System: Terrestrial
SubSystem: Open 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?
What is calcareous? Calcareous communities occur around outcrops of calcium-rich bedrock such as limestone, dolomite, and marble.

State Ranking Justification [-]
There are several hundred occurrences statewide. Some documented occurrences have good viability and many are protected on public land or private conservation land. This community is limited to the calcareous regions of the state, and there are only a few high quality examples. The current trend of this community is probably stable for occurrences on public land, or declining slightly elsewhere due to moderate threats that include shoreline development, trampling by visitors, and invasive species.
