Rank Reasons

Ericameria watsonii occurs in Nevada, Utah and Arizona in xeric communities including sagebrush, pinyon-juniper, mountainbrush, and ponderosa pine communities (Van Buren et al. 2011). Information is needed about population abundance throughout its range. Known threats are localized in the Great Basin and include sheep grazing, ORV use, and damage to alpine and subalpine areas from recreational use (SOMC 2014).

Range Extent Comments

This species occurs in Utah (Beaver and Millard Counties), Nevada, and Arizona (Van Buren et al. 2011). The extent of occurrence was calculated based on data from SEINet during the 2018 conservation status review.

Threat Impact Comments

Rangewide threats are not known, however, local threats are known. In the Great Basin National Park domestic sheep grazing, illegal OHV use and recreation activities in alpine and subalpine areas are threats to this species (SOMC 2014).
