Number of Occurrences1 - 20
Rank ReasonsEndemic to high elevations in the La Sal Mountains of Grand and San Juan counties, southeastern Utah. Though locally abundant, the narrow alpine environment of the La Sal Mountains is experiencing increased traffic by recreational users: the turfy, easily walked-on habitat serves as the pathway across the range's narrow 'spine', resulting in trampling. In addition, a portion of the habitat has patented mining claims with a high potential for exploratory activities in the near future. Introduced mountain goats, combined with other threats, present concern for this species' conservation. With the addition of the mountain goat threat, the calculated conservation rank increased from G2 to G1 during the 2017 rank review.
Range Extent CommentsThis species occurs only in the La Sal Mountains in Grand and San Juan counties, Utah in the Western United States.
Occurrences CommentsThere are three extant element occurrences and four that are historical. A review of herbarium specimens found 4 collections made after 2008 (herbaria: ASC, RM, BRY). The Utah Native Plant Society indicates that there are 15 specimens located in the BRY herbarium (Alexander 2016).
Threat Impact CommentsThreatened by trampling by recreationist. In addition, a portion of the species' habitat has patented mining claims with a high potential for exploratory activities in the near future. The combination of the effects of climate change could compound with the effects of other threats. Introduced mountain goats in the La Sal Mountains present a high threat to this species (UNPS 2016).
