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: S1S2
A State Rarity Rank of S1S2 means: Critically Imperiled or Imperiled in New York - Especially or very vulnerable to disappearing from New York due to rarity or other factors; typically 20 or fewer populations or locations in New York, very few individuals, very restricted range, few remaining acres (or miles of stream), and/or steep declines. More information is needed to assign a single conservation status.

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.

Although Georgia Bulrush is named after the state of Georgia it is known from as far north as Prince Edward Island, Canada (Harper 1900, Whittemore and Schuyler 2002).

State Ranking Justification [-]
Scirpus georgianus is close to the northern part of its range in New York. It is only known to occur in widely scattered disjunct populations in the northern part of its range even though there is ample available habitat (Whittemore and Schuyler 2002, New York Natural Heritage Program 2007). There are currently 6 known extant populations although 3 of these have not been seen in nearly 20 years. There are 14 populations which have not been seen in at least 30 years and are considered historical. Additionally, 3 populations are believed to have become extirpated. Some of the historical occurrences may be based on misidentified specimens as the synonym S. atrovirens var. georgianus was long mis-applied to the common S. hattorianus.
