A0581 Pinus serotina Swamp Woodland Alliance

Type Concept Sentence: These saturated woodlands dominated by Pinus serotina, called pocosins or pond pine woodlands, occur on peats or organic-rich coarse sands in the southern Atlantic Coastal Plain of the United States.


Common (Translated Scientific) Name: Pond Pine Swamp Woodland Alliance

Colloquial Name: Pond Pine Swamp Woodland

Hierarchy Level:  Alliance

Type Concept: These are saturated woodlands dominated by Pinus serotina, often termed pocosins or pond pine woodlands. The canopy coverage of individual stands tends to vary in space and time from sparse woodland (less than 25% canopy cover), through woodland (25-60% canopy cover), to forest (more than 60% canopy cover). The average stand structure of most of these communities (with a fire regime of infrequent, high-intensity fire) is sparse woodland. Shrub densities can also be highly variable, with cover from 100% to less than 50%. Some common and typical shrubs (which vary from association to association) include Clethra alnifolia, Cyrilla racemiflora, Gaylussacia frondosa, Ilex coriacea, Ilex glabra, Kalmia carolina, Kalmia cuneata, Eubotrys racemosa, Lyonia ligustrina var. foliosiflora, Lyonia lucida, Morella caroliniensis, Morella cerifera, Persea palustris, Aronia arbutifolia, Smilax laurifolia, Toxicodendron vernix, Vaccinium formosum, and Viburnum nudum var. nudum. The three bay species Gordonia lasianthus, Persea palustris, and Magnolia virginiana are present in most examples, and Gordonia lasianthus is a codominant canopy species in some associations. This alliance can cover very large areas in Outer Coastal Plain peat domes and large peat-filled Carolina bays of southeastern Virginia, eastern North Carolina, and northeastern South Carolina, where it can form the landscape matrix in unbroken blocks of up to 100 square miles. In other landscapes, such as the Fall-line Sandhills of North Carolina, South Carolina, and Georgia, it occurs as relatively narrow bands along streams. Soils are generally peats or organic-rich coarse sands.

Diagnostic Characteristics: Saturated woodlands dominated by Pinus serotina with a significant evergreen shrub stratum.

Physiognomy and Structure: The canopy coverage of individual stands tends to vary in space and time from sparse woodland (less than 25% canopy cover), through woodland (25-60% canopy cover), to forest (more than 60% canopy cover). The average stand structure of most of these communities (with infrequent fire) is open woodland. Shrub densities can also be highly variable, with cover from 100% to less than 50%.

Floristics: These saturated woodlands are dominated by Pinus serotina, and often termed pocosins or pond pine woodlands. Some common and typical shrubs (variable from association to association) include Clethra alnifolia, Cyrilla racemiflora, Gaylussacia frondosa (= var. frondosa), Ilex coriacea, Ilex glabra, Kalmia carolina, Kalmia cuneata, Eubotrys racemosa (= Leucothoe racemosa), Lyonia ligustrina var. foliosiflora, Lyonia lucida, Morella caroliniensis (= Myrica heterophylla), Morella cerifera (= Myrica cerifera var. cerifera), Persea palustris, Aronia arbutifolia, Smilax laurifolia, Toxicodendron vernix, Vaccinium formosum, and Viburnum nudum var. nudum. The three bay species Gordonia lasianthus, Persea palustris, and Magnolia virginiana are present in most examples, and Gordonia lasianthus is a codominant canopy species in some associations.

Geographic Range: This alliance ranges from Virginia, Delaware, and possibly southern New Jersey, south to Florida and Alabama. It can cover very large areas in Outer Coastal Plain peat domes and large peat-filled Carolina bays of southeastern Virginia, eastern North Carolina, and northeastern South Carolina, where it can form the landscape matrix in unbroken blocks of up to 100 square miles. In other landscapes, such as the Fall-line Sandhills of North Carolina, South Carolina, and Georgia, and the Lake Wales Ridge in Florida, it occurs as relatively narrow bands along streams.
