Threats or limiting factors
Threats to this species are not well documented. Threats compiled 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.
Most known occurrences are within active grazing allotments. Although not palatable some threat from trampling may still occur. Some occurrences are near transmission lines and roads and may be impacted by road maintenance and competition from invasive species. The Utah Division of Water Resources confirmed the Utah is now in "extreme" or "exceptional" drought which is likely impacting this species in similar ways as it is other perennial forbs in Utah.
