System: Terrestrial
SubSystem: Forested Uplands

State Protection: Not Listed
Federal Protection: Not Listed

State Rarity Rank: S2
A State Rarity Rank of S2 means: Typically 6 to 20 occurrences, few remaining individuals, acres, or miles of stream, or factors demonstrably make it very vulnerable in New York State.

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?
American chestnut was a common canopy species in Allegheny Oak Forest prior to the chestnut blight. This blight is caused by a fungal infection introduced from Asia in the late 1800's. Its spread has eliminated American Chestnut from the canopy of eastern North American forests. The species persists as sapling sprouts from the tree bases that fall prey to the fungus before the tree can mature and reproduce, beginning the resprout cycle over and over again.

State Ranking Justification [-]
There are currently fewer than ten sites known in New York with an estimate of several hundred to a couple thousand acres statewide. A few documented occurrences have good viability and several are protected on public land or private conservation land. This community has a limited statewide distribution and includes a few large, high quality examples. The current trend of this community is probably stable for occurences on public land, or declining slightly elsewhere due to moderate threats related to development pressure and unsustainable logging.
