ENDANGERED SPECIES ACT PROFILE

PROTECTION STATUS: Not listed

PETITIONED: 2007

RANGE: Utah’s west desert, Wasatch Front, and the Sevier River

THREATS: Urbanization, water development and groundwater pumping, livestock grazing, and competition from nonnative species

POPULATION TREND: The decline of the least chub was first noted in the 1940s. By 1996, local extirpations in many areas where this fish was once abundant set it on the path to the brink of extinction, with only six remaining wild populations intact.
