Rank Reasons

Claytonia obovata does occur in a specialized habitat, however at least 20 occurrences have been documented with more suspected across its range and overall threats are low.

Range Extent Comments

Found in the Klamath-Siskiyou region of northwestern California in the North Coast Ranges to southwestern Oregon at Abbott Butte (Stoughton et al. 2017).

Occurrences Comments

20 documented occurrences, but likely more undocumented occurrences across the range (K. Lazar, pers comm. May 2020).

Threat Impact Comments

There are no known direct threats. The majority of its occurrences in National Forest Service lands should offer some protection from development and other threats in California. Occurrences are typically in remote areas, unlikely to be logged or frequented by people (K. Lazar, pers. comm., May 2020).

Ecology & Habitat

Habitat

Generally on north-facing, stony and talus slopes comprised of siliciclastic or carbonate-dominated (meta)sedimentary rocks (e.g. grey-wacke, limestone, shale), or mafic substrates (e.g. gabbro, peridotite, serpentinite), and in soils derived from these parent materials. Most often found in openings of subalpine forest habitats from ca. 1,200 to ca. 2,200 m. (Stoughton et al. 2017).
