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 2023. Severity of impacts are not well known so ranges are provided where appropriate.
About half of known occurrences are within active grazing allotments and may be subjected to trampling and other grazing related impacts by livestock. Nonrenewable energy development may be a threat to this species and includes impacts from oil and gas development and associated roads. Multi use trails are near more than half of the known occurrences where plants may be impacted by recreational use as well as road maintenance. Public lands near Capitol Reef National Park are being impacted more and more by dispersed camping although it's unclear if this is a threat.
