Threat ImpactHigh
Range Extent5000-20,000 square km (about 2000-8000 square miles)
Number of Occurrences6 - 20
Rank Reasons
Cordylanthus tecopensis is known from approximately ten extant occurrences across a narrow range in California and Nevada. Its habitat of alkali meadows is generally heavily impacted in desert areas; thus, this is a threat to this species.
Range Extent Comments
Inyo and San Bernardino Counties in California and Esmerelda and Nye Counties in Nevada. Report of this taxon in Oregon is erroneous (J. Kagan).
Occurrences Comments
4 element occurrences in California, and 6 in Nevada.
Threat Impact Comments
Alkali meadow areas, generally heavily impacted in desert areas. Specific threats that exist to this species in California are urbanization, trash dumping, habitat disturbance from a nearby rail road, altered hydrology, and other types of disturbance (CNDDB 2003). This species is on the Nevada rare plant list, but no specific threats are mentioned.
