Wiegand's Sedge Carex wiegandii Mackenzie |
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? Carex wiegandii is named in honor of Karl McKay Wiegand (1873-1942), a major botanist from New York (Fernald 1970). Wiegand worked at Cornell University and the herbarium at Cornell is known as the Wiegand Herbarium. |

| State Ranking Justification | [-] |
There are four known sites and only one historical location. These sites are in remote Adirondack and Tug Hill peatlands that face few to no threats and are within well-protected landscapes. This is a difficult to identify and difficult to locate sedge that may be overlooked. Other bog areas within the Adirondacks and Tug Hill should be surveyed with this sedge in mind.
| Short-term Trends | [-] |
Short term trends can not be assessed for populations in New York because there is not enough data available. Still, it is known that two populations have remained extant over the past twenty to thirty years.
| Long-term Trends | [-] |
There is very little historical data regarding C. wiegandii in New York. Therefore, long term trends are unknown.
