Coastal Oak-Holly Forest
Coastal oak-holly forest at Montauk Point State Park David M. Hunt
System: Terrestrial
SubSystem: Forested Uplands

State Protection: Not Listed
Federal Protection: Not Listed

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?
According to the USDA Forest Service's Silvics Manual (1990), "the "national champion" American holly (Ilex opaca), in the Congaree Swamp of South Carolina, is 30.2 m (99 ft) tall with a circumference of 248 cm (98 in), a trunk diameter of 79 cm (31 in), and a crown diameter of 12.2 m (40 ft)." American holly growth within its range on Long Island and other parts of New York is much more limited due to either persistent winds in a severe coastal climate, nutrient deficient soils, and/or periodic or extensive cold or low-growth periods at the northern limit of its range.

State Ranking Justification [-]
There is only one documented occurrence statewide and very few or no additional occurrences are suspected. The known occurrence has good viability and is largely protected on public and private conservation land. The community is restricted to the eastern extreme of the Coastal Lowlands and is concentrated on the Montauk Peninsula, a morainal plateau. While the acreage and extent of coastal oak-holly forest in New York may be increasing slightly, its condition is likely to be decreasing. Overall the community's trend is stable to slightly decreasing. Threats include invasion by exotic species, heavy deer browse, recreational overuse, and development pressures.
