Rank ReasonsEucephalus engelmannii occurs in Alberta and British Columbia in Canada south through Washington, Idaho, Wyoming, and Montana to California, Nevada, Utah, and Colorado in the U.S.A. It occurs in major mountain ranges including the Rocky Mountains, Sierra Nevada, and the Cascade Ranges. The species is widespread in fairly common habitats with no pervasive threats known.
Range Extent CommentsEucephalus engelmannii occurs in Alberta and British Columbia in Canada south through Washington, Idaho, Wyoming, and Montana to Nevada, Utah, and Colorado in the U.S.A. (FNA 2006b). It occurs in major mountain ranges including the Rocky Mountains, Sierra Nevada, and the Cascade Ranges. It is noted to occur in the Ruby Mountains of Nevada. The Jepson Flora (2019) reports this species from northern California where it is uncommon in the Klamath and High North Coast Ranges.
Occurrences CommentsThe number of occurrences is not know and given the species presence in mountainous areas, some of which are remote, it is likely underreported in herbarium or observation collections.
Threat Impact CommentsThreats are not documented for this species but expected to be low, given the remoteness of the habitat throughout much of the species range.
