Threat ImpactVery high - high

Range Extent1000-5000 square km (about 400-2000 square miles)

Number of Occurrences6 - 80

Rank Reasons

Rare regional endemic of western New Mexico and northeastern Arizona. Approximately 37 known sites within 3 metapopulations. The plants prefer specific substrates (outcrops of coarse-textured shales on the Baca Formation in west-central New Mexico and the Chinle Formation in northwestern New Mexico and northeastern Arizona) that are potentially minable. Threats include habitat disturbance, oil field activities, potential uranium mining activities, road construction and resulting erosion, and cattle grazing. Most of these threats are minor. Potential uranium mining activities could pose a serious threat in the future.

Range Extent Comments

Datil and Sawtooth Mountains in northern New Mexico. McKinley and Catron counties in the Cibola National Forest, and some on Bureau of Land Management public land in Catron County. Also found in Arizona on the east side of the Chuska Mountains in June 1999 (Sue Schuetze pers. comm. to Eric Nielsen 6/2000).

Occurrences Comments

Twenty small populations (or 37 sites) scattered over the Datil, Sawtooth, and Chuska Mountains in northern New Mexico and northeastern Arizona.

Threat Impact Comments

Habitat disturbance, oil field activities, potential uranium mines, road construction and resulting erosion, and cattle grazing. Ongoing drought is a threat to this species; climate change may exacerbate that threat.

Ecology & Habitat

Habitat

Pinyon-juniper woodlands on steep easily eroded sandstone slopes and clay banks, usually in close association with the Chinle and Baca Formations, at 2190-2400 m.
