Name:
Taxodium distichum - Nyssa biflora Tidal Swamp Forest Alliance
Reference:
NatureServe Biotics 2019
Description:
This alliance accommodates tidally flooded forests in lower, estuarine reaches of brownwater and blackwater rivers in the Outer Coastal Plain (tidewater) and also along estuarine shores. Flooding can be either lunar-tidal or wind-tidal and can be affected as well by riverine flooding events. The trees often have a stressed appearance, and the herbaceous layer usually is well-developed and more species-rich than in most non-tidal swamps, possibly as a result of the tidal nutrient input. Various combinations of <i>Nyssa biflora</i> and <i>Taxodium distichum</i> usually dominate the canopy. Some associations may also contain <i>Nyssa aquatica, Magnolia virginiana</i>, and/or <i>Pinus taeda</i> in the overstory. On blackwater rivers, <i>Nyssa aquatica</i> is often an indicator of a tidal condition, presumably because it requires the higher nutrients provided by tidal flooding. Other species common in tidal situations, such as <i>Lilaeopsis carolinensis, Morella cerifera, Osmunda cinnamomea, Osmunda regalis var. spectabilis, Peltandra virginica, Rosa palustris</i>, and <i>Thelypteris palustris var. pubescens</i>, are often common.
