Impacts on Endangered Species

Threatened and endangered plant and animal species inhabiting federal rangelands and imperiled by livestock grazing: more than 175.

Rank of livestock grazing as a cause of species endangerment in

...southern Arizona and western New Mexico                                                              No. 1

...southern Nevada and central Arizona                                                               No. 3

...California                                                                                                   No. 4

...northern Arizona, southern Utah and southern Colorado                  No. 5

In the United States, grazing has contributed to the demise of 22 percent of federal threatened and endangered species—nearly equal to logging (12 percent) and mining (11 percent) combined.

Livestock grazing is especially harmful to plant species, affecting 33 percent of endangered plants.

Sensitive Focal Species Harmed by Livestock Grazing includes:

  • Greater sage-grouse
  • Gunnision sage-grouse
  • Pronghorn (especially Sonoran subspecies)
  • Bighorn sheep (California subspecies and Rocky Mountain subspecies)
  • Black-footed ferret
  • Wolf
  • Grizzly bear
  • Yellow-billed cuckoo
  • Prairie dog (black-tailed, Gunnison's, Utah, white-tailed)
  • Mexican spotted owl
  • Lesser prairie chicken
