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.
