Threat ImpactMedium
Range Extent5000-20,000 square km (about 2000-8000 square miles)
Number of Occurrences21 - 80
Rank Reasons
Known only from higher elevations in a somewhat restricted geographical area (mostly Mono County, California, and Mineral County, Nevada with outlying occurrences in Inyo, Fresno, and Tulare counties, California). Threats include mineral exploration and development, road building, and possibly grazing. This species is currently known from approximately 40 occurrences; total population size may be less than 5000 plants, but up to date population data are needed to assess this.
Range Extent Comments
Mostly in Mono County, California, and Mineral County, Nevada (Bodie Hills, Glass Mountain, Wassuk Range, Brawley Peaks). In California, one outlying occurrences is present in each of Fresno and Tulare counties, and two specimens are known from Inyo County (NatureServe Network Database as of October 2018).
Occurrences Comments
In California, there are 31 presumed extant occurrences (CNDDB 2018). In Nevada, there are 11 extant occurrences (NatureServe Network Database as of October 2018).
Threat Impact Comments
In California, threats are few, including grazing, ORVs, and recreation (CNDDB 2018). In Nevada, threats are mineral exploration and development, road construction and maintenance (Morefield 2001). Lesser potential threats include competition and fire hazard from introduced exotics.
Ecology & Habitat

Diagnostic Characteristics

Arabis bodiensis could be confused with A. cobrensis based on the similarity of stem pubescence and with A. inyoensis based on the similarity of the widely spreading siliques. The gently curved, glabrous siliques distinguish A. bodiensis from the other two species (BLM 2007).

Habitat

Occurs at high elevations on rolling to steep topography; found on dry, open, rocky, high or north-facing slopes (often in rock crevices) and exposed rocky ridges and summits. Occurs on granitic, rhyolitic, or andesitic substrates. Occurs in high elevation Great Basin scrub (e.g. among Artemisia arbuscula and grasses), pinyon and juniper woodland, and subalpine lodgepole pine and whitebark pine forests. Preferred microsites include moisture-accumulating microsites in sagebrush associations, under shrubs, and on disturbed soils of prospector's diggings. 2050-3535 m. (Rollins 1993)
