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: 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?
Woodland bluegrass was first collected in New York in 1848 at Niagara Falls by William Starling Sullivant, the foremost American bryologist of the 19th century.

State Ranking Justification [-]
There are five known populations and at least nine historical populations. Many of these populations are small. As a woodland grass in relatively common habitats, this plant may be overlooked. More survey work that focuses on finding this plant are needed. This species may benefit from a predictive distribution model.
