Rank Reasons

Endemic to California, Dedeckera eurekensis is known from approximately 29 occurrences in Inyo and Mono counties. It is known from a number of disjunct localities in the mountains at the northwestern fringes of the Mojave Desert. Populations range in size from only two plants to many individuals. Mining is a threat to this taxon. Also, the occurrences which consist of small populations are very easily impacted. Additional threats include OHV use and grazing. Only a few occurrences in Death Valley may be well protected; more is needed to protect this species.

Range Extent Comments

California endemic found in Inyo and Mono Counties.

Occurrences Comments

Twenty-nine element occurrences are known, plus two additional field forms that are unprocessed. Eleven element occurrences are historical, but may likely still be extant.

Threat Impact Comments

At least some of the plants occur in fairly remote, desert canyons. But, some are affected by OHVs, mining, grazing, recreation, possibly weeds, such as Salsola spp. and Bromus spp.
