, prairie dogs are often identified as pests and exterminated from agricultural properties because they are capable of damaging crops, as they clear the immediate area around their burrows of most
Black-tailed prairie dog ("Carex duriuscula"), sixweeks grass ("Vulpia octoflora"), and scarlet globemallow. Grazing by black-tailed prairie dogs may also improve the nutritional qualities of some plants. On a shortgrass prairie near Fort Collins, Colorado, plant species diversity was greater inside black-tailed prairie dog colonies than outside of colonies, and perennial grasses such as buffalo grass and forbs increased. While black-tailed prairie dog colonies at Wind Cave National Park typically had lower levels of plant biomass and were dominated by forbs, plants growing on prairie dog colonies had higher leaf nitrogen concentrations than plants in mixed-grass prairie outside colonies.
