3.6.1. Special Status Plant Species

A list of special status species was requested from NNHP on January 27, 2009. They determined that no at risk taxa have been previously located in the area. However, habitat may be suitable for the New York Mountains catseye (Cryptantha tumulosa), a USFS (Region 4) sensitive species, and rosy twotone beardtongue (Penstemon bicolor ssp. Roseus). No sensitive or special status plant species were observed during the field surveys. The special status designation for each of these species is listed inTable 3.4, “List of Special Status Plant Species”.

Rosy two-toned beardtongue – The rosy two-toned beardtongue is a perennial herb that grows in rocky calcareous, granitic, or volcanic soils in washes, along roadsides, scree at outcrop bases, rock crevices, or other places that receive greater runoff (NNHCP 2005b and AHDMS). This species is only found in Clark and Nye counties in Nevada as well as parts of California and Arizona. It occurs at elevations ranging from 1,800-4,839 feet. This species tends to flourish with disturbance and is typically associated with creosote-bursage, blackbrush, and mixed-shrub zones. No rosy two-toned beardtongue was observed during the field surveys.

New York Mountains catseye – This species is only recorded in Nye and Clark counties in Nevada as well as in California. This perennial herb occurs at elevations between 4,480 and 9,900 feet above mean sea level (MSL). Little is known about the New York Mountains catseye, It has a global ranking of G4 – apparently secured (uncommon but not rare; some cause for long-term concern due to declines or other factors), and S2 – imperiled (imperiled in the jurisdiction because of rarity due to very restricted range, very few populations, steep declines, or other factors making it very vulnerable to extirpation from jurisdiction) (Natureserve 2009). This species is not likely to occur in the project area, which has an elevation range of 3,840- 3,870 feet.
