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: 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?
This species is named for Edwin James (1797-1861) who discovered this plant. Carex jamesii is part of a complex of three species, the other two, C. juniperorum and C. timida, were only recently described (1993 and 2001 respectively).

State Ranking Justification [-]
There are 13 known populations in New York, and at least an additional eight historical sites. This sedge is limited to calcareous areas of central/western New York. It does appear to be threatened by invasive species and does not respond well to logging as other sedges are able to do.
