Pinus echinata - Quercus stellata - Quercus falcata - Carya texana Woodland
» more details
accession code: urn:lsid:vegbank.org:commConcept:35987-{6775CD29-D8F7-48B0-90E9-813F6FB82F8B}
NatureServe Biotics 2019  2 This pine-oak woodland occurs on dry, acidic, loamy to clayey uplands in the West Gulf Coastal Plain of Louisiana and Texas. The canopy is dominated by <i>Pinus echinata</i> and <i>Quercus stellata</i>. Other important overstory trees include <i>Quercus falcata, Carya texana</i>, and <i>Carya tomentosa</i>. The understory tends to be quite open and herb-dominated, and may be quite species-rich. Most of the former examples of this woodland have been fire-suppressed resulting in more closed forests, in which <i>Pinus taeda</i> has become an important overstory tree.

Liquidambar styraciflua - Acer rubrum - (Nyssa biflora) / Woodwardia virginica Floodplain Forest
» more details
accession code: urn:lsid:vegbank.org:commConcept:36033-{EBCBADDB-CC67-4CD2-938E-59C03DF822C6}
NatureServe Biotics 2019  2 This community occurs as small (less than one acre) depressions scattered in low oak flats in the Outer Coastal Plain of southeastern South Carolina, northeastern Florida, and adjacent Georgia. <i>Liquidambar styraciflua</i> and <i>Acer rubrum</i> are the constant dominants, sometimes with an admixture of <i>Nyssa biflora</i>. Scattered shrubs may occur, usually on logs, including <i>Itea virginica, Vaccinium formosum</i>, and <i>Eubotrys racemosa</i>. <i>Woodwardia areolata</i> dominates the herb layer, at least in the marginal portions of the pond where water is ponded more shallowly and for shorter periods of time; deeper ponds have a ring of <i>Woodwardia</i>, while shallower ponds are <i>Woodwardia</i>-dominated all the way across.

accession code: urn:lsid:vegbank.org:commConcept:36053-{BFB6D315-E8C5-4BDF-86F5-8829FAD7B687}
NatureServe Biotics 2019  2 This community is found along margins and along broad intermittent drainages associated with Catahoula Barrens in the West Gulf Coastal Plain of eastern Texas. <i>Quercus stellata</i> is the dominant tree; others may include <i>Carya texana</i> and <i>Quercus marilandica</i>. The shrub stratum is now currently dense but was probably formerly open because of fire and includes <i>Ilex vomitoria, Forestiera ligustrina, Vaccinium arboreum, Crataegus marshallii, Crataegus spathulata, Crataegus brachyacantha, Gelsemium sempervirens</i>, and <i>Cissus trifoliata</i>. The herb stratum is sparse to dense becoming increasingly sparse in the absence of fire and the consequent build-up of hardwood leaf litter. The herb layer is dominated by <i>Chasmanthium sessiliflorum</i>. <i>Ranunculus fascicularis</i> may be abundant in the springtime.

Quercus michauxii - Quercus nigra - Pinus taeda / Carpinus caroliniana Floodplain Forest

accession code: urn:lsid:vegbank.org:commConcept:36084-{72D4659D-010C-4B04-983E-B863F4BF8E89}
NatureServe Biotics 2019  2 This is an association that was once prevalent along intermediate streams throughout much of the West Gulf Coastal Plain of west-central Louisiana within the range of <i>Magnolia grandiflora</i>. Typical canopy species include <i>Quercus michauxii, Quercus nigra, Pinus taeda, Magnolia grandiflora, Quercus pagoda, Magnolia virginiana, Acer rubrum</i>, and <i>Quercus laurifolia</i>. <i>Taxodium distichum</i> and <i>Nyssa aquatica</i> are present in depressional inclusions in the floodplain. The midstory is dominated by <i>Carpinus caroliniana</i>. <i>Toxicodendron radicans</i> is a common woody vine. Herb layer species include numerous <i>Carex</i> spp., <i>Cardamine bulbosa, Rudbeckia laciniata var. laciniata, Phanopyrum gymnocarpon</i>, and <i>Solidago patula var. strictula</i>. This type occurs in the floodplains of small to intermediate streams on acidic silty to sandy substrates, in the West Gulf Coastal Plain of central Louisiana. Characteristic examples occur on Loving Creek (Rapides Parish, Louisiana).

Carya illinoinensis - Celtis laevigata - Ulmus (americana, crassifolia) Mississippi River Floodplain Forest
» more details
accession code: urn:lsid:vegbank.org:commConcept:36095-{B3B1FAA8-B782-47AB-AFF0-93B2E6667A0C}
NatureServe Biotics 2019  2 This is a bottomland forest of upper terraces in the Mississippi River Alluvial Plain of Arkansas, Louisiana, Mississippi, and Tennessee and possibly the adjacent West Gulf Coastal Plain. More information is to be provided by Susan Carr and Tom Foti. Forest stands dominated by the nominal species (<i>Carya illinoinensis, Celtis laevigata, Ulmus americana</i>) have been observed in Shelby Forest State Park, Shelby County, Tennessee (234An). The possible occurrence of this or related vegetation in the adjacent West Gulf Coastal Plain needs to be confirmed.

Quercus phellos - Quercus nigra - Liquidambar styraciflua Mississippi River Floodplain Forest
» more details
accession code: urn:lsid:vegbank.org:commConcept:36098-{21B721BA-9E60-4CBD-8E92-766D05B27A30}
NatureServe Biotics 2019  2 This association covers large floodplain forests of the Mississippi River Alluvial Plain, Upper East Gulf Coastal Plain, and Ouachitas in Arkansas, Louisiana, Mississippi and possibly Tennessee. It also occurs on the Mobile-Tensaw Delta of Alabama. In stands of this association, <i>Liquidambar styraciflua</i> is codominant with <i>Quercus phellos</i> and <i>Quercus nigra</i>. <i>Quercus nigra</i> increases in importance on better drained sites.

Fagus grandifolia - Magnolia virginiana - (Pinus palustris) / Chasmanthium sessiliflorum Sandhill Streamhead Forest
» more details
accession code: urn:lsid:vegbank.org:commConcept:36144-{2B448630-31BD-4C2E-A61F-95AE127E04CB}
NatureServe Biotics 2019  2 This forest occurs west of the Mississippi River at narrow streamheads, lower slopes adjacent to sandy streambanks, and in the transition zone from bayheads to small stream forests. Due to juxtaposition between dry, sandy uplands (often with relictual <i>Pinus palustris</i>) and mesic stream courses, the flora of this community exhibits affinities to these different habitats. In addition, seepage is often present. The canopy of this association is dominated by some combination of <i>Magnolia virginiana, Magnolia grandiflora</i>, and <i>Fagus grandifolia</i>. A number of other deciduous species may also be present. A diverse herbaceous layer dominated by ferns, sphagnum moss, and sedges is usually present, ranging from sparse cover on the most uphill portions of this community to nearly 100% coverage in the wetter interior portions. Many of the species found in this type, including many of the herbs, are typical of "baygalls" or wet creek bottom habitats which invariably occur somewhat farther downslope.

Quercus alba - Carya tomentosa / Symplocos tinctoria / Mitchella repens Forest

accession code: urn:lsid:vegbank.org:commConcept:36148-{F97D0667-5508-4B3A-8F17-0C7E0F8C79C9}
NatureServe Biotics 2019  2 This forest community is located on small mima mounds within floodplains or flatwoods environments of the Upper West Gulf Coastal Plain of Arkansas, Texas, and possibly Louisiana. These mounds are topographically higher than the surrounding landscape and are found on somewhat coarser-textured soils. Dominant trees include <i>Quercus alba</i> and <i>Nyssa sylvatica</i> with <i>Acer rubrum var. rubrum</i> and <i>Carya tomentosa</i>. Scattered <i>Pinus taeda</i> are often present, the density of which is dependent upon past disturbance. <i>Cornus florida</i> is the dominant understory tree, rarely with <i>Sassafras albidum</i>. <i>Symplocos tinctoria</i> and <i>Hamamelis virginiana</i> are the dominant shrubs with <i>Asimina triloba, Callicarpa americana</i> (disturbed mounds), and <i>Vaccinium arboreum</i> occurring as occasional shrubs. <i>Parthenocissus quinquefolia</i> is the usual woody vine occasionally with <i>Smilax bona-nox</i> and <i>Vitis rotundifolia</i>. Dominant herbaceous species include <i>Chasmanthium sessiliflorum</i>. The herbaceous layer can be sparse due to low light levels and litter build-up. <i>Mitchella repens</i> is the common ground cover.
