Rank ReasonsLomatium shevockii is a perennial forb occurring on slopes and talus in open coniferous or pine/oak woodlands of the western United States, where it is endemic to Kern County, California in the Sierra Nevada Mountains. This is a very narrow endemic species, with only two occurrences known near the summit of Owens Peak and nearby Mt. Jenkins, containing fewer than 1,000 individuals total. Given the rugged and remote habitat of this species, threats are presumed to be minimal. However, the original construction of the Pacific Crest Trail runs through or close to populations and likely impacted plants. All occurrences are located within the Owens Peak Wilderness Area, which is managed by the Bureau of Land Management.
Range Extent CommentsLomatium shevockii occurs in the western United States, where it is endemic to Kern County, California in the Sierra Nevada Mountains (CalFlora 2025). Specifically, it is known from just two locations near the summit of Owens Peak and nearby Mt. Jenkins (Hartman and Constance 1988). The range extent was estimated to be one square kilometer.
Occurrences CommentsOnly two small occurrences are known, both located in or near the Owens Peak Wilderness Area (CNPS 2025).
Threat Impact CommentsThe extremely steep, rugged terrain Lomatium shevockii inhabits likely protects it from most human disturbance (Hartman and Constance 1988). The Owens Peak region of the Sierra Nevada is primarily used for recreational activities (Fraga 2008). Notably, the Pacific Crest Trail (PCT) runs along the east side of Mount Jenkins, with spur trails running to the summits of each peak, including Owens Peak. The construction of the PCT may have impacted individuals when the trail was built. Invasive species are also considered to be a threat to this species (CNPS 2025).
