State Protection: Endangered
listed species are those with: 1) 5 or fewer extant sites, or 2) fewer than 1,000 individuals, or 3) restricted to fewer than 4 U.S.G.S. 7 minute topographical maps, or 4) species listed as endangered by U.S. Department of Interior.

Federal Protection: Not Listed

State Rarity Rank: S1
A State Rarity Rank of S1 means: This plant is endangered/critically imperiled in New York because of extreme rarity (typically 5 or fewer populations or very few remaining individuals) or is extremely vulnerable to extirpation from New York due to biological factors.

Global Rarity Rank: G5
A Global Rarity Rank of G5 means: This species is demonstrably secure globally, though it may be quite rare in parts of its range, especially at the periphery.

Did you know?
Vaginata means sheathed (Fernald 1970), which probably refers to the lower leaves which are long sheathing and lack blades. Carex vaginata is circumpolar in distribution and occurs around the world in the northern regions.

State Ranking Justification [-]
There is only a single known population with five historical locations. This is a plant of calcareous swamps, a limited and rare community type. New York is also this species' southern range limit. This sedge should be sought in other calcareous swamps similar to Bergen, Bonaparte, and Lisbon Swamps.
