Number of Occurrences1 - 20
Rank Reasons
Known only from the Kaibab Plateau in northern Arizona. Occurs in an area of only about a dozen square miles (Reichenbacher 1986 cited by AGFD 1992). It was apparently fairly abundant within this area (AGFD 1992). Populations have decreased, and plants are now only known from three general areas (AGFD 2012). Herbarium specimens should be reviewed to assess trends in populations since new specimens have been collected since 2012.
Range Extent Comments
Local endemic with distribution on Kaibab Plateau, Coconino County, Arizona. From Demotte Park, Little Park, and the Basin NW of Kaibab Lodge (John Spence, AGFD 2012).
Occurrences Comments
A few populations (3 element occurrences and possibly more site represented in recent herbarium collections, 2015) on the Kaibab Plateau, Arizona, north of the Grand Canyon. (John Spence, AGFD 2012)
Threat Impact Comments
Threatened by grazing (N. D. Maschinski). Bison have moved in from the bison ranch (also known as buffalo ranch) below and to the east of the plateau, and are now grazing in the meadows (John Spence pers. comm. 2012).
