NatureServe Status

Global Status: G2
Global Status Last Reviewed: 11Mar2016
Global Status Last Changed: 03Jul1995
Ranking Methodology Used: Ranked by calculator
Rounded Global Status: G2 - Imperiled
Reasons: Known only from higher elevations in a somewhat restricted geographical area (mostly Mineral County, Nevada and Mono County, California, 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 22 presumed extant occurrences; total population size may be less than 5000 plants, but up to date population data are needed to assess this.
Nation: United States
National Status: N2

NatureServe Global Conservation Status Factors

Range Extent Comments: Mostly in Mineral County, Nevada (Wassuk Range, Brawley Peaks, Bodie Hills) and Mono County, California (Bodie Hills and Glass Mountain). In California, one outlying occurrences is present in each of Fresno and Tulare counties, and one specimen is known from Inyo County (CNPS 2009, Consortium of California Herbaria 2008).

Area of Occupancy: 6-125 4-km2 grid cells
Area of Occupancy Comments:  

Number of Occurrences: 21 - 80
Number of Occurrences Comments: 22 occurrences are presumed extant, 11 in Nevada and 12 in California. An additional 8 occurrences in California and 1 occurrence in Nevada are historical.

Population Size Comments: Population estimates are out of date. As of 2001, the total number of individuals in Nevada was estimated to be 2048. Among California occurrences, counts of five occurrences yielded 63 individuals in total, and plants were described as "scarce" at another three occurrences. Plant numbers are unknown at the remaining three presumed extant occurrences in California.

Number of Occurrences with Good Viability/Integrity: Few (4-12)

Overall Threat Impact: High
Overall Threat Impact Comments: In California, threats are few. Two occurrences in Mono Co. may be impacted by grazing; one may be visited by sheep once or twice a year and the other is too rocky for cattle (CNDDB 2003). In Nevada, threats are mineral exploration and development, road construction and maintenance (Morefield 2001). Lesser threats include high-intensity grazing, competition and fire hazard from introduced exotics, and ORV use.

Short-term Trend: Decline of 10-30%
Short-term Trend Comments: Nine occurrences are historic.

Ecology & Life History
Help
Basic Description: A perennial herb, 1.5-3.5 dm tall, with white to pinkish flowers blooming April-July.
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).
Duration: PERENNIAL, Long-lived
Terrestrial Habitat(s): Alpine, Bare rock/talus/scree, Forest - Conifer, Forest/Woodland, Shrubland/chaparral, Woodland - Conifer
Habitat Comments: 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 propector's diggings. 2050-3535 m.
