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

State Rarity Rank: S2
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: G4
A Global Rarity Rank of G4 means: This species is apparently secure globally (typically with more than 100+ populations), though it may be quite rare in parts of its range, especially at the periphery.


Did you know?
Virginia snakeroot's species and common name comes from its use by Native Americans and pioneers to cure rattlesnake bites. It was also used to treat fevers, toothaches, coughs, and disorders of the stomach and lung. The genus name is Greek for best (aristos) delivery (lochia) for its ancient use in child delivery.

State Ranking Justification [-]
With the exception of a few casual reports, this plant was absent from the New York flora for nearly 100 years. Numerous surveys tried to relocate this plant, but the focus was in areas that resemble its southern habitats. Not until 1994, when this plant was finally rediscoverd in New York, did we begin to understand its New York habitat. Since then, more surveys have been conducted in appropriate habitat and we know of at least six populations. As surveys continue, we expect to find more populations of this plant in the Hudson Highlands and the mid-Hudson Valley.
