Ecological systems and subsytems (about):
TERRESTRIAL - FORESTED UPLANDS:
Coastal oak-heath forest (guide)
A low diversity, large patch to matrix, hardwood forest that typically occurs on dry, well-drained, sandy soils of glacial outwash plains or moraines of the Atlantic Coastal Plain. The forest is usually codominated by two or more species of scarlet oak, white oak, and black oak.
TERRESTRIAL - OPEN UPLANDS:
Hempstead Plains grassland (guide)
A tall grassland community that occurs on rolling outwash plains in west-central Long Island. This community occurs inland, beyond the influence of offshore winds and salt spray.
TERRESTRIAL - BARRENS AND WOODLANDS:
Pitch pine-heath barrens (guide)
A shrub-savanna community that occurs on well-drained, sandy or rocky soils. The most abundant tree is pitch pine and the shrublayer is dominated by heath shrubs.
TERRESTRIAL - FORESTED UPLANDS:
Pitch pine-oak forest (guide)
A mixed forest that typically occurs on well-drained, sandy soils of glacial outwash plains or moraines; it also occurs on thin, rocky soils of ridgetops. The dominant trees are pitch pine mixed with one or more of the following oaks: scarlet oak, white oak, red oak, or black oak.
TERRESTRIAL - BARRENS AND WOODLANDS:
Pitch pine-oak-heath woodland (guide)
A pine barrens community that occurs on well-drained, infertile, sandy soils. The structure of this community is intermediate between a shrub-savanna and a woodland. Pitch pine and white oak are the most abundant trees.
TERRESTRIAL - BARRENS AND WOODLANDS:
Pitch pine-scrub oak barrens (guide)
A shrub-savanna community that occurs on well-drained, sandy soils that have developed on sand dunes, glacial till, and outwash plains.

Conservation:
Global conservation status rank:
G3
Vulnerable globally - At 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.
State conservation status rank:
S1S2
Critically Imperiled or Imperiled in New York - Especially or very vulnerable to disappearing from New York due to rarity or other factors; typically 20 or fewer populations or locations in New York, very few individuals, very restricted range, few remaining acres (or miles of stream), and/or steep declines. More information is needed to assign either S1 or S2.
