Floodplain Forests
General Wet Hardwood Forests
Habitat Overview This habitat includes river and stream bottomlands that support stands of hydrophilic species of hardwood trees. Upland depression swamps sharing the same species -- particularly Willow Oak -- are also included, as are non-riverine stands of wet hardwoods in the Coastal Plain. The soils of these habitats are frequently flooded and remain wet for prolonged periods following withdrawal of flood waters. However, they are not permanently inundated. This is the most generalized of the habitats associated with floodplains, occurring in at least two of the state's physiographic provinces. Most of these habitats in the Piedmont and Low Mountains are associated with brownwater habitats and are fairly rich in nutrients. In the Coastal Plain, both brownwater and blackwater forests are included.

Determining Species include several hardwood tree species that are tolerant of a wide range of nutrient, pH, and hydrological conditions. A few herbaceous species that occur widely across the state in floodplain forests are also members of this group. Species that require special soil or hydrological conditions, however, are treated in other habitats.

Animal species mainly comprise herbivores that are either obligates on the plant species belonging to this habitat or that are polyphagous on several of them. In some cases, the host plants are unknown but the species show a strong fidelity to bottomland hardwood forests.
