Threat ImpactMedium
Range Extent5000-20,000 square km (about 2000-8000 square miles)
Number of Occurrences6 - 20
Rank Reasons
Endemic to the Klamath Mountains in northern California and adjacent Oregon. Approximately 20 occurrences are known. Threats include grazing.
Range Extent Comments
Klamath Ranges in northern California and Josephine County, Oregon.
Occurrences Comments
Eighteen occurrences in California and two in Oregon (Element occurrence data in the NatureServe central database as of August 2015).
Threat Impact Comments
Overgrazing by cattle is at threat at several sites (Element occurrence data in the NatureServe central database as of August 2015). One site notes possible development into a helicopter landing and ORV use (Element occurrence data in the NatureServe central database as of August 2015). Calculated as moderately vulnerable to climate change (Oregon Biodiversity Information Center 2013).
Ecology & Habitat

Habitat

Habitat is open stony ground in relatively sunny areas at moderate to higher elevations (Rolle 2013). "These are dry upland habitats but microsites where the phacelias grow are often vernally moist" (Rolle 2013). Upper montane coniferous forest openings; sometimes serpentinite (Skinner, 1997). Sandy flats, slopes, conifer forest, 1200-2750 m (Baldwin et al. 2012).
