Distinctiveness (1=highest,4=lowest): 4 (nationally important)
This region contains some of the remnant prairie dog ecosystems which support predators including the endangered black-footed ferrets.*

Conservation Status (1=most endangered, 5=most intact): 3 (vulnerable)
Because of the aridity of the region which prevents cultivation, and the remoteness from human population centers, many areas have remained relatively intact.  Conversion from sagebrush habitat to reasslands for domestic grazing has degraded some areas severely.  Few areas are protected, and overgrazing, fire suppression, invasion by exotic grasses are threats.*

Characteristic species*
Agropyron (wheatgrass) species
Fescuta (fescue) species
Artemisia (sagebrush) species
