Dark-green sedge Carex venusta Dewey |
Monocots |  Printer Friendly Version (PDF) |
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? The specific epithet venusta means beautiful or graceful (Stearn 2004). One of its common names is "graceful sedge." This sedge, like many plants that reach their north limit in New York, is restricted to Long Island. |

| State Ranking Justification | [-] |
Only known from a single site on Long Island. There are four other historical locations and two extirpated sites, all on Long Island. Long Island represents this species' northern range extent. There is very little suitable habitat remaining on Long Island, so the chances of finding new populations is low.
| Short-term Trends | [-] |
The one known extant population has been stable for at least 14 years. This is the only information known about how Carex venusta has been doing within the past 20 or so years and therefore short term trends are not clear but appears to be stable.
| Long-term Trends | [-] |
Two out of the seven populations ever known from New York are believed to be extirpated. There are an additional four populations which have not been seen since the early part of the 19 hundreds. It is unknown if these populations are still extant. The one extant population was first documented within the past 20 years. It might have been overlooked in the past as often happens with Carex species. Therefore, the long term trends indicate a decline.
