Coastal Plain Atlantic White Cedar Swamp
Coastal Plain Atlantic White Cedar Swamp at Quogue Wetlands Gregory J. Edinger
System: Palustrine
SubSystem: Forested Peatlands

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: 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?
Atlantic white cedar can only colonize open boggy areas because its seedlings do not grow well in the shade. Fires, storms, or logging, may repeatedly level such a forest, but this tree will return again and again. Indeed, without catastrophies to repeat the process of invasion, red maple and black gum will in turn, become invaders within the swamp. The red maple invasion has already begun, but it is a gradual process. The seedlings of Atlantic white cedar, like pitch pine, will eventually fail to grow in the deep shade. Still, only if there are several centuries without a disturbance (a rare thing in nature), will there be a complete change.

State Ranking Justification [-]
There are very few occurrences of coastal plain Atlantic white cedar swamps statewide. A few documented occurrences have good viability and are protected on public land or private conservation land. This natural community is still declining somewhat due to threats related to development pressure and alteration to the natural hydrology. This community has declined from historical numbers likely correlated with past logging of white cedar and the conversion of swamps to commercial cranberry bogs that were subsequently abandoned.
