State Protection: Endangered
listed species are those with: 1) 5 or fewer extant sites, or 2) fewer than 1,000 individuals, or 3) restricted to fewer than 4 U.S.G.S. 7 minute topographical maps, or 4) species listed as endangered by U.S. Department of Interior.

Federal Protection: Not Listed

State Rarity Rank: S1
A State Rarity Rank of S1 means: This plant is endangered/critically imperiled in New York because of extreme rarity (typically 5 or fewer populations or very few remaining individuals) or is extremely vulnerable to extirpation from New York due to biological factors.

Global Rarity Rank: G5T5?
A Global Rarity Rank of G5T5? means: Secure globally (most likely) - Conservation status of the subspecies/variety is uncertain, but is most likely common in the world; widespread and abundant (but may be rare in some parts of its range). More information is needed to assign a firm conservation status. (The species as a whole is common globally.)


Did you know?
Special structures known as "hydathodes" secrete liquids from the tips of the basal leaves of White Mountain-saxifrage. The dissolved salts left behind form striking rows of white lime deposits along the leaf margins.

In the Arctic, native people traditionally made a "sauerkraut" from the this species by tightly packing the leaves into a sealskin bag and allowing them to ferment (Aiken et al 2003).

State Ranking Justification [-]
