Number of Occurrences6 - 20
Rank Reasons
Endemic to eastern Utah and western Colorado in the Uinta Mountains and on the East Tavaputs Plateau. Potential threats include invasive species and oil and gas development.
Range Extent Comments
Known from eastern Utah and western Colorado on the south side of the Uinta Mountains and the East Tavaputs Plateau (Holmgren et al. 2005; Welsh et al. 2008; Ackerfield 2015).
Occurrences Comments
There are approximately six occurrences in Uinta County, Utah. In Colorado, (Garfield, Mesa and Rio Blanco counties) there are 19 principal occurrences documented; Thirteen of these are ranked historical (Colorado Natural Heritage Program database 2019).
Threat Impact Comments
Potential threats include invasive species and oil and gas development.
Ecology & Habitat

Habitat

In sand or silty sands derived from the Navajo formation, Shinarump member of the Chinle and Moenkopi formations, and Park City and Weber sandstone formations (Welsh et al. 2008). Found within a variety of shrub-dominated and coniferous forest/woodland communities, including ponderosa pine, lodgepole pine, Douglas fir, spruce-fir, sagebrush, black sagebrush, snowberry, and mountain mahogany communities at 2225 - 2960 m (Welsh et al. 2008).
