Name: Nyssa aquatica Swamp Forest Alliance
Reference: NatureServe Biotics 2019
Description: This alliance encompasses semipermanently flooded forested riverine swamps dominated by <i>Nyssa aquatica</i>. Other canopy and subcanopy species may include <i>Carya aquatica, Fraxinus caroliniana, Fraxinus profunda, Nyssa biflora, Planera aquatica, Populus heterophylla</i>, and <i>Quercus lyrata</i>. Shrubs and herbs are typically limited to tree bases, fallen logs, and other elevated places in the stand. <i>Itea virginica</i> is often the only shrub present. Herbaceous species may be absent and often are sparse. Species present can include <i>Asclepias perennis, Boehmeria cylindrica, Carex glaucescens, Carex joorii, Justicia ovata, Leersia lenticularis, Onoclea sensibilis, Phanopyrum gymnocarpon, Pluchea camphorata, Proserpinaca pectinata, Rudbeckia laciniata, Sagittaria latifolia, Saururus cernuus, Triadenum walteri</i>, and others. Associations in this alliance occur in backwater sloughs, low wet flats, swales and backswamps, and along blackwater streams and other alluvial settings. Surface water is present throughout the growing season in most years. Forests in this alliance occur virtually throughout the Atlantic and Gulf coastal plains and the Mississippi River Alluvial Plain within the range of <i>Nyssa aquatica</i>, and in the Arkansas River Valley; also reported from the Mobile and Tensaw rivers in Alabama.
