Number of Occurrences6 - 20

Rank Reasons

Only six populations known to be extant, all apparently in good to fair condition within the Sierra National Forest. Camping poses a potential threat to one of the occurrences. The greatest threat to the species is climate change as its habitat requirements include a sliver of area in the subalpine Sierra Nevadas, California. Further, in these subalpine areas plants are found in very open coniferous forest, at high elevations and in bedrock crevices where humus has accumulated.

Range Extent Comments

California endemic from Madera county and calculated at 5 sq km (CNDDB 2008).

Occurrences Comments

Six presumed extant occurrences, three described as in "excellent" condition, two as "good", and one "fair" (California Natural Diversity Database, 1997, 2010).

Threat Impact Comments

One population is threatened by people camping, but there are no recorded threats for other occurrences (California Department of Fish and Game, 1997, 2010). Given that this species is highly restricted in its range, and occurs in a subalpine habitat, makes it vulnerable to climate change. Further, Shevock et al. (1990) mention that a shift to a warmer and drier climate could lead to a smaller area of available habitat and an increase in fragmented habitat. Fragmented habitat can have adverse affects not only in available habitat, but also in increasing the distance by which pollination is to take place.

Ecology & Habitat

Habitat

In upper montane coniferous forest, meadows, subalpine coniferous forest. Growing on rocky graitic outcrops and slopes; 2060 - 2550 m altitude (California Department of Fish and Game, 1997).
