Species range
Estimate from download of data from Utah Rare Plant Database on July 18, 2024.
Geocat 6 observations: Extent of Occurrence: 10,175.826 km2.
Used historic observations because only 2 were non historic.
Saline meadows at 1585 to 2565 m in Garfield, Iron, Juab, Kane, and Millard counties, Utah; Nevada (Lincoln, Nye, and White Pine cos.); essentially a Nevada Great Basin endemic, with extension onto the Markagunt and Paunsagunt plateaus in s. Utah (Welsh et al. 2015).
Threats or limiting factors
The main threats are from habitat degradation due to grazing, drought, and invasive plant species.
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. Almost all occurrences are within grazing allotments. Drought and climate change is also a threat and likely impacting this species through out it's range (Wrobleski, 2023). Competition with invasive plants may also be impacting this species.
