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?
Dragon's-mouth orchid is considered rare throughout much of its range. This orchid is listed as rare in 17 of the 21 states and 6 of the 9 provinces where it is found. A number of populations are known from the northern Great Lakes. This orchid is difficult to see when it is not in bloom.

State Ranking Justification [-]
This pink orchid, once found throughout much of the state, is currently limited to some higher quality fen and bog communities. The total number of known populations is estimated at 20. There are a number of historical populations which have not been inventoried, but most of these are believed to be extirpated. Historically, there were a number of scattered populations on Long Island, but the last time this plant was reported from Long Island was in the mid-1980s. There are probably a few scattered stems still present there, but its long-term prognosis on Long Island is grim.
