Name:
Liquidambar styraciflua - Quercus laurifolia - (Pinus taeda) / Arundinaria gigantea / Carex abscondita Floodplain Forest
Reference:
NatureServe Biotics 2019
Description:
These forests occur on somewhat poorly drained to moderately well-drained silt loam soils of ridges of associated river floodplains in the southern Atlantic Coastal Plain. These are temporarily flooded sites with an annual probability of flooding of 100% but with the water table well below the soil surface throughout the growing season in most years. At the Congaree National Park (South Carolina), this community type occurs in two phases: one with an emergent canopy of large <i>Pinus taeda</i> trees, and the other without the emergent canopy. Coverage by <i>Pinus taeda</i> in the <i>Pinus taeda</i> phase ranges from 10% to greater than 60%. The closed canopy of stands of this type is codominated by <i>Liquidambar styraciflua</i> with <i>Quercus</i> spp., especially <i>Quercus nigra</i> and <i>Quercus laurifolia</i>, and possibly by <i>Quercus phellos</i>. Other species typical in this stratum include <i>Ulmus alata, Ulmus americana, Fraxinus americana, Quercus pagoda, Quercus michauxii, Quercus shumardii</i>, and <i>Acer rubrum</i>. The well-developed subcanopy is dominated by <i>Carpinus caroliniana</i> and <i>Ilex opaca</i>. Canopy species are present in this stratum as well, as are <i>Nyssa sylvatica, Ilex decidua, Diospyros virginiana, Celtis laevigata, Carya ovata, Morus rubra</i>, and likely other species. <i>Arundinaria gigantea</i> and <i>Asimina triloba</i> dominate the shrub stratum. The herbaceous layer ranges from moderate to fairly dense. Typical species include <i>Carex abscondita, Boehmeria cylindrica, Mitchella repens, Botrychium dissectum, Carex intumescens, Carex lupulina, Carex retroflexa, Asplenium platyneuron, Carex alata, Carex debilis, Ruellia caroliniensis, Elephantopus tomentosus, Leersia virginica, Dichanthelium boscii, Lobelia cardinalis, Sabatia angularis</i>, and others. This forest type is documented in the Mid-Atlantic Coastal Plain, but is possible in adjacent regions; global distribution needs assessment.
