Family: Aster Family (Asteraceae)

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: G5T5?
A Global Rarity Rank of G5T5? means: Secure globally (most likely) - Conservation status of the subspecies/variety is uncertain, but is most likely common in the world; widespread and abundant (but may be rare in some parts of its range). More information is needed to assign a firm conservation status. (The species as a whole is common globally.)

Did you know?
This plant may be overlooked because it is shorter and more narrow than the common variety of seaside goldenrod and may be hidden among the taller saltmarsh grasses and rushes. It was rediscovered on Long Island in 1992 after not being seen there for 70 years (Lamont 1994).

State Ranking Justification [-]
There are three existing populations, of several hundred plants each, but these are threatened by the expansion of nearby Phragmites populations. There are seven historical populations known from the late 1800s and early 1900s that have not been resurveyed and two additional populations that are considered extirpated.
