New York Natural Heritage Program
Hydrastis canadensis L.
Family: Buttercup Family (Ranunculaceae)

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: G3G4
A Global Rarity Rank of G3G4 means: Vulnerable globally, or Apparently Secure -- At moderate risk of extinction, with relatively few populations or locations in the world, few individuals, and/or restricted range; or uncommon but not rare globally; may be rare in some parts of its range; possibly some cause for long-term concern due to declines or other factors. More information is needed to assign a single conservation status.

Did you know?
Goldenseal is highly valued for its medicinal properties and is now becoming more rare range-wide because it is being overcollected. Fortunately, it can also be grown in a nursery without disturbing wild populations.

State Ranking Justification [-]
There are 20 existing populations and about 10 historical records. It is not expected that many more populations will be found and that the threat from collection and habitat destruction may increase in the future.
