Threat ImpactLow
Range Extent5000-20,000 square km (about 2000-8000 square miles)
Number of Occurrences21 - 80
Rank Reasons
Nearly endemic to north-central Utah, mainly to the Wasatch Front, but there is a single collection from the southwest edge of the Uinta Basin (Utah). As of 2015, there were no major direct threats to this species found but there is development pressure along the Wasatch Front.
Range Extent Comments
Utah endemic of the Wasatch Range.
Occurrences Comments
As of 2015, there were 36 occurrences in the Utah Natural Heritage database, including 25 that are historic. There are 14 herbarium records collected after 1995 and some of those appear to be new occurrences, however they need to be assessed for overlap against records in the natural heritage database.
Threat Impact Comments
As of 2015, there were no major direct threats to this species found. While the seeds of this species are used in more than one native seeds programs, including the BLM's Seeds of Success program, and a program at the University of Idaho investigating commercialization of its seed for landscaping purposes (DeBolt and Spurrier 2004, NPC 2011), collection of seed for these programs does not appear to be a threat. However, most of the populations occur along the Wasatch Range, where there is considerable and ongoing development pressure.
