Name:
Pinus palustris / Serenoa repens / Aristida beyrichiana Woodland Alliance
Reference:
NatureServe Biotics 2019
Description:
This alliance accommodates mesic and wet-mesic (moist or saturated) Longleaf Pine woodlands and savannas found in the Southeastern Coastal Plain, from South Carolina to Mississippi and eastern Louisiana, including northern Florida. Related vegetation of other alliances is found to the north from southeastern Virginia into South Carolina, in the West Gulf Coastal Plain, and in southern Florida. Examples are dominated by <i>Pinus palustris</i>, with <i>Ilex glabra</i> and <i>Serenoa repens</i> as typical shrubs and <i>Aristida beyrichiana</i> (in contrast to <i>Aristida stricta</i> (<i>sensu stricto</i>) as a characteristic herb in many of the component associations. <i>Pinus serotina</i> may be present within its natural range (from southeastern Virginia south to panhandle Florida) but tends to be codominant only on the wettest, often organic soils. <i>Pinus elliottii var. elliottii</i> may be present or codominant within its natural range from South Carolina to eastern Louisiana. In parts of the range, <i>Pinus taeda</i> may also be present, and may represent a substantial component of the stand. In examples with longer fire return times, an understory of <i>Acer rubrum, Liquidambar styraciflua</i>, and <i>Morella cerifera</i> is likely to develop. Typical shrubs may include <i>Gaylussacia</i> spp., <i>Ilex coriacea, Ilex glabra, Ilex vomitoria, Morella cerifera, Osmanthus americanus var. americanus, Serenoa repens, Symplocos tinctoria</i>, and <i>Vaccinium</i> spp. Herbaceous diversity and cover are greater where the canopy and shrub layers are relatively open. Grasses usually make up the majority of total cover. Many soils contain a spodic horizon occasionally underlain by a clay hardpan, which additionally restricts drainage. Soils include Alfisols, Spodosols, and Ultisols. Sites vary in the presence or absence of a hardpan, in soil pH (range from 3.1-7.8), and in drainage.
