State Rarity Rank: S1S2
A State Rarity Rank of S1S2 means: Critically Imperiled or Imperiled in New York - Especially or very vulnerable to disappearing from New York due to rarity or other factors; typically 20 or fewer populations or locations in New York, very few individuals, very restricted range, few remaining acres (or miles of stream), and/or steep declines. More information is needed to assign a single conservation status.

Global Rarity Rank: G3G4
A Global Rarity Rank of G3G4 means: Vulnerable globally, or Apparently Secure -- At moderate risk of extinction, with relatively few populations or locations in the world, few individuals, and/or restricted range; or uncommon but not rare globally; 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.

Did you know?
Poison sumac grows in rich shrub fens. Like poison ivy and poison oak, poison sumac contains the chemical urushiol, which can cause a skin rash upon contact by sensitive people. If ingested or inhaled, the urushiols attack the mucous membranes of mouth, nose, and intestines and can cause death. However, the fruit is non-toxic to, and is commonly eaten by, birds and other animals.

State Ranking Justification [-]
There are about one hundred occurrences statewide. Some documented occurrences have good viability and several are protected on public land or private conservation land. This community is limited to the calcareous areas of the state and is restricted to wetlands that gain most of their moisture from underground sources that flow through calcareous substrates. There are a few large, high quality examples. Most sites are small and some are very disturbed. The current trend of this community is probably stable for occurrences on public land, or declining slightly elsewhere due to moderate threats related to development pressure or alteration to the natural hydrology.
