State Rarity Rank: S3
A State Rarity Rank of S3 means: Typically 21 to 100 occurrences, limited acreage, or miles of stream 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?
Indian grass (Sorghastrum nutans) is a common grass of some rocky summit grasslands. Indian grass roots can grow to depths of seven feet, comprising two-thirds of the grass's total biomass! Indian grass is also the host plant of common wood nymph and wood satyr butterflies. These butterflies lay their eggs on Indian grass and the caterpillars eat the grass's leaves.

State Ranking Justification [-]
There are likely several hundred occurrences throughout upstate New York. Some of the documented occurrences have good viability and many are protected on public land or private conservation land, although most are relatively small and disturbed. This community has probably declined substantially from historical numbers and a few of the currently documented occurrences contain invasive plants and are threatened by fire suppression.
