New York Natural Heritage Program
Slender Nutrush
Scleria minor W. Stone
Monocots
Family: Sedge Family (Cyperaceae)

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: 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?
In New York, slender nutrush was only ever known around the Islip-Oakdale area on Long Island and one wetland in Nassau County that was drained. It is presently known from the Islip area, but has not been found anywhere else on Long Island.

State Ranking Justification [-]
There are two existing populations within a short distance of each other on Central Long Island, but neither of the populations has been seen in over 18 years. The plants may still be in the seed bank waiting for the right disturbance. This plant has always been rare in New York with only four other historical occurrences.
