Range Extent250-20,000 square km (about 100-8000 square miles)

Number of Occurrences21 - 80

Rank Reasons

Narrowly endemic to Wyoming's Wind River and Green River basins, where it is often locally abundant; 32 occurrences are known as of 2010. Threats include surface disturbance from oil and gas activities, and highway construction.

Range Extent Comments

Endemic to the Wind River and Green River basins and southeastern foothills of the Wind River Range in Fremont, Lincoln, and Sublette counties, Wyoming. The "typical" form is restricted to Fremont County, and the "Ross Butte morph" is restricted to the Green River Basin in Lincoln and Sublette counties.

Occurrences Comments

Known from 32 extant occurrences in Wyoming, all of which have been discovered or relocated since 1990 (last observed in 2010) and one record past flower that is questionable.

Threat Impact Comments

Surface disturbance associated with oil and gas development, pipeline construction, and highway construction are potential threats (Dorn 1990), particularly around oil fields of Sublette and Lincoln counties (Heidel 2009).

Ecology & Habitat

Habitat

Sparsely vegetated slopes on sandstone, siltstone, or limestone (in the Wind River Basin) and on clays and shales (in the Green River Basin). 1830-2250 m elevation.
