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.

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.

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 genus name to Eleocharis comes from the Greek "elos" for marsh and "charis" for grace. With more herbarium work and field study we might find that this little Eleocharis graces many more of the marshes in our state. 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 three existing populations but only one of them contained over 100 plants. One other population was on a river sandbar and may be gone and four other populations were composed of only a few plants. There are about 10 historical records from upstate New York and the Adirondacks which have not been checked.
