State Rarity Rank: S2S3
A State Rarity Rank of S2S3 means: Imperiled or Vulnerable in New York - Very vulnerable to disappearing from New York, or vulnerable to becoming imperiled in New York, due to rarity or other factors; typically 6 to 80 populations or locations in New York, few individuals, restricted range, few remaining acres (or miles of stream), and/or recent and widespread 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?
Floodplain forests once covered wide stretches along rivers in New York, yet only a tiny fraction of this original extent remains today. Minerals and other nutrients carried in rivers are deposited here after floods; these forests were among the first to be cleared because they produce very productive farmland. Urban expansion is also common along rivers, and floodplain forests are often cleared for such expansion and altered by flood control structures. They serve as an important wildlife corridor between habitats and reduce flooding and excessive siltation downstream. Floodplain forests are one of the few places you can find the green dragon (Arisaema dracontium), a jack-in-the-pulpit plant relative.

State Ranking Justification [-]
There are several hundred occurrences statewide, although most are likely small and degraded. Some documented occurrences have good viability and many are protected on public land or private conservation land. This community is somewhat limited to the floodplains of large streams and rivers across the state, and includes a few very large, high quality, old-growth examples. The current trend of this community is probably stable for occurrences on public land and private conservation land, or declining slightly elsewhere due to moderate threats related to development pressure. This community has declined substantially from historical numbers likely correlated with past logging, agriculture, and other development.
