Threats or limiting factors
(UNPS, accessed 2024): A taxon not included in previous versions of the UNPS Rare Plant list, but its apparent rarity in Utah warrants further research. Only 6 specimens at BRY have been collected. It has been found only in the Bear River Range in Cache County in Utah. This taxon's primary range is in the Rocky Mountains. Habitat Specificity scored as "1" since it appears to be a calcareous rock crevice species according to A Utah Flora ("Crevices, often in limestone or dolomite in the spruce-fir community"). Threats and Trends are scored as "unknown" due to uncertainty of the magnitude and type of the impact of disturbance on extant populations and the lack of population-level surveys. This taxon is ranked on the "Watch" list.
