Threats or limiting factors
The main threats are from habitat degradation due to grazing, energy and mineral extraction, drought, and road maintenance.
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. Some occurrences may be impacted by oil and gas extractions. 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).
