Ecological systems and subsytems (about):
TERRESTRIAL - TERRESTRIAL CULTURAL:
Cropland/field crops
An agricultural field planted in field crops such as alfalfa, wheat, timothy, and oats. This community includes hayfields that are rotated to pasture.
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.
TERRESTRIAL - OPEN UPLANDS:
Floodplain grassland* (guide)
A somewhat densely vegetated, tall grassland community that occurs on the floodplains along the upper reaches of larger confined rivers. This community occurs on relatively stable sand/gravel or cobble substrate that is often visible between the clump forming grasses. These floodplain shores and islands are typically broad and the soil is coarse and dry. These grasslands are subject to flooding and ice scour, but ice floes usually do not persist into spring as in riverside ice meadows.
PALUSTRINE - OPEN PEATLANDS:
Inland salt marsh* (guide)
A wetland that occurs on saline mudflats associated with inland salt springs. The mucky substrate is permanently saturated and seasonally flooded. Plant cover is sparse and the number of different kinds of plants is relatively low.
PALUSTRINE - OPEN PEATLANDS:
Medium fen (guide)
A wetland fed by water from springs and seeps. These waters are slightly acidic (pH values generally range from 4.5 to 6.5) and contain some dissolved minerals. Plant remains in these fens do not decompose rapidly and thus the plants in these fens usually grow on older, undecomposed plant parts of woody material, grasses, and mosses.
PALUSTRINE - OPEN PEATLANDS:
Rich sloping fen (guide)
A small, gently sloping wetland that occurs in a shallow depression on a slope composed of calcareous glacial deposits. Sloping fens are fed by small springs or groundwater seepage. Like other rich fens, their water sources have high concentrations of minerals and high pH values, generally from 6.0 to 7.8. They often have water flowing at the surface in small channels or rivulets.
PALUSTRINE - OPEN PEATLANDS:
Sedge meadow* (guide)
A wet meadow community that has organic soils (muck or fibrous peat). Soils are permanently saturated and seasonally flooded. The dominant herbs must be members of the sedge family, typically of the genus Carex.
PALUSTRINE - OPEN MINERAL SOIL WETLANDS:
Shallow emergent marsh (guide)
A marsh meadow community that occurs on soils that are permanently saturated and seasonally flooded. This marsh is better drained than a deep emergent marsh; water depths may range from 6 in to 3.3 ft (15 cm to 1 m) during flood stages, but the water level usually drops by mid to late summer and the soil is exposed during an average year.
TERRESTRIAL - OPEN UPLANDS:
Successional old field
A meadow dominated by forbs and grasses that occurs on sites that have been cleared and plowed (for farming or development), and then abandoned or only occasionally mowed.

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:
S3B
Vulnerable in New York - Vulnerable to disappearing from New York due to rarity or other factors (but not currently imperiled); typically 21 to 80 populations or locations in New York, few individuals, restricted range, few remaining acres (or miles of stream), and/or recent and widespread declines. (A migratory animal which occurs in New York only during the breeding season.)
Federal protection:
Not Listed
State protection:
Threatened
Listed as Threatened by New York State: likely to become Endangered in the foreseeable future. For animals, taking, importation, transportation, or possession is prohibited, except under license or permit. For plants, removal or damage without the consent of the landowner is prohibited.
SGCN:
NYNHP track status:
Y: Track all extant and selected historical EOs
