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.<br/><br/>All occurrences on public lands are within active grazing allotments. Some occurrences are near ATV routes and may be impacted by ATV recreation (Fertig 2009 via UNPS Master List). 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.
