Comm #12693	Hypericum lissophloeus Shrubland » more details accession code: VB.CC.35933.CEGL003870	Southeastern Ecology Working Gro...	0	This association represents ponds in Bay and Washington counties in the Panhandle of Florida dominated by <i>Hypericum lissophloeus</i>. This species is a narrow endemic found only in these counties, but where present it may form a shrubland (1-4 m tall) of varying density along the margins of certain depressions. These depressions have been called sinkholes or sandhill ponds. They are apparently of karstic origin but have extensive sandy soils covering the margins and, therefore, exhibit little direct evidence of calcareous conditions or of limestone. Examples may be seasonally flooded to depths of as much as 1.5 m deep, but they dry down regularly as well. These are fairly large, steep-sided depressions with as much as 30 m elevation change from rim (sandhill) to center. Other shrub species include <i>Chrysoma pauciflosculosa, Hypericum reductum</i>, and <i>Lupinus westianus var. westianus</i>. Typical herbs include <i>Panicum virgatum, Andropogon glaucopsis, Andropogon capillipes, Panicum hemitomon, Centella erecta, Dichanthelium</i> spp., <i>Lachnocaulon minus, Ludwigia suffruticosa</i>, and <i>Eleocharis</i> spp. Other herbs may include <i>Chrysopsis lanuginosa, Drosera filiformis, Drosera brevifolia (= Drosera leucantha), Eriocaulon</i> spp., <i>Rhexia mariana var. mariana, Rhexia salicifolia, Syngonanthus flavidulus</i>, and <i>Xyris baldwiniana</i>.
Comm #12694	Quercus pagoda / Ulmus crassifolia - Celtis laevigata / Carex cherokeensis Forest » more details accession code: VB.CC.23706.QUERCUSPAGODAUL	Southeastern Ecology Working Gro...	0	This riparian forest occurs along the periphery of the West Gulf Coastal Plain on rich, often calcareous alluvium. The canopy of typical stands contains Quercus pagoda and Liquidambar styraciflua, with Ulmus crassifolia and Celtis laevigata in the understory. Carex cherokeensis is a characteristic herb. The midstory is dominated by Celtis laevigata, followed by Ulmus crassifolia and Ulmus alata. Other dominant or frequently encountered species include Sabal minor, Ulmus alata, Crataegus spathulata, Crataegus viridis, Ilex decidua, Ilex vomitoria, Fraxinus americana, Rubus trivialis, Smilax bona-nox, Toxicodendron radicans, Chasmanthium latifolium, Campsis radicans, Elymus virginicus, Geum canadense, and seedlings of Quercus pagoda, Celtis laevigata, and Quercus nigra. Shrubs include Symphoricarpos orbiculatus, Forestiera ligustrina, and Sanicula odorata (= Sanicula gregaria).
Comm #12695	Artemisia bigelovii Shrubland Alliance » more details accession code: VB.CC.24293.ARTEMISIABIGELO	Western Ecology Working Group of...	0	Stands included in this dwarf-shrubland alliance are found on the Colorado Plateau and in southeastern Colorado. Sites include gentle to moderately steep shale hillslopes and mesas in Arizona and breaks and shale plains in the shortgrass steppe west to the foothills near the Colorado Front Range. Soils are typically shallow, well-drained, calcareous loams, clay loams, and clays derived from limestone, sandstone, shale and alluvium. The soil surface has high cover of bare soil and rock. The vegetation is characterized by a sparse to moderately dense dwarf-shrub layer that is dominated or codominated by Artemisia bigelovii. Dwarf-shrub associates from the shortgrass steppe include Yucca glauca, Krascheninnikovia lanata, Frankenia jamesii, and Glossopetalon spinescens var. meionandrum, which may be present to codominant. On the Colorado Plateau, stands may be codominated by Ephedra spp., Eriogonum corymbosum, Parryella filifolia, or Purshia stansburiana. Gutierrezia sarothrae and species of Atriplex and Yucca are common in most stands. Scattered Juniperus spp. trees are occasionally present. A sparse to moderate graminoid layer is usually present. Dominant grasses include Aristida purpurea, Achnatherum hymenoides (= Oryzopsis hymenoides), Bouteloua gracilis, Hesperostipa neomexicana (= Stipa neomexicana), Pleuraphis jamesii (= Hilaria jamesii), Sporobolus cryptandrus, or less commonly Pascopyrum smithii. On the Colorado Plateau forbs are generally sparse. However, cushion plants are common on shortgrass steppe slopes. Other forbs, such as Astragalus missouriensis, Heterotheca villosa, Melampodium cinereum, Picradeniopsis oppositifolia, Stanleya pinnata, and Zinnia grandiflora, are usually present. Exotic annuals, such as Bromus japonicus, Bromus tectorum, Salsola kali, and Descurainia sophia, may be present to common depending on disturbance, and amount and season of precipitation. Diagnostic of this alliance is the Artemisia bigelovii-dominated or codominated dwarf-shrub layer.

Comm #12698	Acacia rigidula Shrubland » more details accession code: VB.CC.36370.CEGL003874	Southeastern Ecology Working Gro...	0	This association is broadly defined to include shrublands occurring over a range of shallow soils (gravels, sands, heavy clay), in the uplands of the South Texas Plains and the coastal bend area of the Gulf Coast Prairies and Marshes of Texas. Associated shrubs depend on soils, slope, and cultural influences but can include <i>Acacia berlandieri, Prosopis glandulosa, Prosopis reptans, Celtis pallida, Ziziphus obtusifolia var. obtusifolia, Diospyros texana, Mahonia trifoliolata (= Berberis trifoliolata), Condalia hookeri, Zanthoxylum fagara</i>, and <i>Acacia</i> spp. Herbaceous vegetation within mottes is usually sparse but may include <i>Leersia monandra</i> and <i>Setaria leucopila</i>. These shrublands often occur as mottes that are intermixed with other shrublands or woodlands dominated by <i>Acacia berlandieri, Celtis pallida</i>, and <i>Prosopis glandulosa var. glandulosa</i> and with coastal grasslands characterized by <i>Buchloe dactyloides, Bouteloua rigidiseta, Aristida purpurea, Bothriochloa barbinodis, Sporobolus compositus var. compositus, Bothriochloa longipaniculata, Bothriochloa laguroides, Chloris pluriflora, Schizachyrium scoparium</i>, and <i>Nassella leucotricha</i>.

Comm #12700	Pueraria montana var. lobata Vine-Shrubland » more details accession code: VB.CC.35568.CEGL003882	Southeastern Ecology Working Gro...	0	This vine-dominated vegetation is dominated by <i>Pueraria montana var. lobata</i>, a fast-growing vine native to Asia. The species was introduced into the United States in 1885, primarily as an ornamental and as a potential source for cattle forage. It was subsequently widely used for erosion control in the southeastern United States. This association occupies a variety of sites throughout most physiographic provinces in the Southeast, ranging in size from less than a hectare to 5-10 hectares or more. It chokes out existing vegetation. Edges of examples of this vegetation may consist of small to large trees in the process of being overwhelmed by kudzu. More than 2 million acres of forest land in Alabama, Georgia, Mississippi, Tennessee, North Carolina, and South Carolina are estimated to be infested with kudzu. This association is also known to occur north to central Kentucky, Virginia, and Maryland, and as far west as eastern Texas and Oklahoma.
