Species range
Estimate from download of data from Utah Rare Plant Database on Dec 6th, 2019. Geocat: 207 occs found: Extent of Occurrence: 3562.848 km2. Known only from Beaver, Iron, and Washington Counties in Utah, and Lincoln County, Nevada.
Threats or limiting factors
Threats mainly due to large scale mastication projects in the area and associated habitat loss, soil disturbance, and road development that cause habitat changes and introduction of invasive species. BLM requires surveys before conducting these projects. Threats would go up if removed from the BLM sensitive list and surveys were no longer conducted prior to ground disturbing activities. Electrical transmission line construction and maintenance may also be a threat (U.S. Department of the Interior 1992). The Utah Division of Water Resources reports that Utah is now in "extreme" or "exceptional" drought which is likely impacting this species in similar ways as it is other perennial forbs in Utah.
