Patterned Peatland

System: Palustrine
SubSystem: Open 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?
Patterned peatlands are characterized by distinct microtopographic patterns that form strings and flarks parallel to the wetland basin's slope and perpendicular to the underlying groundwater flow. Strings are low elevated ridges of peat vegetated primarily by low shrubs, sedges and the occasional stunted tree. Flarks are low swales or hollows that are open, wet Sphagnum lawns with sedges and rushes as their representative species.

State Ranking Justification [-]
There are probably less than five occurrences of patterned peatland in New York where it reaches its southern limit in North America. Patterned peatlands are limited to the largest peatland areas in the Adirondacks where water flow is sufficient to form strings and flarks. Currently documented occurrences are protected on state land or private conservation land.
