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: G5T4T5
A Global Rarity Rank of G5T4T5 means: Apparently or Demonstrably Secure globally - The subspecies/variety is uncommon to common in the world, but not rare; usually widespread, but may be rare in some parts of its range; possibly some cause for long-term concern due to declines or other factors. More information is needed to assign a single conservation status. (The species as a whole is common globally.)

Did you know?
The genus named Eupatorium honors Mithridates Eupator, a ruler of the region Pontus on the southern edge of the Black Sea, who reportedly used a species of the genus in medicine (Fernald 1970). The species and variety name refer to the leaves which resemble a species of the European hyssop, and have larger and more ragged teeth than the typical variety of this species.

State Ranking Justification [-]
There are 10 existing populations but only three of them are in good to excellent condition. The others are small and may not have good long-term viability. There are four historical occurrences.
