State Protection: Threatened
listed species are those with: 1) 6 to fewer than 20 extant sites, or 2) 1,000 to fewer than 3,000 individuals, or 3) restricted to not less than 4 or more than 7 U.S.G.S. 7 minute topographical maps, or 4) listed as threatened by U.S. Department of Interior.

Federal Protection: Not Listed

A State Rarity Rank of S2 means: This plant is threatened/imperiled in New York because of rarity (typically 6-20 populations or few remaining individuals) or is vulnerable to extirpation from New York due to biological factors.

Global Rarity Rank: G5
A Global Rarity Rank of G5 means: This species is demonstrably secure globally, though it may be quite rare in parts of its range, especially at the periphery.


Did you know?
This is the only species of Boechera in North America that has pick-shaped hairs on the lower stem. Even though it is an obvious biennial in our area, there are certain locations in the mountains of the West where the plants are definitely perennial. The common name refers to its former scientific name, "Arabis drummondii", after Thomas Drummond, an early 19th century Scottish botanist who explored the Rocky Mountains and southern U.S. "Boechera", the new genus name, is after the Danish botanist Tyge W. Bocher.

State Ranking Justification [-]
There are 11 current populations but most of them have fewer than 100 plants each. There are more than 30 historical populations, so more occurrences are expected to be found.
