Name:
Pinus (echinata, taeda) / Symplocos tinctoria - Morella cerifera - Vaccinium elliottii Forest
Reference:
NatureServe Biotics 2019
Description:
Natural forests occurring in the Coastal Plain west of the Mississippi River dominated by <i>Pinus echinata</i> and/or <i>Pinus taeda</i>. This forest is known from the West Gulf Coastal Plain of Arkansas, Louisiana, eastern Texas, and southeastern Oklahoma. This type is highly variable in terms of species composition and density due, in part, to occurrence across a wide range of site conditions ranging from dry-mesic to mesic. The canopy cover in stands can range from nearly pure pine of either <i>Pinus echinata</i> or <i>Pinus taeda</i> singly or in combination to approximately 25% hardwood species. Species composition tends to vary according to soil moisture with <i>Pinus echinata</i> attaining greater importance on drier sites, along with <i>Quercus stellata, Quercus falcata</i>. <i>Pinus taeda</i> and hardwoods such as <i>Nyssa sylvatica, Quercus alba, Liquidambar styraciflua</i>, and <i>Symplocos tinctoria</i> may be more important on mesic sites. The short-shrub stratum is sparse to patchy and includes canopy seedlings and <i>Symplocos tinctoria, Morella cerifera, Vaccinium elliottii, Viburnum dentatum, Cornus florida</i>, and <i>Callicarpa americana</i>. Vines may be sparse to moderately dense and include <i>Vitis rotundifolia, Gelsemium sempervirens, Toxicodendron radicans, Parthenocissus quinquefolia, Smilax pumila</i>, and <i>Smilax rotundifolia</i>. The herbaceous layer is sparse to moderately dense and includes <i>Chasmanthium sessiliflorum, Carex</i> spp., <i>Mitchella repens, Eupatorium perfoliatum</i>, and <i>Polystichum acrostichoides</i>. This forest typically occurs on Pleistocene terraces above the current floodplain but not on rugged topography. This community is commonly found on middle and lower slopes between uplands and streambottoms, but also on ridges and upper slopes. Soils are acidic and include silt loams, sandy loams underlain by clay, silty clays and clays. Caddo silt loam is a typical soil series.
