Rank Reasons
Cymopterus goodrichii occurs in the western United States where it is known the Toiyabe Range and Humboldt Range in central and west-central Nevada. Sites are on moderate to steep, slate or limestone scree and talus slopes in the subalpine and lower alpine zones. All known occurrences are on Federal lands managed by the U.S. Forest Service and Bureau of Land Management. Threats are unknown.
Range Extent Comments
Cymopterus goodrichii is endemic to Nevada in the western United States, where it is known only from the Toiyabe and Humboldt Ranges in Lander, Nye, and Pershing counties (Morefield 2001).
Occurrences Comments
Seven occurrences have been mapped. Although none are considered historical, some have not been visited recently and would benefit from re-confirmation. Some targeted surveys for this species have been conducted, but the survey effort has not been comprehensive (Morefield 2001).
Threat Impact Comments
Threats are largely unknown. There are mines in the vicinity of at least some occurrences and at least three occurrences appear to be within grazing allotments, but it is unknown whether either of these factors is actually impacting the species; grazing at least seems unlikely given the steepness and instability of many of the talus slopes on which it occurs. The species occurs over a relatively broad elevation range compared to other rare Nevada endemics and occurs in both the subalpine and alpine zones; therefore, researchers have suggested that it may be less vulnerable to climate change than more specialized Great Basin plants (Caicco et al. 2008).
Ecology & Habitat

Diagnostic Characteristics

Differs from other species of Cymopterus in its elongated, flexuous, narrow pseudoscape, small leaves, and short rays (Kartesz 1988, Weixelman and Atwood 1990).

Habitat

This species occurs on moderate to steep, often unstable scree and talus slopes of dark angular slate or limestone at elevations of 2,000 to 3,400 m. It is found in the subalpine and lower alpine zones and the surrounding community is often composed of shrubs and forbs (e.g., Cercocarpus-Holodiscus dumosus-Agropyron spicatum). Other associated species include Agropyron scribneri, Artemisia michauxiana, Astragalus platytropis, Chrysothamnus sp., Crepis nana, Draba arida, Erigeron compositus, Haplopappus macronema, Ipomopsis congesta , Leptodactylon pungens, Leucopoa kingii, Polemonium viscosum, Poa rupicola, Ribes cereum, and Ribes montigenum.
