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: S1S2
A State Rarity Rank of S1S2 means: Critically Imperiled or Imperiled in New York - Especially or very vulnerable to disappearing from New York due to rarity or other factors; typically 20 or fewer populations or locations in New York, very few individuals, very restricted range, few remaining acres (or miles of stream), and/or steep declines. More information is needed to assign a single conservation status.

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?
The specific epithet mitchelliana was named in honor of Eisha Mitchell who lived from 1793 to 1857 (Fernald 1970).

State Ranking Justification [-]
There are only five known populations on Long Island, but more populations are suspected. A handful of historical locations still need to be surveyed. This is a plant of coastal wetlands that is confused with Carex crinita and Carex gynandra. Range-wide fewer than 100 populations are known, all restricted to the Atlantic and Gulf Coasts. This plant is threatened by invasive species, particularly Phragmites, and habitat alterations.
