Family: Sedge Family (Cyperaceae)

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?
The name chordorrhiza means with cord-like roots (Fernald 1970). This is probably in reference to the vegetative stems which become prostrate and root at the nodes. As they become buried by mosses and other plants they appear like rhizomes (Reznicek and Catling 2002).

State Ranking Justification [-]
There are at least fourteen known populations and equally as many historical locations. Most of these are located within Oswego County where many peatland habitats exist. Other populations are present in Warren, Wyoming, and Cattaraugus Counties. This plant is typically found in higher quality inland poor fens and similar habitats. These are relatively well protected, although succession is a possible threat. Many of the populations are large, including some with upwards of 10,000 culms. This sedge is relatively easy to identify, therefore it is not overlooked often.
