Ecological systems and subsytems (about):
PALUSTRINE - FORESTED PEATLANDS:
Black spruce-tamarack bog (guide)
A conifer forest that occurs on acidic peatlands in cool, poorly drained depressions. The characteristic trees are black spruce and tamarack; in any one stand, either tree may be dominant, or they may be codominant. Canopy cover is quite variable, ranging from open canopy woodlands with as little as 20% cover of evenly spaced canopy trees to closed canopy forests with 80 to 90% cover.
PALUSTRINE - OPEN PEATLANDS:
Dwarf shrub bog* (guide)
A wetland usually fed by rainwater or mineral-poor groundwater and dominated by short, evergreen shrubs and peat mosses. The surface of the peatland is usually hummocky, with shrubs more common on the hummocks and peat moss throughout. The water in the bog is usually nutrient-poor and acidic.
PALUSTRINE - OPEN PEATLANDS:
Highbush blueberry bog thicket (guide)
A wetland usually fed by rainwater or mineral-poor groundwater and dominated by tall shrubs and peat mosses. The most abundant shrub is usually highbush blueberry. The water in the bog is usually nutrient-poor and acidic.
PALUSTRINE - OPEN PEATLANDS:
Inland poor fen (guide)
A wetland fed by acidic water from springs and seeps. Plant remains in these fens do not decompose rapidly and thus the plants in these fens usually grow on older, undecomposed plant parts of mostly sphagnum mosses.
PALUSTRINE - OPEN PEATLANDS:
Patterned peatland* (guide)
A large peatland whose surface forms a gentle slope with a mosaic of high and low areas (relative to water levels). These high and low areas occur as narrow or broad bands of vegetation and pools that extend perpendicular to the direction of water flow across the slope of the peatland. Peat moss (Sphagnum) is the most abundant plant.

Conservation:
Global conservation status rank:
G5
Secure globally - Common in the world; widespread and abundant (but may be rare in some parts of its range).
State conservation status rank:
S1
Critically Imperiled in New York - Especially vulnerable to disappearing from New York due to extreme rarity or other factors; typically 5 or fewer populations or locations in New York, very few individuals, very restricted range, very few remaining acres (or miles of stream), and/or very steep declines.
Federal protection:
Not Listed
State protection:
Not Listed
Not listed or protected by New York State.
SGCN:
