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: Apparently Secure globally (most likely) - Conservation status is uncertain, but most likely uncommon in the world but not rare; usually widespread, but 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 firm conservation status.


Did you know?
There is little doubt about this plant's watery habitat preference with a species name like inundata.

State Ranking Justification [-]
There are three existing populations and two of them consist of more than one hydrologically connected pond. The third population is less than 100 plants. All populations are within parkland. There are five historical populations from the early and mid-1900s which have been resurveyed but no plants have been found. They are not considered extirpated because of the fluctuating nature of the populations.
