Classification of Vegetation Communities of Maryland: First Iteration
A Subset of the International Classification of Ecological
Concept: Young, or frequently disturbed, thickets of Salix nigra along rivers or the shores of artificial lakes, often with few to no other species present. Placement of this vegetation in shrublands is related to disturbance frequency, both natural and anthropogenic. This alliance is present in the following regions: Piedmont, Cumberland Plateau, Coastal Plain, Ozark Highlands, Boston Mountains, Ouachita Mountains, Osage Hills, and Arkansas Valley.
Comments: Now (2000-05-17) includes the former Salix nigra Woodland (CEGL003731). Later successional and/or more speciose communities with Salix nigra as a dominant will be found in I.B.2.N.d Salix nigra Temporarily Flooded Forest Alliance (A.297).
Range: This alliance is present in the following regions: Piedmont, Cumberland Plateau, Coastal Plain, Ozark Highlands, Boston Mountains, Ouachita Mountains, Arkansas Valley, Mississippi River Alluvial Plain, and Florida Peninsula. It is found in Alabama, Arkansas, Florida, Georgia, Kentucky, Louisiana, Mississippi, North Carolina, Oklahoma, South Carolina, Tennessee, Maryland, Maine, New Hampshire, Vermont, Virginia, and West Virginia, and in Ontario, Canada, and possibly in Texas (?) and Ohio (?).

SALIX NIGRA TEMPORARILY FLOODED SHRUBLAND

Black Willow Riverbank Shrubland G4? (01-09-19)
Ecological Group (SCS;MCS): Southeastern Coastal Plain Riverfront and Levee Forests and Shrublands (385-30; 184.108.40.206)
Concept: This broadly defined type represents vegetation dominated by scrubby forms of Salix nigra across the southeastern and northeastern United States, and possibly into Canada. Stature and closure may vary depending on disturbance. Additional types may be developed as more information becomes available.
Comments: This type conceptually includes communities formerly treated as woodlands [see the archived Salix nigra Woodland (CEGL003731)].
Range: This is a potentially wide-ranging association found throughout the southeastern and eastern United States, and possibly into Canada. This broadly defined association is found from the Ozarks and Interior Low Plateau, south to the West and East Gulf coastal plains and Florida Peninsula, east to the Atlantic Coastal Plain (excluding the Southern Blue Ridge) and north into the Central Appalachians and Northern Piedmont.
