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

Did you know?
Even though the common name is long-beaked beakrush this species is truly a sedge and not a rush. The specific epithet "scirpoides" means Scirpus like. Scirpus is another genus in the sedge family (Fernald 1970).

State Ranking Justification [-]
There are 33 known extant populations. There are 3 populations which have not been seen in over 65 years. One population has been extirpated. 24 of the known extant populations are of excellent to good quality (ranked A or B). Most of the populations are small in terms of acreage. The habitat that is required for this species is very specific and extremely limited in New York. Most of the populations are clustered together and all but one are known from eastern Suffolk County, Long Island.
