Monocots
Carex craweii David Werier
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: 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 crawei is named after Ithamar Bingham Crawe, 1792-1847, who discovered this plant (Fernald 1970). Valcour Island, located in Lake Champlain near Plattsburgh, is the best place in New York to find Carex crawei.

State Ranking Justification [-]
There are nine known populations, but three of these only have a few plants. The largest populations have over a 10,000 stems. These are primarily restricted to limestone pavement areas and other types of sites associated with calcareous bedrock. This type of habitat is very limiting. Some of these sites face battles with various invasive species. There are a few historical sites and the possibility that this plant has been overlooked. More survey work is needed at the sites with small populations reported, as well as at sites where habitat conditions seem suitable.
