State Protection: Threatened

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 true abundance of this shrub is difficult to assess, because it is often hard to access every part of a maritime shrubland and not get covered in ticks! That is why most occurrences are known from road or trailsides where they are easily seen.

State Ranking Justification [-]
There are 13 existing populations but only 3 of them are large and extensive. Most of them are small with fewer than 10 plants. There are 5 additional historical locations and no additional plants have been found.
