CEGL007703 Salix nigra - Acer (rubrum, saccharinum) / Alnus serrulata - Cephalanthus occidentalis Swamp Forest
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Black Willow - (Red Maple, Silver Maple) / Hazel Alder - Common Buttonbush Swamp Forest
Colloquial Name: Upper Coastal Plain-Interior Low Plateau Black Willow Pond Forest
Hierarchy Level: Association
Type Concept: This wetland willow forest association may occur on the margins of natural depression ponds, but it also includes vegetation on the margins of impoundment reservoirs. The canopy near the shoreline is dominated by Salix nigra. Other Salix species (including Salix caroliniana) may be present in some examples. Acer rubrum and Acer saccharinum are also important species. Cephalanthus occidentalis and Acer rubrum usually dominate the shrub layer. Alnus serrulata and Itea virginica are also present. Triadenum walteri grows on hummocks at the bases of trees and shrubs. Juncus effusus is often found in the herbaceous layer.

Classification Comments: The range of this Salix nigra pond association was adjusted, in part to resolve some issues with revisions to a previously overly generalized and overly well-distributed Salix nigra riparian association (CEGL002103). This concept (CEGL007703) may be too narrowly defined. Further review is needed, but it is a better choice for the vegetation along the Natchez Trace Parkway in any case.
At Arnold Air Force Base (Coffee and Franklin counties, Tennessee), this wetland community occurs along the border of Woods Reservoir. This community often grades into an herbaceous community dominated by Juncus effusus. Investigate merge with ~Salix nigra / (Cephalanthus occidentalis) Swamp Forest (CEGL004773)$$, a related type found to the south and west.

Floristics: In typical examples, the canopy is dominated by Salix nigra. Other Salix species (including Salix caroliniana) may be present in some examples. Acer rubrum and Acer saccharinum are also important species. Cephalanthus occidentalis and Acer rubrum usually dominate the shrub layer. Alnus serrulata and Itea virginica are also present. Triadenum walteri may grow on hummocks at the bases of trees and shrubs. Juncus effusus is often found in the herbaceous layer. The exotics Lonicera japonica and Rosa multiflora may be found in some examples.
Dynamics: Water levels fluctuate somewhat in examples of this association, typically being higher in the winter and spring, then drawing down in the summer and fall. Examples on the margins of impoundment reservoirs will have more stable water levels.
Environmental Description: This wetland willow forest association may occur on the margins of natural depression ponds, but it also includes vegetation on the margins of impoundment reservoirs.
Geographic Range: This type occurs in the Interior Low Plateau of Tennessee and also the adjacent Upper East Gulf Coastal Plain and Cumberlands/Southern Ridge and Valley. Its range includes Kentucky and Tennessee, as well as Alabama, Mississippi, and possibly Georgia.
