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: G5T5
A Global Rarity Rank of G5T5 means: Secure globally - Both the species as a whole and the subspecies/variety are common in the world; widespread and abundant (but may be rare in some parts of its range).


Did you know?
Saltmarsh aster is the only native aster in New York which is an annual (Brouillet et al. 2006). The scientific name subulatum means awl-shaped (Fernald 1970) and is perhaps in reference to the shape of the involucral bracts.

State Ranking Justification [-]
There are currently 13 known extant populations. At least an additonal 18 populations have not been seen in recent years and are considered historical. One population is believed to have been extirpated due to habitat destruction. Some of the historical populations occur in and around the New York City metropolitan area and have likely been extirpated. Overall, the habitat for this species is limited in New York and much of this habitat has been damaged or destroyed.
