Clustered Sedge
Carex cumulata (Bailey) Fern.
Carex cumulata Troy Weldy
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: S2S3
A State Rarity Rank of S2S3 means: Imperiled or Vulnerable in New York - Very vulnerable to disappearing from New York, or vulnerable to becoming imperiled in New York, due to rarity or other factors; typically 6 to 80 populations or locations in New York, few individuals, restricted range, few remaining acres (or miles of stream), and/or recent and widespread declines. More information is needed to assign a single conservation status.

Global Rarity Rank: G4?
A Global Rarity Rank of G4? means: Apparently Secure globally (most likely) - Conservation status is uncertain, but most likely uncommon 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 firm conservation status.

Did you know?
The specific name cumulata refers to the way the spikelets are piled up, like cumulus clouds, at the top of the stem. There are over 15 historical records for the species in New York and we expect to find more new populations as the search for this sedge continues.

State Ranking Justification [-]
The sedge is known from at least 15 populations where it is the dominant plant at several sites. There are several historical populations and lots of habitat that remains unchecked. As a plant that responds well to fire, populations may fluctuate widely depending on the current successional state of the immediate site. There are probably more populations present, particularly on the ridgetops of the Hudson Highlands, Shawangunk Mountains, and Taconic Ridge.
