Rank Reasons
Arabis pygmaea is endemic to California and is found in Tulare and Inyo counties. It occurs in meadows and the edges of seeps in subalpine coniferous forest, and specifically, grows on volcanic or granitic soils that are gravelly or sandy. It is found at high elevations, between 2315 and 3400 meters. While A. pygmaea is considered rare, it is found in sufficient enough numbers that the potential for extinction is currently low, and further, it is not considered very endangered (CNPS 2001).
