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?
The specific epithet livida is a vague term that refers to the "effect of adding grey and black to the range of hues between blue and red," and was originally used to mean blue or leaden colored (Stearns 2004). This is probably in reference to the glaucous or light blue green color of Carex livida. So the common name, livid sedge, has nothing to do with this being an angry or furious plant.

State Ranking Justification [-]
There are five known populations and up to ten historical locations. This plant is found in open saturated areas of fens and bogs, a very specific and uncommon habitat type. Populations may be very local (i.e. common to a small area) but very rare across the entire habitat complex. A number of the known sites are within protected landscapes, but it still may be threatened by succession or hydrological changes.
