Species range
Estimate from download of data from Utah Rare Plant Database on July, 29th 2025.
Geocat 4 observations: Extent of Occurrence: 298.229 km2.
Historic observations were included
Sagebrush and mountain brush upward to spruce-fir communities at ca 2440 to 3295 m in Duchesne, Summit, and Uintah counties, Utah as well as Canada south to Oregon, Idaho, Wyoming and the Dakotas (Welsh et al. 2015).
Threats or limiting factors
The main threats are from habitat degradation due to grazing, road maintenance and drought.
Threats compiled using observations and notes from Utah Rare Plant Database and Utah Geospatial Resource Center GIS Data downloaded in 2024. Severity of impacts are not well known so ranges are provided where appropriate. All occurrences are within grazing allotments. Occurrences are not known from mapped mountain goat habitat. Almost all occurrences are near roads and trails. Occurrences near roads may be impacted by maintenance. Drought and climate change is also a threat and likely impacting this species through out it's range (Wrobleski, 2023).
UNPS Alexander 2015: A taxon not included in previous versions of the UNPS Rare Plant list, but its apparent rarity in Utah warrants further research. Only 5 specimens at BRY have been collected. It has been found only in the Uinta Mountains in Duchesne, Summit and Uintah Counties in Utah. This taxon's primary range is in the Pacific Northwest, the Rocky Mountains and Canada. Habitat Specificity scored as "0" since the habitat is variable and does not seem unusual according to A Utah Flora ("Sagebrush and mountain brush upward to spruce-fir communities") and FNA ("Prairies, riparian woods, and coniferous, deciduous, and mixed forests"). Threats to this taxon include grazing-related impacts from cattle, sheep, and naturalized mountain goats. Goats were introduced by the State of Utah for trophy hunters. Climate change is also a threat. Droughts and rapid snowmelt due to wind-blown sediments are melting snowpack earlier than normal in our region. These are the primary reasons for the upgrade of the threats to this species to a "1". Trends are scored as "unknown" due to uncertainty of the magnitude of the impacts of disturbance on extant populations and the lack of population-level surveys. It is a high priority to monitor these alpine endemics that may be impacted by naturalized animals introduced by the State of Utah. This taxon is ranked on the "Medium" list.
