Rank Reasons
Endemic to high elevations in the Uinta Mountains, northeast Utah. There are two significant threats to this species: introduced mountain goats and climate change. In 2016 the Utah Native Plant Society commented that the conservation priority for this species was increased due to the unknown, but potentially significant, impact that the expanding mountain goat populations could have on this species. Additionally, the threat of climate change is also a concern due to the high elevation at which this species occurs.
Range Extent Comments
Utah: Daggett, Duchesne, Summit (questionable), Salt Lake, Uintah, and Utah counties (Alexander 2016). Endemic to the Wasatch and Uintah mountains, Utah.
Occurrences Comments
There are at least 24 occurrences confirmed mostly by herbarium vouchers housed in Brigham Young (Alexander 2016).
Threat Impact Comments
The threat level for this alpine species was considered low in 2009 by the Utah Native Plant Society, however, in their 2016 review it was considered a high conservation priority given the increase in naturalized mountain goats in the Uintah and Wasatch Mountains. These non-native mountain goats, introduced in 2014 into the La Sal Mountains, and other grazing cattle are the primary threat to this species. Additionally, climate change is considered a threat to alpine environments where this species inhabits (Alexander 2016).
