Carya laciniosa (Michx. f.) G. Don
Dicots

Habitat [-]
A tree typically found in the rich alluvium of floodplains, but also in rich mesic soil along riverbanks and marshes. In some areas it can form pure stands, but usually is mixed with other floodplain species (New York Natural Heritage Program 2005). Moist, rich bottomlands and floodplains (Rhoads and Block 2000). Rich bottomlands, along creeks, and in open cedar glades (Flora of North America 1997). Flood plains (Gleason and Cronquist 1991). Riverbanks and rich floodplain woods (Voss 1985). Rich woods and bottoms (Fernald 1970).

Associated Ecological Communities [-]
  • Beech-maple mesic forest
    A hardwood forest with sugar maple and American beech codominant. This is a broadly defined community type with several variants. These forests occur on moist, well-drained, usually acid soils. Common associates are yellow birch, white ash, hop hornbeam, and red maple.
  • Floodplain forest
    A hardwood forest that occurs on mineral soils on low terraces of river floodplains and river deltas. These sites are characterized by their flood regime; low areas are annually flooded in spring, and high areas are flooded irregularly.
  • Silver maple-ash swamp
    A hardwood basin swamp that typically occurs in poorly-drained depressions or along the borders of large lakes, and less frequently in poorly drained soils along rivers. These sites are characterized by uniformly wet conditions with minimal seasonal fluctuations in water levels. The dominant trees are usually silver maple and green ash.
