State Rarity Rank: S1
A State Rarity Rank of S1 means: Typically 5 or fewer occurrences, very few remaining individuals, acres, or miles of stream, or some factor of its biology makes it especially vulnerable in New York State.

Global Rarity Rank: G2G3
A Global Rarity Rank of G2G3 means: Imperiled or Vulnerable globally - At high or moderate risk of extinction due to rarity or other factors; typically 80 or fewer populations or locations in the world, 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.


Did you know?
From Stack (1989): "Early 19th century maps and photos show that nearly the entire eastern end of Long Island was once covered with tallgrass prairie-like vegetation. The grasslands supported large herds of grazing animals driven there from as far away as East Hampton to summer on the rich pasture. Annual burning in addition to cattle and sheep grazing kept woody species like bayberry, sumac, cherry, and locust from establising in the community. There are records that suggest that this (burning) was a practice learned from the previous inhabitants of the area, the Montauk Indians."

State Ranking Justification [-]
Some of the documented occurrences of this community have good viability and several are protected on public or private conservation land. The community is restricted to the Coastal Lowlands ecozone of eastern Long Island in Suffolk County and is found primarily on the South Fork. The trend for the community is declining due to significant threats from development, fire suppression, and trampling.
