Livid Sedge Carex livida (Wahlenb.) Willd. |
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: G5
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 specific epithet livida is a vague term that refers to the "effect of adding grey and black to the range of hues between blue and red," and was originally used to mean blue or leaden colored (Stearns 2004). This is probably in reference to the glaucous or light blue green color of Carex livida. So the common name, livid sedge, has nothing to do with this being an angry or furious plant. |

| State Ranking Justification | [-] |
There are five known populations and up to ten historical locations. This plant is found in open saturated areas of fens and bogs, a very specific and uncommon habitat type. Populations may be very local (i.e. common to a small area) but very rare across the entire habitat complex. A number of the known sites are within protected landscapes, but it still may be threatened by succession or hydrological changes.
| Short-term Trends | [-] |
There are six populations which are currently known to be extant. There is no data available on the trends at these populations but at least four of these populations have large numbers of plants present. Therefore, short term trends are not clear but may indicate that this species is currently stable in New York.
| Long-term Trends | [-] |
There are six or more populations that have not been seen in recent years. The locality information for most of these populations is poor and surveys have not been conducted to these sites. It is unknown if these populations are still extant. All of the six extant populations were first discovered within the past 20 years. They were probably overlooked in the past. Overall, long term trends are unclear.
