Carex davisii Schwein. & Torr.
Monocots
Carex davisii Stephen M. Young
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: S2
A State Rarity Rank of S2 means: This plant is threatened/imperiled in New York because of rarity (typically 6-20 populations or few remaining individuals) or is 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 davisii is named after Emerson Davis who was alive from 1798-1866 and was an "amateur student of Carex" (Fernald 1970).

State Ranking Justification [-]
There are currently twelve known populations and at least a dozen historical sites. At one time, it was thought this sedge was mostly restricted to woodland edges near the freshwater high tide mark along the Hudson River. Recently, additional populations have been found at various inland sites. As more people become familar with this plant, we should expect to find more populations. The additions of these new populations may represent a positive trend for a species that is expanding its range, or it may simply be another sedge that has been grossly overlooked.
