Species range
The narrow range of this species is approximately 10km (6mi) wide by 128km (80 mi) long. The area makes-up a shape that looks like a curved band. The species is known from the area in Utah where the Carbon, Duschesne and Uintah counties meet in the Sand Wash and Nine Mile Creek drainages. The range extends east across the Utah border into Colorado and north to Rio Blanco County, Colorado (USFWS 2006).
Threats or limiting factors
The primary threat energy exploration and development. Invasive species, such as cheatgrass (Bromus tectorum) and saltlover (Halogeton glomeratus) are also found at sites where this rare species grows. Additionally, grazing may represent a threat (USFWS 2006).
