Species range
Estimate from download of data from Utah Rare Plant Database on Dec 1st 2022.
Geocat 35 observations: Extent of Occurrence: 1,175.362 km2.
Historic observations over 40 years old were not used.
Salt desert and mixed desert shrub and juniper-sagebrush communities at ca 1675 to 1925 m in Juab, Sevier, and Piute cos. (on Jurassic Arapien, gypsiferous shale and clays thinly overtopped by igneous rubble); a Utah Great Basin endemic (Welsh et al. 2015).
Threats or limiting factors
Threats include impacts from livestock trampling and grazing, competition from invasive species especially cheat grass, impacts from power line maintenance, and ATV use. Threats compiled from Utah Native Plant Society comments as well as using observations and notes from Utah Rare Plant Database and Utah Geospatial Resource Center GIS Data downloaded in 2022. Severity of impacts are not well known so ranges are provided where appropriate.
Almost all occurrences are within active grazing allotments. Grazing impacts are likely similar to those in the closely related and federally listed species Townsendia aprica where the US Fish and Wildlife service notes "Cattle and range improvements effect 90% of known occurrences. Includes: direct physical injury and mortality in individuals, vegetation disturbance, soil removal disturbance, erosion, and disturbance to pollinators" (USFWS 2013). Some occurrences near Sigurd are within transmission line corridors. Several occurrences are within oil and gas fields and one observation un Utah Rare Plant Database notes oil and gas drilling as a threat (URPD 2025). There are occurrences along ATV trails near Salina.
