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?
If at first glance you see a tree with leaves and bark that looks like white oak (Quercus alba) in a swamp with red maple, then look closer to see if it is swamp white oak (Quercus bicolor). Swamp white oak leaves are hairy on the lower surface, whereas white oak lacks hair on the underside of the leaves.

State Ranking Justification [-]
There are very few occurrences of perched swamp white oak swamps statewide. Some perched swamp white oak swamps are too small to be protected by the New York State freshwater wetland regulations. A few documented occurrences have good viability and are protected on public land or private conservation land. This community has limited statewide distribution. 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 and alteration to the natural hydrology, and reduced protection regulations for isolated wetlands. This community has declined moderately from historical numbers likely correlated logging and development of the surrounding landscape.
