Fagus grandifolia - Quercus alba / Ilex opaca var. opaca / Athyrium filix-femina ssp. asplenioides Forest
» more details
accession code: VB.CC.36471.CEGL007208
Martin, D. L., and L. M. Smith. ...  0 This mesic acidic forest of the West Gulf Coastal Plain is dominated by <i>Fagus grandifolia</i> and <i>Quercus alba</i>. It is further typified by the presence of a fairly diverse number of species which indicate high-quality mesic, acidic habitats in the region. The scattered to patchy tall-shrub stratum includes <i>Ilex opaca var. opaca, Carpinus caroliniana, Ostrya virginiana, Cornus florida, Styrax grandifolius</i>, and <i>Crataegus marshallii</i>. The sparse herbaceous layer includes <i>Polystichum acrostichoides, Trillium gracile, Prenanthes altissima</i> (uncommon), <i>Spigelia marilandica</i> (uncommon), <i>Galium circaezans, Desmodium nudiflorum, Uvularia perfoliata, Polygonatum biflorum, Arisaema triphyllum, Viola walteri, Mitchella repens, Tipularia discolor, Lilium michauxii, Smilax herbacea</i> (uncommon-rare), and <i>Podophyllum peltatum</i>.

Quercus rubra - Quercus muehlenbergii / Hamamelis virginiana / Polymnia canadensis Forest
» more details
accession code: VB.CC.35420.CEGL007215
Southeastern Ecology Working Gro...  0 This association represents forests on sheltered dolomite slopes in the Southern Blue Ridge with canopies dominated by <i>Quercus</i> spp., <i>Juglans nigra</i>, and <i>Magnolia acuminata</i>. However, a small amount of the canopy and understory is always composed of calciphilic canopy species more characteristic of areas west of the Blue Ridge, including <i>Quercus muehlenbergii</i> and <i>Juglans cinerea</i>. The dominant shrub is <i>Hamamelis virginiana</i>, but other shrubs include <i>Calycanthus floridus, Cornus alternifolia</i>, and <i>Hydrangea arborescens</i>. The herbaceous layer is lush and diverse, with typical species including <i>Impatiens</i> spp., <i>Hybanthus concolor, Polymnia canadensis, Laportea canadensis, Aquilegia canadensis, Adiantum pedatum, Sanguinaria canadensis</i>, and <i>Asarum canadense</i>.

Liriodendron tulipifera Ruderal Forest
» more details
accession code: VB.CC.34985.CEGL007218
Southeastern Ecology Working Gro...  0 This association represents early-successional, nearly monospecific stands of <i>Liriodendron tulipifera</i> in the southeastern United States. Examples are most common in the interior regions but also extend into portions of the adjacent Coastal Plain. Associates vary with biogeography but can include <i>Acer rubrum, Robinia pseudoacacia, Acer negundo</i>, and <i>Acer saccharum</i>. <i>Liquidambar styraciflua</i> is common in Coastal Plain and Piedmont locations. Vines can be abundant, including <i>Vitis</i> spp., <i>Smilax</i> spp., and <i>Parthenocissus quinquefolia</i>. Stands develop after a variety of anthropogenic disturbances across a wide variety of sites and soil types in a variety of mesic habitats, including along streams and on upland mountain benches. Stands with mixed species composition (generally mid- to late-successional) are covered by other associations.

Liriodendron tulipifera - Acer rubrum - Robinia pseudoacacia Ruderal Forest
» more details
accession code: VB.CC.35828.CEGL007219
Southeastern Ecology Working Gro...  0 This early-successional or semi-natural vegetation occurs at approximately 700-1220 m (2300-4000 feet) elevation in the southern Appalachian Mountains and Appalachian Plateaus. Examples are typical of areas which were once clearcut, old fields, strip-mined, graded for road construction, or otherwise cleared. Stands are typically revegetated from root and stump sprouts and wind dispersed seeds. Stands have canopies which are typically dominated by <i>Liriodendron tulipifera</i> and <i>Acer rubrum</i>, with lesser amounts of <i>Robinia pseudoacacia</i>. <i>Robinia pseudoacacia</i> is listed as a nominal to indicate the Appalachian distribution of this type. Associated species may vary. Some examples may contain <i>Pinus virginiana</i>. Tall shrubs (<i>Rhododendron periclymenoides, Rhododendron calendulaceum, Kalmia latifolia, Calycanthus floridus</i>) sprout from root stocks and occur as scattered, dense clumps, while shorter shrubs (<i>Gaylussacia ursina, Leucothoe fontanesiana, Rubus</i> spp., <i>Vaccinium</i> spp.) can have dense, continuous cover. Composition of the herbaceous stratum varies with site conditions and moisture regime and may contain field-adapted species, tolerant of high light intensities, as well as many shade-tolerant forest herbs. <i>Lycopodium digitatum</i> may also form dense cover.

accession code: VB.CC.35900.CEGL008391
Southeastern Ecology Working Gro...  0 Dense thicket composed of 1.5- to 3-m tall shrubs occupying the summits of the Pico Turquino massif. Typical species are <i>Ilex turquinensis, Myrica cacuminis, Persea similis, Lyonia calycosa, Peratanthe cubensis, Lobelia cacuminis, Torralbasia cuneifolia, Ageratina paucibracteata (= Eupatorium paucibracteata), Vernonia parvuliceps</i>, and <i>Vernonia praestans ssp. cacuminis</i>.

Paspalum monostachyum - Andropogon glomeratus - Schizachyrium littorale - Iva texensis Herbaceous Vegetation
» more details
accession code: VB.CC.34726.CEGL007222 NOT CURRENTLY ACCEPTED
Southeastern Ecology Working Gro...  0 This community is described from Padre Island, Texas. It represents grasslands dominated or codominated by <i>Paspalum monostachyum</i> that occupy slightly lower parts of barrier flats. Other herbaceous species that may be present in high cover and occasionally codominating include <i>Schizachyrium littorale, Andropogon glomeratus</i>, and <i>Iva texensis</i>. Associated species include wetland herbs such as <i>Hydrocotyle bonariensis, Conoclinium betonicifolium</i>, and <i>Spartina patens</i>. It grades into and may be hard to distinguish from ~<i>Schizachyrium littorale - Paspalum monostachyum</i> Herbaceous Vegetation (CEGL002207)$$ which occupies slightly higher and drier positions on the barrier flat.
