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: G4
A Global Rarity Rank of G4 means: Apparently secure globally, though it may be quite rare in parts of its range, especially at the periphery.


Did you know?
There are only two species of Liriodendron in the world. Both are in the magnolia family and have flowers that resemble tulips. One is characteristic of oak-tulip tree forests in the eastern U.S (Liriodendron tulipifera), the other is native to China (Liriodendron chinense). In these eastern U.S. forests, tulip trees and white pine are the largest trees. They can grow rather tall (60 to 90 feet and sometimes up to 150 feet) and very rapidly. Due to this quality, Native Americans made dugout canoes from tulip tree trunks.

State Ranking Justification [-]
There are less than one hundred occurrences statewide. A few documented occurrences have good viability and several are protected on public land or private conservation land. This community is somewhat limited to the Lower Hudson Valley and western Long Island, and most examples are fragmented and disturbed. 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. This community has declined substantially from historical numbers likely correlated with past logging, agriculture, and other development.
