Name:
Nyssa biflora - (Nyssa aquatica, Taxodium distichum) Tidal Forest
Reference:
Southeastern Ecology Working Gro...
Description:
This broadly defined association accommodates tidally flooded forests in lower, estuarine reaches of brownwater and blackwater rivers in the Outer Coastal Plain (tidewater), and also along estuarine shores. It may require subdivision as more information becomes available. Flooding of these environments 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 Nyssa biflora, Taxodium distichum, and Nyssa aquatica usually dominate the canopy. In addition, Liquidambar styraciflua may be present. On blackwater rivers, Nyssa aquatica is often an indicator of tidal condition, presumably because it requires the higher nutrients provided by tidal flooding. Other species common in tidal situations, such as Morella cerifera (= Myrica cerifera), Lilaeopsis carolinensis, Peltandra virginica, Thelypteris palustris var. pubescens, Osmunda regalis var. spectabilis, and Rosa palustris, are often common. Typical species of non-tidal swamps, such as Quercus lyrata, Carya aquatica, Quercus phellos, Smilax laurifolia, Ilex glabra, Lyonia lucida, Woodwardia virginica, Sphagnum spp., Chamaecyparis thyoides, Cyrilla racemiflora, and others, are absent.
