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: G4G5
A Global Rarity Rank of G4G5 means: Apparently or Demonstrably Secure globally - Uncommon to common in the world, but not rare; usually widespread, but may be rare in some parts of its range; possibly some cause for long-term concern due to declines or other factors. More information is needed to assign a single conservation status.


Did you know?
The specific epithet, striatula, means "with fine longitudinal lines" (Fernald 1970).

State Ranking Justification [-]
There is only one known population and three historical locations. As a plant at the northern edge of its range, this sedge has likely always been rare in New York. The one known population only has 20 plants. Surveys in the lower Hudson Valley should target this plant to determine if more populations are present.
