monocots |  Printer Friendly Version (PDF) |
Family: Sedge Family (Cyperaceae)
State Protection: Endangered Species 
This level of state protection means: 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 ½ 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: 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? This is the only Eleocharis species in New York with a tall square stem, thus the species name. The genus name Eleocharis comes from the Greek "elos" for marsh and "charis" for grace. This and many other Eleocharis species are important wildlife food for wetland birds and other animals. You can often see damselflies and dragonflies perching on the tops of the stems. |

| State Ranking Justification |
| There are four existing populations but only one of them is large. The three other populations are small or threatened by development. There are about 10 historical populations, some of which need to be checked and some are considered extirpated. |
